ABSTRACT The rate of groundwater extraction is increasing due to population growth. Balancing pumping rates with natural recharge necessary for sustainable use. safe was determined using the model ModelMuse. To determine rate, 39 borehole data points were gathered and adjusted 4, 8, 12 h scenarios 50 years in a steady-state condition. study area calculated four empirical approaches addition water balance method. Of methods, technique provided most accurate estimates recharge, an estimated average 176.75 mm per year. ModelMuse report demonstrated that there positive storage all boreholes be pumped simultaneously under 4- 8-h scenarios, but would significant drawdown 12-h from stress period 2039–2065, summation inflow outflow become negative, indicating withdrawal greater than rate. Thus, Borkena 975 L/s scenarios.

Studying groundwater renewal time is a valuable tool to deepen the comprehension of sustainable resources specific arid regions. Tritium radioactive isotope hydrogen often used as an environmental tracer study time. The present work reports times by tritium understand water in First, samples were collected from wells northeastern regions Saudi Arabia. Then, electrolysis process was employed significantly increase level twenty-five thirty original concentration. Subsequently, enriched analyzed using liquid scintillation counter under optimized measurement conditions determine concentration precisely. Two internationally recognized laboratories conducted independent assessments validate estimated levels. verified then estimate Morgenstern and Pimenta curves. results suggest that most monitored surveyed areas are more than century old. Conversely, few monitoring exhibit several hundred years may be considered nonrenewable sources. These studies help geochemical characteristics ensure management protection resources.
