4-0-0-4

2016

Prerequisite : CE309 Water Resources Engineering

Course objectives:

·       To impart knowledge regarding the design of the various minor irrigation structures

·       To convey the knowledge on the causes of failure, design criteria and stability analysis of different types of dams

Syllabus :

Diversion head works – layout and functions of components. Causes of failure of weirs on  permeable soils, Bligh’s theory and Khosla’s theory. Irrigation canals- Design of unlined canals through alluvial soils-Kennedy’s theory and Lacey’s theory. Minor irrigation structures- Cross drainage works, Canal Regulation works : Falls and Regulators, Design of Hydraulic Structures: Aqueduct, siphon aqueduct, Canal falls-notch type, well type, Sarda type, and Cross regulator. Dams-Types, Gravity dam – forces acting – stability analysis and modes of failure – theoretical and practical profiles- Functions of shafts, galleries, keys and water stops. Arch dams-types, Thin cylinder theory. Earth dams-types, causes of failure and design criteria. Spillways-Types. Ogee type

spillway-profile.

Course Outcomes:

The students will be able to

i.                Perform the stability analysis of gravity dams

ii.                Explain the causes of failure of different types of dams and their design criteria

iii.           Design minor irrigation structures such as regulators, cross drainage works and canal falls
