               4.3              Well Features & Attributes

               Wells can be added to the model domain to:

                   •  add pumping stress or a source of water (e.g., injection well) at a point location
                   •  add a point-source of a pollutant/solute in groundwater
                   •  place particles at a point location or in a circle around a point location (see Section 5.6)
                   •  monitor simulation results (both head and concentrations) and compare with observations (see
                       Section 6.1).

               To  add  a  well  feature to  the  model  domain,  LM  click  on  the  ‘Well’  button  along  the  left-side  of the
               MAGNET Modeling Environment (see Section 2.5).  The cursor will become a cross-hair, allowing for
               placement of a well with a single-click of the LM button.  This will open the Well Input Options menu (see
               Figure 4-22). The coordinates (latitude and longitude) of the well feature are displayed in degree-decimal
               form in the text boxes next to ‘Lat:’ and ’Lon:’.
                                                         9













               9  The location of any well can be updated by entering new values in these text-boxes, then hitting ‘OK’.
