In opdracht van het Deltaprogramma Kust is in kaart gebracht hoe het gesteld is met de huidige veiligheid van de Nederlandse kust. Als maat voor de veiligheid is de overstromingskans van de kustverdediging genomen. Deze overstromingskans kan opgevat worden als de kans op falen van een willekeurige locatie langs de kering, zodanig dat een...

Le 28 février 2010, vers 2 heures du matin, la tempête Xynthia atteint la côte occidentale de la France. A plusieurs endroits, les digues, dunes et d’autres ouvrages cédèrent, donnant lieu à des inondations du littoral. Plus de 50.000 hectares de terres furent inondées. Au total, la France compta 47 morts suite à la tempête, la plupart d’entre...

On the 28th of February 2010 at 2 a.m. the storm Xynthia hit the French Atlantic coast. The storm surge combined with the high tide and large waves caused flood defences to fail along the coastline from the Gironde (Bordeaux) to the Loire Estuary. A significant amount of land, (>50 000 ha) was consequently flooded and 47 people died as a result...

Op 28 februari 2010, rond 2 uur in de ochtend, bereikte de storm Xynthia de westkust van Frankrijk. Op meerdere locaties bezweken de waterkeringen, met kustoverstromingen tot gevolg. Meer dan 50.000 hectare aan land overstroomde. In totaal vielen in Frankrijk 47 doden, de meesten door het water en een enkeling door de gevolgen van de storm....

Large-eddy simulation (LES) is performed of a curved open-channel flow over topography based on the laboratory experiment by Blanckaert [“Topographic steering, flow circulation, velocity redistribution and bed topography in sharp meander bends,” Water Resour. Res., doi:10.1029/2009WR008303 (in press)] . In the experiment, the large-scale bed...

The flow of water through a river bend can be characterized as a turbulent open-channel flow that is dominated by streamline curvature. In order to adequately manage the planimetry of meandering rivers and the according safety aspects, the features of the flow and the associated turbulence have to be understood well. This thesis presents results...

After validation with experimental data, large-eddy simulation (LES) is used to study in detail the open-channel flow through a curved flume. Based on the LES results, the present paper addresses four issues. Firstly, features of the complex bicellular pattern of the secondary flow, occurring in curved open-channel flows, and its origin are...

Shallow flows are three-dimensional flows with two dimensions being signifcantly larger than the third dimension. Coherent structures, also called eddies, are areas in the flow, where velocity fluctuations are correlated, with a certain rotation. Although, generally, coherent structures of the order of the waterdepth contain most of the...
