Rehabilitation of the South Jetty, Ocean City, Maryland
Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a littoral barrier to eliminate the shoaling problem and to repair the scour hold. Three headland breakwaters were constructed to stabilize Northern Assateague Island. The site was selected as part of the Monitoring Completed Coastal Projects (MCCP) Program to determine how well the rehabilitation project accomplished its design purpose. digital.library.unt.edu/ark:/67531/metadc304012/

Large-Scale Operations Management Test of Use of the White Amur for Control of Problem Aquatic Plants, Report 2: First Year Poststocking Results, Volume 2: The Fish, Mammals, and Waterfowl of Lake Conway, Florida
Abstract: "Fish, waterfowl and wading birds, and aquatic mammal populations on Lake Conway were surveyed for 1 year after the introduction of the herbivorous fish, white amur (Ctenopharyngodon idella). Low water levels reduced littoral zone area, which lead to stunted panfish and poorer condition of largemouth bass. Vegetated samples supported more diverse fish populations than beach sites. White amur and migratory waterfowl consumed the same plant foods; continued reduction of submerged plants by white amur may adversely affect overwintering waterfowl populations. Aquatic mammals were influenced by removal of vegetation due to shoreline development." digital.library.unt.edu/ark:/67531/metadc304022/
