Effects of vertical confinement on gelation and sedimentation of colloids [PDF]
, 2017 We consider the sedimentation of a colloidal gel under confinement in the direction of gravity. The confinement allows us to compare directly experiments and computer simulations, for the same system size in the vertical direction.

VALUING MARGINAL CHANGES IN THE QUALITY OF AN ENVIRONMENTAL ASSET [PDF]
We present a model that extends the replacement cost theory to cases where benefits are restored for multiple years. Our theoretical framework derives a functional relationship between investments expenditures and environmental benefits. By extending the

Reconstructing more than 40 years soil re-distribution in two Taiwanese watersheds [PDF]
Taiwan is a little smaller than the Netherlands, an island surrounded by the sea and has a population of circa 23 million. Add a central range of steep mountains and it is clear that the pressure on living space and natural resources is enormous. This is

Nutrient Leaching from Reservoir Bottom Sediments
Chemical Engineering Transactions, 2013 Erosion is one of the most important pathway of sediment entries into river systems. Sediments as a pollutant is harmful by itself and is even more so when combined with contaminants, such as heavy metals, nutrients, pesticides and other organic micro-pollutants.
