INTEGRATED APPLICATION OF (MODFLOW) AND (WEAP) MODEL IN NINEVEH PROVINCE

Abstract

The province of Nineveh is considered one of the areas that began affected by the waves of drought, so it became necessary to find additional water resources. Consequently, groundwater is considered a good candidate to bridge the gap between water supply and demand. The current study included the construction of a conceptual groundwater model, then this model is converted to a numerical model by means of (MODFLOW) and after a proper calibration of the model it was linked to a surface water model using (WEAP) tool to reduce the shortages in supply of different water requirements. It was noted that when relying on groundwater as an extra resource to the surface water resource, there is an substantial improvement in the reliabilities of meeting the various demands. Additionally, the simulation results revealed that the possibility of adding groundwater as a dependable resource is helping to meet the requirements and to substitute the future shortages of water. The main contribution of the present research is unifying the surface water system with groundwater system in such a way that could be use them interchangeably whenever it is necessary. The proposed mechanism could predict the states of supply and demand through virtual scenarios which could be of a great help in development of preparedness and proactive plans to face future challenges in issue of water supply.
