  1. CE- 04016 Hydraulic Engineering & its Application(Second Semester)

  2. Contents( from CE-5026 Irrigation Engineering ) 1. Chapter(3)Methods of Application of water 2. Chapter(4) Water Logging, Drainage, land reclamation and irrigation management

  3. ( from CE-4016 Hydraulic Engineering ) 3. Chapter(5)‏ • Theoretical Concepts of Boundary Layer, Surface Roughness, Velocity Distribution • 4. Chapter(6)Gradually varied flow • 5. Scale Model in Hydraulic Engineering

  4. Methods of Application of water Surface irrigation methods Subsurface irrigation methods Sprinkler irrigation Drip or trickle irrigation

  5. Surface irrigation methods • Flooding Methods • Wild or uncontrolled Flooding • Controlled Flooding • Flooding from field channels • Border strip methods • Check method • Basin method • Zig-zag method • Furrow Method • Contour Farming

  6. Waterlogging, Drainage, Land Reclamation and Irrigation Management • Causes of waterlogging • Ill Effects of Waterlogging • Measures for Prevention of Waterlogging • Drainage Systems • Surface drainage system • Subsurface drainage system

  7. Dynamic Equation of G.V.F • For Rectangular Channel

  8. Characteristics of Flow Profiles • Backwater curve • Drawdown curve • Classification of Flow Profiles • M Profiles (M1, M2, M3 )‏ • S Profiles (S1, S2, S3 )‏ • C Profiles (C1, C2, C3 )‏ • H Profiles (H1, H2, H3 )‏ • A Profiles (A1, A2, A3 )‏

  9. Analysis of Flow Profiles • Prismatic channel with constant slope • Prismatic channel with a change in slope • Prismatic channel with several changes in slope

  10. Methods of water surface profile computation • Direct step Method • Standard step Method

  11. Location of Critical Depth Control Point • For a prismatic channel

  12. Scale models in hydraulic engineering • Two different types of models: • Mathematical models can be used if the problem can be described mathematically with sufficient details. In most cases nowadays computers are used to solve these problems. • Scale models are used if the physical phenomena can be reproduced with sufficient similarity by reducing the length dimensions of the real problem area.

  13. Flow Chart for Modeling solving Model problem Model solution modeling interpretation Prototype problem Model problem

  14. Three interrelated phases • Modeling • Solving • Interpretation

  15. Calibration • Adjusting the model by means of prototype measurements. • Verification • Hindcasting of another known situation without adjusting the model anymore.

  16. Principle of scaling • The principle of the use of scale model consists of the possibility to reproduce the real problem(the “ prototype”) on a smaller scale in such a way that the phenomena in the scale model are similar in model and prototype. • Geometric similarity • Kinematic similarity • Dynamic similarity etc.

  17. The scale of a parameter is defined by the ratio between the Prototype value and the model value of this parameter.
