Abstract
Water is fundamental for life and development, attracting the permanence of communities in its surroundings. Use and handling of water resources was encouraged in order to maximize their benefits and possibilities, such as the installation of dams. However, several dangers, such as floods provoked by dams rupture and water pollution with its undesirable consequences, arise simultaneously becoming even more serious due to urbanization. For the development of studies related to disasters provoked by a dam rupture, it is necessary to know the water flow in these artificial barriers. A mathematical model using the shallow water equations applied to Santa Bárbara Dam, located in Pelotas City (in the southern region of Brazil) is proposed in this work. The numerical simulation of the model is performed by applying the finite element method (FEM) together with the characteristic-based split (CBS) method for space and time discretization, respectively.
