Physical and numerical modeling for the investigation of downstream scour caused by sudden blockage in circular and box culvert inlets [PDF]
Journal of Applied Research in Water and WastewaterThis paper presents a comprehensive experimental and numerical study using non-cohesive uniform sand (d50 = 2 mm). The study investigates the impact of local scour downstream of four model culverts with different barrel shapes and inlet blockage sizes ...
