Deze notitie beschrijft de resultaten van een inleidend onderzoek naar de mechanismen van de erosie van de basislaag onder geometrisch open filters. Hierbij wordt in eerste instantie uitgegaan van de beter onderzochte erosie van de bodem van een waterloop zonder beschermende filterlaag. Op basis van metingen van Van Os (1998) in een inleidend...

In opdracht van Rijkswaterstaat directie IJsselmeergebied voert Rijkswaterstaat Dienst Weg- en Waterbouwkunde een beheer- en monitoringprogramma uit voor een tijdelijk baggerproevendepot in het Ketelmeer. Hierbij worden metingen uitgevoerd ten behoeve van correct beheer en monitoring conform de vergunningen. Ook worden er metingen verricht om...

In dit rapport wordt een drie-dimensionaal numeriek-wiskundig model ter berekening van het transport van zwevende en opgeloste stoffen in de Nederlandse kustwateren beschreven. Het belang van de modellering van zwevend stof en slib in drie dimensies wordt uiteengezet. Het model is een belangrijke schakel in een meer omvattende...

This literature review is part of the ongoing research on sand transport in oscillatory sheet-flow, as taking place at the coast during storms. Because sheet-flow corresponds to conditions of high shear stress, large amounts of sand are transported. Therefore it is an important part of the total sand transport (sheet-flow and suspended load)....

Data analysis of Delta flume observations and calculationsThe objective of the present study is to analyse the measurement data of profiles and velocity moments, to derive the measured cross-shore sediment transport rates from the profile records and to compare the observed transport rates with the results from several existing prediction models...

In the last decade, several mathematical models for cross-shore sediment transport have been developed under the assumption that the instantaneous sediment transport is directly related to the instantaneous horizontal velocity just above the boundary layer. Although some models took beach slopes into account, most of the calibrated data were...

Results of sediment transport calculations are often necessary in solving practical coastal engineering problems. (Sediment transport due to waves and currents). Many transport formulae have been proposed in literature in the past. Selection of the proper one while solving a particular problem, is a difficult task for a coastal engineer. In...

This report describes the development of a self-contained system for making long-term field measurements of bed elevation changes and the associated near-bed hydrodynamics and cohesive sedimentary parameters in estuarine environments. These measurements are required to ensure the understanding of these parameters and their interaction with bed...

Derivations and analyses of basic equations for I-dimensional sediment-laden flow (concentrations up to about 10% of volume) on a mobile bed are presented . Equations of mass and momentum conservation have been derived by means of a control section as well as by depth integration. Therefore a three-layer approach has been used (i.e., bed layer,...

An entrainment model for fluid mud is derived by integrating the equation for turbulent kinetic energy across the mixed layer and introducing some modelling assumptions. The resulting entrainment model is similar to models of mixed-layer deepening in lakes and reservoirs, but in addition accounts for the work needed to entrain bed material. Two...

In this chapter we consider beach profile and cross-shore sediment transport processes commonly encountered in coastal engineering applications. Main emphasis is on beach profile change produced by direct wave action, and our assumption will be that longshore transport processes are constant along the profile. Present engineering knowledge of...

Bed-levelling experiments are conducted in a straight laboratory channel. The experiments involve a significant fraction of suspended sediment transport. The purpose of the experiments is to provide data for modelling of the direction of sediment transport on a transverse sloping alluvial river bed, specifically in presence of suspended sediment...
