RIBASIM computes the flow composition at any location in the basin. Sources like runoff from a sub-catchment, agriculture drainage, domestic and industrial sewage, reservoir water, groundwater, etc. are shown as components of the flow. This flow composition can be used as a basis for the analysis of the sources of water for the various users and thus as a first water quality assessment.
