The conventional Vensim model uses two parallel reservoirs to simulate the slow and fast flows in karst systems, which can hardly simulate the existing nonlinear hydrological process. This paper proposed a revised Vensim model (R-Vensim) to further enhance its ability to simulate the nonlinear hydrological process in karst systems. This revised version changed one linear reservoir in the Vensim model into a nonlinear reservoir and considered the variation in the distribution coefficient under different hydrological conditions. The two models were applied to simulate the discharge of karst spring S31 located at the Yaji experimental site. The simulation results indicated that the R-Vensim model can reasonably reproduce the discharge dynamics under different precipitation conditions, whereas the Vensim model underestimated the fast flow peaks and overestimated the slow flow peaks. In the study catchment, the fast flow was almost linear, whereas the slow flow was highly nonlinear. In the calibration period, 78.5% of spring discharge came from the nonlinear reservoir. The results showed that, considering the nonlinear hydrological process was a key issue to accurately simulate the karst spring, particularly for the slow flow condition.
