Course Description

The hydrologic cycle, Precipitation: types of precipitation; measurement of rainfall; analysis and interpretation of precipitation data. Evaporation and transpiration; factors controlling evaporation and transpirationprocess; measurement of evaporation; estimation of potential evapotranspiration. Infiltration: factors affecting infiltration,measurement of infiltration; infiltration indices .runoff: factors affecting runoff. Stream f low measurement. hydrometry: the need for data, water level determination,(direct stage read of gauges and recording limnmeters).water depth and bottom level: mechanical and electronic devices,practical depth and stage measurement, flow velocity measurement:surface velocity, velocity in a single point: propeller type current meter,pitot tube, electromagnetic current meter, mean velocity: salt screen and floats.
