For an overtopped rock-fill dam, the flow field consists of open flow and seepage flow, which have different properties. The overflow is characterized as variable flow and the seepage flow is not the Darcy flow, but non-Darcy flow. For the analysis of the flow characters, using the energy theory and the FEM, the author presents a method to calculate the combined flow (i. e. flow over and through a dam ) in this paper. The experimental work shows that, the calculated results agree well with the experimental ones.Therefore, it is not only possible, but also feasible to solve this problem with the presented method.
