In the Rhine-Meuse Delta in the Netherlands, deep scour holes can develop very suddenly. The holes may form a potential risk for the stability of surrounding riverbanks, dikes, bridges, tunnels and buildings. A scour hole can mostly be the result of two conditions: local changes in hydrodynamical conditions or local changes in erosive capacity...

Due to the removal of mangrove forests, the coastal zone of Demak district has suffered from severe erosion. One of the proposed solutions to restore the sediment balance and encourage mangrove re-establishment, is the construction of semi-permeable dams. This study aims to optimise the design of such structures. A 2DH site-specific model was...

This thesis investigates the origin of observed current velocities at the Gemini offshore wind farm in 2015. Currents have been measured of 1.2 m/s while, based upon tidal and storm predictions, currents of only 0.7 m/s were expected. The aim of this research is to gain insight into the origin of these higher currents, taking into account the...

Since their development in the 1970s, mesoscale atmospheric models have been used for a variety of meteorological applications. Over the years, the models have evolved and nowadays, state-of-the-art atmospheric models are capable of operating on spatial resolutions in the order of kilometres. In the hydraulic engineering community, atmospheric...

The coastal bathymetry is one of the most essential inputs for understanding, monitoring and modelling the coastal environment. A remote sensing technique called marine radar may overcome disadvantages of present monitoring techniques and has the advantage to obtain measurements with a high spatial and temporal resolution. A Fast Fourier...

In the last century, various tidal rivers in Europe have seen a large tidal amplication, which is believed to be caused by the deepening and channelization of these rivers. Additionally, large increases in suspended sediment concentrations induced by flood dominance are thought to have decreased the effective hydraulic drag, enhancing further...

Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...

Numerical modelling for environmental flow applications, such as for rivers, lakes, estuaries and coastal flows, faces a trade-off between the numerical accuracy and the required computation time. This trade-off results in grids which typically contain 10 to 100 layers in the vertical direction. Such a grid resolution poses severe limitations to...

The Rhine River and the Meuse River discharge into the southern North Sea, and form the Rhine Region of Fresh Water Influence (ROFI) in front of the Dutch coast. A complex hydrodynamic system is generated, dominated by mixing from strong tides, wind and waves and the stratifying influence of the freshwater and solar heating. This influences the...

In the mass balance of a riverbed, some terms are usually assumed constant for reasons of simplicity. One of the terms assumed to be constant is the change in bedload layer, which is defined as the sediment transport divided by the particle velocity. To study the effect of this assumption, a numerical morphodynamic model has to be computed. For...

Little research was done in the past concerning the propagation of three dimensional effect in shallow wake flow caused by a roughness patch. Today’s research on related subjects is dominated by emerging obstructions in shallow water where the flow can be assumed as (quasi) two dimensional. However the relevance of a submerged obstruction with...

Lake Markermeer is a large and shallow freshwater lake in the center of the Netherlands. The lake was originally part of the Zuiderzee, a sea inlet of the North Sea. The lake is an important ecosystem, especially for water birds. The main problem in Lake Markermeer is the decreasing ecological value. High turbidity levels are believed to be one...
