Coupling groundwater modeling and biological indicators for identifying river/aquifer exchanges
Future climate changes and the resulting modifications in anthropogenic activities will alter the interactions between rivers and groundwater. The quantification of these hydraulic interactions is absolutely necessary for achieving sustainable water use and requires accurate analytical methodologies. This report proposes an interdisciplinary approach to the quantitative and qualitative characte...
متن کاملRiverbed Clogging and Sustainability of Riverbank Filtration
Clogging refers to a reduction of riverbed hydraulic conductivity. Due to difficulties in determining the thickness of the clogging layer, the leakage coefficient (L) is introduced and used to quantify the recoverable portion of bank filtrate. L was determined at several riverbank filtration (RBF) sites in field tests and using an analytical solution. Results were compared with data from simila...
متن کاملHydraulic aspects of riverbank filtration—field studies
The Düsseldorf waterworks have been using riverbank filtration since 1870 with bank filtration as the most important source for public water supply in this densely populated and industrialised region. There have been many threats to this supply in the last few decades—e.g. poor river water quality, heavy clogging of the riverbed, accidental pollution—which had to be overcome. First field studie...
متن کاملGenetic Variation and Biological Control of Fusarium graminearum Isolated from Wheat in Assiut-Egypt
Fusarium graminearum Schwabe causes Fusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss of wheat and other cereal crops. Twelve isolates of F. graminearum were collected from naturally infected spikes of wheat from Assiut Egypt. These isolates were compared using SRAP. The results indicated distinct genetic groups exist within F. graminearum, and dem...
متن کاملOccurrence of methyl tert-butyl ether (MTBE) in riverbank fiftered water and drnking water produced by riverbank filtration. 2.
Bank filtration of river or lake water represents an efficient and natural purification process used for the drinking water production in many countries and at an amount of about 15-16% in Germany. From experiences over decades particularly at the river Rhine and Elbe, it is known that the occurrence of persistent pollutants in river water can represent a problem for the quality of drinking wat...
