|Engineering Hydrology||Learning Schedule|
Hydrology is a subjects which deals with Evaporation, Condensation and Precipitation of water on the earth surface and is known as hydrologic cycle. It is a study of surface and surface flow & study of under-ground water. It is study of rainfall, runoff, flood along with imparting knowledge of flood routing for irrigation projects.
- To provide knowledge to students regarding occurrence of rainfall, storage of water, estimation of flood.
- The students shall learn about ground water permeability and transmissibility and yield of water from well.
On completion of this course, the students will be able to
- The students shall learn to estimate rainfall and perform hydrograph analysis.
- Extract maximum amount of water from around aquifers after locating them.
- Perform calculation for flood routing for various irrigation projects.
Hydrologic cycle, scope and application of hydrology to engineering problems, drainage basins and its characteristics, stream geometry, hypsometric curves.
Unit II: Runoff
Types & forms of precipitation, rainfall measurements, interpretation of rainfall data. Missing rain fall data, Runoff, runoff cycle, infiltration indices, Hydrograph analysis, Module hydrograph, applications. Time Series Analysis.
Unit III: Evaporation, Trasnpiration and Infiltration
Evaporation Process: Process, evaporimeters and empirical relationships, analytical method, reservoir evaporation and methods of its control.
Transpiration Process: Evapo-transpiration and its measurement, Penman`s equation and potential evapo-transpiration.
Infiltration Process: Infiltration process, initial loss, infiltration capacity and measurement of infiltration, infiltration indices.
Unit IV: Ground Water Hydrology
Ground water-Aquifers, Permeability & transmissibility- steady flow towards a well in confined & water table aquifer-Dupits & Theims equation – measurement of yield of an open well – Tube well & infiltration gallaries. Interference among wells-well losses, comparison of well and flow irrigation.
Unit V: Flood Routing
Introduction to flood routing and its importance for the construction of hydraulic reservoirs. Hydrologic routing and hydraulic routing. Methods of flood routing- Step by step method, trial and error method.
