Popis: | The U.S. Army Corps of Engineers, Huntington District (COE or the District) is currently developing a feasibility level investigation to determine viable alternatives for local flood protection for the town of Milton and vicinity in Cabell County, West Virginia. The principal flooding source is the Lower Mud River. In the current investigations several alternatives are being evaluated to determine the most cost effective project. These alternatives consist of a levee (with varying levels of protection) and channel widening/channel diversion as well as combinations of these options. A detailed stable channel and sediment transport analysis for the project was warranted to determine the aggradation/degradation tendencies that may have adverse impacts on the operational and functionality characteristics of the local protection project. The objectives of this study were to define both the long-term and short-term aggradation/ degradation tendencies associated with the project. This information would be used as a basis for determining expected channel maintenance. Part of the scope for this study was to perform initial design of the new channel such that, on average, it would neither aggrade nor degrade over time. Design of the new channel using an innovative combination of geomorphic and sediment transport analyses is described in the paper. |
