Waller and Shoal Creek in the central area of Austin, Texas are two very good examples of how increased urbanization can lead to a disruptive watershed system.
Natural land is covered with impervious cover which can damage watershed systems.
Streets, buildings, sidewalks and parking lots are all examples of impervious cover. The environmental stability and condition of the creeks is primarily determined by those who live and work along each watershed. This project is an overview to problems such as flood damages, sediment deposits, mass wasting, erosion, and stream flow contamination for both Shoal and Waller Creek. We also evaluated a total of six stops along Shoal and Waller that have been affected by urbanization. Updated on 12 May 1998.
