One Flood Can Cause Major Change

first_imgSingle large floods can change landscapes more than precipitation, a study in the Himalayas shows.European geologists went to Tibet to figure out the role of large floods in the complex landscape of the Himalaya Mountains. They conclusions are stated in a preface:Glacial lake outburst floods (GLOFs) are exactly what they sound like. The sudden emptying of a glacial lake in high-topography regions like the Himalaya can quickly destroy everything in its path. Cook et al. intercepted a GLOF in the Bhotekoshi and Sunkoshi river valleys in central Nepal as they were monitoring the region in the aftermath of the 2015 Gorkha earthquake. They found that a massive amount of erosion occurred during the outburst flood, which suggests that GLOFs may be the primary factor in landscape evolution for these regions.The paper by Cook et al, “Glacial lake outburst floods as drivers of fluvial erosion in the Himalaya,” was published in Science. The team says that these large floods, which can transport boulders a meter or more in diameter, are not that rare.The frequency of GLOFs in the central Himalaya is difficult to establish, because records are incomplete and recorded floods may not be correctly identified as GLOFs. Nevertheless, GLOFs are relatively common in the Himalaya, with a major flood occurring at least once every 2 years on average.The site this team studied was instructive, suggesting that a GLOF can hit a particular site once every 30 years. The Abstract says,Himalayan rivers are frequently hit by catastrophic floods that are caused by the failure of glacial lake and landslide dams; however, the dynamics and long-term impacts of such floods remain poorly understood. We present a comprehensive set of observations that capture the July 2016 glacial lake outburst flood (GLOF) in the Bhotekoshi/Sunkoshi River of Nepal. Seismic records of the flood provide new insights into GLOF mechanics and their ability to mobilize large boulders that otherwise prevent channel erosion. Because of this boulder mobilization, GLOF impacts far exceed those of the annual summer monsoon, and GLOFs may dominate fluvial erosion and channel-hillslope coupling many tens of kilometers downstream of glaciated areas. Long-term valley evolution in these regions may therefore be driven by GLOF frequency and magnitude, rather than by precipitation.The classic GLOF in the western hemisphere was the one that caused the huge Lake Missoula Flood. That GLOF carved the extensive Channeled Scablands in eastern Washington State, cutting through solid lava rock in a matter of hours or days. The authors do not mention that case, but the evidence for a flood as the cause of the scablands catapulted J Harlan Bretz from scorn to fame. His flood theory went from maverick to mainstream quickly, after decades of ridicule by his peers. Other notable dam-breach events in the western hemisphere include Mt St Helens, Earthquake Lake, and Gros Ventre. Search “dam breach” for more examples.Falling rocks can explode so hard that only nuclear weapons beat them (New Scientist). The power of falling rock is described as much greater than expected. “If falling rocks are big enough and hit the ground hard enough they can create a blast so intense that the rocks are pulverised into powder. Such extreme rockfalls are followed by a shockwave that can snap trees hundreds of metres away.”Explosive lies: how volcanoes can lie about their age, and what it means for us  (The Conversation). If volcanoes can lie about their ages, what else in geology is lying?Looking at those GLOF floods, if we took just half the assumed age of the Earth, rounded down to 2 billion years, that would translate to 67 million GLOFs! Does that make any sense? Maybe the Earth is much younger, would you think?The fact that this team states that “the dynamics and long-term impacts of such floods remain poorly understood” speaks poorly of open-mindedness in the geological community. When will they learn their lessons? Landscape changes don’t have to take millions of years. Forces of sufficient magnitude can accomplish a lot of change quickly.(Visited 660 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Soweto to Oxford and beyond

first_imgTamara O’ReillyIf the Rhodes Scholarship Trust were looking for a poster boy, Nhlanhla Dlamini would probably make the cut.As the latest recipient of the generous and prestigious Rhodes scholarship, 23-year-old Dlamini possesses all the certificates, medals, blazers and fancy “colours” that have come to be expected of applicants.The scholarship, founded by Cecil John Rhodes more than a century ago, will see him begin reading for his Masters in African Studies in September 2008 at University of Oxford, England. Dlamini views this as a vital step in achieving his goal of playing an active role in the broader development of his community, and ultimately Africa.“I understand that my analysis of Africa’s problems is incomprehensive. It is this acknowledgment that leads me to want to pursue a Masters in African Studies,” he says. “It will broaden my knowledge of African economics, history and sociology – three essential areas in understanding Africa’s context and challenges. By being in a class that will explore socio-economic concepts in Africa, I will be able to deepen my passion for my continent by grounding it in evidence and research.”His selection, over several other hopefuls from the Gauteng, North West, Limpopo, and Mpumalanga regions who no doubt displayed credentials that were also admirable, has not surprisingly been stunning.“I am extremely grateful at this stage to all those who have influenced me and contributed to moulding me into the person I am today,” says Dlamini. “Everyone has been overwhelmingly congratulatory and happy for me. It’s been a humbling reminder just how many friends and family members I have who are always rooting for me.”‘Resigned to a life of hardship’Although he was born in Soweto, at age seven his family moved to a traditionally white suburb and he was transferred to a multiracial school.Beyond the challenges of acculturation, both his parents were also retrenched from their jobs in the early 1990s, resulting in significant financial woes for his family.“I was convinced at the time that my family and I were resigned to a life of hardship,” says Dlamini.In 1992, what he calls a “seemingly small event” changed his outlook on what he could achieve academically.“At the end of Standard One [now Grade Three], I was invited to a prizegiving. I knew nothing of prize giving or what actually happens at such evenings. It turned out I was awarded the “Most Conscientious Student “ award. For the first time since I had moved to my new school, my background didn’t matter. It didn’t matter that I came to school in a jalopy or that I was part of an awkward minority in the school.”By the end of his secondary education at Marist Brothers College in 2001, Dlamini finished top of his class with five distinctions and full academic colours. He had also by then amassed several other awards in the areas of academics and community work. In Grade 11, he became the first pupil in the school’s history to be awarded an Honours Blazer, an accolade usually reserved for final year students.In 2002 he enrolled for a BCom Degree in Information Systems at the University of the Witwatersrand in Johannesburg. He graduated cum laude, making the Dean’s Merit List every year and pronounced Wits University Council’s Academic Merit Scholar from 2002 to 2004.Dlamini is an avid sportsman with several school and university captaincies to his name in the games of rugby and soccer. He is a national silver medalist in martial arts.He is currently employed in Atlanta, USA as a consultant for McKinsey & Company, a firm that advises leading companies on strategies around operations, staff and advancing their business.Dlamini returns to South Africa in March 2008 and he has left the six months remaining until he begins at Oxford without serious commitment for now, affording him well-deserved time to “tie up loose ends and perhaps take a road trip through the country”.Useful linksRhodes Scholarship WebsiteWits Universitylast_img read more

Ohio’s 2018 county yields now available

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Bruce Clevenger, CCA, Ohio State University ExtensionThe 2018 Ohio county estimates for crop yields were recently published by the USDA-National Agricultural Statistics Service. This annual report provides a look back to the previous production year and give an average of planted and harvested acres as well as the county yield in bushels per acre and a total estimated production for the county. The report additionally groups counties into nine reporting districts and provides an overall state yield estimate for corn and soybean. Ohio county estimates for the 2018 wheat crop were released back in December of 2018.Western Ohio continues to lead the state in both corn and soybean yields and production. The counties leading the corn yield estimates were Greene, Clinton and Auglaize Counties reporting 214, 213 and 210 bushels per acre, respectively. The State corn yield estimate for Ohio is 187 bushels per acre with a total production estimate at 6.17 million bushels. The counties leading the soybean yield estimates for 2018 were Mercer, Auglaize, and Van Wert Counties reporting 67.5, 66.3 and 65.7 bushels per acre, respectively. The State soybean yield estimate for Ohio is 58 bushels per acre with a total production estimate at 2.88 million bushels.The Ohio county estimates are valuable to farmers, crop insurance, economists, and USDA. Revisions to this data can be given at a later date by USDA. The complete data can be viewed online in the searchable Quick Stats or the County Estimates reports. Corn data is available from 75 Ohio counties whereas soybean data is available from 72 Ohio counties.

This January marked the 30th anniversary of the Macintosh computer. Monday marked the first day of Apple’s 25th Worldwide Developers Conference.See also: Apple Celebrates 30 Years Of The Mac ComputerCEO Tim Cook kicked off the conference with a couple more impressive statistics from Apple, and peppered them throughout his keynote. Here’s our latest look at Apple by the numbers, courtesy of Cook:There are now 9 million registered developers on the Apple platform. What’s more, there are 50% more registered developers in 2014 then there were in 2013.The youngest Apple developer attending WWDC is 13 years old. Apple sold 80 million Macbooks last year. That means, Cook observed, that while the computer industry as a whole declined by 5%, Macs grew by 12%.Since OS Mavericks launched in October 2013, user adoption has risen to 51%. Cook used this moment to add a subtle dig in Microsoft’s direction; Windows 8, launched in October 2012, only has 14% adoption now. Of course, it’s worth pointing out that while Mavericks is free, Windows 8 is far from cheap.Apple has sold more than 800 million iDevices in its lifetime. That includes 100 million iPod Touches, 200 million iPads, and more than 500 million iPhones. The company is still accumulating new users. 130 million customers who bought an Apple device in the last twelve months were buying their first ever Apple product.iOS 7 had an 89% adoption rate for iPhone users, compared to 9% for Android’s KitKat. iOS7 also had a 97% satisfaction rate, according to Cook.98% of Fortune 500 companies use iOS, senior vice president of Software Engineering Craig Federighi said on stage at WWDC.There are 1.2 million apps available on the App Store, 300 million App Store visitors every week, and 75 billion apps downloaded, Cook said.Just 49% of people used a passcode before Touch ID. Now, on the iPhone 5s, 83% of people use Touch ID or a passcode.   The lastest version of Xcode, Apple’s suite of software development tools, was downloaded 14 million times.Screenshot via WWDC lauren orsinilast_img read more

Theres More To Measuring An Olympic Course Than Just Measuring It

If, like me, you thought measuring a race course — marathon, race walk or otherwise — was as simple as driving a car around the circuit, you would be mocked by Katz and company. Turns out that a car’s odometer is fairly imprecise and that the preferred method of course measurement is much more artisanal. It requires only a calculator, 100-meter steel tape, a bicycle fitted with a GPS, and a device called a Jones Counter, which counts the rotations of the bike’s front axle — almost exactly 11,000 “counts” per kilometer.To calibrate the bike for the official course measurement, Katz used the steel tape to measure out 300 meters on the course, taking into account any possible expansion or contraction of the tape from the day’s temperature (there’s an adjustment coefficient for that). Then Katz rode the bike back and forth from Point A to Point B to see how many counts of the Jones Counter occurred over that 300 meter mark. Voilà! The bike was ready to track the rest of the course.“It’s very simple — I can teach you everything that I know about measuring if you have 15 minutes,” Katz told me. So then what makes him so good? “I’m a little bit more detail-oriented; I’m an official pain in the ass,” he said.It’s not quite as simple as Katz lets on, but it is a simpler method than I expected from the person ultimately responsible for ensuring that any records set in road races at the Olympics are in fact records. “He’s exactly the person whom we need for a high stakes measurement like the Olympics,” said Imre Mátraházi, the technical manager of the competitions department of the International Association of Athletics Federations, the international governing body for track and field.The trickiest part of course measurement, said Katz, is cutting the tangents. These can be corners or other parts of the course where athletes could find a shorter route. “If I was going to race you down the road for a million dollars and the road undulates, how are you going to run?” Katz asked. “You’re going to take the shortest path.”During the official measurement process, Katz biked the course, usually less than a foot away from the curb or barricades, to make sure that an athlete couldn’t physically run anything less than the course he’s measuring. He did it several times, biking every possible route that someone could take on the course to ensure that none is too short. But there’s an extra precaution built in as well, known as the short course prevention factor: All international races must be an extra 0.1 percent long — meaning today’s 50 kilometer course is actually 50.05 km, or an extra 50 meters long. Photograph by Allison McCann David Katz is the official course measurer for the race walk at the Rio Olympics. Allison McCann Katz has had help at this Olympics, as is customary, from a Brazilian husband and wife, members of the organizing committee for the Rio Games. They did the initial measurements before Katz came through with the final verdict. “My measurement came out a little better than their measurement,” Katz said matter-of-factly, but he praised their work too. “They are top-notch measurers.”With just over an hour left in the race walk, everything was going smoothly — no London race walk barricade disasters, at least. The current world record holder — France’s Yohann Diniz — was on pace to break that record (he would eventually fade well off pace). At the 25-km mark, he was almost 2 minutes ahead of Slovakia’s Matej Tóth, who eventually won. No world records were broken, so it’s unlikely that someone will re-measure Katz’s course after the Olympics are over. “I’m scared stiff about making a mistake; I double-check everything,” Katz said. But when I asked him whether he’s ever made one, he can’t remember a time he has. Photograph by Allison McCann We’re on the ground in Rio covering the 2016 Summer Olympics. Check out all our coverage here.RIO DE JANEIRO — It’s 7 a.m. The sun has barely risen, but for the better part of an hour, David Katz has been riding his bike around the course for the men’s 50-kilometer race walk later this morning. “More, more, more!” he shouts in the direction of a crew of guys arranging cones on the course, unhappy with the gaps around the second turn. Authority radiates from his neon orange vest, which reads: ROAD COURSE MEASURER.This is not Katz’s first Olympic course measurement rodeo. Or his second or third. He was the official marathon and race walk course measurer for the 2012 London Olympics (there’s only one official measurer, tasked with ensuring that the length of a road course is measured to spec, but usually several others help) and is back again in that role in Rio. He’s been involved with Olympic course measuring as far back as the 1984 Games in Los Angeles. And he’s been organizing and measuring road course races in New York in his spare time for more than 40 years.He’s a bit of a legend, as far as course measurement nerds go. “He is one of the best in the world,” said Wang Tak Fung of Hong Kong, a 20-year veteran of the course measurement game who came early to the race walk event to watch Katz in action. He seemed very impressed that Katz had lugged his steel measuring tape with him — a necessity only during official measurements (which were done weeks ago) and not for this morning’s slight tweaks and adjustments. The day of the race isn’t for official measuring; it’s for double-checking that the measurement is still accurate even after cones, barricades and water tables have been added to the course.“Not too many people do a measurement like that, but I will do it right before the start of the race,” said Katz, a retired science teacher who lives on Long Island in New York. His attention to detail can be heard in every one of his shouts toward race organizers. He wasn’t pleased with the placement of the cones around the second turn of the race walk — they were creating too sharp an angle — so he rolled out his tape measurer (just a regular one) and adjusted them, ensuring that “no athlete has to compete for one extra centimeter.” read more

Luis Enrique plays down club differences

We started with some doubts, but after that, we were brilliant and scored some incredible goals.“We were very effective. We want to get back to how good we were before. What I’ve liked most in these 10 days is the attitude of the players.Sergio Ramos, Real MadridZidane reveals Sergio Ramos injury concern for Real Madrid Andrew Smyth – September 14, 2019 Zinedine Zidane has put Sergio Ramos’ availability for Real Madrid’s trip to Sevilla next weekend in doubt after withdrawing him against Levante.“From what I’ve seen, regardless of the results, I’m delighted. When I hear my name sung, I feel proud, but it’s the players who deserve it. Still, I appreciate it.“There are many things to improve on. Everything can change in a day. I’m not one of those who exaggerate in victory or martyr in defeat.“I’m looking for balance. I didn’t know there were six Real Madrid players in the XI, neither do I care;“They play for the Spanish national team, that’s it. They don’t play for one team or another. Our base is from Real Madrid and it looks good to me.“No-one from Barcelona? I only see a shirt, the national team’s one. Qualification?
