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

The State-owned submerged lands of Texas encompass almost 6,000 mi2 (15,540 km2). They lie below waters of the bay-estuary-lagoon system and the Gulf of Mexico and extend 10.3 mi (16.6 km) seaward from the Gulf shoreline (fig. 1).

Land and water resources have been analyzed in the Corpus Christi area--Aransas, Nueces, Refugio, and San Patricio Counties along the central Texas coast. The city and port of Corpus Christi compose the largest metropolitan center in the area.

Land resource units that are defined by their physical properties can be characterized quantitatively using engineering test data. Information about substrate properties in quantitative terms confirms and augments qualitative statements about the physical characteristics of land resource units.

Ground-water resources in the Corpus Christi area-Nueces, San Patricio, Refugio, and Aransas Counties (fig. 1)-were investigated as part of a broader study of land and water resources of the four-county area (Kier and others, 1974a and 1974b; Kier and White, in preparation).

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

This report is a compilation of all available data on mineral resources (exclusive of oil and gas) in 39 south Texas counties. Information from published and unpublished sources was checked and supplemented by field investigations.
