Hydrobiogeochemistry in dynamic river corridors across various scales

Session ID#: 85507

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 as the river corridor systems are subject to dynamic forcing over a wide range of timescales. Many traditional studies utilize snapshot or time-averaged observations, thus ignoring this inherent dynamism. 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. Additionally, we seek eLightening presentations that provide novel insight, including case studies, into the dynamic nature of rivers and their surroundings. We encourage video, active plots, and other innovative and engaging presentation techniques to highlight river corridor dynamism.
