Abstract: A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this model the user can evaluate a 'best' system operation analysis for multipurpose reservoir regulation to obtain target water quality conditions at user specified control points. The user may select to operate the system for a balanced reservoir pool operation and its associated water quality or to allow for a modified flow distribution between reservoirs to improve the water quality operation. The water quality routines are capable of analyzing water temperature and up to three conservative and three nonconservative constituents. If at least one of the nonconservative constituents is an oxygen demanding parameter, dissolved oxygen can also be analyzed. A special option has been added to analyze phytoplankton and associated nutrients.
