11.3. Hydrograph

To create hydrographs from simulation results, use the “Hydrograph” function under the “Results” drop-down menu. Ensure model results are imported from the .PLB file. In the “Create Hydrograph File” dialog box, choose a directory for the hydrograph file, enter a name, then click “Save.” Groundwater-head data from monitoring boreholes and piezometers exports to a .DAT file. This file includes time steps, dates, well IDs, and groundwater-head data for all time steps. If the monitoring location becomes dewatered during simulation (groundwater head drops below the monitoring level), the hydrograph file contains “unsat” appended to the head value. If the monitoring location is mined out during simulation, the hydrograph file contains “mined” appended to the head value. Plot this data using Excel or other plotting software, as shown in Figure 11.3.
