• When drawing a rectangle, indicate the position of the first vertex with a single LM click in the
MDWA, and indicate the position of the vertex diagonal from the initial vertex with another single
LM click .

• When drawing a polygon, single-click the LM button to define the vertices of the polygon that will
define the zone extent.

The zone will appear in with circles at the vertex locations (see Figure 4-8). The location can of any vertex
7
can be changed by hovering the mouse over it and click-dragging to the new desired location
Hover the cursor over the circles at vertex locations and line segment mid-points to enable node editing
capabilities. Click-drag a node to adjust the size or shape of the model domain. After any change is made,
an ‘un-do’ button ( ) will appear next to the last node that was edited. Click on to return to the previous
node position. Note changes can only go back one node-edit in the current version of MAGNET.

Once the last vertex has been placed, LM click the ‘SaveShape’ button to finalize the zone. This will launch
the Zone Attributes menu (see Figure 4-8). This menu consists of 6 sub-menus: ‘Flow Property’;
‘Elevation’; ‘ Transport Property’’; ‘Biochemical’; ‘Sources and Sinks Head Dependent’; and ‘Sources and
Sinks Prescribed’. The following subsection provide more details on each sub-menu
If the zone needs to be discarded, LM click the ‘Delete’ tab to close the Zone Attributes menu and remove
the zone feature from the MDWA.

6 Allow for a brief period of time (i.e., at least 2-3 seconds) between LM clicks. Otherwise, the locations of the
vertices may not be consistent with what is desired.
7 Any vertex location can also be updated after finalizing the zone.
