Local Hydroelectric Energy Storage: A feasibility study about a small scale energy storage system combining hydropower, gravity power, spring power and air pressure

Renewable energy sources, like wind- and solar power, are expected to generate a greater part of the electricity production in the Netherlands each upcoming year. Besides all the advantages, the energy supply of these renewable energy sources fluctuates heavily as they mainly depend on the amount of wind and sun. Therefore, the electricity...

The effect of pH and the solids composition on the settling and self-weight consolidation of mud

A demand to use mud as fill material for land reclamations has emerged over the past years. Such reclamations start with pumping a muddy suspension into an area enclosed by dikes. The particles in suspension then settle to form a mud layer, so that the supernatant can be removed. This filling process may be repeated several times to completely...

The impact of re-surfacing groins on hydrodynamics and sediment transport at the Delfland coast

Objective Due the coastal protection program along the Dutch coast, the groins that first defended the coast against erosion, are now covered under sediment. Due to erosion the covered groins will resurface however. The objective of this study is to investigate the effect of the resurfacing groins on the hydrodynamics and sediment transport....
