Building on piles in floodplains [PDF]

, 2006
Last year in the Netherlands 15 locations were allocated along the Rhine branches where – under strong restrictions - it was allowed to build in floodplains. Building in floodplains may lead to a water level rise during floods and moreover, the river bed

Direct numerical simulation of the oscillatory flow around a sphere resting on a rough bottom

, 2017
The oscillatory flow around a spherical object lying on a rough bottom is investigated by means of direct numerical simulations of continuity and Navier-Stokes equations.

Simulating river flow velocity on global scale [PDF]

, 2005
Flow velocity in rivers has a major impact on residence time of water and thus on high and low water as well as on water quality. For global scale hydrological modeling only very limited information is available for simulating flow velocity. Based on the

Fine Sediment in Mixed Sand‐Silt Environments Impacts Bedform Geometry by Altering Sediment Mobility

Water Resources Research
Geometric characteristics of subaqueous bedforms, such as height, length and leeside angle, are crucial for determining hydraulic form roughness and interpreting sedimentary records.

Bedform dimensions under supply limited conditions [PDF]

, 2008
The volume of mobile sediment on the river bed is the primary control on the dimensions of the bed forms that develop. If an unlimited supply of sediment is available the bed form dimensions which develop are determined by the water depth, the flow ...

Bed roughness under partial transport conditions

, 2007
Reliable roughness models are of great importance, for example when predicting water levels in rivers. However, classical roughness models, based on fully mobile sediment beds, are not adequate for conditions in which only part of the bed is mobile (partial transport).
