Using examples, highlight how river basins ar managed to enable human activities to develop. River basins (or catchment aras) are the areas from which piddle drains into a river. They vary greatly in characteristics further if are all managed to offer human activities to develop. I allow analyse this management through analysing hard and soft chassis in both LEDCs and MEDCs. The River Thames in the MEDC of the UK flows through the major urban areas of London and Oxford. Human activities have reachly developed on nursing home the river for its transport, body of water and tourist resource. However, careful management is needed to cling to these economically valuable settlements from flooding. In London, flooding comes both from the marine (in tidal flooding) and from the river (in tide locking and river flooding) as well as on the land (from sewer flooding and surface water flooding). The Thames Barrier protects 420 000 London properties, Â£80 billion of property a nd 1.25 cardinal number people from storm surges from the North Sea: a behave example of hard engineering. Â£535 million has been spent on a 520 metre removable barrier that is the second largest in the world. However, it govern one day not be big generous as due to global warming and rising oceanic levels water may one day breach its defences.
there are plans for a new defence further into the Thames estuary or for a Â£4 billion overhaul of the existing Thames barrier. However, this unsustainable, pricey and side-effect causing defence (with water flowing to the sea held all right by the flood barriers risking flooding in London) is not very su! stainable. In the LEDC, Bangladesh, river basins are managed to extract maximum benefits and minimum consequences from the subjective phenomenon of annual floods. The Flood Action Plan, funded by the World Bank, is embarking on a 100 year plan to build 8000km of levees in a country with extreme social problems. This is because flooding kills many a(prenominal) people in the annual floods that occur in Bangladesh because...If you motive to get a full essay, order it on our website: OrderCustomPaper.com
