I would like to determine pressure head of a groundwater system of unsaturated soil. I tried to do coupling with modflow and hydrus-1D for determining pressure head. But failed. Could anyone please help me on this?
tested with the addition of ventury in the source water. If the venturi pipe is pressurized it will suck the surrounding water and will increase the pump water flow to help the pump suction excess discharge as pump output.
How did you try to couple and what kind of coupling? You can use the HYDRUS-1D estimated recharge as input to the MODFLOW and cross-check your results and fine-tune the parameters. Both models can interact with each other through recharge.
