Mouth of the Colorado River, Texas, Monitoring Program /

Abstract : This report provides an overview of the monitoring effort of the U.S. Army Corps of Engineers at the mouth of the Colorado River, Texas. The report includes background information and objectives of the study, which were as follows: (a) Evaluate the design and efficiency of the weir jetty and adjacent impoundment basin so that project maintenance requirements and costs can be more accurately established. (b) Develop and improve equations for computing long shore sediment transport in the vicinity of the Colorado River, Texas. (c) Determine which sediment transport equations work best in the surf zone. (d) Collect data to aid in efforts to improve future designs of similar Corps projects. The report also includes data collection plans and procedures, data analysis, an evaluation of the project, and conclusions and recommendations. The data collection effort was divided into three main components: deployment of offshore directional wave sensors to obtain long-term, continuous wave, current, and water level information; intense, short-term field experiments that principally collected sediment transport data in the surge zone; and bathymetry surveys of the adjacent shorelines.
