Computational dataset for hyporheicFoam

This repository is for the computational dataset of the cobble-driven hyporheic exchange simulation using hyporheicFoam (https://www.hydroshare.org/resource/2599efbdbdc04e669959da368ee0b7c0/).

We generated an idealized synthetic channel with an array of four cobbles placed on the sediment bed in a staggered pattern. The surface and subsurface domains are 0.3 m and 1 m deep, respectively. The channel velocity is set to 0.1 m/s. The axial diameters of the cobble are 10, 8, 6 cm in streamwise, lateral, and vertical directions. For this example, the spacing (the number of diameters between cobble centers) is 2 and the protrusion ratio (the ratio of the height of the protruded part of the cobble to the total height of the cobble) is 5%. For the cobble-water interface, a no-slip condition is applied whereas a no-flow condition was imposed on the cobble-sediment interface.

Users can run surface flow simulation by executing \"Allrun.surf\" which starts at \"0\" and ends at \"100\" and the subsurface flow and transport simulations by executing \"Allrun.subs\" which starts at \"101\" and ends at \"200100\". In \"postProcessing/subsurface/totalC_sub\", the amount of solute residing in the sediment bed is computed and stored while running the subsurface simulation.
