Hydrosedimentological Response to Estuarine Deepening: Conceptual Analysis

This paper describes the effects of anthropogenic deepening of tidal rivers in a conceptual way, with focus on tidal distortion and the residual transport of coarse sediment, driven by asymmetries in peak velocity. The rivers under consideration are fairly small, with small river discharge, and may have irregular hypsometry, with substantial...

Scour holes in tidal rivers with heterogeneous subsoil under anthropogenic influence

Over one hundred scour holes are located in the Rhine-Meuse delta. These scour holes have relatively large depths and steep slopes and could pose a risk to the stability of river banks and hydraulic structures, especially since some scour holes are still growing. Scour holes develop at locations where either the hydrodynamics or the erodibility...

Laboratory observations and calculations of the depth averaged flow patterns in a square harbor on a tidal river

Many harbors in the world suffer from siltation in their basins and in many cases removal of the deposited sediment leads to high costs. This siltation results from a net transport of sediment into the harbor caused by the water motion in the harbor entrance. The water motion is very complex and of a three-dimensional nature. Three main...

Optimization of monitoring networks in rivers in tidal lowlands

In this project it is attempted to find optimum values of distances between measurement locations on a tidal river. The study aims at estimating waterlevels along a tidal river as well as their confidence intervals when measured values at some fixed points are given. Several procedures to estimate the waterlevels are compared with each other. In...

De berekening van getijden en stormvloeden op benedenrivieren

Ter oplossing van het, aan de "Staatscommissie inzake hooge waterstanden als gevolg van de afsluiting der Zuiderzee" voorgelegde probleem, heeft de voorzitter dezer commissie, de groote natuurkundige H. A. Lorentz, als eerste een betrouwbare en practisch uitvoerbare methode gegeven tot het berekenen. van getijverschijnselen in zeeannen. Deze...
