Hydrology of the most ancient water harvesting schemes

The Middle East area and in particular Jordan suffer from water shortages. It is believed that water harvesting techniques can solve part of the problem. Jawa and Umm El-Jimal water harvesting schemes were established 6000 and 2000 years ago respectively. They are considered as the most ancient water harvesting scheme. The engineering design and techniques used in those schemes are very unique.The adaptation of the engineering techniques used in the ancient schemes in the newly established schemes will help to save energy and minimize the evaporation losses. In addition, harvested water can be used for ground water recharge.<p>Validerad; 2013; 20130325 (nadhir)
