Hydrodynamic characteristics of submerged vegetation flow with non-constant vertical porosity. [PDF]
PLoS ONE, 2017 In order to investigate the influence of the vertical variation of porosity on open-channel flow with submerged vegetation, vertical non-homogeneous stumps and stems in submerged vegetation flow are simulated with truncated cones in a laboratory flume ...

Flow Characteristics in Vertical Shaft Spillway with Varied Inlet Shapes and Submergence States
Tikrit Journal of Engineering SciencesA spillway is an essential hydraulic structure that discharges excessive water, especially during floods from upstream to downstream of the dam. A shaft spillway is sometimes used when a limited area is available. This study used four physical models of
