Mass Residuals as a Criterion for Mesh Refinement in Continuous Galerkin Shallow Water Models
Publisher: American Society of Civil Engineers
Abstract: Mass balance error has been computed traditionally by using conventional fluxes derived from the conservation of mass equation, but recent literature supports a method based on fluxes that are consistent with the discretization ...
Effects of Model Resolution and Coverage on Storm-Driven Coastal Flooding Predictions
Publisher: ASCE
Abstract: Predictions of storm surge and flooding require models with higher resolution of coastal regions, to describe fine-scale bathymetric and topographic variations, natural and artificial channels, flow features, and barriers. ...
Sensitivity of Storm Surge Predictions to Atmospheric Forcing during Hurricane Isaac
Publisher: American Society of Civil Engineers
Abstract: Storm surge and overland flooding can be predicted with computational models at high levels of resolution. To improve efficiency in forecasting applications, surge models often use atmospheric forcing from parametric vortex ...
Simulating Hurricane Storm Surge in the Lower Mississippi River under Varying Flow Conditions
Publisher: American Society of Civil Engineers
Abstract: Hurricanes in southeastern Louisiana develop significant surges within the lower Mississippi River. Storms with strong sustained easterly winds push water into shallow Breton Sound, overtop the river’s east bank south of ...
