AB: Extreme floods represent an increased risk for urban areas and agriculture. Time to time the protective earth dams are destroyed by a suddenly increased amount of water with destroing or even cathastrophic consequences. A numerical study of the soil moisture development within the earth body during the flood is simulated under a selection of boundary conditions. Several soil materials are considered. Simulations are performed firstly for homogeneous materials using the 2D single domain approach, in the second step the dual permeability simulations are done assuming inhomogeneities in the construction which may lead to the preferential flow. Results for saturated as well as for unsaturated part of the dam are analyzed. Using the appropriate simulation model may help to design safer flood dams and evaluate the reason of possible failures to prevent future disasters. The research has been performed in the frame of research project VZ 04 CEZ MSM 6840770005.
