Ecological Model - Edwards Aquifer Authority

Ecological Model

The Ecological Model is comprised of four major submodels, which address river hydraulics, water quality, submerged aquatic vegetation, and the fountain darter population.  The model is used as a management tool to examine the effects of alternative flow regimes and submerged aquatic vegetation assemblages on fountain darter populations.  The conceptual overview is shown below.

The model was developed collaboratively by:

  • Dr. William Grant (Texas A&M University)
  • Dr. Todd Swannack (U.S. Army Engineer Research and Development Center)
  • Dr. Hsiao-Hsuan (Rose) Wang (Texas A&M University)
  • Dr. Thom Hardy (Watershed Systems Group)
  • Dr. George Ward (University of Texas Austin)
  • Dr. Robert Doyle (Baylor University)
  • Dr. Timothy Bonner (Texas State University)
  • Mr. Ed Oborny (BIO-WEST, Inc.)
