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.本仓库用于存储使用hyporheicFoam开展的砾石驱动潜流交换模拟的计算数据集，相关资源链接为：https://www.hydroshare.org/resource/2599efbdbdc04e669959da368ee0b7c0/。 本研究构建了理想化人工河道，在沉积物床面以交错排布方式布置了四颗砾石。地表域与地下域的深度分别为0.3米与1米，河道流速设定为0.1 m/s。砾石沿顺水流方向、横向与垂向的轴向直径分别为10 cm、8 cm与6 cm。本示例中，砾石间距（即砾石中心间距与砾石直径的比值）为2，突露率（砾石突露部分高度与砾石总高度的比值）为5%。在砾石-水界面施加无滑移边界条件，而在砾石-沉积物界面施加无流动边界条件。 用户可通过执行"Allrun.surf"运行地表水流模拟，该模拟的时间步范围为0至100；通过执行"Allrun.subs"运行地下水流与溶质输运模拟，其时间步范围为101至200100。在地下模拟运行过程中，沉积物床内的溶质总量会被计算并存储于"postProcessing/subsurface/totalC_sub"路径下。
