Description :
The goal of this paper is to analyze the recent avulsion history of the San Antonio River Delta (SARD), Texas, with respect to avulsion type and frequency, the relative importance of various setup and trigger factors, and the maintenance of a multi-channel planform. A combination of fieldwork, geographic information system (GIS) analysis, and historical information are used to identify active, semi-active, and paleochannnels and the sequence of shifting flow paths through the delta. The role of deposition patterns and antecedent morphology, large woody debris jams, and tectonic influences were given special attention.
