Sentences with phrase «land water reservoirs»

On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water in the global ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of water between oceans and other reservoirs (glaciers and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).

What the people needed most was water for themselves, their grasslands and their crops, and canals and reservoirs were developed with much engineering skill to drain off the flood waters and irrigate the land.

That is apparently what happened to the 99 villagers of Miaohe, 10 miles (17 kilometers) upstream of the Yangtze, who saw the land behind their homes split into a 655 - foot -(200 - meter --RRB- wide crack last year, soon after the reservoir water level was lowered for the summer floods.

The new study is one of the first to provide a global accounting of regional and local water impacts, taking into account seasonal changes and different types of intervention, including water withdrawals, reservoir regulation, land - use change, and irrigation.

The drought, they found, will lead this year to 32 percent more acres of land laid fallow, an increase in groundwater pumping to make up for the lack of water in rivers and reservoirs, and total job losses of 18,600.

This strips the land of its nutrients, reduces agricultural productivity, and clogs waterways and reservoirs, thus increasing costs for purifying drinking water.

It makes land areas flood - prone, causes soil salinisation, results in the deterioration of the quality of water, silting of rivers, streams and reservoirs.

He reveals the most daunting water issues we face today, among them the threat of flooding in China's Yellow River, where rising silt levels will prevent dykes from containing floodwaters; the impoverishment of Pakistan's Sindh, a once - fertile farming valley now destroyed by the 14 million tons of salt that the much - depleted Indus deposits annually on the land but can not remove; the disappearing Colorado River, whose reservoirs were once the lifeblood of seven states but which could dry up as soon as 2007; and the poisoned springs of Palestine and the Jordan River, where Israeli control of the water supply has only fed conflict between Israelis and Palestinians.

• Next, we build out pumped hydro for storage, using available bodies of water for the lower reservoir, and turkey - nest dams on flat, elevated land for the upper.

land - use change, deforestation, dams, reservoirs, other effects of urbanisation, other hydraulic influences such as regulated water releases, changing channel capacity and / or implementation of flood prevention measures.

New York City has great quality tap water because the city invested in water protection by purchasing land around its Catskills reservoirs to ensure that polluted runoff from roads and lawns doesn't enter the water supply.The city's $ 600 million investment in Catskills land protection and restoration did the job of $ 6 billion in capital costs to construct a water filtration plant as well as $ 200 - 300 million in annual operation and maintenance costs.

But these large reservoirs of heat warm the air over them, that warm air and water vapor is then transported over land, which adds to surface temps.

These odd manipulations (along with added «corrections» to * actual * sea level based on water reservoirs on land, while ignoring ground water pumping) resulted in a sea level curve that shows a recent upswing:

Land subsidence, a phenomenon in which the land surface sinks, is sometimes caused by the removal of water from geothermal reservoLand subsidence, a phenomenon in which the land surface sinks, is sometimes caused by the removal of water from geothermal reservoland surface sinks, is sometimes caused by the removal of water from geothermal reservoirs.

Most geothermal plants re-inject water into the reservoir after it has been used to prevent contamination and land subsidence (see Land Use belland subsidence (see Land Use belLand Use below).

to be used for drinking water Less evaporation from the storage reservoir Little loss of land No damage due to dam failure Pollutants such as mosquitoes and snails can not exist in the reservoirs Siltation does not create any problems Less vulnerable / below the ground surface in a shallow soil toward the impervious crystalline sub soil.

He got his acceleration via adjustment to * actual * sea levels to account for land based water reservoirs while ignoring ground water pumping to the surface.

These partially offsetting effects lead to the expectation that direct human shifts in water storage on land will not have large effects on sea level in comparison to the effects of ocean warming and mountain - glacier and ice - sheet melting (Wada et al., 2012), although notable uncertainties remain in regards to future groundwater use and reservoir construction, and these effects vary considerably depending on the specific location (NRC, 2012e).

Comparison between seasonal pumped - storage and conventional reservoir dams from the water, energy and land nexus perspective.

Make the land more robust to drought, and you have less of a tyranny of drought fears among operators of water reservoirs.

The area of land surveyed is the most heavily irrigated in the world, with 50 - 75 % or more of land equipped with irrigation from groundwater or reservoir water.

A short list of the areas where development is prohibited includes: areas adjacent to ground and surface water reservoirs and tributaries; mature forests; wildlife habitat; connecting zones; areas containing gravel, sand or limestone; and — just in case anything was missed by that wide net — areas where agricultural land predominates.
