Turbulent seepage in a 6-m rock-fill dam – field measurements, analytical & numerical Solutions
2006 (English)Conference paper (Refereed)
Field experiments of seepage, stability and dam break have been made in several embankment dams of various materials in North Norway. One of the dams is a homogenous rock-fill dam, 35 m long, 6.2 m high and 2.9 m wide on crest. Turbulent seepage occurs in the dam body. Assuming isotropic porous media, an analytical solution in two dimensions is developed of flow discharge and phreatic surface in turbulent seepage. Using the CFD code FLUENT, numerical simulations are made to find the best-fitted turbulent permeability. The analytical and numerical results are compared with data from the field measurements. To be able to correctly predict the turbulent seepage is important, an issue that affects calculations of slope stability, particle erosion and downstream reinforcement measures.
