Shorelines bordering the bays of Texas are generally not as dynamic as those along the Gulf of Mexico. Nevertheless, the predominantly erosional movement of these bay shorelines translates to large losses of wetlands, arable uplands, and recreational and residential property.

Changes in the position and stability of shorelines in the San Antonio Bay system (San Antonio, Espiritu Santo, and Mesquite Bays), Texas Gulf Coast, were documented using historical monitoring techniques.
