The first step in using this utility is to identify the model zones by assigning a zone budget | The first step in using this utility is to identify the model zones by assigning a zone budget ID to each of the cells in the grid. The zone budget ID is an integer value. It can be associated with polygons in a MODFLOW conceptual model in the map module. The ''zone budget ID'' property is listed in the ''Areal Properties'' column of the ''Coverage Setup'' dialog. These IDs are then assigned to the appropriate grid cells when the '''Map→MODFLOW''' command is selected. The IDs can also be assigned directly to cells by selecting a set of cells and selecting the '''Cell Properties''' command in the ''MODFLOW'' menu. | ||
A ''Zone Budget IDs'' item is also included just below the MODFLOW icon in the [[GMS:Project Explorer|Project Explorer]] window.

Once the zone budget IDs have been assigned, the flow budget for each zone can be viewed by selecting the '''Flow Budget''' command in the ''MODFLOW'' menu. This brings up the ''Flow Budget'' dialog. There is a ''new zone selector'' combo box at the top of the dialog. The flow budget associated with the selected zone is shown in the table. The combo box includes an "All zones" option that displays a summary for all zones in the model. Also, turning on the ''Use all time steps toggle'' will create a flow budget report for each time step in the current MODFLOW solution. | Once the zone budget IDs have been assigned, the flow budget for each zone can be viewed by selecting the '''Flow Budget''' command in the ''MODFLOW'' menu.

The flow in flow budget is displayed as positive when flow is from the upper face to the lower face, left face to right face, and back to front. | ||
