Evaluation Of Beach Nourishment Evolution Models Using Data From Two South Carolina Beaches: Folly Beach And Hunting Island, Sc, Usa, Harry Weathers, George Voulgaris

Beach nourishment is a common method used for mitigating coastal erosion. However, it is also a costly undertaking and requires an appropriate cost-to-benefit analysis. Although the costs can be estimated relatively easily, the benefits are directly related to the life expectancy of the proposed project. With this in mind, three existing beach replenishment time-evolution models (the Linear Erosion, the Verhagen, and the One-Line models) were compared for their ability to represent data from two beach nourishment projects that have taken place in South Carolina, USA, at Folly Beach and Hunting Island. Another newly introduced model that combines the One-Line model …

This research is a combination of three studies carried out to explore weather impacts on traffic parameters. The first part investigates light rainfall’s impact on uncongested speed during the daytime on a two lane state highway with a detailed statistical analysis and spatially compatible rainfall and speed data. The results show that the speed distribution in light rain conditions is significantly different from the no-rain condition. Light rain causes a drop of 0.9 mph (1.5 km/hr) or 1.8% of speed from the no-rain condition. Variability of speed is not found significantly different between the two conditions. The second part investigates …
