The purpose of monitoring the Demonstration Erosion Control (DEC) project is to evaluate and document watershed response to the implemented DEC project. Documentation of watershed responses to DEC Project features will allow the participating agencies a unique opportunity to determine the effectiveness of existing design guidance for erosion and flood control in small watersheds. The monitoring program includes 11 technical areas: stream gaging, data collection and data management, hydraulic performance of structures, channel response, hydrology, upland watersheds, reservoir sedimentation, environmental aspects, bank stability, design tools, and technology transfer. A 1:12-scale physical model was used to investigate a proposed sheet-pile grade control structure for the DEC Project in the Yazoo Basin, Mississippi. Low-drop grade control structures have been used as a means to arrest erosion in incising channels. Existing design criteria for these sheet-pile drop structures have been based on a maximum drop of 6 ft. The objective of this study was to determine the feasibility of using a 10-ft drop and develop design guidance pertaining to the higher drop. A drop structure design based on a study conducted by Colorado State University (CSU) was adopted for the 10-ft drop.
