Irrigation and drainage networks include the design, implementation and management of systems that optimally supply the water required by fields and green spaces and drain excess water appropriately. In the irrigation sector, key activities include the design and construction of water transmission and distribution channels, pumping stations, and flow control systems to provide timely and appropriate water for agricultural crops and green spaces. In the drainage sector, the design and construction of canals and drains in order to dispose of excess water and control the underground water level is very important. Also, managing water resources and optimizing its use is one of the other important parts of this field, which preserves soil quality, prevents salinization and flooding of lands, and increases productivity in agriculture and green space, and plays an essential role in the sustainability of water resources and agricultural production.
