dc.description.abstract | The residence time of solutes in catchments is longer during low-flow conditions, due to the lengthening of transport routes and
the decrease in transfer velocities. In rivers, transient storage depends largely on exchanges with channel storage and the
hyporheic zone and reflects the capacity of the river to buffer pollutant loads before they enter the aquatic environment of final
receptors. Our objective was to eval-uate the fate of solutes along a typical confined river of upland catchments. First, we calculate
lateral inflows using a variable-source hydrology approach. Then, water motion and quality in the river channel are predicted by
combining hydrodynamics and exchanges with channel storage and the hyporheic zone. The model is mainly parametrized from
literature data during baseflow conditions to mimic the fate of adsorptive and non-persistent pollutants. Residence time in surface
water, channel storage and the hyporheic zone were found to be sensitive to lateral inflows from groundwater seepage. Channel
storage is the main process controlling residence time in upstream conditions, where the riverbed is mainly com-posed of stones
and bedrock. Downstream, along with the formation of sediment deposits and riffle-pool units, hyporheic exchanges also control
the lag time in the transfer of solutes. By integrating physically-based processes, the number of parameters is small, but the model
still requires a detailed description of stream geometry and morphology. It can be used to evaluate stream restoration or
catchment-river man-agement when detailed data of stream geometry and morphology are available. | es |
