The purposes of this study were (1) to quantify recent (1974 to 1982) movement of Texas shorelines and vegetation lines by analysis of aerial photographs; (2) to place this movement in historical (pre-1974) context; and (3) to examine the influence of environmental variables such as storms, sea l

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.

Changes in shoreline position occurring for more than a century provide estimates of the relative stability of shorelines and, along the Texas coast, allow comparisons of shoreline changes before and after human modifications became significant.

On August 18, 1983, Hurricane Alicia crossed the upper Texas Gulf Coast and caused extensive property damage, especially along West Beach of Galveston Island.

Changes in the position and stability of shorelines around Corpus Christi, Oso, and Nueces Bays, Texas Gulf Coast, were documented using historical-monitoring techniques.

Historical monitoring along Mustang and north Padre Islands records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.

Historical monitoring along central Padre Island records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.

Historical monitoring along Matagorda Island and San Jose Island records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.

Historical monitoring along Matagorda Peninsula from Brown Cedar Cut to Pass Cavallo records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.

Historical monitoring along Brazos and south Padre Islands records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.
