Effects of subaqueous debris accumulations on local scour around the pier and riverbed morphology Open
During the flood, debris tends to accumulate around the pier in the channel. The depth of debris accumulation beneath the water surface significantly influences on local scouring around the pier, and affecting its flood-fighting capacity. …

Numerical simulation of morphological evolution in a gravel-bed meandering river during floods: a case study on the Sai-Jiang river Open
The water velocity undergoes a significant increase during the initial stage of floods. The present study focuses on investigating the scours and silting occurring in an S-shaped gravel-bed river. The primary objective is to analyze the im…

Effect of residual cofferdam at the diversion tunnel inlet on the index of river closure and the dumped materials: A Case study Open
The cofferdam built at the inlet of the diversion tunnel may be left due to incomplete blasting demolition, which affects the river closure. Several indexes have been used to evaluate the difficulty of river closure, but all indexes suffer…

Numerical Modeling of Coupled Surge‐Heave Sloshing in a Rectangular Tank with Baffles Open
Liquid sloshing under coupled surge and heave excitations in a rectangular tank has been numerically investigated by applying a Navier–Stokes solver. Fieriest coupled sloshing was further considered, and the internal baffle was expected to…

Case Study on Application of the Step with Non-Uniform Heights at the Bottom Using a Numerical and Experimental Model Open
Steps effectively dissipate the energy of water along a path and reduce the size of the stilling basin but are rarely used in curved spillways. The shore spillway of a reservoir, which is restricted by topography, must be arranged in a cur…

Free Surface Characteristics of Flow around Two Side-by-Side Circular Cylinders Open
The three-dimensional free surface characteristics of flow around two equal diameter cylinders in a side-by-side arrangement were studied numerically. The flow fields were simulated with a three-dimensional finite volume method based on th…
