Cost-effective numerical modeling for evaluation of overtopping protection systems
MetadataShow full item record
Case studies that focus on exceedance of the design flood event and the resulting overtopping conditions may be used to provide cost-effective analysis of overtopping protection systems. For this case study, conditions of levee overtopping are evaluated for the Probable Maximum Flood (PMF), with a two dimensional flow model (FLO-2D) used to represent the flood event in a relatively flat area susceptible to flash flooding. The model calculates the duration of overtopping and the resulting flood depths and velocities. The model outputs are utilized to evaluate the effectiveness of riprap as potential ...
