Effects of saline water downward intrusion on nested groundwater flow systems

Attached are the software of HydroGeosphere, its input files and the output results. 

In the input files, there are totally 7 cases, including the base case and 6 test cases. The model can be run in Linux. The grok.x reads the Toth.grok to pre-process the model. The hgs.x is the main program to conduct numerical calculation. hsplot.x is used for the post-process to transfer the simulation results for viewing in Tecplot.

In the output files, the modeling results of the base case when c equals 0, 35, 100, 200 g/L are presented. The vertical positions of the internal stagnation points of the 7 cases are summarized in the excel file.
