1 Watershed Parameters for Water Rights in the Trinity River Basin Melissa Figurski CE 394K

2 Project Goal Determine Watershed Parameters for Water Rights in the Trinity Basin Upstream Area Average Upstream Precipitation Average Upstream Curve Number

3 Purpose Water Availability Modeling State Mandated Resource Planning and Management TNRCC, CRWR, and Contractor

4 Data Requirements 30-meter Digital Elevation Model (DEM) Stream Network Water Right Locations Curve Number Grid Precipitation Grid

5 Previous Method Wrap1117.apr Developed by Brad Hudgens 6 Basins completed with Wrap1117

6 Trinity River Basin

7 Why not use the old method? 237 million grid cells 11-day processing 1649 water rights

8 New Idea Separate the Trinity into smaller watersheds (HUCs) Use Wrap1117 on individual HUCs Account for upstream contributions with ArcInfo 8

9 Procedure

10 Delineate HUC Watersheds Burn stream network into DEM Locate outlet points for each HUC Buffer each HUC Clip burned DEM to buffered HUC Run ArcInfo workstation ‘fill’, ‘flowaccumulation’, and ‘watershed’ commands on each buffered HUC

11 Outlet Points Locate Outlet Points for each HUC

12 Buffer HUCs and Clip DEM 5000 meter bufferClipped DEM

13 ArcInfo Workstation Functions Fill burned DEM Determine flow direction and flow accumulation Delineate HUC watershed Flow Direction+Outlet Cells=Watershed

14 Completed Delineation

15 Delineation Problems

16 Gather Data Select water rights and stream network in HUC 12030102

17 WRAP1117 Flow direction stream network

18 WRAP1117 Snap Points to Stream Network

19 WRAP1117 Average PrecipitationAverage Curve Number

20 WRAP1117 Create Network Schematic

21 WRAP1117 Delineate Incremental Watersheds

22 WRAP1117 Read Water Right Parameters

23 Future Work

24 ArcInfo 8 Create network

25 ArcInfo 8 Set flags at inlet and outlet ‘Find Path’ between outlets Export water rights on path Add upstream data in table

26 Summary New method needed Segment basin into HUC units Run Wrap1117 on individual HUCs Use ArcInfo 8 to account for upstream data
