Abstract

The one-dimensional model provides useful insight inm impacts of regulatory design parameters of longitudinal
training dams. Preliminary conclusions include:
1. Adjusting the inlet weir height could influence the discharge distribution towards the side channel between 1% (fully closed but porous inlet) to 30% (fully open and porous inlet).
2. Smaller side channel width (e.g. sedimentation of the side channel) will result in significant reduction of discharge distribution toward the side channel.
3. The porous discharge through the inlet and openings is negligible compared to the weir discharge.
