In this paper, a simple model concept is presented to describe the dynamics of road runoff and suspended-solid transport from a small urban catchment in northern Sweden. The study period stretches from March 28 to May 28, 2000, including both snowmelt and rainfall. A modified degree-day method is used to describe the snowmelt and the transport of suspended solids is described by a linear build-up function and a wash-off model. The model was verified through measurements taken from March 22 to May 22, 2001. The results from the simulations showed that the simple model concept was capable of describing the dynamics of road runoff and suspended solids rather well, based on the continuous course of events for the whole modelling period. However, if the model was used for simulating a snowmelt period, or single events during snowmelt, the model approach would be too simple.
