INTERNATIONAL WATER MODEL UNDER PRODUCTIVITY CONDITIONS: THE CASE OF THE TIGRIS AND THE EUPHRATES

Allocation of international water resources needs to play a vital role in the shared river basins. An environmental and reliable framework involves not only the competing parties divided by geography and national boundaries but also spatially variable environmental parameters such as water productivity in agriculture. In international rivers, the inflow of turbid materials from the drainage basins of the upstream definitely affects water quality at the downstream. Consequently, emerging global challenges, such as climate change, water scarcity, and population growth have to meet rising demand over time. The Tigris and Euphrates (as a case study) give us a good example of the water system in a region politically unstable. Although a number of studies on water resources allocation modeling, such as ITETRBM and WATERModel, have analyzed the geographic nature of basins, success in achieving sustainable development calls for an optimal water allocation model. Based on water productivity conditions, and to achieve stable, long-term cooperation among riparian countries and sustainable use of the water resources, international Water Model Under Productivity Conditions (WMUPC) gives us an optimal solution. In order to show the impacts of water quality changes on downstream users, these results are presented via histogram. The significant finding, under previous conditions, is the water quantity available in downstream will be less than the quantity required.
