Academic Year: 2025-26 Semester: 4th Category of the Course: Professional Elective - I Prerequisite: Basic knowledge of fluid mechanics, surveying, soil mechanics, and mathematics. Rationale: 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. Course Outcome: After Completion of the Course, the Student will able to: No Course Outcomes 01 Recall and explain the fundamental concepts and scope of irrigation. Understand and recall the water requirements of crops and the basic soil–water– 02 plant relationships. Apply, analyze, and recall knowledge of different irrigation systems and methods 03 to solve practical problems. 04 Analyze and interpret the planning and design aspects of dams and reservoirs. 05 Demonstrate understanding, recall, and application of canals, regulating works, and cross-drainage structures. Identify water logging problems and propose appropriate reclamation and drainage measures. *Revised Bloom’s Taxonomy (RBT) 06 w.e.f. 2025-26 http://syllabus.gtu.ac.in/ RBT Level R&U R, U & A R, U & A U&A R, U & A U&A Page 1 of 6 GUJARAT TECHNOLOGICAL UNIVERSITY Program Name: Diploma Engineering Level: Diploma Branch: Civil Engineering Subject Code : DI04006061 Course / Subject Name: Irrigation Engineering Teaching and Examination Scheme: Total Teaching Scheme Credits (in Hours) L+T+ (PR/2) Assessment Pattern and Marks Theory L T PR C 03 00 02 04 Tutorial / Practical ESE (E) PA (M) PA (I) ESE (V) 70 30 20 30 Total Marks 150 Course Content: Unit No. 1 2 3 4 5 Content Introduction to Irrigation Definition, Necessity of Irrigation, Scope, Advantages and Disadvantages, purpose of irrigation, Historical development of irrigation in India, Classification of Irrigation Projects, Assessment of charges for irrigation water Water Requirement of Crops Principal Indian crops and their water requirements, cropping seasons in India, Basic Soil-water-plant relationship, frequency of irrigation, Irrigation Efficiency, factors affecting consumptive use of water, Command Areas, Definitions: Duty, Delta, Base Period and relation between them.
