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 http://tg-twdb-gemss.s3.amazonaws.com/d/hydro/tx_precip.zip] website. You can also download the shapefiles directly from [here http://tg-twdb-gemss.s3.amazonaws.com/d/hydro/tx_precip.zip]
- OmegaEM residual from 2009 5087: Derived from a map located in [this http://pubs.usgs.gov/sir/2009/5087/pdf/sir2009-5087.pdf] report
