Fine sediment dynamics in a shallow lake and implication for design of hydraulic works

Lake Markermeer is a large (680 km2), shallow body of water in the middle of the Netherlands, with a mean water depth of 3.6 m. One of the major problems in the lake is its decreasing ecological value which is, among other reasons, caused by a gradual increase of suspended sediment concentration and associated increase of light attenuation in...

Measurements and modelling of the effects of seagrass meadows on flow and sediment transport in the Bay of l’Ecluse, Dinard, France

Seagrasses are a valuable but threatened part of coastal systems. To aid restoration attempts, a model has been made to study the effect of such flexible aquatic vegetation on flow and sediment transport. Because this model needs to be tested against field results, a field experiment was undertaken around an eelgrass meadow in Dinard, France....

Link Budget Analysis and Modeling of Short-Range UWB Channels

Ultrawideband (UWB) technology is an attractive alternative for short-range applications, e.g., wireless personal area networks. In these applications, transmit and receive antennas are very close to each other and the far-field condition assumed in most of the link budget models may not be satisfied. Under near-field conditions, variations in...

Using Stereo Photo Measurements to Analyze the Surfability of Ship Induced Waves

The objective of this paper is to demonstrate the use of Stereo Photogrammetry (SP) measuring ship-generated waves and to determine under which conditions they are suitable for surfing. A physical experiment is conducted to gain insight in ship wave behavior under specific conditions. Waves are generated by a hull and are measured using SP. It...

Measurement errors of instruments for velocity, wave heigt, sand concentration and bed levels in field conditions

Field measurements of hydrodynamics (fluid velocities and wave height), sediment dynamics (sand concentrations) and morphodynamics (bar behaviour) as performed during the COAST3D campaigns at the Egmond site in 1998 and at the Teignmouth site in 1999 inevitably involve the problem of the accuracy of the measured variables. The measurement errors...

Near-Bed Cohesive Sediment Processes: Development of a Self-Contained System for Long-Term Field Measurements

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...
