Tidal forces are stronger nearer the centre of the galaxy, increasing the rate of disruption of clusters, and also the giant molecular clouds which cause the disruption of clusters are concentrated towards the inner regions of the galaxy, so clusters in the inner regions of the galaxy tend to get dispersed at a younger age than their counterparts in the outer regions.

Tidal perturbations of large disks may result in the formation of massive planets and brown dwarfs, producing companions at distances of 100 AU or more from the host star.

The Boardwalk at HersheyparkThe newest themed area of the park, the Boardwalk waterpark was officially opened in 2007 and featured five new waterpark attractions along with three already standing rides: Roller Soaker, Tidal Force and Canyon River Rapids.

One was on the Anacostia River at the end of East Capitol Street ; one at Lincoln Park ; one on the south side of the National Mall across from the National Archives ; and one situated on the Tidal Basin, directly south of the White House.

The River Hull Tidal Surge Barrier at the mouth of the river can be used to prevent surge tides overwhelming the flood defences.

The UK National Tidal and Sea Level Facility ( NTSLF ) maintains a tidal observatory at Newlyn, and the UK Fundamental Benchmark is maintained there.

Tidal fluctuations in the main body of Cook Inlet, while not as extreme as the shallow and narrow Turnagain Arm, regularly reach and exhibit currents in excess of at full tidal flow.

The land on which the park is located is sometimes described as a peninsula but is actually an island: the Washington Channel connects with the Tidal Basin north of the park and the Jefferson Memorial.

Another environmental concern is a significant drop in Lake Sevan's water level because of drawdowns for irrigation and the diversion of water to hydroelectric plants to compensate for the electric power lost through the inactivity of the nuclear plant at Metsamor.

Sometimes they are also outfitted with irrigation systems or heat sink-systems which can respectively irrigate the plants or help to store energy from the sun and redistribute it at night ( when the greenhouses starts to cool down ).

The Indus Valley Civilization, Ancient India, ( circa 2600 BC ) had sophisticated irrigation and storage systems developed, including the reservoirs built at Girnar in 3000 BC.

By use of a pulsed irrigation timer, existing overhead sprinklers may be used to deliver water at a low average precipitation rate ranging from 2. 5 to 5ml / Hour for frosts down to-5deg.

By contrast, larger-scale farming often involves irrigation systems, chemical fertilizers and harvesters or at least ladders, e. g. to reach up into fruit trees.

First activities were linked to irrigation and flood control, as demonstrated by traces of dykes, dams, and canals dating back to at least 2000 BCE that were found in ancient Egypt, ancient Mesopotamia and the Fertile Crescent, as well as around the early settlements of Mohenjo Daro and Harappa in the Indus valley.

" at which point the listeners outline all forms of positive aspects of the Roman occupation such as sanitation, medicine, education, wine, public order, irrigation, roads, a fresh water system, public health and peace, followed by " what have the Romans ever done for us except sanitation, medicine, education ...".

It was frequently speculated that ancient Martian civilizations had constructed irrigation works that spanned the planet in an attempt at saving their dying world.

The FAO estimates the irrigation potential of all countries in the Niger river basin at 2. 8 million hectares.

The irrigation potential was estimated at 1. 68m ha in Nigeria 0. 56m ha in Mali, and the actual irrigated area was 0. 67m ha and 0. 19m ha.

In 2005 Tom D. Dillehay and his team announced the discovery of three irrigation canals that were 5400 years old, and a possible fourth that is 6700 years old, all in the Zaña Valley in northern Peru, evidence of community activity to support improved agriculture at a much earlier date than previously believed.

In the Soviet era, the Vakhsh was dammed at several points for irrigation and electric power generation, most notably at Norak ( Nurek ), east of Dushanbe, where one of the world's highest dams forms the Nurek Reservoir.

The Dostluk dam, opened at Serakhs on the Iranian border in 2005, has increased available irrigation water and improved efficiency.

In the first millennium BC, Iranian nomads established irrigation systems along the rivers of Central Asia and built towns at Bukhoro and Samarqand.

* Transvasement-Building canals or redirecting rivers as massive attempts at irrigation in drought-prone areas.

From its origin at the Delta the canal runs some southwards through the west side of the San Joaquin Valley, providing irrigation water to farmlands along its length.

They established farms and orchards supported by small-scale irrigation projects and railroad transportation, with small town centers at Hanford, White Bluffs, and Richland.

Sophisticated irrigation and storage systems were developed by the Indus Valley Civilization in present-day Pakistan and North India, including the reservoirs at Girnar in 3000 BCE and an early canal irrigation system from circa 2600 BCE.

The International Water Management Institute has worked in India, Pakistan, Vietnam, Ghana, Ethiopia, Mexico and other countries on various projects aimed at assessing and reducing risks of wastewater irrigation.

The irrigation controller is either a mechanical ( now the " dinosaur " type ) or electrical device that signals a zone to turn on at a specific time and keeps it on for a specified amount of time.

When a zone comes on, the water flows through the lateral lines and ultimately ends up at the irrigation emitter ( drip ) or sprinkler heads.

Large diversions for irrigation below Rio Grande City reduce the river's average flow to at Brownsville and Matamoros.
