The objective of this study is to document and study the hydraulic system at Al Kharj and Aflaj. These regions have a rich history of water management and irrigation systems, making them intriguing subjects for research. The study aims to gather comprehensive information about the hydraulic infrastructure, including canals, channels, wells, and water distribution structures. By conducting site visits, collecting data, and engaging with local experts and community members, we seek to understand the layout, design, and functioning of these systems. Additionally, we will analyze factors such as water flow rates and quality to gain insights into the effectiveness and sustainability of the hydraulic system.
