WMS Modeling Tips for Texas Department of Transportation
NSS
The TXDOT Regression Equation for watersheds in rural areas is listed in the NSS program as "Peak Rural Statewide 2009 5087". The equation requires the following parameters:
- Drainage Area: Computed by WMS
- Main Channel Slope: Computed by WMS, currently needs to be transferred manually from basin data parameters to NSS window.
- Mean Annual Precipitation: Derived from a map located at the TNRIS website. You can also download the shapefiles directly from here. A mean annual rainfall grid for the state of Texas has been developed from this map and can be loaded directly into WMS.
- OmegaEM residual from 2009 5087: Derived from a map located in this report. A link to the report is also contained on the USGS Documentation Site for NSS
