PERSiST simulates runoff.

PERSiST, the Pan-European Runoff Simulator for Solute Transport is a semi-distributed model operating at a daily time step. The model simulates runoff at one or more points in a river system using inputs of catchment characteristics and daily temperature and precipitation time series. The model has a user-friendly interface and has been designed to simulate hydrological conditions in boreal, temperate and Mediterranean catchments over time periods of 1 to 100+ years. PERSiST simulates both terrestrial and in-stream controls on runoff. Processes simulated include snowmelt, evapotranspiration, riparian zone infiltration and inundation and biogeochemically important summer low-flow events. PERSiST is able to simulate the effects of different land uses and land covers on runoff generation. The manner in which precipitation is routed through the catchment is extremely general. Depending on the manner in which the model is set up, it is possible to simulate riparian zones, drain flow, and water abstraction.
