Hydrologic cycle

Published on

Hydrologic Cycle is also called as Water Cycle. It basically deals with transformation of water in different forms starting from gaseous stage (water vapor) to liquid state (water on earth's surface), and water inside soil as underground water.and again back to gaseous stage. The cycle has no starting or end.

  1. 1. By – N.G.Palit Hydrologic Cycle
  2. 2. Hydrologic Cycle
  3. 3. This is about the movement of water on Earth  Hydrologic Cycle is also called Water Cycle. It deals with the origin and distribution of water on the globe.  Complex pathways include passage of water from gaseous stage in the atmosphere to oceans, lakes, rivers etc.
  4. 4. Hydorlogical Process  Hydrological cycle includes the following processes: evaporation, condensation, precipitation, interception, infiltration, percolation, transportation, runoff and storage.
  5. 5. Evaporation  Evaporation occurs when water changes from liquid state to gaseous state.  Evaporation occurs on water surfaces like lakes, seas etc. Evaporated moisture is lifted into atmosphere. But, some vapor always exists in the atmosphere.
  6. 6. Condensation  Condensation is the process by which water vapor changes into water.  Water vapor condenses to form dew, fog or clouds.  Condensation takes place due to cooling of air.
  7. 7. Precipitation  Precipitation is the process that occurs when water particles fall from the atmosphere and reach the ground.  Precipitated water may fall into water bodies or on land. It can then go to streams or penetrate into the soil.
  8. 8. Interception  Interception is the process of interrupting the movement of water in the chain of transportation events leading to streams.  When rain first begins, water striking the leaves and other materials spreads over the surface or collects at points of edges.
  9. 9. Infiltration  Infiltration is the physical process involving movement of water through the boundary area where atmosphere interfaces with the soil.  Infiltrated water and water stored in the soil, can become subsurface runoff.
  10. 10. Percolation  Percolation is the movement of water through the soil, due to Gravity and by capillary forces.  All ground water originates as subsurface water.
  11. 11. Transpiration  Transpiration is the biological process that occurs mostly in the day.  Water inside plants is transferred to the atmosphere as water vapor. Only a small portion of water is retained by the plants.
  12. 12. Runoff  Runoff is a flow from a drainage basin in surface streams.  It generally consists of the flow that is unaffected by artificial diversions or storages.
  13. 13. Storage  There are three basic water storage places: in atmosphere, on earth’s surface, and in the ground.  Surface storage places are: ocean, lake, reservoirs, glaciers.  Underground storage occurs in soil, in the cracks of rocks etc.
  14. 14. Floods & Droughts  Uneven distribution and movement of water can cause extreme phenomena such as Floods and Droughts.
