Irregular waves propagating across upward sloping ramps: surface elevation and depth-averaged velocity simulated by SWASH model

This datasets contain the topography (.txt) and input files (.sws) and raw outputs (.mat) of SWASH model (version 4.01A) for the simulation of irregular waves propagating across upward sloping ramps. Two bottom slopes (1/40 and 1/80) and two spectral width incident waves (γ=20 and 3.3) are considered, yielding four runs of test. For each run of test, times series of water surface elevation and depth-averaged velocity are sampled at a spatial and temporal resolution of 0.5 m and 0.1 s, respectively. Total simulation time was 1 h 5 min, while the first 5 min was for warming-up and the data was not sampled. Note: The source code of SWASH model was compiled using gfortran. Using different compilers, e.g. ifort, could generate different surface elevation signals. The primary harmonics of the signals are statistically identical , but the second-order subharmonics could be evidently different.
