H11N:
Groundwater-Surface Water Interactions: Identifying and Integrating Physical, Biological, and Chemical Patterns and Processes Across Scales I

Submit an Abstract to this Session



Session ID#: 34456

Session Description:
Groundwater-Surface Water (GW-SW) interactions occur over a range of spatial and temporal scales, which are frequently complex, nested, and coupled. The interfaces between GW and SW environments (i.e., hyporheic and benthic zones, riparian corridors) often function as biogeochemical hotspots and can have substantial implications for whole-stream processes of ecological significance. Processes, such as thermal and flow regulation, nutrient cycling, microbial metabolism and habitat structure, require identifying and integrating interdisciplinary principles from hydrology, geomorphology, biogeochemistry and aquatic ecology. Despite increased efforts in GW-SW interaction research, open questions remain in analyzing and predicting coupled physical, chemical, and biological patterns and processes across scales.

This session aims to link GW-SW researchers and their study of specific processes to facilitate a more complete understanding of GW-SW processes (e.g., identifying linkages and separating complex signals into individual processes). Thematic sub-sessions will be organized around research identifying and integrating multidisciplinary processes through observations, experiments, and models.
