Hydrological map, chart showing such hydrologic features as rivers and streams; the purpose and content of these maps vary according to the country of their origin.
The national hydrological plan, Europe's biggest water project, is set to be a big bone of contention in the long tussle between Madrid and Barcelona.
Markets create and deepen a hydrological divide, taking water from the poor to the rich, from the village to the industry.
If it fails, environmental clean-ups will no doubt continue, says Colonel Robert Carpenter, the man in charge of restoration, but they will be too small to do much more than slow the rate of decline.The whole of south Florida was once one enormous hydrological system, stretching from Orlando to Key West.
These higher temperatures might also lead to a "more vigorous hydrological cycle" with more drought in some places and more flooding in others.
One of the first water-management tasks for an organisation such as this is to map the locality and define its hydrological units, each of which is an area drained by a single stream with one inlet and one outlet.
The region encompasses 11 hydrological units, one containing 41 villages.
This exodus to warmer, dryer parts of the country has coincided with a decline in the construction of hydrological infrastructure dams, aquaducts, tunnels, pipelines and reservoirs for collecting, storing and transporting water to precisely those parched places.
More important, climate change may be changing the earth's hydrological cycle, producing more extreme floods and droughts.
But the miners perforated that protective layer with 15,000 injection wells, causing massive contamination.Today, Diamo must work night and day, pumping clean water into the ground through a line of wells to form a hydrological barrier that uses water pressure to keep the worst poisons penned in.
SCAR, a nonpolitical body, coordinates not only research activities in Antarctica itself but also, through ICSU, those Antarctic programs that relate to worldwide projects, such as the International Years of the Quiet Sun, the World Magnetic Survey, the Upper Mantle Project, the International Biological Program, and the International Hydrological Decade.
