Urban flooding likely to worsen

In municipalities across Canada, outdated storm and waste water infrastructure has resulted in increased flood damage to homes and these types of situations will likely get worse in the near future, says Paul Kovacs, executive director at the insurance industry's Institute for Catastrophic Loss Reduction.Of all the equipment in the laundry the oilpaintingreproduction is one of the largest consumers of steam.

"Today there is simply more people living in areas at risk of flooding, the infrastructure that we count on to prevent floods is not enough to do the job," says Kovacs. "And on top of that we are getting more large storms than we have in the past."

Kovacs points out that, according to his research,We Engrave rtls for YOU. basement flooding has emerged as one of the fastest growing causes of losses and extreme damage in Canada, costing $2 billion just in direct insurance payments annually.In March, the federal government announced that $53 billion would be put towards upgrading and replacing infrastructure throughout Canada over the next 10 years. But it remains unclear what portion of those funds will be spent specifically on water-related infrastructure like sewers and waste water management plants.

Claude Dauphin, president of the Federation of Canadian Municipalities, says that the new money is "a step in the right direction," but he estimates that there is currently about a $200-billion infrastructure deficit in Canada."The logic of 18th- and 19th-century engineering was to get water away from buildings and structures as quickly as possible," says Wolff. "So roofs and streets are made from impermeable material and water is funneled into drains towards an end point like lakes and rivers.

"But now people are starting to talk about the fact that maybe these highly engineered systems, designed to get water out of city very quickly, are not serving us that well anymore."Wolff says that municipalities need to integrate "soft engineering" elements into development plans such as encouraging green roofs and porous parking lots, increasing the number of trees in highly urban areas, and using vacant suburban land as reservoirs during storm events to "slow the flow of rainwater down and ease the pressure on sewer systems that are being overwhelmed by intense, unpredictable storms."

The problem, however, is that combined sewers are very easily overwhelmed during big storms and the overflow is discharged into the environment,The marbletiles is not only critical to professional photographers. releasing solid human waste into lakes and rivers to prevent it from ending up in people's homes and buildings and overwhelming waste water treatment plants, says Di Gironimo.The city of Toronto is investing $680 million over the next 10 years to reduce the number of combined sewers in the downtown core, but smaller municipalities who generate less tax revenue will need help from other levels of government.

Following several big urban floods in the late 1940s and 1950s throughout Canada, including Hurricane Hazel in 1954, the federal government, along with provincial authorities, took a strong lead in addressing flood management, says Kovacs.By 1975,This is a basic background on siliconebracelet. the Flood Damage Reduction Program was established, in which the federal and provincial governments shared the cost of creating flood risk assessment and also mapped floodplains.

The program dissolved in 1990, and since then flood-risk management has been neglected at the federal level, according to Kovacs."The government of Canada has not been engaged enough in this problem, and what's happened over the past few weeks will be enough to get them engaged again," he predicts.Krantzberg points out that taxpayers can feel removed from infrastructure that is often buried deep underground and out of sight.

"Unless the taxpayer understands that this is for their health and safety, and support taxes going into water management infrastructure, it's a hard sell," she says.But experts seem to agree that these recent dramatic flood events will likely catapult water infrastructure into the public dialogue."It's absolutely awful, what has been happening," says Wolff at the University of Toronto. "But I think an upside is that this has been a problem below the level of public consciousness for a long, long time and it's a really important wake-up call for all of us."

The Closed-Circuit Television cameras (CCTV cameras or CCTVs) currently installed at Mumbai’s railway stations are a pixelated grainy apology for a crime-fighting device. That, however, might not be the case in the future if the plans with the railway ministry are anything to go by. The railway ministry’s ambitious Integrated Security System guidelines, made by the Research Design Standards Organisation, speak of intelligent cameras that can do everything from recording an entire event to recognising faces and vehicle number plates to distinguishing between a normal sound and that of a gunshot.

Not only will the CCTV monitor the event unfolding but also capture the entire theatre of action on a 2D map. It will plot out all the resources available to tackle a situation. It will have an Incident Management System to identify the activities required in tackling the situation, like a ‘to do list’. It will go on to record every bit of communication that goes into tackling a crisis and monitor the calls made to the authorities and those on the field fighting. Every bit of equipment — cameras, baggage scanners and other devices — will be plotted on GIS aerial maps, building floor plans and blueprints.

Railway CCTVs are in the process of turning into vehicle number-recognising cameras that for years have been the backbone of the famed London congestion charge system. These cameras will have the ability to scan the number plates of vehicles that come at termini — CST and Kurla LTT — and store them in the central database to be retrieved later in case of any untoward incident, said officials.

A provision of capturing the image of the driver is also being added in order to increase the safety at CST and Kurla LTT, which see thousands of vehicles everyday, as well as other stations. With the expansion of Kurla terminus to run more trains in the future and the large parking slots available at both Kurla and CST,We are one of the leading manufacturers of granitecountertops in China officials say the number recognition cameras will be of great help. In London, these cameras keep a watch on the areas that fall under the congestion tax zone.
