Future water supply and demand assessment in peri-urban catchments using system dynamics approach

Abstract

Having effective modeling tools at the disposal of catchment managers and planners are essential to developing more effective future water management strategies. The actual projections of the demand and supply are often very dependent and interrelated with many variables, including each other for most catchments. The traditional approach used by water managers, whereby the demand based on population increase trend and water availability (supply) forecasts are calculated separately, is limited in its use due to this restriction. This is most noticed through the lack of consideration of the dynamic interrelationships that can occur between the supply and demand sides of water. This is where Sy..
