De Vriend, H.J. (author)The present lecture deals with models for situations in which the spatial dimensions cannot be separated according to the scales of the morphological processes. Rather common examples of such situations are the morphological evolution near structures (e.g, breakwaters), river outflows, tidal inlets, etc. But also in the absence of such distinct...report 1992

Kamphuis, J.W. (author)To solve coastal sediment transport and morphology problems, it is necessary to construct a hydrodynamics model to simulate the fluid flow. The hydrodynamics model is then used to calculate sediment transport rates and in turn, these sediment transport rates are used to determine morphology. The hydrodynamics model is based on the Equation of...report 1992

Chen, C.J. (author), Singh, K. (author)The use of second order closure turbulence model in predicting turbulent flows is known to be more successful than the classical mixing length model. However, it is found that if the turbulence constants are not altered or modified, the second order closure turbulence model is unable to predict satisfactorily f or some flows such as round jet...report 1985

Ten Brummelhuis, P.G.J. (author), De Jong, B. (author), Heemink, A.W. (author)This report gives an exposition of the applications Kalman filters and the related nonlinear filters offer when used in models describing tidal motion in seas and estuaries. In addition to methods that are generally used in this field, for example deterministic and black-box models, Kalman filters can provide significant contributions in...report 1985

Nakato, T. (author), Kennedy, J.F. (author), Vadnal, J.L. (author)The principal features of the numerical model developed herein for calculation of flow and sediment-transport distributions in alluvial-river bends may be summarized as follows: i. The secondary-flow strength and the bed topography are uncoupled from the calculation of distributions of lateral shift velocity and streamwise velocity. This is...report 1983

(author)ONLY SUMMARY IS IN ENGLISH; REST OF THE REPORT IS IN DUTCH ELNAG is a special purpose analog computer especially built for the simulation of unsteady flow in unconfined aquifers (e.g. seadikes). The analog model consists of a resistance-capacitance electrical network (5000 grid-points) which allows the permeability and the storage capacity of an...report 1979

Ostendorf, D.W. (author), Madsen, O.S. (author)Two momentum based longshore current models and a preliminary longshore sediment transport model are derived, calibrated and tested in the present investigation. The Linear Longshore Current Model predicts the relatively small longshore current induced by monochromatic, two dimensional, gravity waves of finite height and near normal incidence...report 1979
