As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream consequences resulting from changes in the upstream hydrologic system and salinity flow system.

Since the burden of water quantity and quality maintenance must be shared by the users, predictions are needed for quantity and quality changes which might result from contemplated development at any specified location within the river system. A close relationship between the hydrologic and salinity flow systems exist, thus making it necessary for an understanding of both systems in order to properly manage the salinity system.

This study reports the development of a hybrid computer simulation model of the water and salinity flow systems. The validity of the mode l is demonstrated by applying it to the Sigurd-Sevier subbasin of the Sevier River Basin, Utah.
