Determining The Performance Of Breakwaters During High Energy Events: A Case Study Of The Holly Beach Breakwater System, Andrew Keane Woodroof
LSU Master's Theses
Breakwaters have been constructed in many areas along Louisiana’s coastline to protect the shoreline from wave energy and erosion. During normal conditions, these breakwaters can typically be analyzed using traditional empirical methods for emergent breakwaters. However, Louisiana’s coastline is under constant threat from tropical storms and hurricanes, during which breakwaters can frequently become overtopped or submerged systems. Recent studies show that the type of shoreline response to a breakwater system may vary depending on the crest height of the breakwater in relation to the mean water level. Though emergent breakwaters typically induce sediment accretion along the shoreline, studies using laboratory …

Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux
LSU Master's Theses
South Louisiana is vanishing. Subsidence due to relative sea level rise with erosion of weak wetland soils together produce devastating rates of land loss for this area. It is believed that high rates of erosion are due to weak strength properties of fine-grained sediments in the beaches, marshes, and other wetlands in coastal Louisiana. Wave action is known to initiate the movement of weak coastal soils in a manner that is related to the difference between the shear stresses applied by waves and the critical shear strength of erosional sediments. Direct shear tests were performed on samples obtained from the …
