Detection of the illegal use of groundwater in Hassa basin based on Remote Sensing and GIS

As a result of the great scarcity of water sources in Jordan and nearly the total dependence on groundwater which suffers from the drying up of almost all its basins, the Jordanian state decided to rate the quantities of water to farmers and make it not free, in addition, the drilling of any groundwater well must be licenced by the Ministry and equipped with a meter. Many violations occur to circumvent laws such as digging unlicensed wells or using illegal ways to obtain water for free and in the quantities they want. This study aims at how to Geomatics to monitor these encroachments and estimate their quantities in Hassa basin in southern parts of Jordan, using monthly satellite images for the budget water year 2021-2022 (from October 2021 to September 2022), after making the necessary processing and making all necessary computations of water irrigated need for the period 2021-2022. A comparison between the results of water irrigated need obtained from GIS&Remote Sensing data and the production of water wells in this basin was done to evaluate the illegal use from groundwater. As a result of this comparison, the value of irrigation requirement exceeds the value of groundwater wells water production by 3.71 million cubic meters.
