Texas Watershed Planning

Introduction to Watershed Modeling Course

October 5, 2017
9:00 am – 5:00 pm 

Texas Commission on Environmental Quality, Bldg. B Room 201A,
12100 Park 35 Circle
Austin, TX 78753 (map)

The workshop will provide watershed coordinators with an introduction to watershed modeling and cover models available for use. Participants will gain an understanding of what model is needed for watershed protection planning, how modeling fits into 9 Elements, and the resources needed to take the next steps. The models and tools the course will cover include: load duration curves (LDC), Spreadsheet Tool for Estimating Pollutant Load (STEP-L), Generalized Watershed Loading Function (GWLF), P8 urban catchment model (P8-UCM), Soil and Water Assessment Tool (SWAT), AGricultural Non-Point Source Pollution Model (AGNPS), Hydrologic Simulation Program - FORTRAN (HSPF), and Storm Water Management Model (SWMM).

Training topics include:

  • Purposes and limitations of different models
  • Timelines
  • Data needs (watershed characterization, water quality information)
  • Cost estimates
  • Literature values vs. monitoring
  • Quality Assurance Project Plans (QAPPs)
  • Presenting models to stakeholders

Draft Agenda

Cost: $100 includes materials and breaks. Payment is due at the time of registration. All participants will receive a certificate of completion at the end of the day.


Dr. R. Srinivasan, Ph.D., P.E., is a professor in the Departments of Ecosystem Sciences and Management and Biological and Agricultural Engineering at Texas A&M University. Dr. Srinivasan is one of the developers of Soil and Water Assessment Tool (SWAT) and travels around the world teaching SWAT workshops.

Dr. Larry Hauck, PE, Ph.D., is the lead scientist at Texas Institute of Applied Environmental Research (TIAER), managing the environmental sciences and economics program. Hauck's research interests include landscape loading of nutrients in agricultural watersheds, biological and chemical response of receiving waters to nutrient enrichment, connection of land management and agricultural practices to receiving water quality, and development and application of watershed loading models and hydrologic/water quality models. Hauck has also been involved in projects applying bacterial source tracking and the load duration curve method to the TMDL process. He is the project manager for several TMDL projects in Texas that involve nutrients, bacteria, and dissolved oxygen.

Dr. Lucas Gregory currently serves as a research scientist for the Texas Water Resources Institute. In this role, he develops effective and efficient projects and provides leadership for multiple watershed assessment, planning and implementation projects, focusing on water quality impairments in rural Texas water bodies.
