  • Description:
    An environmental study was conducted at Sargent Beach, Texas, an erosive beach bordering the Gulf of Mexico. The objectives of this study were to determine the characteristics of the beach, the magnitudes of changes which have occurred at Sargent Beach, and to analyze possible factors which may be controlling the observed beach changes. Results show the beach has eroded at an increasing rate since at least 1930 with recent shoreline retreat rates averaging 30 feet per year. Storms are the primary agents that remove material from the beach, while lost sediments are not replaced because Brazos River sands normally expected to move alongshore are trapped in the Brazos delta. Hurricanes may free stored deltaic sands carrying major quantities offshore from beach areas. Beach erosion is further aggravated by decreased sand input to the coast from the Brazos River due to alterations to the river and its drainage basin in the 1940's.
