**2. General Characteristics of Study Area**

The primordial settlements in Abu Dhabi traced to 7000 years ago and elsewhere are regarded as from the late stone age [29]. Agricultural hubs were established by the semi-nomadic peoples at Al Ain and Liwa regions [30]. It is an elapsed statistic that most of the populace endured on sustainable water management, attributed to rough climatic conditions that prevailed then. Stringent punishments were levied on anyone who accidentally or purposely threatened the water resources. The Liwa desert accommodates high temperatures ranging from 40 to 50 ◦C [31]. We can witness the highest dunes southwards of the Liwa crescent, prevalently known as the Moreeb dune [32]. Though dry scape appears on the surface, dunes can aid in excellent groundwater recharge with whatever rainfall is available over this zone. In the northern side of Liwa, i.e., Madinat Zayed, we can witness fresh water under the dunes [33].
