Abstract

The modelling system could be a tool for predicting the flow regime in water management operations. The modified RAFLS model has exhibited a profound accuracy in the simulations of the Itezhi-tezhi/Kafue River system. The simulated flows and reservoir levels portrayed the dynamics in terms of time and magnitude. The use of the RAFLS model for water management in the subcatchment will result in flood protection, less evaporation from the shallow and wide natural reservoir, the Kafue Gorge Reservoir, available grazing grounds for the local communities, reclaimed fertile flood plains for farming by the local people, favourable flow regime for the ecological system, land use and efficient release of water from the reservoirs that would enhance conservation for drought situations.
