Document Summary

Lecture 6: water cycle and introduction to models (9/10/20) Surface terrain and watersheds surface terrain does not always match actual water flow in human altered systems, topography is not the only factor controlling flow paths. John wesley powell"s recommended map of the western usa. Process by which water moves on, above, and below the surface of earth . Importance spans across scales in time and space local to global short to long term. The main factors affecting evaporation are temperature, humidity, wind speed, and solar radiation. The principal source of water vapour is the oceans, but evaporation also occurs in soils, snow, and ice. Evaporation from snow and ice, the direct conversion from solid to vapour, is known as sublimation. Evaporation evaporation of water through minute pores, or stomata, in the leaves of plants. transpiration and the evaporation from all water, soils, snow, ice, vegetation, and other surfaces are lumped together and called evapotranspiration, or total evaporation.
