Effectiveness of Silt Screens

A large series of numerical simulations with varying flow velocity, screen height, screen width, settling velocity of the sediment, water depth and upstream sediment concentration profile is conducted. The process of vertical diversion is investigated in a 3D modeling approach using large eddy simulation (LES). Performance of this numerical model is validated by means of laboratory experiments. The process of horizontal diversion is assessed with a two-dimensional horizontal (2DH) modelling approach.
