About this course
Irrigation Engineering equips students with the knowledge and skills to manage water resources efficiently for agriculture and infrastructure. In addition to crop water requirements, soil-water-plant relationships, and techniques to increase irrigation efficiency, the course covers basic concepts, historical development, and types of irrigation projects. Students learn irrigation canals, regulating works, cross-drainage structures, dam and reservoir planning and design, and various irrigation systems and techniques. Hands-on understanding is improved through practical sessions that include field visits, numerical problems, layouts, and sketches. In order to prepare students to effectively analyze and resolve real-world water management challenges, the course also covers water logging and reclamation techniques.
