Design of Hydraulic Structures

Module 1 - Diversion head works- layout and functions of components, Weir and barrage- Causes of failure of weirs on permeable soils - Bligh’s theory. Design of vertical drop weir. Khosla’s theory of independent variables- Khosla’s corrections-Use of Khosla’s charts. Module 2 - Irrigation canals, canal alignment- cross section of unlined canals- Design of canals through alluvial soils-Kennedy’s theory and Lacey’s theory. Cross drainage works-Types, selection of suitable type, Type of aqueducts. Regulation Works - Canal falls-necessity, classification. Canal regulators- Regulator cum road bridge- Head regulators and cross regulators. Module 3 - Design and Drawing of the following hydraulic structures: 1. Aqueduct (Type III) 2. Syphon Aqueduct (Type III) 3. Canal Fall (Trapezoidal Notch type) 4. Siphon Well Drop 5. Sarda Type Fall (High Discharge only) 6. Cross Regulator (Using Khoslas Theory)
