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.

The Lower Cretaceous Hosston and Hensel Sandstones are important sources of ground water in North-Central Texas. Delineation of major depositional systems and their component facies within these formations provides a method for predicting the quantity, movement, and chemical composition of water in the aquifers.

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.

Change, both natural and man-induced, is a significant and defining element of the Coastal Zone. Man-induced change, by definition, can be controlled if desired. The work of nature, however, is altered and modified with much more difficulty, if at all, and attempts to do so commonly lead to unintended results.
