Create Outlet PointsUsing the basin water right coverage as a guide, outlet points were created along the stream network in order to form control points for the eventual watershed delineation:

Subtask on Network Analyst

For Starters...
This is the Guadalupe River Basin, after using CRWR-Preproon it and vectorizing the stream links.
![Page 13: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/13.jpg)
It was a good test case because...
• Density--I wanted a small data set to learn with
• NO GAPS--Network Analyst doesn’t handle gaps or lakes well.
• Availability--I had already done the Prepro work for class...
![Page 14: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/14.jpg)
Add some Points of Interest
These are evaporation stations from a coverage of Texas. In a real analysis,these might be water rights, point sources, stream gages, etc...
![Page 15: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/15.jpg)
Use Network Analyst
This shows the results of route planning from a point to the outlet.
![Page 16: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/16.jpg)
Cool Stuff
• Network analyst can be made to look only downstream
• Network analyst can be made to look only upstream
• Network analyst can look both ways
• It can show you hydrologic connectivity
• It doesn’t require that input data be digitized
• It handles points not EXACTLY on the network
![Page 17: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/17.jpg)
Caveats
• Network is very sensitive to digitizing errors
• Won’t show you WHERE connectivity is broken
• Files must be prepared properly (From Nodes and To Nodes)
• Aimed at transportation, not rivers

Current Research Status• Drafting dissertation proposal• Objective is to develop the spatial risk
assessment methodology– Spatial Risk Assessment (SRA) is the process of
identifying and quantifying the potential for adverse effects to human or ecological receptors from chemicals or radioactive materials released to the natural environment within a spatially-referenced, integrated modeling environment
![Page 39: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/39.jpg)
Necessary Elements of the SRA Methodology

Update on Patrice’s Work
• Have written about 25 pages; mostly database development and hydrology part.
• Assumptions made about BMP effectiveness and current level of implementation (based on 1991 Rural Clean Water Progress Report).
• Using Summarize by Zones, backed out to EMC for CAFO land use to match E&S averages for 5 basins - see next slides for data
• Calculated bay volumes and detention times for low, average, and high tides - see last slide for data.
• Doing literature search to support EMC values.
• Outline of report being written to help focus writing effort.

Miami River Data - Analysis using
Summarize by Zones
• Runoff Conc values linked to spreadsheet on previous slide. Model runoff conc for CAFOs changed to get reasonable results for predicted concentration for each of 5 watersheds.
• Kilchis, Tillamook, and Trask are somewhat overestimated. Wilson is somewhat underestimated.

Soil Moisture Modeling in HEC-HMS

Objective
The objective of my research is to use spatial data to develop soil moisture accounting schemes for the Tenkiller Watershed using ArcView and a prototype model in Visual Basic called the Soil Water Balance Modeling System (SWBMS) developed by Sean Reed.
![Page 86: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/86.jpg)
Required Data
Existing STATSGO and SSURGO soil databases for the Tenkiller Watershed
A Nexrad cell mesh for the Tenkiller Watershed
![Page 87: GIS in Environmental and Water Resources Engineering Research Progress Report Oct 30, 1998.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649e865503460f94b899ae/html5/thumbnails/87.jpg)
AnalysisArcView will be used to preprocess soil and
land cover data with scripts created by Sean Reed. This preprocessed data will then be used as input data for SWBMS. The results of the water balance will then be compared to results which are produced by HEC-HMS. This comparison will help determine what modifications to the model are needed, if any.

Terrain Modeling
• Map cross-sections
• Create cross-section bounding polygon
• Convert DEM to points
• Intersect DEM points with bounding polygon
• Delete selected points
• Form a TIN: cross-section points control the channel and floodplain, DEM points control elsewhere
• Problems: ragged zone of transition, bridges/culverts

Query Builder
Download
Here, you access data from the Web. Or you can open ArcExplore,a free download software,to do the some job.
I suggest don’t use Identify tool to query red one, because there are many data on the same location. Using Query builder is more efficient. if you like, you can query blue one which only contains geographic information to know which well is in where.

Query Builder
1. Want to know the Benzene monitoring result of well “OW-WR-19”.
2. Condition 1 and concentration higher than 0.005
and need all information.
3. Handle the query result. Two ways: (1) save as text file
(2) directly drag into Word or Excel.
