Harvesting Rainwater and the Possibility of Investing in the Al-Alia Basin in the Iraqi Jazira desert

Abstract

The study found a limited possibility of applying a water harvesting system in the region, based on geological, topographical and hydrological criteria, and by selecting the proposed optimal reservoir site for water harvesting for the purpose of storing water and benefiting from it in periods of drought for the development of agricultural lands and the cultivation of wheat crops through this harvesting and working on the use of a system Sprinklers (Dim cultivation), and determined the amount of water that can be stored in the optimal reservoir by about (1176000000 m3), and these results that were reached help in the future when applied to the development of the region in several aspects such as developing agricultural lands and expanding pastures, by highlighting the role of water harvesting as a means to compensate The shortage of water and the provision of an additional source for it is used in supplementary irrigation, during the decline in the amounts of rain or drought, in addition to its use in increasing the stock of groundwater by retaining rainwater and torrents passing through the depressions in the form of lakes and barriers that are characterized by ideal storage conditions and water retention before entering the areas of cracks and faults.
