Kranenburg, C. (author)The Prandtl mixinglength model of turbulent exchange of mass and momentum is applied to calculate the entrainment of overlying water into a layer of suspended fine sediment at a horizontal bed. In the field the flow and turbulence in such a concentrated benthic suspension (CBS) are driven by a streamwise pressure gradient resulting from the...report 1999

Suastika, I.K. (author)In this report we present some results of a laboratory pilot study which has been conducted to test a method to artificially enhance the turbulence of a water flow in a laboratory flume. The purpose of this test is to provide data which will be used to verify whether the method is suitable for the study of the dissipative effects of turbulence...report 1998

Bijvelds, M.D.J.P. (author)In this report the water flow in harbours, that are situated on a river, are considered. Due to the flow velocity difference between the river and the harbour, a turbulent mixing layer develops at the harbour entrance. The shallowness of the water induces the coexistance of two disparate turbulent length scales in these regions. Besides the ...report 1997

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

Kranenburg, C. (author)A kmodel is formulated that consists of the turbulent kinetic energy equation and an algebraic expression for the mixing length taking into account the influence of stratification. Applicability of the model is restricted to shallow, nearly horizontal flows. For localequilibrium flows the model reduces to the wellknown mixinglength...report 1985

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 timedependence. To isolate this aspect of tidal flow a simplifying onedimensional (vertical) flow model 1S used. This one...report 1982

Koppel, T. (author)Experiments on unsteady separating flow past a sudden expansion in an open channel are described. To simulate tidal flow the flow rate in the approach channel varied as a halfsine with time. Different visualization techniques to obtain an insight into the behaviour of the separating vortex in time and space were used. LaserDoppler velocimetry ...report 1981

De Vriend, H.J. (author)After the study of fully developed and developing steady laminar flow in curved channels of shallow rectangular wet crosssection (see earlier reports in this series), steady turbulent flow in such channels is investigated as a next step towards a mathematical model of the flow in shallow river bends. A mathematical model is developed for this...report 1979

Hinze, J.O. (author)NOTE: REPORT IN GERMAN, ONLY THE ABSTRACT IS IN ENGLISH Memory effects in the flow of fluids are known long since. One has to reckon with such effects when studying the flow of nonNewtonian fluids, for instance when they exhibit a viscoelastic behaviour. Certain phenomena in turbulence also seem to point towards a viscoelastic behaviour. If,...report 1975
