Floods can occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and  industry. A   Fire and flood are two of humanitys worst nightmares. People have,therefore,always sought to control them. Forest fires are snuffed out quickly. The flow of rivers is regulated by weirs and dams.

But foresters have learned that forests need fires to clear out the brash and even to get seeds to germinate. And a similar revelation is now dawning on hydrologists. Rivers and the ecosystems they support need floods. That is why a man made torrent has been surging down the Grand Canyon. By Thursday March 6th it was running at full throttle, which was expected to be sustained for 6.

Spring Snow from as far away as Wyoming would melt and swell the Colorado river to a flow that averaged around 1,5. Every eight years or so, that figure rose to almost 3,0. These floods infused the river with sediment, carved its beaches and built its sandbars. C   However, in the four decades since the building of the Glen Canyon dam, just upstream of the Grand Canyon, the only sediment that it has collected has come from tiny, undammed tributaries. Even that has not been much use as those tributaries are not powerful enough to distribute the sediment in an ecologically valuable way. D   This lack of flooding has harmed local wildlife. The humpback chub,for example, thrived in the rust redwaters of the Colorado. Recently, though, its population has crashed. At first sight, it looked as if the reason was that the chub were being eaten by trout introduced for sport fishing in the mid 2. But trout and chub co existed until the Glen Canyon dam was built, so something else is going on. Steve Gloss, of the United States Geological Survey USGS, reckons that the chubs decline is the result of their losing their most valuable natural defense, the Colorados rusty sediment. The chub were well adapted to the poor visibility created by the thick, red water which gave the river its name,anddependedonittohidefrompredators. Withoutthecloudywaterthechubbecamevulnerable. E   And the chub are not alone. In the years since the Glen Canyon dam was built, several species have vanishedaltogether. These include the Colorado pike minnow, the razorback sucker and the round tail chub. Meanwhile, aliens including fathead minnows, channel catfish and common carp, which would have been hard, put to survive in the savage waters of the undammed canyon, have move din. F   So flooding is the obvious answer. Unfortunately, it is easier said than done. Floods were sent down the Grand Canyon in 1. In 1. 99. 6 the flood was allowed to go on too long. To start with,all seemed well. The floodwaters built up sandbanks and infused the river with sediment. Eventually, however, the continued flow washed most of the sediment out of the canyon. This problem was avoided in 2. This time, the USGS is convinced that things will be better. The amount of sediment available is three times greater than it was in 2. So if a flood is going to do some good, this is the time to unleash one. G  Even so, it may turn out to be an empty gesture. Cyberlink Powerdvd 11 Full With Activation on this page. At less than 1,2. Those glorious inundations moved massive quantities of sediment through the Grand Canyon,wiping the slate dirty, and making a muddy mess of silt and muck that would make modern river rafters cringe. Questions 1 7. Do the following statements agree with the information given in Reading Passage In boxes 1 7 on your answer sheet, write. TUREif the statement agrees with the information. FALSEif the statement contradicts the information. NOT GIVENif there is no information on this. Damage caused by fire is worse than that caused by flood. The flood peaks at almost 1. Contribution of sediments delivered by tributaries has little impact. Decreasing number of chubs is always caused by introducing of trout since mid 2. It seemed that the artificial flood in 1. In fact, the yield of artificial flood water is smaller than an average natural flood at present. Mighty floods drove fast moving flows with clean and high quality water.

Floods are peoples nightmare. In the past, canyon was raged by flood every year. The snow from far Wyoming would melt in the season of 8 and caused a flood flow peak in Colorado river. In the four decades after people built the Glen Canyon dam, it only could gather 9 together from tiny, undammed tributaries. Humpback chub population on reduced, why Then, several species disappeared including Colorado pike minnow, 1. Meanwhile, some moved in such as fathead minnows, channel catfish and 1. The non stopped flow leaded to the washing away of the sediment out of the canyon, which poses great threat to the chubs because it has poor 1. In addition, the volume of 1. Section 2. Going Bananas. A   The worlds favourite fruit could disappear forever in 1. The banana is among the worlds oldest crops. Agricultural scientists believe that the first edible banana was discovered around ten thousand years ago. It has been at an evolutionary standstill ever since it was first propagated in the jungles of South East Asia at the end of the last ice age. Normally the wild banana, a giant jungle herb called Musa acuminata, contains a mass of hard seeds that make the fruit virtually inedible. But now and then, hunter gatherers must have discovered rare mutant plants that produced seedless, edible fruits. Geneticists now know that the vast majority of these soft fruited plants resulted from genetic accidents that gave their cells three copies of each chromosome instead of the usual two. This imbalance prevents seeds and pollen from developing normally, rendering the mutant plants sterile. And that is why some scientists believe the worlds most popular fruit could be doomed. It lacks the genetic diversity to fight off pests and diseases that are invading the banana plantations of Central America and the small holdings of Africa and Asia alike. B   In some ways, the banana today resembles the potato before blight brought famine to Ireland a century and a half ago. But it holds a lesson for other crops, too, says Emile Frison, top banana at the International Network for the Improvement of Banana and Plantain in Montpellier, France. The state of the banana, Frison warns, can teach a broader lesson the increasing standardisation of food crops round the world is threatening their ability to adapt and survive. C   The first Stone Age plant breeders cultivated these sterile freaks by replanting cuttings from their stems. And the descendants of those original cuttings are the bananas we still eat today. Each is a virtual clone, almost devoid of genetic diversity. And that uniformity makes it ripe for disease like no other crop on Earth.
