ABSTRACTThis PAPER DESCRIBES the development, testing, and implementation of CHARM, a low flow management model for the River Thames between Windsor and Teddington. CHARM has been designed to help operational control staff to regulate river water levels and to define safe abstraction rates for pumping from the river into reservoir storage. Effective management of flows, levels, and abstraction rates is particularly important during periods of low flow when there is a potential conflict of interest between meeting the demand for water and satisfying minimum constraints for residual river flows and levels.CHARM resides on a microcomputer and evaluates the consequences of a contemplated set of actions, over a 24 hr period, within a matter of seconds. Results are displayed graphically to the operators, showing where constraints have been violated so that control decisions may be adopted or modified as necessary.
