Analysis of the bed forms simulated using the three-dimensional model SSIIM, case of a natural shallow water channel

Abstract

This work's objective is to analyze the dominant dimensions of the simulated bed forms using a three-dimensional hydrodynamic model coupled with particle transport processes and useful numerical methodologies to estimate the changes in the morphology of free surface flows. In this sense, descriptive and spectral statistical techniques were applied to the simulated bed forms geometries, obtaining a spatial and temporal discretization of the dominant dimensions in the study domain of the Tercero river as it passed through the city of Villa María, Argentina. The characteristics of the selected domain correspond to that of a river with shallow waters and a bed slope corresponding to that of a plain channel.
