Evaluating Water Quality Parameters associated with Urbanization using BASINS 3.0 Kristi Shaw Water Quality Standards to Monitor for Urban Development (30 TAC 216) Total Suspended Solids Total Nitrogen Total Phosphorous

Chemical Oxygen Demand Biochemical Oxygen Demand (BOD) The BASINS Experience BASINS 3.0 Capabilities Data extraction tools and project builders Water quality assessment tools (TARGET and ASSESS) to address small scale characterization needs Watershed Delineation tools

Utilities to classify DEMs, land use, and soils SWAT and HSPF (both watershed loading and transport models) QUAL2E (instream water quality model) PLOAD (one dimensional model that estimates nonpoint pollution loads) Fecal Coliform Levels Exceeding Texas Regulatory Criteria in 1989 using ASSESS Delineating watersheds

HSPF QUAL2E PLOAD SWAT (Soil Water Assessment Tool) Physically based model developed to predict the impact of land management practices on water, sediment, and

agricultural chemical yields on complex watersheds Considers varying soils, land use, and management conditions Assimilates point source contributions Performs flow and water quality routing in stream reaches Classifying land use Distribution of Hydrologic Response Units

SWAT View HSPF (Hydrological Simulation Program Fortran) ver 1.2 watershed model that simulates nonpoint source runoff and pollutant loadings for a watershed combines these with point source contributions performs flow and water quality routing in reaches.

GenScn GenScn (selecting multiple records of 31625- Fecal Coliform) Genscn (selecting multiple records of Nitrogen TKN) Conclusion Basins 3.0 is still in development phase and has programming glitches

The HSPF and SWAT model learning curve is very time consuming Help tools are useful for BASINS, but SWAT and HSPF lack good users manual
