Abstract

Exchanges of water and solute between stream flow and flow through river bed porous media are known as hypoerheic exchanges. Hyporheic Exchanges transfer water and nutrient to the organism lived in the hyporheic zone, so affect ecological conditions and food cycle. One of the important factor effects on these exchanges is pressure gradient along the bed form. Riffle-Pools are geomorphic features of rivers which pressure gradient along them drive Hyporheic Exchanges and recently considered in river restoration projects. The goal of this study is to compare the hyporheic flux and Residence Time of flow within sediment bed, in 2D and 3D Riffle-Pool. For reaching this goal, the surface flow simulated with OpenFAOM and then the results of pressure along bed form, set as a boundary condition on groundwater model (MODFLOW software). The results show that, by increasing bed form amplitude, Hyporheic Exchanges flux increases by 26 percent for both 2D and 3D models, and Residence Time decreases by 36 percent for 2D and 41 percent for 3D models. Also, comparison of 3D Riffle-Pool with equal 2D model shows that Hyporheic Exchanges flux and Residence Time increase by 3% and 4%, respectively.
