State Water Institute Program Scope 17: Relative control of sediment gas content and changes in sediment surface elevation on streambed hydraulic conductivity and hyporheic exchange volume

A thorough investigation into the relative controls of temporal variability in streambed hydraulic conductivity in natural stream systems is needed to provide a framework for understanding its role as a potential design parameter for future efforts that intend to restore and promote hyporheic interaction. The objective of this work is to gain an understanding of the relative control that sediment gas content and streambed elevation changes (i.e. cycles of erosion and deposition) have on streambed hydraulic conductivity, and thus hyporheic exchange volume. This project will provide greater insights into natural influences on streambed hydraulic conductivity and hyporheic exchange.
