This example demonstrates the new water balance presentation using a simple model. You can download the model from this link.
In this model, we have three Standhyd components. NHYD 1 and NHYD 2 connect and flow into Addhyd 4. The flow from Addhyd 4 is directed to a Soakaway Pit (NHYD 5), which includes an underdrain system. In the Soakaway Pit properties, we change the infiltration type to Green-Ampt to ensure GWI is calculated. Note that if you select the fixed-rate method, GWI will not be calculated.
Once the model is set up, run the simulation to generate the water balance.
