Old contaminated sediments in the Rhine basin during extreme situations

Sediments play an important role in water resources management. In the past, hazardous contaminants from municipal and industrial wastewater effluents and from agriculture were discharged in large quantities into the water bodies and accumulated within the bottom sediments. Today, relatively unpolluted recent sediment surface layers cover older...

The composition of suspended particulate matter during floodings of the river Meuse

Since the Industrial Revolution, mankind has disturbed the natural functioning of river floodplains by a high input of contaminants in the environment. Riverine suspended matter is the most important source for elevated levels of contaminants in floodplain areas. Previous research mainly focused on processes affecting the distribution of...

Van Korrel-kracht tot Kust Texel: Van Micro tot Meso

Het patroon van de volgende lezing is zeer eenvoudig te herkennen. De schering is de gang van micro- tot mesoschaal; de inslag het elimineren van periodieke processen die weliswaar beweging geven, maar geen resultante, die voor de daarop volgende grotere beschouwde schaal interessant is. Startend bij het gedrag van één korrel in een visceuze...

The history of the Dutch Coast in the last century
