Modeling hyporheic zone characteristics in alternate bars under different stream flow, ambient groundwater and sediment anisotropy.

The data is related to the paper \"The Effect of Streamflow, Ambient Groundwater, and Sediment Anisotropy on Hyporheic Zone Characteristics in Alternate Bars\" published by Monofy, A., & Boano, F. (2021) in the journal of water resources research (WRR). The study is based on a numerical model of hyporheic flow in a built synthetic river reach with imposed alternate bars geometry. Five river flow discharges are investigated, and under each discharge value, three groundwater flow conditions are examined; neutral condition, where there is no groundwater flux on the bottom of the domain; losing condition, where the groundwater domain is losing flow through its bottom (to an imaginary aquifer); gaining condition, where the groundwater domain is gaining flow through its bottom (from an imaginary aquifer). In case of gaining and losing conditions different values of groundwater are tried by creating different simulations for each specific river flow and groundwater condition (in total 43 simulations). The data are organized as follows; five major files represent five river flows, in each file, there are three sub-major files representing three groundwater conditions (neutral, gaining, and losing). Inside neutral files, the data obtained from the surface water modeling as well as groundwater modeling and particle tracking are provided in .csv files. while for losing and gaining conditions, the files are subdivided based on the value of imposed groundwater flow. The .csv files contain the pressure heads on streambed, negative fluxes into the streambed, positive fluxes out of the streambed which can be used to map the overall flux distribution through the bed, and finally the results of particles tracking, in which each pathline of the hyporheic flux is defined with its associated characteristics, as residence time, maximum depth, hyporheic flux ...etc.
