The waters of the Earth circulate from the oceans through the atmosphere to the land, from which a part is returned to the atmosphere and the residual is returned to the ocean either by streams or underground flow. The paths of water on the land include surface flow to stream channels, infiltration to the soil, movement through the ground to a ground-water body and thence to a stream channel, and eventual return to the ocean. Water is extracted and returned t the atmosphere by evapotranspiration (evaporation and transpiration) throughout much of the land phase.
Figures & Tables
Provides reviews of all major facets of hydrology. Topics covered include: influences of the atmosphere and of land and vegetation on stream flow; temporal and spatial variability of stream flow, with separate chapters on floods and on low flow and hydrologic drought; snow and ice, the frozen components of the hydrosphere; the hydrology of lakes and wetlands; hydrogeochemistry of rivers and lakes; the aquatic biota; sediment movement and storage; the riverscape for selected North American rivers; and the influence of Man on hydrologic systems. Accompanying color plates show histograms of river water chemistry, runoff and flow regimes, and the distribution of precipitation minus evaporation for North America.
