Door natuurontwikkeling langs grote rivieren wordt ruimte geboden aan natuurlijke processen als overstroming, erosie, sedimentatie en begrazing. De vestiging van struik- en boomsoorten (ooibos) maakt onderdeel uit van deze spontane natuurontwikkeling. In 2001 is onderzoek gestart langs de Waal bij Beuningen, waarbij gekeken wordt naar het proces va...
The Netherlands Centre for River Studies (NCR) aims to provide an open platform for all people interested in scientific research and communication on river issues. To that end NCR organises once a year the socalled NCRdays, where on two consecutive days scientists present their ongoing river studies, in order to maximise the exchange of ideas and e...
Predicting spatial patterns and intensity of soil erosion and deposition in landscapes is problematic in areas where few experimental data are available. Yet it is in these regions that the ability to extrapolate local field evidence could be most useful for locating the sources of sediments. This thesis aims at using and further developing existin...
In this study, the solid-solution partitioning of Cd, Cr, Cu, Ni, Pb, Zn and As in floodplain soils of the Dutch part of the rivers Rhine and Meuse is assessed by combining extensive field sampling with advanced geochemical modelling. The aim of this study was threefold: to develop tools to study the solid-solution partitioning of the heavy metals,...
Poster outlining a research on the impact of floodplain sedimentation on vegetation; quantifying nutrient input
Het natuurreservaat `Het Springendal¿ heeft jarenlang te kampen gehad met verdroging, verzuring en vermesting. Vanaf de midden negentiger jaren is gewerkt aan herstel van het gebied. Een experiment is uitgevoerd om met behulp open bodemdrempels, geconstrueerd als keiendammetjes, de beekbodem geleidelijk te verhogen. Dit geleidelijk herstelproces is...
1. We sampled a set of 93 lakes situated in the floodplains of the lower River Rhine in search for morphometric and other factors that explain their variation in clarity. 2. Lakes with a drop in summer water level were less turbid at the time of sampling, mainly because of a lower concentration of inorganic suspended solids (ISS). 3. We also found ...
Investigations have shown that visible-near-infrared (VNIR) spectroscopy can accurately determine soil properties under laboratory conditions. In situ assessment of soil properties is of great benefit for several applications, as spectra can be acquired fast and almost continuously. The present study used partial least squares (PLS) regression to e...
Water and nutrient balance are among the main concerns about the sustainability of our soils. Numerous computer models have been developed to simulate soil water and solute transport and plant growth. However, use of these models has often been limited by lack of accurate input parameters. Often, the limiting input parameters are water retention an...
