Shoreline Erosion Study Pleasure Island, Texas

摘要

This report summarizes the results of a study of processes affecting Pleasure Island, Texas, an 18-mile-long island separating Sabine Lake from the Sabine-Neches Waterway at Port Arthur, Texas. Wave, current, and meteorological data collected during the summer of 1982 and the winter of 1982-83 were analyzed to assess the relative contributions of man-made and natural processes contributing to Pleasure Island shoreline erosion. A summary of processes affecting erosion is presented, as are wave height distribution tables. Ship wakes were found to be the primary long-term cause of the continuing erosion of unstable bank material, although extreme natural events may also play a role.
