Sensor Grid Predicts Imminent Flooding 51

Posted by kdawson
from the lifting-all-boats dept.
An anonymous reader writes, "NewScientistTech has an interesting story about a river sensor network that not only measures water depth and flow, but also forms a wireless computing grid to calculate possible flooding scenarios." From the article: "If the river's behavior starts to change, the network uses the data collected to run models and predict what will happen next. If a flood seems likely — because it is rapidly rising and moving quickly — the network can send a wireless warning containing the details... [A researcher said:] 'One end goal would be that people living in areas that flood can install these themselves. They are simple and robust enough to make that possible.'"

    Unfortunately, this will not affect the real problem, which is people continually rebuilding on extremely flood-prone land at taxpayer and insurance customer expense.

    There is a difference between: "I'm building my house here, and there is a remote chance of a flood. Would you agree to help me out and spread out the risk?" and "Between me, my father and my grandfather we've rebuilt this house 4 times due to flooding. It's terrible. Give us more money to do it again."

    I'm often accused of being a liberal, but the latter group deserve nothing from the government, and insurance companies should not be compelled to grant them policies. There has to be a "Sorry, but that just doesn't make any sense" threshold when it comes to these sorts of things. National Flood Insurance and private initiatives are a good safety net that I fully support, but they shouldn't be a replacement for common sense and responsibility.

      I know this is going to shock you... but the insurance companies are aware of that. They even plan for it. They charge people based on models of how often an area gets flooded.

      People who live in a 1 year flood plain will pay far, far more for flood insurance than people who live in a 100 year flood plain. That's A Good Thing(tm). Please don't complain about the system working, or as so many on Slashdot like to put it, "There's nothing to see here, move along."

          You must have missed the ".gov" at the end of that address or the giant FEMA logo at the top of the page. Sure the government provides flood insurance to flood-prone areas. That's the problem. The government runs that program at a loss and funds it with taxpayer money. There's a reason that no private businesses offer flood insurance to flood-prone areas; it's a huge waste of money.

        Why our government, of course; the world's biggest insurance company, and the only one dumb enough to underwrite such a policy.

        No sane insurance company would write half the policies that the National Flood Insurance Program does, because they know better. They can't just depend on a steady stream of money from nowhere to keep them afloat financially, at the same time that their insureds may be literally; companies in the real world have to at least break even ove

      Usually, it isn't so easy. We know where the floodprone areas are. We've got FIRMettes [1], flood insurance rate maps that show where the floods are known to happen, and they show the high water marks for the design flood. The problem is that the design flood occurs more frequently now. The spread of suburbia means less agricultural and sylvan land for infiltration, and very efficient storm water management systems that dump right into the river at speed. The weather over the short term seems to favor conce

      It isn't solely due to people being idiots that they live in flood planes. A large majority of shipping routes travel to, and build warehousing, in flood zones. Large scale shipping operations depend on these areas, as do other industries desiring close proximity to shipping lanes. People live in these areas not because they are stupid, but because there are jobs and important transportation infrastructure as well. So long as it is profitable to do so, people will keep going back and rebuilding. Don't

  • I was at NYLF 2003 in San Jose and intel did a presentation on some wireless sensors they were researching. They were toting that they could be tagged onto trees and alert authorities of forrest fires at the point they started. A lot of interesting uses for this technology, although I'm sure someone will be object that it could be misused to invade one's privacy.

    Oh, wait, this is Slashdot, not Fark. My bad....


    Actually, some of this is really interesting technology. A few projects along these lines have been Motes and Smart Dust at Berkeley, and at least one of the groups named their project after the Larsen Localizers from Vernor Vinge's books even though getting that small is a ways out. Gumstix is a bit bigger, so there are a few more options and a bit less work on customization required compared to the smaller devices.

    The river swale, also in the Yorkshire dales, used to have a water level up the dale at Muker which rang a bell in Richmond police station about 40 miles downstream so that the police could come out and clear the tourists picnicing on the river banks when there was a cloud burst up on the tops and the sun was still shining in Richmond and the river was about to rapidly rise.

    Reading the article I wonder whether this vastly more complex system is really going to work when the river is in full flood and metre sized boulders are scouring out the river bed and banks. I've seen Bluetooth mice having trouble communicating in indoor conditions at a distance of 2 metres.

    Still it is not all bad - at least the sheep will get to enjoy their own WiFi connection.

      Hopefully it will either replace their predictions or help them. My mother in-law lives next to a river and they're predictions have been off by amounts that have bad results. A few feet is the difference between being safe and the first floor flooding for some people like her. More accuracy for this sort of thing is long overdue and much needed in many areas.
