Hydrobiogeochemistry in River Corridors across various scales
Session ID#: 161421
Session Description:
Hydrologic exchange flows in river corridors play a major role in watershed nutrient cycling by mixing waters of different composition and stimulating biogeochemical reactions. Hydrologic exchange flows and the associated biogeochemical processes show significant spatiotemporal variability due to complex interactions of surface water/groundwater and inherently heterogeneous solute transport through drainage networks. We invite presentations that advance our process understanding of nutrient cycling in river corridors, including (a) geomorphic and hydrogeologic characterization to improve hydrobiogeochemical models, (b) mechanistic representation of processes in numeric models, and (c) bridging scales between observations and models.
