Result comparison of simulations of design discharges using energy loss equation and dynamic wave aproximation

Abstract

The flood risk is still a very serious problem, especially in urban areas. Man’s knowledge in the fields of hydrology, water management and also information and geoinformation technologies develops very quickly, so there are many techniques of the flood risk assessment. Ones of the most effective and actual tools of the hydrological practice are hydrological models. Nowadays, there is a large number of these models and the most advanced ones offer a number of several computation hydrological techniques. The aim of this contribution is to compare the results of the design flood waves moving through a river computed using two different hydrological techniques, the energy loss equation and dynamic wave approximation.
