Scope and Nature of Shoreline Erosion Problems at Corps of Engineers ReservoirProjects: A Preliminary Assessment

摘要

Reservoir shoreline erosion has long been recognized as a problem at many Corpsof Engineers (CE) projects; however, there has been no formal action to quantify the scope of this problem or to summarize the type and cost of damage created by reservoir erosion. The US Army Engineer Waterways Experiment Station (WES) has assisted several CE Districts with shoreline erosion problems under the Water Operations Technical Support Program. By January 1990, the number of erosion problems known to WES personnel was large enough to suggest a need for assessment of the magnitude and impacts of reservoir shoreline erosion nationwide. Accordingly, WES queried GE Districts to determine if shoreline erosion may be a ubiquitous problem, and to obtain a general idea of the damage being caused. This information on the general extent of the problem is necessary to determine the cost effectiveness of conducting a more comprehensive analysis of existing or potential erosion damage at each affected project. This report provides the findings from the query of CE Districts.
