The flow of water in two hydropower reservoirs in Costa Rica is calculated by a numerical model. The model uses a finite volume method to solve the Navier-Stokes equations for three dimensions on a general non orthogonal grid. The k-e t. Another three-dimensional finite volume method is used to calculate sediment concentration in the reservoirs by...


... The development of predictive tools, such as numerical sediment transport modelling, will be one important future aspect in the sustainable sediment management for the hydropower industry. Many studies have already calculated sediment transport and reservoir sedimentation in relation to flow [46,[74][75][76][77][78]. Zhang et al. [79], for example, have used a model for simulating non-uniform sediment transport in a German reservoir. ...
