EFAS hydrological models transform the meteorological forcing forecasts into hydrological forecasts by mimicking the hydrological land processes by a set of equations. In EFAS, the hydrological model LISFLOOD is primarily used for medium- and seasonal-range forecasts, whilst conceptual hydrological algorithms are used for the flash flood indicators.

The hydrological modelling engine of CEMS-Flood, for both EFAS and GloFAS (since version 3) is the LISFLOOD hydrological model.

LISFLOOD is a spatially distributed rainfall-runoff-routing model. It was first developed at the Joint Research Centre in 2000, and has been used for operational flood forecasting at the pan-European scale since the beginning of EFAS. Driven by meteorological forcing data (of precipitation, temperature, potential evapotranspiration, and evaporation rates for open water and bare soil surfaces), LISFLOOD calculates a complete water balance at a the relevant time step (6-hourly or daily time step for EFAS, daily for GloFAS) for every 5km grid cells of the EFAS spatial domain. The runoff produced at every grid cell is routed through the river network using a kinematic wave approach. The model also includes options to simulate lakes, reservoirs and water abstraction. LISFLOOD is coded using the Python programming language and a PCRaster Python extension. LISFLOOD and its associated tools are all openall open-source. The LISFLOOD source code, model documentation, test catchments and tools can be found at the LISFLOOD OS page.
