Abstract: The climate change may lead to an increase in the frequency of extreme precipitation events and floods as well as changes in frost/thawing cycles. This will have impacts on the performance and life time of road infrastructures. The frequency of road closures and other incidences will probably increase. The aim of this study is to develop models predicting the run-off dynamics during conditions of overland flow due to snowmelt and partially frozen soils. A small agricultural catchment with detailed information on runoff in Norway have been used to test 3 different existing models (MIKE SHE, LISEM and CoupModel). The models evaluated differ with respect to aggregation level (time and space) and representation of the hydrological processes. Especially winter related processes as snow accumulation, melt and infiltration into partially frozen soils are discussed.
