Output:Run Summary File
The run summary contains a summary for each event simulated and simulation totals after the last event summary. For each event the run summary file contains a number of sections: title, start-up inputs, mass-conservation, warnings, and outputs. If Richards’ equation is used to simulate the unsaturated zone a separate mass-conservation section is included in each event summary. If saturated groundwater is simulated then a separate mass-conservation is included in each event summary. The following is an example of the run summary file output for a continuous simulation with a single event. In this example Richards’ equation is used to simulate the unsaturated zone and lateral groundwater flow is calculated, along with interaction with the stream network.
