There is increasing evidence that altering climatic
conditions, land use practices or contamination influence physical, chemical
and biological soil properties, which are decisive for soil functioning
(filter, buffer, transformation, and water storage functions). Changes in these
properties have an impact on both water quantity and water quality due to
mobilization/release of substances from soils and sediments or by facilitating
the migration of substances through the soil layer towards the groundwater as
well as by contaminant transport from sediment layers into surface waters, and
vice versa. Although in
Current research activities focus on gaining of a holistic understanding of the river – sediment – soil – groundwater system. Particularly, investigations of key biogeochemical processes and the impact of global change on the filter and transport functions of soils are of interest. Insights from these research efforts are required to gain an improved understanding of the properties and the functional role of soils, as well as of the behavior and fate of pollutants.
