Research Project: Effects of Surface-subsurface Hyporheic Exchange Processes on Chemical Transport and Transient Storage

Location: National Soil Erosion Research

Project Number: 5020-12130-003-12-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jun 1, 2016
End Date: May 31, 2021

Quantify how hyporheic exchange processes affect chemical transport in the surface flow and the transient storage in the bed sediments and derive parameters that can be used in a chemical transport transient storage model.

Conduct flow-through experiments in a multi-segment flume which has hydrologic controls for surface flow and subsurface flux to simulate different levels of hyporheic exchanges; identify dominant hydrologic processes affecting the transient storage of chemicals in the hyporheic zone; validate or improve the current hyporheic transient storage model concepts.
