- 4. WHAT IS HYDROLOGY Hydrology is the science which deals with the occurrence, distributionand disposal of water on the planet earth ;it is the science which deals with the various phases of the hydrologic cycle.
- 5. WHAT IS HYDROLOGIC CYCLE? • The hydrological cycle is the system which describes and movement of water between the earth and its atmosphere. • Water cycle describes how water is exchange through earths land ocean and atmosphere. • It also describes the continuous movement of all forms of water [ vapour, liquid and solid Jon, in and above earths surface.
- 8. EVAPORATION • Evaporation is the process by which water changes from a liquid to a gas or vapour •Evaporation is an essential part of the water cycle. The sun (Solar energy) drives evaporation of water from Ocean, lakes moisture in the soil, and other sources of water. • In hydrology, evaporationand transpiration(Which involves evaporationWithin plant stomata ) are collectively termed evapotranspiration.
- 10. TRANSPIRATION Transpiration is the process by which water vapourleaves the living plant body and enters the atmosphere. It involves continous flow of water from soil in to plantand Out through stromata leaves to the atmosphere. Bascially and evaporation process.
- 11. CONDENSATION •The process of conversion of a vapourorgas to a liquid is know as Condensation .
- 12. PRECIPITATION Precipitation is any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the Earth. Precipitation is caused when a mass of warm, moist air hits a mass of cold air.Condensation causes the moisture to form droplets that become rain or crystals that become snow or ice. When these droplets or crystals become too heavy to be suspended in the atmosphere, they fall to Earth as precipitation
- 13. Several forms of precipitation • Snow – Precipitaion f white opaque grains of ice • Rain _ precipitation of liquid waterparticules in from 0of drops with dia 0.5mm Or more. • Drizzle _ Precipitation of very fine drops of water with dia 0.5mm Or less. • Hail _ Precipitation of small balls of ice with dia rangingfrom 5 -50 mm Or even more . • Sleet _ Precipitation of small pelets of transparent/ Lucent ice of dia 5mm Or less.
- 15. INFILTRATION • Infiltration is the process by which water on the ground surface enters the soil. • Infiltration rate in soil science is a measure of the rate at which soil is able to absorb rainfall or irrigation. • It is most often measured in millimetres per hour or inches pe hour. • The rate decreases as the soil becomes saturated. If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier. • The rate of infiltration can be measured using an infiltrometer.
- 17. GROUNDWATER • Groundwater is the water present beneath Earth’s surface in soil pore spaces and in the fractures of rock formations. • Groundwater is recharged from, and eventually flows to, the surface naturally: natural discharge often occurs at springs and seeps, and can form oases or wetlands. • Groundwater is absorbedby plant roots to end up as evapotranspiration from the leaves. Over time, this water keeps moving. Some to reenter the ocean, where the water cycle ends... Or where it begins.
- 18. RUNOFF • Surface runoff is water, from rain, snowmelt, or other sources, that flows overthe land surface, and is a major component of the water cycle. • Runoff is precipitation that did not get (infiltrated) absorbedintothe soil, or didnot evaporate.
- 19. IMPORTANCE OF HYDROLOGIC CYCLE • It is also involved in maintaining aquatic ecosystems. • The hydrologic cycle is an essential biogeochemical cycle on the earth for the maintenance of life. • The hydrologic cycle plays an important role in ensuring the availability of water for all living organisms, including plants, animals, humans and other living species.
- 20. • The hydrologic cycle is the greatest natural process which plays a significant role in the continuous movement of water on, above and below the surface of the Earth.
- 22. CONCLUSION • The hydrologic cycle is importantbecause it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
