OBJECTIVE:
To introduce the student to the concept of soil – Plant characteristics and their water
requirements. At the completion of the course the students should be able to understand the
necessity of planning an irrigation system to provide water at the right quantity and at right
time.
UNIT I IRRIGATION PRINCIPLES 10
Need for irrigation – Advantages and ill effects – Development of irrigation – National Water
Policy – Tamil Nadu scenario - Physical properties of soil that influence soil moisture
characteristics – Concept of soil water potential and its components: Gravitational, Pressure
and Osmotic- Retention of water in soils and concept of plant available water – Movement of
water into and within the soils – Measurement of soil moisture content and the matric tension
with which it its held
UNIT II IRRIGATION WATER REQUIREMENT AND CROPS 8
Soil- Water-Plant relationship - Water as a constituent of plant – Soil-Plant-Atmosphere
continuum – Terminology in plant – Water relationships (Evapotranspiration, consumptive use
and crop factor) – Critical stages of crop growth for water requirement – Analysis of crop water
demand: basic concepts and estimation
UNIT III IRRIGATION SYSTEM COMPONENTS 11
Components of irrigation network; Diversion headworks, Canal regulators, Canal drop, canal
cross drainage works, Canal outlets, - Functions of the above components – Canal lining -
Supply of irrigation water: Duty, Delta and Base period – Concepts of Kennedy’s and Lacey’s
formulae
UNIT IV FIELD TECHNIQUES 8
Field Measurements, Land leveling and drainage – Irrigation methods: relative merits and
limitations – Evaluation of irrigation methods –Irrigation water quality - Irrigablity of soils and
the irrigation related degradation of soil resource (such as water logging, salinity and sodicity)
UNIT V IRRIGATION WATER MANAGEMENT 8
Need for interdisciplinary approach – Irrigation beneficiaries - Irrigation Efficiency- Irrigation
scheduling concepts – methods of irrigation scheduling – On farm development works -
Participatory approach: farmer’s organization and turn over – Water Users Association –
Economical aspects of irrigation
UNIT VI DESIGN AND DRAWING OF IRRIGATION STRUCTURES (FOR INTERNAL
EVALUATION)
Design of Tank Surplus Weir – Tank Sluice with a Tower Head – Direct Sluice taking off from
a main canal – Canal Drop with Notch Type – Regulators across the canal – Profile of Gravity
Dam using AutoCAD – Design of Cross Drainage work: Syphon Aqueduct (Type III)
L: 45 + P: 30 TOTAL: 75 PERIODS
