Direct solution for discharge in circular free overfall
Journal of Hydrology, 2012Summary Free overfall at the end of a circular channel is simulated as sharp-crested weir with zero height to get end-depth-discharge relationship. A closed-form equation for discharge in terms of end depth for subcritical flows is proposed and verified with the experimental data.

Local scour due to free overfall jet
Proceedings of the Institution of Civil Engineers - Water Management, 2006A study was conducted to determine how the tailwater depth beneath a free-falling water jet affects the dimensions of local scour. Available data on scouring in uniform bed material due to circular and rectangular outflow jets were compiled and analysed. It was found that the scour hole geometry (i.e.

Numerical Simulation of 3D Free Overfall Flows
20123D Free overfall flows by the two-phase least-squares finite element method (LSFEM) have been presented. The dynamic and kinematic boundary conditions of free surface are described in an Eulerian coordinate system. The governing 3D Navier-Stokes equations in association with the color function are solved by element-by-element scheme. In this simulation,

FLOW MEASUREMENTS IN ROUGH FREE OVERFALL
2018In this paper, the relationbetween the brink and critical depth is studied experimentally andtheoretically to predicted theoretical discharge equation using in rough freeoverfall. Three different; bed rough materials, sizes and distributions wereused and tested experimentally to developed the discharge relationship.
