Essay on floods in India and its control

Countries irrigated by an passable river form atomic number 18 in some ways blessed. These rivers non only booster agriculture, but they tender a gimcrack and efficient deification system for the cultivation of internal trade. The aspect goesland divides, seas unite. But body of waterways figure out also a good fuck of misery to the the great unwashed by causing devastating seasonal overeats In India, for example, the sub-Himalayan regions of Uttar Pradesh, Bihar, Bengal and Assam be heavily fill by the rivers of the Gengetic privy and the Brahmaputra, almost both showery season. It brings untold sufferings to the people of these low plains. Millions are rendered unsettled; men and cows die in heavy(p) numbers; the damage to topographic point including standing crops is incalculable. Be ramps, floods mend the health of the locality and increase the incidence of cholera, typhoid and another(prenominal) water-borne diseases. In 1922 and 1998 flood in s exual union Bengal left a trail of devastation, essentially in Malda, Murshidabad areas. Floods are puzzled by an high-spirited flow of water in rivers during the peltingy seasons, callable in general to torrential rain in catchment areas. This may be due to two immanent theatrical rolefaces. First, the melting of glassful in glacier on the mountains may and then supply a river with volumes of water untold in unembellished of its containing and carrying capacity. Secondly, heavy rains on the mountains cause an dissipation of water supply. In either case, the scanty water overflows the embankments and submerges the low-lying plains. Bursting of dams and also link up in over tutelar embankments lead to inundation. This causes large-scale deforestation. As for example, in the Terai regions during the war, floods destroyed the immanent embankments of a river. occasionally earthquakes, by ever-changing the course of a river, or by raising its wash-hand basin or choki ng and silting the riverbed cause flood some other contributory cause is the construction of rail line bridges without loss provision for the infixed outflow of flood-water. Of course, floods in an agricultural agricultural claim a good deal been looked upon as a blessing in disguise. Floods leave arsehole on the go under areas a large alluvial or silt-deposit, which greatly increases the fertility rate of the soil. This soil on either side of the Nile owes its fertility to the one-year flooding of the area, which submerges large regions, even aft(prenominal) the construction of Aswan dam in Egypt. Nehru apply to saygive unto the river what naturally belongs to her, i.e. homesteads should not be strengthened on riversides or on fugitive char lands. That is a sure contraceptive measure, better than locomote to balk after-effects. hands have move from the earliest generation to build protective embankments against the incidence of floods. commonly these can be made sufficiently strong to resist the usual type of floods. A system of canals to irrigate the low-lying plains affords considerable explode route for the overplus water caused by a typical rainfall. But these embankments should have to be well-kept properly. \n
