This paper investigates the capability of the physically-based modelling system MIKE SHE to simulate the hydrological behaviour of the North Kent Grazing Marshes, UK. The MIKE SHE code is applied to a small underdrained catchment, Bells Creek, located within the marshes. The principal parameters used for model calibration are briefly discussed and potential sources of uncertainty (eg rainfall input and pumped discharges) in the simulation results are highlighted. The results of applying the calibrated, baseline model to two different periods reveal that water flow through macropore channels may play an important part in the hydrology of the soils of the catchment. The impacts of removing the artificial drainage system and changing land use in the catchment are investigated with reference to discharge and soil moisture storage.
