Document Summary

Geo - lec 15 - water hydrology & streams. Clay minerals are the most abundant product of weathering and they are formed when. The movement of water between the ocean (hydrosphere), air (atmosphere), and land (lithosphere) * changes in volume of soil water or lake or river water. * runoff: part of precipition collected by stream flows at surface of the earth (that does not infiltrate or re-evaporate) * the hydrologic cycle is a summary of the circulation of earth"s water supply. Processes involved in the hydrologic cycle, which is powered by the sun"s energy. * precipitation, evaporation, infiltration, runoff, transpiration (evapotranspiration) can be scaled with catchment size allows for comparisons. Input 800 mm/a (total rain & snow: unit runoff concept, like precipitation in mm/a (a=year, typical values in ottawa area, evapotranspiration 350 mm/a, runoff 450 mm /a, losses = evapotranspiration, residence time = volume/flux per time. V= 106m3, input =2*106m3 a-1, residence time = 0. 5a.
