Reducing Uncertainty in Prediction of Dune Erosion during Extreme Conditions
Coastal dunes protect low lying coastal areas against the sea. Extreme waves and water levels during severe storms may cause breaching of the dunes. Consequently, serious damage due to flooding and direct wave attack could occur, resulting in loss of life and property. Proper coastal management implies that reinforcement measures will be taken if the actual safety level does not meet the agreed...
متن کاملEfficient simulations of long wave propagation and runup using a LBM approach on GPGPU hardware
We present an efficient implementation of the Lattice Boltzmann method (LBM) for the numerical simulation of the propagation of long ocean waves (e.g., tsunamis), based on the Nonlinear Shallow Water (NSW) wave equation. The LBM solution of NSW equations is fully nonlinear and it is assumed that the surface elevation is single-valued (hence, waves do not break or overturn). For the treatment of...
متن کاملThe role of bathymetry, wave obliquity and coastal curvature in dune erosion prediction
Low lying coastal areas have always been attractive for people to live, but are also prone to flooding. In The Netherlands, half of the population lives in the coastal area below mean sea level where two-thirds of the economic value is located. Coastal dunes protect the hinterland from flooding as a primary sea defence along the major part of the Dutch coastline. The envisaged protection level ...
متن کاملLimits of Wave Runup and Corresponding Beach-Profile Change from Large-Scale Laboratory Data
ROBERTS, T.M.; WANG, P., and KRAUS, N.C., 2010. Limits of wave runup and corresponding beach-profile change from large-scale laboratory data. Journal of Coastal Research, 26(1), 184–198. West Palm Beach (Florida), ISSN 07490208. The dataset from the SUPERTANK laboratory experiment was analyzed to examine wave runup and the corresponding upper limit of beach-profile change. Thirty SUPERTANK runs...
متن کاملDispersive wave runup on non-uniform shores
Historically the finite volume methods have been developed for the numerical integration of conservation laws. In this study we present some recent results on the application of such schemes to dispersive PDEs. Namely, we solve numerically a representative of Boussinesq type equations in view of important applications to the coastal hydrodynamics. Numerical results of the runup of a moderate wa...
