This is a simple reservoir operations model that calculates monthly inflows and withdrawals from a reservoir using a monthly time step. It is used to illustrate how an Excel VBA macro can be used to automatically generate plot image files when results are exported from GoldSim to an Excel file. Run the model and note that four image files are generated showing plot results (e.g. streamflow, reservoir volume and inflow/outflow rates, etc.).
The steps needed to develop this functionality were written up in a recent blog post here.
