Special Session - Integrating Biological/Biogeochemical Measurements with Complexity in Hydraulics and Geomorphology in Streams I
The growing field of ecohydrology has arisen through collaboration of ecologists, geologists, hydrologists, and engineers interested in an integrated approach to understanding heterogeneous stream ecosystems and the two-way interaction of physical and ecological processes. While progress has been made in developing an interdisciplinary understanding, methods for combining measurements across disciplines are not well established. This situation makes interpreting results and comparisons to other streams/watersheds difficult. This session will bring together researchers who have attempted to correlate an ecological response with varying hydrologic conditions, scale point measurements to a reach-scale or broader, or compare results among streams of varying geomorphological, hydrological and ecological composition. A major goal of this special session is to compare extrapolation methods of measurements across disciplines and to address the questions: Is there universality in ecological-geological-physical interactions? What is the best way to scale and model these interactions across space and time?
