Prerequisite
Knowledge of Fluid Mechanics, Hydrology and Water Resources Engineering
Rationale
To develop understanding about water requirement of crops, irrigation methods, and irrigation engineering works like weir/barrage, storage and outlet works, distribution works, regulating and cross drainage works and importance of drainage in irrigated areas.
Course Outcome
After learning the course the students should be able to:
1. Understand the irrigation methods and duty-delta relation for crops
2. Calculate Net Irrigation Requirement (NIR), Field Irrigation Requirement (FIR) and Gross Irrigation Requirement (GIR)
3. Calculate the pressure at key points of sheet piles and floor thickness for a weir/barrage using Khosla’s theory
4. Plot seepage line of earthen dam with corrections at entry and exit
5. Calculate forces on gravity dam.
6. Understand function of spillway and energy dissipation
7. Design unlined canal using silt theories
8. Design a lined irrigation canal
9. Understand functions of regulating and cross drainage works
10. Understand drainage principles

Active Learning
Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should be submitted to GTU
