TOWARDS AN IMPROVED UNDERSTANDING OF BIOGEOCHEMICAL PROCESSES ACROSS SURFACE-GROUNDWATER INTERACTIONS IN INTERMITTENT RIVERS AND EPHEMERAL STREAMS
In river networks, the rates, type, and location of biogeochemical processes are strongly influenced by the temporal and spatial distribution of surface water-groundwater (SW-GW) hydrological connections. However, most of our current understanding in the field is based on studies that use perennially-flowing rivers and streams as model systems. Here, we outline a conceptual framework for predicting the effects of intermittent streamflow and drying events on biogeochemical processes across river networks, which was developed in collaboration by members of the European SMIRES (Science and Management of Intermittent Rivers and Ephemeral Streams) network. Beginning with extensive literature reviews of hydrological and biogeochemical research in intermittent rivers, we used conceptual models of SW-GW hydrological connectivity to predict the diversity and rates of biogeochemical processes across intermittent rivers networks. These predictions then allow us to identify key knowledge gaps and make recommendations for future research into the biogeochemistry of intermittent rivers and ephemeral streams.
