The results of laboratory experimental testing and computer simulations of dambreak with the SPH method are presented in the paper. Smoothed particle hydrodynamics is a meshless particle method for simulation of fluid flows. TheTisIsat model, developed at the Faculty of civil and geodetic engineering, Chair of fluid mechanics with laboratory, was used. The results of the TisIsat model showed good agreement with measurements.

COBISS.SI-ID: 5532769Dams that were built to accumulate water for energy production, agriculture, water supply and other purposes are among most important and sophisticated engineering structures. Despite obeying high standards during their design andconstruction they represent a certain threat to villages and inhabitants living downstream. A state of the art review of dam-break wave and debris flowcomputations in Slovenia are given in the article. Among others three practical case studies are shown more into detail: simulation of dam-break waves in the chain of hydro power plants on the lower Sava River where also the nuclear power plant Krško is situated, a wave resulting from a potential dam-break of the upper storage reservoir of the planned pumping power plant Kozjak in NE Slovenia and computations of landslide initiated debris flow in Log pod Mangartom, NW Slovenia.

COBISS.SI-ID: 6077793Smoothed particle hydrodynamics (SPH) is a relatively new meshless Lagrangian particle method. Modelling with SPH is still under development and not thoroughly tested. The main advantage of SPH is the possibility of simulating the phenomena at the rapidly changing free surface, depth oscillations, breaking waves, etc. We used the SPH method to simulate water oscillations in an accumulation that was caused by a dam failure. Large natural disasters can be caused by dam break waves. For exact simulations of downstream events, depth oscillations in accumulation must be known in full detail. This paper presents simulation results of depth oscillations in accumulation using the SPH method.
