| Description: | Technical Report 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 determine 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 performance 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. Army Engineer Waterways Experiment Station during Fiscal Year 1994, 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. Army Engineer District, Vicksburg, for testing. In the area of hydraulic performance of structures, a model study to determine the feasibility of a low-drop structure using a 10-ft drop was conducted. Selected high- and low-drop structures were instrumented with stage gauges. The stage data will be used in calculating discharge coefficients for rating curves. In the area of channel response, the ftrSt detailed topographic survey of the 20 long-term sites was completed. The initial broad-based geomorphic studies of 1 watersheds and detailed geomorphic studies of 3 watersheds were completed. In the area of hydrology, development of HEC-1 hydrology models for 10 watersheds was initiated. The evaluation of the CASC2D hydrology model using the Goodwin Creek watershed was initiated. In the area of bank stability, a model study to determine the applicability of the bend way weir concept for bank stabilization was conducted. In the area of design tools, a riser pipe design system housed on the engineering database (Intergraph) was developed, tested, and made available for District use on the Coldwater River watershed. In the area of technology transfer, a video report on the DEC Project was completed, and a second video report on channel degradation processes was initiated. NOTE: This file is large.
