Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1991-01-01 Abstract Some information is given how to use the scour model DUCT-SUSTRA (Hoffmans, 1991). The scour model predicts the morphological process in scour holes or trenches and consists of two separated sub-models: a flow model DUCT and a morphological model SUSTRA. The flow model is based on the equation of continuity and the momentum equations for turbulent flow (Vreugdenhil, 1982). The Reynolds-closure problem is solved by prescribing the eddy viscosity with model equations (Hoffmans, 1991). The concentrations are calculated by the morphological model, which is based on the convection-diffusion equation (van Rijn and Meijer, 1986). The bed load transport and the concentration at the reference level are calculated with stochastic equations. The software of the scour model is written in FORTRAN and can be installed on a personal computer. However, it is recommended to install it on a larger computer, if a grid of more than 100 nodes is desired. The models DUCT and SUSTRA are coupled by the sub-models SMOOTH, GENBLK and SUSTDUCT, figure 1. In section 2. the structure of input and plot files concerning DUCT is specified. In the subsequent sections the procedure is explained how to make a run with DUCT-SUSTRA. It is remarked that this 'manual' is still incomplete.
