Water budget during ultra-endurance exercise
Medicine & Science in Sports & Exercise, 1997We examined water gains and water losses in a group of athletes after an ultra-endurance event. Thirteen male triathletes competed in a triathlon consisting of 21 km canoeing, 97 km cycling, and 42 km running. Water loss determinations included sweat rate (940 +/- 163 g.h-1), urine output (41 +/- 38 g.h-1), and respiratory water loss (88 +/- 10 g.h-1).

Water is the foundation of all ecosystems, whether terrestrial or aquatic. In terrestrial ecosystems freshwater not only provides critical water supply for transpiration during plant photosynthesis and drinking water for animals, but also transports, redistributes and stores energy, nutrients and contaminants.

FIFE 1987 water budget analysis
Journal of Geophysical Research: Atmospheres, 1996The First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) represents one of the largest data collection campaigns to date in our endeavor to observe the hydrodynamic and thermodynamic processes occurring on the land surface of the Earth.

Water Budget and Physical Hydrology
1989Some information on the behavior of karst aquifers can be obtained from quantitative consideration of water inputs and outputs during median and base-flow regimes. The textbook version of the hydrologic cycle distributes precipitation as an input term into three components: evapotranspiration, surface runoff, and infiltration.

Water chemistry and nutrient budgets
1982The study of the chemical limnology of Lake McIlwaine spans some twenty years, and although the chemical records are not continuous throughout this period it is nevertheless reasonable to say that the chemical limnology of the lake is well known. The first studies were conducted in the early 1960s as the lake entered a mesotrophic phase and subsequent ...

In this chapter our goal is to highlight some of the many ways that urbanization affects the water budget and water cycle. A water budget describes the stores or volumes of water in the surface, subsurface and atmospheric compartments of the environment over a chosen increment of time.

Water Budget and Dissolved Load
1991The mean effective precipitation in the 50-year period between 1921 and 1970 is 698 mm/a, the mean evaporation rate 48.6%. This results in an average annual runoff of 1278x 106 m3. The mean mineralization of the river waters is 322.6 ppm after the summer period and 221.4 ppm in late winter, 250 ppm being a reliable mean.

Net radiation at the upper boundary of the planet Earth amounts to a heat gain in the tropics and a loss in higher latitudes. Redistribution of energy over the continents takes place exclusively in the atmosphere, whereas in the realm of the vast tropical oceans both atmosphere and hydrosphere cooperate in the heat export to other parts of the globe ...
