How to import polygons of recharge multipliers into the grid model in GMS?


Recommended Posts

I have a transient model that has around 1500 grid cells. For temporal recharge, I used polygons to import recharge Timeseries data into the grid model. Now, I have to import the polygons of multiplying factors for recharge. The problem here is GMS does not have an option to import multiplying factors from polygons to grid cells. Can anyone help me in this regard?

If I have this right, multipliers for Recharge in MODFLOW are not applied on a cell-specific basis, but rather by stress period across the entire grid.  Therefore, if you want different multipliers for each stress period, you can do this in a spreadsheet (one column), copy the cells, and drop them into the GMS recharge input box.

If you need to multiply different areas of your grid, you will have to do that manually, but creating data sets (one for each recharge and one for the multipliers) and multiplying the data sets before pulling them into the recharge rate input.  Right now, that's the only way I can think of, but maybe others have different ideas.
