Simulation for Groundwater Demand and Consumption in Khartoum State

Abstract

Abstract-This paper is based on simulation for groundwater demand and consumption system which needs heavy investigation efforts and takes long time by using traditional methods to analyze the rates of water demand and consumption. The main purpose of this paper is to estimate the water demand on the basis of population growth in Khartoum state for the coming years so as to fulfill the population needs for water. Information about water consumption and population increase has been covered, with emphasis on the problems of caused by lack of water. All methods in respect to simulation has been taken into consideration, illustrating various models with related definitions and taxonomy as well as various techniques of estimating future consumption of water and prediction for future population. Finally, the study reveals that the existing groundwater with the recharge from the Nile which was estimated to be about 100 million cubic meters per year can not suffice the population demand for water for the coming years in Khartoum state if they depend only on the groundwater. After 35 years from the simulation study year, the population demand will exceed the existing groundwater.Index Terms-VIN, the water left over in the groundwater basin at the end of the last year, VOL, the total volume, DEM, demand, diff, difference, VNET, the total volume net.
