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.

The State of Texas has about 367 miles of open Gulf shoreline, most of it typified by rather broad, sandy beaches and a comparatively mild climate that permits almost year-round use of this recreational resource. All but about 87 miles of the Gulf beach is accessible to the general public.

Aquifers in the Houston-Galveston area are composed principally of fluvial-deltaic sediments. The Alta Loma Sand is a complexly faulted, high-sand-percent unit that represents a seaward progression of fluvial, delta-plain, and delta-front facies.

Reservoir quality of lower Teritary sandstone reservoirs along the Texas Gulf Coast is controlled by sandstone depositional environment, mineralogical composition, and consolidation history (compaction, cementation, and leaching).

The Texas Coastal Zone is marked by diversity in geography, resources, climate, and industry.

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.

The Bureau of Economic Geology has been conducting regional studies of the Frio Formation along the Texas Gulf Coast to evaluate potential geothermal energy from deep, geopressured sandstone reservoirs (Bebout, Dorfman, and Agagu, 1975; Bebout, Agagu, and Dorfman, 1975).

Over 7,000 miles of lineations have been observed on aerial photographic mosaics of the Texas Coastal Zone. These lineations, in part, represent the surface traces of faults originating in the Tertiary sediments and propagating through the Quaternary sediments.

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.
