Sturende factoren erosie, transport en sedimentatie in stroomgebieden Rijn en Maas

Het Delft Cluster-project Waterkwaliteit & Calamiteiten brengt de toekomstige ontwikkeling van de water- en slibkwaliteit in beeld onder invloed van extreme gebeurtenissen (gerelateerd aan bijvoorbeeld klimaatsverandering en verandering in landgebruik) en door de mens veroorzaakte calamiteiten (zoals lozingsongelukken). Dit rapport is het...

A Hybrid Approach to Combine Physically Based and Data-Driven Models in Simulating Sediment Transportation

The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...

Impact of sedimentation in the Dommel flood plain on heavy metal availability and bioaccumulation in flora and fauna

This report describes the application of the BioChem-DSS, being developed in the EU KP6-programme AquaTerra, BASIN R3 work package, with the aim to assist in the definition and improvement of management options for the Meuse region. A case study was carried out in a flood plain site of the river Dommel, a tributary to the Meuse. The present T0...

Modelling of Cohesive Sediment Transportation, Deposition and Resuspension in the Haringvliet Mouth.

In the Dutch coastal zone, where the marine environment is characterized by shallow depths and highly energetic hydrodynamic conditions, the cohesive sediments, or mud, play an important role in the local morphology. For instance, mud deposits and high concentrations of suspended particulate matter (SPM) occur frequently, especially during...

Data mining, knowledge discovery and data-driven modelling

The project was aimed at exploring the possibilities of a new paradigm in modelling - data-driven modelling, often referred as "data mining". Several application areas were considered: sedimentation problems in the Port of Rotterdam, automatic soil classification on the basis of cone penetration tests, prediction of water levels in the ocean,...

The Current Deflecting Wall: Mitigating harbour siltation; Set-up and integration of physical and numerical modelling techniques

The behaviour of fines released due to dredging: A literature review

In 2001a DIOC-projectwas started at Delft University of Technologyon the dispersion of fines during sand mining. In this project the behaviour and spreading of fines, which are released through the overflow of a dredging ship, is studied. Laboratory and field studies will be carried out to determine the behaviour and spreading of the fines....

Flow and salt transport in mangrove swamps

An analytical mathematical model is presented for flow and salinity in tidal mangrove swamps that is based one-dimensional approaches. The model is designed with the purpose to develop a method for rapid assessment of effects in mangrove swamps due to changes in river discharges that can also be used in situations with few data. A literature...

Reservoir sedimentation; a literature survey

A survey of literature is made on reservoir sedimentation, one of the most threatening processes for world-wide reservoir performance. The sedimentation processes, their impacts, and their controlling factors are assessed from a hydraulic engineering point of view with special emphasis on mathematical modelling. The objective of this study is to...
