The flow entrainment experiments are crucial for development of the localized scour numerical model, and they will complete the simplified scour prediction methodology for cases where scour appears to be caused by tidal flows without the complicating influence of waves. This web-based application calculates the flow net for a specified structure geometry that causes flow constriction and jet formation as shown in the examples below. The nondimensional flow net consists of streamlines and lines along which the discharge per unit width is constant. The nondimensional flow net consists of streamlines and lines along which the discharge per unit width is constant. A simple formula for estimating the maximum mean velocity at each location on the inlet channel cross-section.
Input parameters are the mean sediment grain-size and water depth at maximum flow.
