Numerical investigation on the role of check dams with bottom outlets in debris flow mobility by 2D SPH
TL;DR: In this paper , the authors investigated the interaction between a viscous debris flow and check dams with bottom outlets via flume tests using 2D smoothed particle hydrodynamics, and they showed that the energy breaking, flow regulation, and sediment trapping functions of a check dam operate well when the normalized height of the bottom outlet is in the range 0.15-0.6.
