Title

Dynamic Analysis of Water Demand; Case Study of Qom City

Pages

  372-377

Abstract

Water Scarcity is now one of the most critical challenges in most countries around the world, and in particular in Iran. One of the key ways to control and manage this issue is to investigate water demand. Qom city has always been encountered with water shortage threat due to its location in the dry area of the country and in the absence of proper management in the near future, there will face serious hazards in this regard. The purpose of this research is the investigation of water demand dynamics in Qom city using System Dynamics method. Dynamic of various variables such as population, water demand, surface water resources, ground water, and water supply have been incorporated in VENSIM Software. The maximum relative difference of this model for estimation of water demand was found to be 7%. The change of birth rate from 4% to 2% would result in 29% reduction of water demand level in year 1405 in comparison to current trend. Base on the result, the policy of population control had the most important effect on water demand. On the other side, the effect of price on water demand is negligible, so that, 20% increase in price would lead to 2. 04% reduction in level of water demand in 1405 compared to current trend.
