HYDROLOGY AND WATER MANAGEMENT
Introduction: Hydrology, hydrologic cycle and the hydrologic equation, practical uses of hydrology, importance of hydrology.
Meteorology: The atmosphere and its composition, relative humidity, dew point and their measurement devices. Saturation deficit. The general circulation of wind system, the monsoons and western disturbances. Measurement of air temperature, relative humidity, radiation, sunshine,atmospheric pressure and wind velocity & direction.
Precipitation: Types of precipitation, factors necessary for the formation of precipitation, measurement of precipitation, interpretation of precipitation data, computation of average rainfall over a basin.
Evaporation and Transpiration: Factors affecting evaporation, measurement of evaporation, evapo-transpiration.
Stream Flow: Water Stage and its measurement, selection of site for stage recorder, selection of control and metering section, methods of measurement of stream flow, interpretation of stream flow data.
Runoff & Hydrographs: Factors affecting runoff, estimating the volume of storm runoff. Characteristic of Hydrograph, components of a hydrograph, hydrograph separation, estimating the volume of direct runoff, introduction to unit hydrograph concept, S-curve, Application of probability in determining maxima/minima of discharge. Types of histogram and distribution.
Stream Flow Routing: Introduction to floods and its causes, frequency and duration analysis. Reservoir routing, channel routing. Flood Control.
Groundwater: Introduction, sources and discharge of ground water. Water table and artesian aquifer, ground hydraulics, pumping test.
Water Management: Water management practices at basin level, canal level and farm level.
