The Lachine Rapids are a series of rapids on the Saint Lawrence River, between the Island of Montreal and the south shore. They are located near the former city of Lachine. The Lachine Rapids contain large standing waves because the water volume and current do not change with respect to the permanent features in the riverbed, namely its shelf-like drops. Seasonal variation in the water flow does not change the position of the waves, although it does change their size and shape. The rapids are about 3 miles (4.8 km) in length. In the past these represented a considerable barrier to maritime traffic. Until the construction of the Lachine Canal through Montreal, the rapids had to be portaged. Even with the canal, the difficulty was such that it was usually more convenient to ship goods by rail to Montreal, where they could be loaded at the city's port. Montreal remains a major rail hub and one of Canada's largest ports for that reason.
The Lachine Rapids are now passed by the South Shore Canal (Saint-Lambert and Côte Sainte-Catherine locks) of the Saint Lawrence Seaway.
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a run (a smoothly flowing part of a stream) and a cascade. Rapids are characterised by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white colour, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length.
Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While class I rapids are easy to negotiate and require no maneuvering, class VI rapids pose threat to life with little or no chance for rescue.
Rapids! were an indie rock band from Bournemouth, England, which formed in August 2009.
Rapids! held their debut gig in a small bar in Bournemouth in October 2009. They released their first three track, self-titled EP in November 2009, limited to 200 copies and containing their earliest songs: "Maps", "Void" and "The Elitist". Following further time in the studio, they released a six track EP in March 2010, building on their first three tracks with the songs "Fuses", "Economics" and "Inland Empire".
Between October 2009 and early 2010, Rapids! played a large number of shows across the south coast of England, gaining favourable reviews in Artrocker and Rocksound, as well as having airplay on John Kennedy’s XFM show. The band signed to the London based record label, Heist Or Hit Records, in July 2009.
In summer 2010, a year after forming, Rapids! built on the earlier XFM radio play with the track "Fuses" being played by Tom Robinson. Steve Lamacq invited the band on to his show for a live interview and radio play. In September 2010, Rapids! played a live session for BBC Introducing on BBC 6 Music.
The Real-Time Automated Personnel Identification System (RAPIDS) is a United States Department of Defense (DoD) system used to issue the definitive credential within DoD. RAPIDS uses information stored in the DoD Defense Enrollment and Eligibility Reporting System (DEERS) when providing these credentials. Used together, these two systems are commonly referred to as a DEERS/RAPIDS system or DEERS/RAPIDS infrastructure.
RAPIDS performs the following functions:
These objectives are explained further below.
RAPIDS ensures that DoD identification credentials are provided only to personnel with a current and appropriate affiliation with the DoD
RAPIDS captures identifying characteristics that are unique and are used to bind an individual to the information maintained in DEERS and in line with the identifying credentials issued by RAPIDS. These include, but are not limited to:
