Abstract

In the southeast Texas coastal plain, avulsions were studied on the lower Brazos, Navasota, Trinity, Neches and Sabine rivers using a combination of aerial imagery, digital elevation models and field surveys. Avulsions have important influences on the surface morphology and contemporary processes in all 5 rivers. Features associated with avulsions are active and distinct throughout the study area, and all the rivers have experienced geologically (if not historically) recent avulsions. However, no two of the study rivers have the same contemporary avulsion regime. First-orde differences in avulsion style are controlled by the stage of valley filling, and within the 3 ivers characterized by an unfilled incised valley, antecedent morphology associated with late Quaternary and Holocene coastal and fluvial-deltaic processes accounts for the major differences. Results show that even within a region of similar environmental controls and geological history local variations in inherited morphology can result in different avulsion regimes
