When runoff generation is calculated using soil moisture simulation, the concept of hydrologic response units (HRUs) is applied. A catchment area is divided into a number of hydrologically homogeneous areas, i.e. areas of the same soil type and the same land use. For each hydrologic response unit there is exactly one assignment of land use and soil type. The discharge resulting from a hydrologic response unit is output from the sub-basin element to which the HRU belongs, i.e. all hydrologic response units release discharge with the same time delay, independent of their location within the sub-basin.
