Zusammenfassung:Making full use of functional variations with variable domain for handling boththe free surface and unknown part of the dam wall,a family of variational principles(VPs)forthe hybrid(direct-inverse)problem of free surface spillway flow under gravity is formulated interms of the potential function Φ.This theory offers new rational and versatile ways for dam de-sign and a sound theoretical basis for numerical solution,e.g.by the finite element method(FEM).
