“…The research are focused on a large area of approximately 100,000 square kilometer, located between the latitudinal coordinates of 31°42' and 32°01'N, and the longitudinal coordinates of 44°02' and 44°25'E. The region's topographys, as shown in Fig (1), is predominantly flat with minimal changes in elevation. In recent year, there have been significant urban development in the northern part of the study area.…”

In this research, the quality of groundwater was studied for fifty wells distributed in areas near the Bahr al-Najaf depression. Where a large discrepancy was observed in the readings and concentrations of the thirteen variables that were identified, they included both the acid function pH and their ranged between (7.11 - 7.29) and the electrical conductivity EC whose values in the number of wells measured were between (2351 - 8901 μS/cm) and the total dissolved salts TDS were between (1520 to 5773 mg/L). In this study, the concentrations of positive ions were also measured, including calcium, and their values ranged between (155 to 594 mg/L), sodium (235 to 895 mg/L), potassium (2 - 101 mg/L), and magnesium (60 to 337 mg/L). Negative ions represented by sulfates SO4 2- were also studied, and their concentrations ranged between (517 to 1919 mg/L), chlorides Cl− (293 to 1243 mg/L), and nitrates NO3 − (0.3 - 1.8 mg/L). The concentrations of heavy metals in the water of these wells were also studied, and their values included lead ions (0.00 - 0.0183 mg/L), cadmium (0.00 - 0.0038 mg/L), and manganese (0.2464 - 1.1628 mg/L). Then the water quality index WQI for these wells was determined, and a large discrepancy in the results was also noted after using the geographic information system GIS when drawing maps and distributing the results on them.

Using environmental flows to inform integrated water resource management in critically water scarce regions

Environmental flows (e‐flows) assessments are a powerful mechanism for enhancing and conserving the ecosystem goods and services rivers provide while allocating water to essential human use. There is a paucity of e‐flows assessments and implementation in water scarce regions such as the Middle East, where limited freshwater resources are under extreme pressure. We conducted a first e‐flows assessment of the Mujib River, a vitally important freshwater resource for biodiversity and people in Jordan. We employed a holistic approach based on the building block method (BBM), using expert knowledge, assessment and integration of the hydrology, hydraulics, fish, macroinvertebrates, vegetation, habitat integrity and benthic diatoms of the Mujib River to perform an e‐flows determination. Several significant threats to its ecology and fresh water supply were identified. The most significant was the absence of flooding and abstraction associated with upstream impoundments, as well as reliance on over‐exploited and severely pressured groundwater‐maintained flows. Overall, this paper presents the first e‐flows assessment for the Mujib River in Jordan, a vital step towards improved water resource monitoring and management in water scarce regions, and serves to highlight the urgent global need for e‐flows to preserve our critical freshwater systems.
