Validating Modeled Streamflow Transport Dynamics and Floodplain Habitat Connectivity for Larval Endangered Fish of the Middle Green River, Utah

Institute: Colorado

Project Summary: This field experiment will involve the release of buoyant-neutral beads and marked larval fish from a point source location on the Green River in Utah, and measurement of the distribution of beads and larvae throughout the water column at three to five cross-sections downstream of the release point. These releases likely will be made during one or multiple high-flow events in May 2019. The primary objective of this experiment is to test the validity of the USGS’s quasi-3D hydraulic transport dynamics model which was recently developed for a 22.8-km reach of the Green River. In 2018, the USGS Geomorphology and Sediment Transport Laboratory (GSTL) conducted preliminary transport modeling based on the river bathymetry, streamflow, and state data collected during February and March 2018 field deployments.
