EP53E:
Quantifying Complex Ecohydraulic Interactions Using Field, Flume, and Numerical Methodologies II


Session ID#: 8390

Session Description:
Flow-biota interactions play a fundamental role in shaping fluvial, estuarine, saltmarsh, lacustrine and coastal landscapes. Therefore, a good physical understanding of the effect of biota on aquatic systems is central to effective environmental management. This session focuses on the quantification of eco-hydraulic interaction within the three methodologies of in-situ field studies, laboratory-based experiments and conceptualised numerical modelling. Research topics include (but are not limited to): 1) capturing and characterising morphological complexity, 2) methods for directly simulating flow-biota interaction, 3) the effect of eco-hydraulic interactions on sediment and nutrient transport processes and 4) the transfer and upscaling of process knowledge between different spatial scales of interest. We particularly welcome work which highlights the interplay of these three methodologies in advancing our understanding of eco-hydraulic interactions.
