Geologic Framework and Depositional History of the Southeastern Texas Coast

Abstract:

Effective management of coastal resources and accurate prediction of future land losses are impeded by the lack of geologic framework investigations that link coastal processes with depositional systems and sea-level histories. This study demonstrates that predevelopment shoreline movement and wetland changes of the southeastern Texas coast were reasonably consistent and predictable because they were primarily controlled by the geologic framework. However, post-development human activities have caused large-magnitude imbalances in the natural forces. As a consequence of this induced disequilibrium, future predictions of coastal change will be more difficult to make and will require better quantification of human alterations.
