CE3035 Irrigation Engineering and Drawing Syllabus:

CE3035 Irrigation Engineering and Drawing Syllabus – Anna University Regulation 2021

COURSE OBJECTIVE:

• To expose the students to irrigation principles, concept of available water, storage and diversion structures, and canal irrigation with the design components, so that they could understand the necessity of irrigation which aims at providing water at the right quantity, at the right time and at the right place.

UNIT I IRRIGATION PRINCIPLES

Need for irrigation – Advantages and ill effects – National Water Policy – Tamil Nadu scenario – Physical properties of soil that influence soil moisture characteristics – Concept of soil water potential and its components – Concept of available water – Measurement of soil moisture content.

UNIT II CROP WATER REQUIREMENT

Necessity and importance – Crop and crop seasons in India – Duty, Delta, Base Period – Factors affecting Duty – Irrigation efficiencies – Consumptive use of water – Irrigation scheduling: CROPWAT – Standards for irrigation water.

UNIT III DIVERSION AND IMPOUNDING STRUCTURES

Diversion Head works: Components, Location, Functions – Weirs and Barrages – Types of dams – Factors affecting, location of dams – Forces acting on a dam – Spillways – Energy dissipaters.

UNIT IV CANAL IRRIGATION AND IRRIGATION WATER MANAGEMENT

Classification – Design of irrigation canals: Regime theories – Canal regulators – Canal drops – Cross drainage works – Canal Outlets – Canal Escapes – Lining of canals – Methods of Irrigation: Surface, Subsurface and Micro Irrigation – Systems of Rice Intensification – Water delivery systems – Rehabilitation – Modernization – Participatory Irrigation Management.

UNIT V DRAWING

i. Tank Surplus Weir – Design principles – Drawings showing Plan, Elevation and Sections
ii. Gravity Dam – Design principles – Profile of gravity dam
iii. Canal Drop – Design principles – Drawings showing Plan, Elevation and Sections
iv. Canal Regulator – Design principles – Drawings showing Plan, Elevation and Sections
v. Canal Aqueduct – Syphon Aqueduct (Type III) – Design principles – Drawings showing Plan, Elevation and Sections

TOTAL: (L:30 + P:30) 60 PERIODS
COURSE OUTCOMES

On completion of the course, the student is expected to be able to:
CO1 Acquire an in-deapth understanding about the National Water Policy, soil-water- plant characteristics and the measurement of soil water.
CO2 Capture the basics of crop water requirement and hence to perform irrigation scheduling.
CO3 Understand the diversion and storage structures along with its components.
CO4 Design the irrigation canal and get a knowledge about the various irrigation methods and apply the concepts for irrigation water management.
CO5 Design and draw the irrigation structure showing the detailed plan, elevation and sections.
