Groundwater ionic profiles, with particular regard to bioavailable nutrient (N, P, and K) levels, were studied in a flooding alluvial grassland of the river Meuse. The observed variations were related to different groundwater levels and hydrolog[...]

PAH contamination levels were determined in the suspended matter of two French rivers, the Seine and the Rhone, and compared to those available for other major European rivers. Hydrodynamic characteristics, such as the amount of suspended matter[...]

A new version of the 'Riverstrahler' model has been developed for modelling riverine transfers of nitrogen from diffuse sources within the watershed, using land use data as a forcing function, together with an adjustable riparian transfer coeffi[...]

Routine measurements of river discharge and total suspended sediment concentration (TSS) are combined with regular analyses for particulate and dissolved cadmium to produce a box model that allows us to propose a cadmium mass balance for the Lot[...]

The Northern Vosges streams are subjected to acidification upstream and to eutrophication downstream. A bioindicator scale of the degree of eutrophication and of the level of acidification, based on four aquatic macrophyte communities, was estab[...]

We analyze the TSS distribution over the whole Seine basin (67 500 km(2), stream order 8) from: 1. a set of 236 stations sampled quaterly to bimonthly from the french national water quality monitoring network over the 1971-1997 period, 2. four s[...]

During the 17th and 18th centuries, the Rhone delta recorded high frequency fluctuations in water and sediment influx. These variations resulted from the drastic climatic changes that took place during the Little Ice Age, which were intensified [...]

The magnitude of the contamination of the river Marne by various herbicides of agricultural origin (triazines and phenylureas), led the CGE (Compagnie Generale des Eaux) and the IHC/LGA (Institut d'Hydrologie et de Climatologie/Laboratoire de Ge[...]
