Rainwater harvesting & aquifer recharge techniques must in arid regions of Egypt: Study
[...]
A new study highlighted that using storage dams and recharge wells effectively captures rainfall and prevents loss of evaporation or runoff into the sea. This approach enhances aquifer recharge and improves groundwater sustainability, especially during drought periods.
Integrated Water Resource Management, combined with techniques like rainwater harvesting and managed aquifer recharge, collectively known as RWH-MAR, becomes a sustainable and reliable solution for arid and semi-arid regions, according to the report published in Springer Nature journal.
The study was carried out in the desert of El Qaa Plain, which is the largest groundwater aquifer in Sinai, Egypt. The area is suitable for carrying out the RWH-MAR techniques.
It demonstrated the potential benefits of the RWH-MAR system for the El Qaa Plain by modelling groundwater using technologies such as the Watershed Modeling System and the SEAWAT software. The former mainly carries out the hydrologic and hydraulic modelling of a watershed and the latter helps to simulate how harvested rainwater can flow into the groundwater and improve aquifer recharge.
