1WATER- The Source of Life

All the water that will ever be is, right now. -National Geographic

Water has become a highly precious resource. There are some places where a barrel of water costs more than a barrel of oil. - Lloyd Ax worthy

2WHAT IS WATERSHEDA watershed is a basin like landform defined by peaks which are connected by ridges that descend into lower elevations and small valleys.

It carries rainwater falling on it drop by drop and channels it into soil, rivulets and streams flowing into large rivers and in due course sea.

It affects the people living downstream of

It is a synonym of catchment or basin of a river coined for an area restricted to 2000sq. Km.some natural watersheds

CHARACTERISTICS OF WATERSHEDS

SIZE: It helps in computing parameters like precipitation received, retained, drained off.

SHAPE: Different shapes based on morphological parameters PHISIOGRAPHY: Lands altitude and physical disposition.

SLOPE: It controls the rainfall distribution and movement:

CLIMATE: It decides the quantitative approach.

DRAINAGE: It determines the flow characteristics and so the erosion behavior.5CHARACTERISTICS OF WATERSHEDS

VEGETATION: Information of species gives a sure ground for selection plants and crops.

GEOLOGY AND SOILS: Their nature determines size, shape, physiographic, drainage and groundwater conditions.

HYDROLOGY: Basic to final goal of growing greenery in a watershed. It helps in quantification of water available.

HYDROGEOLOGY: Availability of groundwater.

SOCIOECONOMICS: Statistics on people and their health, hygiene, wants and wishes are important in managing water.6WATERSHEDSHED MANAGEMENTIt involves management of land, water, energy and greenery integrating all the relevant approaches appropriate to socioeconomic background for a pragmatic development of a watershedConserving soil and water

8The Triple Benefits of a Healthy Watershed Ecological Health A healthy, intact watershed minimizes the impacts of flooding and erosion and serves to filter sediments and contaminants so they do not reach our streams, lakes, and groundwater.

Economic Health Clean water allows municipalities, businesses, agricultural producers, and industries to operate more cost effectively, saving money for taxpayers and consumers

Human Health Life requires a safe daily supply of water. But water is far more than that: clean surface and ground water is essential to support our high quality of life and the social aspects of our communitiesBasic cycle of water management

WATER QUALITY

LAND USEYOU have the AUTHORITY to protect the water resources in YOUR community!

LOCAL OFFICIALS Water planningWater quality can or can not be impacted by the land use in the watershed. Land use is decided by a communitys local officials, and therefore, they have the authority and control to protect water resources in the community.

Water quality can or can not be impacted by the land use in the watershed. Land use is decided by a communitys local officials, and therefore, they have the authority and control to protect water resources in the community.
