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

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

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

van Woerkom, P.T.L.M. (author), Guelman, M. (author)Four well-known formalisms for mathematical modelling of the dynamics of a spacecraft/manipulator system are derived from the unifying d'Alembert principle. The Newton-Euler formalism is discussed in more detail, as it allows efficient numerical simulation. An algorithm is defined for the control of the manipulator end-effector motion in...report 1987

van Woerkom, P.T.L.M. (author)For the simulation of rigid spacecraft manipulator dynamics there exists efficient recursive software. Extension of this software for the simulation of flexible spacecraft-manipulator dynamics would have important advantages. In this paper the method of Equivalent Flexibility Modelling (EFM) is outlined. Each flexible body is re-modelled as a...report 1989

Steinbuch, M. (author)The application of wind energy conversion systems for the production of electrical energy requires a cheap and reliable operation. Especially at high wind velocities fluctuations from the wind field result in large mechanical loads of the wind turbine. Also fluctuations in the grid voltage may yield large dynamic excitations. In order to realize...doctoral thesis 1989

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

De Vries, M. (author)In Chapter 2 of this report an overview is given on fluvial processes involved in the modelling discussed. Chapter 3 is concerned with scale models, whilst Chapter 4 deals with numerical models. The main problems treated are, firstly, modelling of the water movement, followed by sediment transport and morphology. Attention is also given to the...report 1993
