EP016:
Floodplain Connectivity from Tributary to Distributary Systems





Session ID#: 26012

Session Description:
The timing, duration, and extent of exchange between channels and floodplains are controlled by multiple environmental factors. Thus, floodplain connectivity varies across landscapes and can directly impact the hydrology, sediment transport, and biogeochemistry of these systems. While much focus has been on alluvial floodplains, the conceptual models developed for these systems can often be applied to deltaic floodplains as well. Floodplains along the entire longitudinal gradient, from tributary to distributary systems, offer opportunities to compare connectivity under a variety of conditions and to understand the mechanics. Understanding floodplain connectivity continues to be of interest both from the perspective of ecosystem services provided (nutrient retention, flood control, sediment and carbon accumulation) and as direct and indirect human alteration to landscapes changes this connectivity. This session welcomes presentations quantifying alluvial and deltaic floodplain connectivity on large and small scales and linking the role of water, sediment, and chemical exchange to floodplain dynamics.
