Applying indicators of hydrologic alteration to Texas streams: overview of methods with examples from the Trinity River basin
Richard L. Kiesling
2003, Fact Sheet 128-03
Streamflow is a component of aquatic ecosystem health, and long-term alteration of streamflow characteristics can produce large changes in aquatic ecosystem structure and function. The physical, chemical, and biological properties of aquatic ecosystems are all affected by the magnitude and frequency of streamflow. For example, the physical structure (hydrogeomorphology) of...
