The hydrology in coastal environments is influenced by complex interactions between terrestrial, marine, atmospheric, and human processes. Effective management, restoration and protection of coastal water resources and ecosystems require improved measurements, modeling and prediction of natural surface and subsurface hydrological processes and the impacts of human activities. This session invites submissions that explore natural processes and the effects of human activities on coastal hydrology and hydrogeology. Topic areas include: groundwater-surface water interactions in coastal environments, including their effects on water and chemical fluxes; hydrologic controls on sediment supply, geomorphology and/or salinity; contamination of coastal groundwater or surface waters; and impacts of climate change and human-driven alterations on coastal hydrological/hydrogeological processes.
