    While brainstorming my shear force and bending moment diagrams for an

    exam in my structural analysis course, I was confounded by why my bending moment

    diagram did not conclude at zero, rendering the system to be statically unstable and

    furthermore yielding an invalid solution to any structural engineering reality. Mysupport reactions indicated stability by equating the system to be zero and my shear

    force diagram agreed. I assumed my error was in formulating my bending moment

    equations for some section of the beam and I fruitlessly reevaluated the equations

    until my time expired. In my haste, I overlooked an error in my algebra near the

    beginning of my work. While two plus three equals five, another possible solution

    may be seven minus two equals five. This demonstrates that additive properties such

    as those displayed with shear may seemingly have more than one solution. My shearsolution was the wrong solution because it affected my bending moment to finalize at

    a non-zero number. A simple error of having a positive number represented by a

    negative number caused a handful of points to be deducted from my exam. However,

    such a simple calculation error in reality would compromise a bridge or a skyscraper,

    and moreover a career.

    Often in life a problem will seemingly have many solutions. More often a

    particular solution will prove itself to be the most sufficient of a set of solutions while

    some solutions (perhaps some of the remaining ones) will cause further problems or

    imprint problems that will later be recognized in hindsight. Several answers are

    discovered in the classroom while many are learned throughout life experiences.

    Numerous questions have been satisfied by our ancestors while countless still remain

    a mystery to current generations. Ultimately, before any dilemma can be truly

    resolved, the problem should be thoroughly understood. A hasty solution may

    provide a short-term solution yet may additionally generate devastating and possibly

    irreversible long-term effects. Similarly, before the topics of centralization and

    privatization regarding public water works are debated, I invite you to the analysis of

    the pressing concerns with the nations and the worlds water resources as well as in

    the depths of history.

    Before engineering became subdivided into many distinct disciplines as it is

    now, it was broadly the field of either civil engineering, pertaining to civilian or

    public works, or military engineering, pertaining to military works. Amongst many

    functions, civil engineers would build homes, towns, cities for civilians to live in,

    roads, highways, bridges to transport people and goods between places, and water

    treatment plants and water distribution plants to provide clean water to a population.

    Civil engineers now customarily specialize in a civil engineering sub-disciplines.

    Geotechnical and structural engineering focus on

    designing the many foundations from which

    structures stand and the many building frames that

    provide shelter. Transportation engineering centers

    various modes of transportation between rural and

    urban areas for commercial and residential uses.

    Environmental and hydraulic engineering aims to

    restore and replenish natural resources and

    distribute these resources in the most optimal ways

    to support both the needs of mankind and the needs of the environment around us.

    Current military engineers now commonly start their study as civil engineers

    alongside civilians at accredited colleges and universities; where the duties eventually

    diverge for example is providing shelter for the public or providing shelter for U.S.

    troops. Conversely, where the duties converge is to the oath and obligation of

    providing and protecting the general interests and the well-being of Americans.

    Figure 1: Civil Engineering Students atWest Point. Founded in 1802, theUnited States Military Academy at WestPoint was the first school in the U.S. tooffer a formal program of instruction inengineering.

    From ancient history to modern day, engineers are valued to be the strong

    foundation of civilizations. Homes accommodate civilians with shelter for their

    families and buildings supply merchants with a marketplace for their business. Roads

    and bridges provide transportation for people and the goods people need in and out of

    cities and towns, rural and urban alike. Irrigation systems, aqueducts, or dams were

    5

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    6/18

    instruments utilized to transport water to lands for crops or to people for drinking,

    bathing, cooking, and cleaning. All of these systems, buildings, transportation

    systems, and producing fare, compile to form a functioning community and as one

    part fails, the others are hindered or in many cases fail as well. As an engineer is

    responsible for designing and constructing these means, if they prove to be

    unsustainable and render to be eventually useless then the fault of that failure may

    reflect on the engineer.

    For example when Austen Henry Layard, a British archaeologist, visited a

    region rich with history since the times of Mesopotamia known as Nippur on detour

    from his excavations in Assyria in January 1850, he sought the dunefields of Hilla

    which were renowned to be formed within only the previous thirty years over what

    once was fertile marshlands. Layard once

    detailed, it was possible to go all the way to

    Nippur by boat down the Euphrates, across

    major branch canals and then across the

    marsh. (Brandt 68) He boasted of the plant

    life, wildlife, and communities which were

    synonymous to numerous historical accounts

    of that time. By 1889, Brandt later

    documented that drastic changes had

    occurred in the landscape. It was impossible to get supplies by boat from Hilla to

    Nippur. The channels were almost completely dry, and the local inhabitants were

    desperately digging wells in the river bottom. (68) Brandt concluded that Both

    marshes and dune zones are prominent environmental features directly related to

    irrigation agriculture and, more broadly, water managementDunes developed

    around tamarisk stumps and seemed to begin as small piles of drifted material at the

    edges of cultivation. For miles there was evidence of recent desertion of the land and

    Figure 2: Canal at Bassorah

    7/18

    encroachment of dunes. (69) Where water thrives, produce thrives, towns and

    businesses thrive, and civilizations both of small or grand size are born. The paradox

    great civilizations have fallen before to wars over fertile land and once flourishing

    civilizations that seemed impeccably sustained during their time have crashed from

    over exhaustion at a magnitude just as grand or even greater than as they started.

    Mesopotamia is considered one of the earliest technologically and culturally

    advanced ancient civilizations and is credited for engineering the first wheel. In those

    times, the civilizations needed water to farm those lands to furthermore feed their

    families and commune in a society that revolves around this production. Civilizations

    that prospered were ones that were able to engineer ways to yield and deliver

    resources where necessary. While technology was booming in its time, technology

    was still far from what is considered advanced now. Perhaps the people were not

    excessive but the technology certainly was not sustainable. More likely the case now,

    a US home and town will have an overabundance of food and choices. Americans in

    these times will have refrigerators full of wasted foods (25% of all food is wasted or

    about 96 billion pounds of annually wasted food in US N), cabinets stocked with

    bottled water at hand (gallons of water consumed annually in the US increased from

    less than 400 thousand in 1976 to over 3.3 million in 1997 to over 8 billion in 2006 N),

    and many homes furnished with air conditioners, dishwashers, multiple bathrooms,

    luscious lawns, or lavish swimming pools. Our needs are certainly sufficed. Our

    energy and resource use is collectively excessive. Our technology is very advanced.

    Our water resources are currently being depleted at an unsustainable rate. Many

    people, especially Americans as a top world multiple-resource consumer, may afford a

    comfortable life now but cannot afford to turn a blind eye to the diminishing and

    mishandling of such a precious natural resource as water that will affect not only our

    own future and civilization but mankind worldwide.

    Americans have tapped into a hidden,

    massive treasure chest of water which spans

    across eight states including Wyoming, South

    Dakota, Nebraska, Kansas, Oklahoma, Texas,

    New Mexico, and Colorado the Ogallala

    Aquifer. The region once called the Great

    American Desert by conquistador Coronado

    in 1541 is now called the Great Plains or the

    High Plains; the semi-arid land, infertile

    without the assistance of irrigation, was once

    valued useless for farming is now considered

    one of the leading agricultural areas of the

    world. This underground ocean contains

    enough water to fill Lake Erie nine times and

    sprouting at the ground surface is over fourteen million acres of crops which

    accumulate about one-fifth of Americas total annual agricultural harvest. (Ashworth

    10) William Ashworth, author of Ogallala Blue, warns, Five trillion gallons of water

    are drawn from the Ogallala annually - about 30% of all groundwater used for

    irrigation in the United States Water is being pulled out much faster than it is being

    put back in. Since widespread irrigation began in the 1950s, the Ogallala has sustained

    a net loss of as much as 120 trillion gallons 11 percent of its original volume. (11)

    This water is used to irrigate land (mostly semi-arid), to grow produce, to feed

    livestock, to provide drink and to fuel recreation. The water in Ogallala Aquifer,

    which is considered a renewable resource, is originally a result of the melting glaciers

    of the Ice Age and can be replenished by groundwater discharges or seepage from

    precipitation. The significant reduction of this resource is due to a faster depletion

    rate than its recharge rate.

    Strikingly similar to Mesopotamia with water resource fatigue is the

    agricultural and municipal standard of living which is demonstrated by Karl W.

    Butzer in his commentary of Human Impact on the Environment: Ancient Roots,

    Current Challenges. He states, The implications of agricultural lifeways for new

    environmental adaptations are illustrated [one] example is ancient Mesopotamia,

    where overirrigation during the period of centralized control under the Ur III

    Dynasty led to salinization and declining productivity from 2400 to 1700 B.C. [The

    Ur III] efforts represent metastable systems predicated on centralization and

    maximization, and their collapse led to scaling back and diversification that better

    served long-term productivity. (176) Likewise, if Americans cannot learn to well

    manage the use of our natural resources, we may be forced to manage or mitigate by

    nature.

    The World Health Organization reminds us that in a world with a population

    Figure 5: Global Water Stress 1995 (actual) and 2025 (virtual)

    10

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    11/18

    of over six billion people, over one billion people do not have access to potable

    drinking water. (3) The modern awareness of the limited resource of potable water

    has rightfully earned water the label blue gold just as petroleum currently wears the

    label of black gold. Ashworth concurs, Groundwater is a mineral, and like most

    minerals it has practical value. Mining it is a means to realizing that value. (11) Gold

    propelled people out on mining frenzies for its value in the market. Petroleum has

    fueled territorial wars for decades. However, gold in contrast to petroleum and water

    is a luxury not necessary for life to exist. Petroleum though a highly dependable non-

    renewable resource can be greatly reduced in demand by alternative energy sources,

    recycling of petroleum based products such as rubber, and better energy efficient

    technologies. According to the U.S. Energy Information Administration, Americans

    consume 35% of the worlds oil production with 20,687 thousand barrels expended a

    day. In comparison, Americans alone trump the remaining fourteen top world oil

    consumers averaging at 2,756 thousand barrels a day by 17,931 thousand barrels. If

    water takes on a prized value as petroleum has when its demand skyrocketed past the

    supply, we can anticipate similar challenges. Petroleum, in the end, can be replaced

    with alternative energy sources while water will always be in demand as it is essential

    for life. Ashworth reiterates, WATER IS LIFE. It is our primary support system, the

    chief component of our tissues, and the only substance that all living things must

    have or die. There are bacteria that can live without oxygen; there are cave creatures

    and deep-sea dwellers that can live without sunlight. Nothing can live without

    water. (9) The depletion of gold was a factor in the inflation of the US dollar by the

    overproduction of quantities of money insufficiently based on the obtained quantity

    of gold in response to augmented demand. The wasteful usage of petroleum may

    eventually force Americans to reinvent their lives to environmentally practical

    measures if we do not reevaluate our current overuse and high demands. Water,

    being almost absolutely inelastic in comparison, however will not have as much

    11

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    12/18

    mercy. Ashworth agrees, Groundwater overdraft is not an accident here; it is a way

    of life. But because it means that the water will someday disappear, it is also a way of

    death. (11) The analysis of water consumption should be a concern of today and not

    tomorrow. If we run out of petroleum we would not even have the energy to sustain

    desalination plants with our currently practiced technologies which furthermore

    negatively impact marine ecology. It is an imperative to manage a sustainable usage of

    water now and to exercise viable demands that cater primarily to our needs rather

    than our wants.

    When presently examining a development, project managers and authorities

    subdivide the efforts needed to complete the endeavor and will delegate duties

    accordingly. An engineering plan will customarily circulate through planning, design,

    and construction phases. Depending on what sub-field or related field of engineering

    is of tailored concentration per a particular person determines the scope of work for

    that person and it is not conventionally practiced to overextend ones delegated

    duties. Similarly, a market and a government serve a purpose and neither should truly

    behave like each other or breach their scope of work. A market serves a society and

    without people a market is not sustained. A government serves a people and without a

    government a society, as history defines, is not

    conventionally sustained. A market is profit driven

    and a government is need driven. A market

    stimulates economic growth, the growth of a

    business, and the growth of a city or town. A

    government protects the well-being of a people, their

    businesses, their cities and towns, their lives and

    prosperities. Water is a resource and not a product,

    and furthermore water is a necessity and not an

    amenity. With this in mind it is easy to determine the realm of work should be

    Figure 6: Water bottles are moneyconsumers.

    12

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    13/18

    allocated to the government. Our water should be protected and be available equally

    to all persons. All people have the right to water and businesses should never

    challenge that right.

    America seems to be fiscally deteriorating. Concerns are debated over the

    expenses of our country being at war. Economists loom about the fragile market. Sick

    citizens often cry for more aid with their health bills than their health. Meanwhile

    our Earth is suffering and our environments are oversaturated, polluted, and

    unsustainable. If we were cautious as a society of the pollutants that we put in the air

    by emissions and that we put in the water by chemical treatments of our soils or by

    erroneous disposing of our wastes perhaps our health and the ecology surrounding us

    would not be compromised. If we were conservative with how we spent our money,

    with how much energy our homes, cars and lives consume or with how much

    unnecessary cosmetics or products we collect that take immense amounts of energy

    just to be made available, we would have a significantly lower demand for goods and

    resources in the market and our market would furthermore not be so easily shaken.

    We are fighting a war in a country that does not even have access to clean water, that

    does not have reliable electricity, that does not have adequate schools for their

    children, that has an extremely outdated infrastructure, that considers meat a rare

    luxury and struggle to feed their war-broken families, and the list goes on. These same

    Iraqis have endured decades of oppression from the radicals amongst them. These

    Iraqis are the people we are fighting to secure, by rebuilding their unstable

    infrastructure, by providing water treatments plants to offer them potable water to

    drink, by providing electricity to hospitals, police stations, and homes, by providing

    schools with actual floors and roofs for children to learn within, by providing security

    to the community so they may run their own markets, their own churches and

    hobbies in peace. By retreating now, it would be like taking the crutches away from

    someone whose legs have not healed yet. While we have the luxury to exercise our

    13

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    14/18

    liberties and enjoy the comforts our society offers even while we are in what is

    considered a financially challenging state, we should consider the good that may

    come out of our adversities and learn from the things that have proven to be

    hindrances. By securing them and building a foundation of peace overseas, we hope

    to be securing ourselves from the radicals that oppose our lifestyles and that have

    successfully targeted our soils. In marketing terms, we should view our efforts in Iraq

    as an investment with long-term benefits and a retreat as a quick-fix that may have

    short-term benefits but additionally long-term instabilities.

    Privatization during an era of globalization does not go merrily together unless

    you are on the profit receiving end of the bargain. Maude Barlow of the International

    Forum on Globalization contributes, Everything is for sale, even those areas of life

    once considered sacred, such as health and education, culture and heritage, genetic

    codes and seeds, and natural resources such as air and water. Increasingly, these

    services and resources are controlled by a handful of transnational corporations who

    shape national and international law to suit their interests. The Washington-based

    Institute for Policy Studies reports that the top two hundred corporations are now so

    big that their total sales surpass the combined economies of 182 countries and they

    have almost twice the economic clout of

    the poorest four-fifths of humanity. Of

    the 100 largest economies in the world,

    53 are now transnational corporations

    The richest fifth of the world's people

    consumes 86 percent of all goods and

    services, while the poorest fifth

    consumes just over 1 percent.

    Privatizing the resources needed for life

    make the market the referee amongst

    Figure 7: Men struggle to draw water from a drying

    well in Rabdore, Somalia, where rival clans fought a

    two-year war over the water supply.

    14

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    15/18

    battling consumers, a referee who profits from that high demand. That battle could

    translate into wars as it already has demonstrated in third-world or poor countries.

    Our focus should be on maximizing governments efficiency not on transferring the

    reins of control. The time wasted in transition could be better used to fast-forward

    the current research and technologies to implementation. Incentives should be

    encouraged in Congress as well as practiced in our law. On an individual level, we

    should re-evaluate our personal energy and resource consumptions and live

    conservatively, not only for the sake of our disadvantaged counterparts but for our

    future.

    In conclusion, the rise and collapse of civilizations has repeated itself

    throughout the course of history. This paper attempts to analyze the trend. Are

    societies governed by capital or resources? If there were no valuable resources would

    there be any capital? Capital will likely mitigate as it has to another region that offers

    resources. However, while water is a resource people cannot afford to deplete, capital

    would not have anywhere to mitigate if its supply was diminished and furthermore

    life could not be sustained. While America might not endure the pressures of

    insufficient water supplies now, it is a fair and probable possibility we will. Ashworth

    warns, Some of the consequences of groundwater mining are environmental: springs

    dry up, rivers diminish, the numbers and varieties of plants and animals are reduced.

    Some are economic: increased pumping costs as wells deepen, increased food costs

    and decreased land values as crops shrink. And some are human. The human costs

    may include bankruptcies, foreclosures, and forced migrations. They may include

    failed businesses and abandoned towns. They are not likely to include thirst

    municipal water systems will be among the last users of Ogallala water but they

    may well include starvation. (12) While wars spread through poor countries like

    viruses, others look to us for aid. Many of them are environmentally and

    economically torn, suffering from starvation and thirst and facing fallen markets and

    15

  • 8/3/2019 Knee Deep Pocket Deep: Waters role as a resource and waters promise as a product

    16/18

    fighting for their homes and lives. As a wealthy

    nation we may not be responsible for assisting

    other nations in need, but as humans and for the

    sake of humanity we need to place our values

    primarily on life and consider the positive effect

    we can have with assisting our neighbors as well

    as the negative effects that may translate over

    political boundaries. While lending a fraction of

    our wealth to the needy, we need to invest the

    remainder into our own domestic sustainability.

    It is imperative that America shifts from a nation

    that strictly abides by intervention rather than

    prevention. Critics may argue that the government contributes to the issue. Subtract

    the government out of the scheme and inevitably by our lifestyles, the issue still

    exists. Rather, the government provides solutions and programs to preserve or protect

    the American ways of life and our interests. Improving the implementation of

    preserving our resources and using them wisely, as well as maintaining the foresight

    of the future for generations ahead, is a necessary objective of our government and

    must be taken into serious priority now while the great seeds of our future must be

    sown.
