CHD Objects

Use the Show or Hide Objects dialog box to show the objects related to the CHD package (under "MODFLOW Features") and hide all the other objects. Three objects define the CHD Boundaries (fig. 81). Make sure Object|Select Objects is selected and double click on the point object on the upper left corner of the grid. In the Object Properties dialog box, select the MODFLOW Features tab. The object uses the starting and ending times of the single stress period. (If there were more than one stress period, the times could encompass several stress periods.) The starting and ending heads were both set to 30. Two parameters are defined for the CHD package, but this object does not use either of them (fig. 82). Click on Cancel to close the Object Properties dialog box.
