    - I conducted research on soil erosion intensity and peak discharge analysis from a water sustainable management perspective in the El Makhazine Basin, Rif, Morocco. - This study is essential for sustainable water resource management, flood protection, and agricultural productivity. By identifying erosion-prone areas and implementing control measures, such as vegetation cover, erosion control structures, and proper land use practices, the study helps prevent sedimentation, protect downstream cities from flooding, and maintain the basin's water storage capacity. Additionally, it supports sustainable irrigation practices, preserving soil fertility and ensuring the long-term resilience of the region's agriculture and communities. - Climate Change, Intensity of Erosion and Outflow (IntErO), ArcGIS, Hydro-geology https://www.geasci.org/page.php?id=163

  • Visiting Student at RADEEF

    - I took a comprehensive tour of the Station d'Épuration des Eaux Usées de Fès to gain a practical understanding of all the water purification processes. The station manages water purification and recycling for the region. - I documented all my observations and created a documentary video detailing the processes I observed. - I visited the Station de Déchromatation des Tanneries de Dokkarat in Fès, documented all my observations, and created a montage of the visit.

    - Using the Sequencing Batch Reactor (SBR) method, I conducted research on treating wastewater contaminated with hydrocarbons - I produced a comprehensive report on my laboratory research and defended my findings before a panel of four professors - The study revealed that the SBR-based treatment plant significantly reduced the objectionable physiochemical properties of wastewater prior to its discharge into a water body. However, the minimal reduction in orthophosphate, total suspended solids, and total dissolved solids remains a concern. There is a possibility of adverse effects from the effluent discharge on the receiving water body, which is already under pollution stress. Therefore, a continuous monitoring program by the relevant authorities is necessary to ensure best practices and measures are followed in the treatment and discharge of wastewater into the receiving lake system.
