By late February, the dam operators were releasing more than 400 acre-feet per hour into the lower river—enough water to flood 400 acres of grapes or almonds shin-deep.
(Of course probability doesn't work like that; I was just trying to figure out how weird things might be getting.).Another flood will surely come, though, which means it's time to broaden our expectations.
New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.“Rising seas are slowly causing a trifecta of impacts along coastlines in Aotearoa: increasingly frequent flooding, coastal erosion and even permanent inundation,” says Dr Scott Stephens, NIWA Chief Scientist for Coasts & Estuaries.
Those higher sea levels coupled with another lunar cycle will drive a national leap in high-tide flooding, starting with what Thompson and researchers call “a year of inflection.”.
Flood flows on the Buller River this month were the largest of any river in Aotearoa New Zealand in almost 100 years, NIWA measurements show.Meanwhile, a NIWA monitoring station on the Buller River at Te Kuha, about 10km upstream, was continuously recording water levels throughout the flood.
A new study shows that nuisance flooding is exacerbated by dredging and the construction of piers and jetties that were intended to make coastal living easier but are in fact redirecting the flow of incoming ocean water and making high tides higher than ever before.
That was one of the findings in research, published this month in leading scientific journal Natural Hazards and Earth Science Systems, in which NIWA researchers describe how small increases in sea level rise are likely to drive huge increases in the frequency of coastal flooding in the next 20–30 years.
A new tool developed by The Nature Conservancy provides answers, using a research-based approach to help agencies, communities and other stakeholders obtain the information they need to prioritize floodplain protection and restoration.
In Boston, where many neighborhoods have been built and recently expanded in low-lying areas, an estimated $2.4 billion will be needed over the next several decades to protect the city from flooding, one study says.
Two reports released today by NIWA and the Deep South National Science Challenge reveal new information about how many New Zealanders, how many buildings and how much infrastructure could be affected by extreme river and coastal flooding from storms and sea-level rise.
The Mueller Report Is Here, Apple's Big Event, and More News. Getting a good night's sleep is the latest hot trend, and of course there are gadgets for that .
Fueled by rapidly melting snowpack and a forecast of more rainstorms in the next few weeks, federal officials warn that 200 million people in 25 states face a risk through May. Floodwaters coursing through Nebraska have already forced tens of thousands of people to flee and have caused $1.3 billion in damage.
With human-driven climate change not only heating up the world but exacerbating hurricanes and wildfires, fire ants are primed to reap their rewards. Fire ant colonies with multiple queens are denser—400 to 500 mounds an acre, instead of 40—and take more of a toll on the species around them.
“They should not be there; they know it’s not safe!” Citizens, journalists, and policymakers, express disbelief that people relocated to safer parts of the city return to their former, flood-prone neighborhoods.
“The Guidance provides methods that can be used for decision making under deeply uncertain conditions about the future, such as how fast sea level will rise, or how community coping capacity and vulnerability will change,” says Dr Stephens.
Falls in the average tracking speeds of hurricanes and typhoons, attributed to global warming, put more lives at risk Research published in Nature earlier this year showed that the average speed at which tropical storms track has slowed down by 10% since 1949.
Experts say you should never drive through fast-moving water.5 Dangers of Flooding in Hurricane Florence Experts provide the steps you can take to avoid them. Experts say you should never drive through fast-moving water.Drenching rains were inundating North Carolina on Friday as Hurricane Florence crawled inland at three miles an hour.
But Lochbaum points out that history proves such preparation might not be enough.In its 2012 post-Fukushima review, Florida Power & Light told the NRC that flood protections at its St. Lucie plant on South Hutchinson Island were adequate, despite failing to discover six electrical conduits with missing seals in one of the emergency core cooling systems.
What I have seen is that inland river flooding linked to hurricanes and heavy storms is a huge risk in the Southeast, but receives far less attention in emergency plans than coastal areas.
Wetland soil carbon, accumulated over millennia and now being released to the atmosphere at an accelerating pace, cannot be regained within the next few decades, which are a critical window for addressing climate change.
Yet all parties involved in housing know that cities are facing more rainfall and flooding due to climate change. However, the waterfront area still remains a flood plain, and is still affected by storm surges associated with climate change.
As we have explained elsewhere, short-term actions to adapt to coastal flooding can actually increase risks to lives and property. As we see it, market forces and public risk reduction policies interact in unexpected ways, reducing incentives for communities to make long-term plans for retreating from the shore.
"When I saw the first land images of inland water bodies, I was amazed at their quality," said Chris Ruf, CYGNSS's principal investigator at the University of Michigan in Ann Arbor. The CYGNSS satellites measure wind speed by determining how choppy the water is from a microwave signal bounced off the ocean surface.
The resulting analysis shows – for the first time – that the cost effectiveness of nature-based (green), artificial (gray) and policy solutions (like regulations) for reducing risk from storms and sea level rise can be directly compared – quantitatively – (apples to apples, so to speak) to one another across a region as large as the Gulf of Mexico.
