The understanding of the mechanisms underlying the diffusion, advection, and mixing of pollutants constitutes a crucial aspect in monitoring water resources quality, particularly in the context of river systems. The longitudinal dispersion coefficien

Local scour at the bridge piers is one of the most important factors threatening the stability of the bridges constructed on the rivers. This issue is mainly due to wake and horse shoe vortices. One of the key factors which intensify the local scour

Due to momentum exchange between main channel and floodplains, the flow hydraulics in compound channels is taken into account as a comparatively complicated system. Most studies in this research fields are focused on prediction of the cross-sectional
