Upon completion of the course the student shall be able to

1. Aware of necessity and scope of Irrigation Engineering, Hydrology, calculation of average annual rainfall of an area and maximum flood discharge
2. Enable to gain knowledge about Storage and diversion Head Works, component parts, effect of percolation, Gravity dams and Earthen dams -failures of these dams and remedial measures.
3. Know about the Distribution works, maintenance of canals, uses of Cross drainage works, causes, effects and prevention of Soil erosion, Water logging, types and uses of river training works, Systems of Water management and Watershed Management.

Nature and Scope of Irrigation Engineering

Definitions- Necessity of irrigation – Advantages and disadvantages – Perennial and Inundation irrigation – Flow and Lift irrigation-Direct and Storage irrigation. Principal crops – Kharif and Rabi crops -Dry and wet crops – Definition of duty, delta, base period, and crop period, Duty-different methods of expressing duty-base periodrelationship between duty and delta- factors affecting duty – Requirements for precise statement of duty – Duty figures for principal crops-simple problems on duty.

Head Works

Classification of head works – Storage and diversion, head works – their suitability under different conditions – Suitable site for diversion works – General layout of diversion worksbrief description of component parts of diversion works, brief description of component parts of a weir – Barrages and Weirs. Head Regulator-scouring sluice-flood banks and other protective works. Percolation -Percolation gradient-uplift pressures – Effect of percolation on irrigation works.

Gravity Dams and Earth Dams

Dams – Rigid and non-rigid dams – main gravity dams-failures of gravity dams and remedial measures – elementary profile – limiting height of dam – low dam and high dam – free board and top width – Practical profiles of low dam – uplift pressure – drainage gallery -Contraction joints – Grouting of foundations – spillways Earth dams – situations suitable for Earth Dams – Types of earth dams – Causes of failure of earth dams and precautions – Saturation gradient and phreatic line-drainage arrangements – Construction details of earth dams – breaching sections – breach filling – Maintenance of earth dams.

Distribution Works

Canals-classification-different methods of canal alignment-typical cross section of canal in cutting, embankment, partial cutting and embankment – Berms – standard dimensions -balancing depth of cutting – canal lining – Necessity – types – Maintenance of canals. Laceys regime Silt Theory and Kennedys Silt Theory (only explanation of formulae)-Comparison of two theories (No problems) Cross drainage works – Necessity – General description of aqueducts – Super passage -Under tunnel – siphon level crossing- Inlet and outlet.

Soil Erosion, Water Logging and River Training Works
