2010 Annual Report 1a.Objectives (from AD-416) The objective is to identify cost effective solutions for protecting levees of commercial aquaculture ponds and irrigation reservoirs from accelerated erosion by surface wave action in highly erodible soils of the Arkansas-Mississippi Delta. 1b.Approach (from AD-416) ARS will utilize the hydraulic laboratory facilities of the ARS National Sedimentation Laboratory to construct a physical model of typical levees and conduct tests to research and document the effectiveness of various mechanical treatment alternatives that serve to dissipate wind-wave energy and are cost effective. The data from these tests will be analyzed and compared to the extent possible with performance data from field tests planned by scientists from the University of Arkansas at Pine Bluff. 3.Progress Report This agreement has expired, and no further work has been performed. Progress concluded with the 2008 Annual Report, but was not terminated because of financial management reasons. See 2008 Annual Report for last reported progress.
