In the application of American River Basin (inside the project DMIP-2/NWS) the TOPKAPI-X has generated the best simulation during the calibration period (Smith et al., 2013).

The new conceptualization of the two soil layers plus Green and Ampt has allowed a correct reproduction of peak floods, the base flow and recession curves. Thanks to the model of infiltration even small summer events are simulated correctly. The evaluation indices confirm the good behavior of the model, which returned a Nash-Sutcliffe coefficient equal to 0.90 calculated over 9 years of simulation with hourly time step.
