| dc.description.abstract | 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 detennine the effectiveness of existing design guidance for erosion and flood control in small watersheds. The monitoring program includes 11 technical areas: stream gauging, data collection and data management, hydraulic perfonnance of structures, channel response, hydrology, upland watersheds, reservoir sedimentation, environmental aspects, bank stability, design tools, and technology transfer. This report includes detailed discussion of the eight technical areas that were investigated by the U.S. Anny Engineer Waterways Experiment Station during Fiscal Year 1993, i.e., all of these areas except upland watersheds, reservoir sedimentation, and environmental aspects. In the area of data collection and data management, installation of continuous stage gauge instrumentation at 33 sites and crest gauges at an additional 42 sites was completed and data collection initiated. The initial development of the engineering database on Intergraph workstations was completed and made available to the U.S. Anny Engineer District, Vicksburg, for testing. | en_US |
