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, 2020

Objective:
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.

Approach:
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.
