Scour protections with ripraps are porous which allows turbulent flow penetration.One of the consequences of the penetrating turbulent flow is the possible erosion of fine particles blow the scour protection.

In the last decade 1D, 2D and 3D numerical models have been extensively used to simulate river-floodplain hydraulics and sediment deposition processes in floodplains.
Outburst floods are characterised by being sudden,short-lived and containing high energy. Such kinds of outburst floods generally comprise an intense advancing water wave which can induce considerable
For boundary-layer resolving models, a suitable boundary condition is needed for suspended sediment.For most of empirical formulas, the equilibrium concentration is specified at certain reference heig
The focus of this study is to describe radionuclide pollution transport in the surface water using a box model with lagging argument (UNDBE).It is hypothesized that this model will increase the accura
Flow passing through channel bends is three-dimensional.Some three-dimensional models have been developed to simulate this flow phenomenon.
The purpose of this project is to create a CFD program that can simulate Heat flow in a fluid volume.This is to overall optimize energy consumption in a control volume while regulating temperature.
Based on the excess shear stress principle, a finite element model that simulates the temporal and spatial changes in the profile of cohesive riverbanks is developed.
Based on RNG κ-ε model, VOF model and dynamic mesh model, the hydraulic characteristics of the Ogee curve section of spillway tunnel are simulated successfully in upstream radial gate closing process
Sediment transport and its consequent morphodynamic evolution in bay systems are complex physical processes.A DELFT3D numerical model is adopted in simulating the long-term geomorphological processes
The objective of the present paper is to investigate in detail the changes in the hydro-morpho-sedimentary processes occurring in confluence zone using a numerical model.
