Booij, N. (author)FLOWS is a recently developed ICES subsystem for applications in the field of hydraulic engineering. It is able to compute steady as well as unsteady flows in hydraulic networks of given dimensions. This means that is does not optimize any parameters describing the network. The network may be composed of open and closed channels, reservoirs and...report 1980

Booij, R. (author)In this investigation the reproduction of tidal flow in channels of estuaries by means of several simple mathematical models is considered. Attention is mainly paid to velocity and shear stress profiles and to hysteresis effects of the shear stresses with respect to the surface velocity. Only one-dimensional models obtained by neglect of...report 1981

Booij, N. (author)A mathematical model for the combined refraction-diffraction of linear periodic gravity waves on water is developed, in which the influence of inhomogeneities of depth and current is taken into account. The model is used to compute partial reflection of waves a gully or an undersea slope, with influence of a current. The model is also applied to...doctoral thesis 1981

Booij, R. (author)For the prediction of dispersion phenomena and of changes in the morphology of an alluvial bottom, a detailed description of the water flow is necessary. The flow in estuaries is a complicated one, partly because of the time-dependence. To isolate this aspect of tidal flow a simplifying one-dimensional (vertical) flow model 1S used. This one...report 1982

Booij, R. (author), Pennekamp, J.G.C. (author)Knowledge of the secondary flow is essential for predictions about the morphology of alluvial bottoms in tidal channels. In this research the determination of the secondary flow is based on a known depth averaged velocity field. The depth averaged velocities must be computed with a high accuracy in order to make possible a reasonable...report 1983

Pennekamp, J.G.S. (author), Booij, R. (author)In order to make predictions for the morphology of an alluvial bottom a thorough knowledge of the flow pattern is needed. In tidal channels, without a nett discharge over the tidal period, the main flow effects on the morphology will, on an average, remain relatively small because of the tidal variation. Therefore second order flow phenomena...report 1983

Holthuijsen, L.H. (author), Booij, N. (author)Formulate a numerical wave hindcast model which can be used to obtain realistic estimates of wave conditions in the Oosterschelde as input to a numerical geomorphological model. A directionally decoupled, parametric wave hindeast model is recommended that includes parameterized versions of conventional bottom- and current refraction, some degree...report 1983

Pennekamp, J.G.S. (author), Booij, R. (author)For the computation of depth averaged flows in tidal channels and rivers a recently developed fully implicit finite difference method of the ADI-type proved vastly superior to the partly explicit variants, commonly used. The fully implicit variant allowed a relatively large time step in combination with arealistic lateral diffusion coefficient....report 1984

Booij, R. (author), Pennekamp, J.G.C. (author)Prediction of bottom changes in rivers and tidal channels require a thorough knowledge of the secondary flow, as this flow gives rise to bottom slopes transverse to the main flow direction. In the model used in this research, the computation of the secondary flow field is based upon an, independently computed, depth averaged main flow field. In...report 1984

Booij, R. (author), Yu, X.Q. (author)De sedimentatie in een haven wordt o.a. bepaald door de wateruitwisselingen door de havenmond en de stromingspatronen in de haven. Dit onderzoek beperkt zich in hoofdzaak tot het geval van door entrainment (meeslepen) van water uit het havenbekken in de menglaag tussen de rivier en het havenbekken veroorzaakte uitwisseling. Afgezien wordt van...report 1986
