Hoffmans, G.J.C.M. (author)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...report 1991

Hoffmans, G.J.C.M. (author)The general purpose of this research project is to model mathematically the local scour downstream of a structure (2-D). The model has to simulate the development of the scour as a function of the time. Basically two models are necessary namely a flow model and a morphological model. The latter model has to describe the bed and suspended load...report 1988

Olthof, J. (author), Verhagen, H.J. (author)As a continuation of the initial study on the morphology of the Douro mouth, performed by Hydronamic in 1982, the Administracao dos Portos do Douro e Leixoes commisioned Hydronamic bv to construct a mathematical hydro-morphological model of the Douro mouth. This second part of the morphological study of the Douro mouth is divided into three...report 1984

Verhagen, H.J. (author)Hydronamic has performed a study for the design of the new access channel to the terminal of Siderurgia Nacional at Seixal (near Lisbon) in the Tagus estuary. The report deals with the following subjects: - In chapter 2 a description is given of the mathematical tidal model, the calibration thereof and the final results. - Chapter 3 deals with...report 1982
