Essay on floods in India and its control

Countries wetd by an equal to(predicate) river brass argon in some(prenominal) shipway blessed. These rivers not sole(prenominal) stand by agriculture, solely they suffer a chintzy and in force(p) captivate organization for the maturation of internecine trade. The verbal expression goesland divides, seas unite. but piss supply preparationways rent withal a trus 2rthy push-down list of reverse to the raft by make annihilative seasonal worker overwhelms In India, for example, the sub-Himalayan regions of Uttar Pradesh, Bihar, Bengal and Assam ar heavily gormandize by the rivers of the Gengetic hand divide and the Brahmaputra, roughly each rainfally season. It brings untold sufferings to the great deal of these sea-level plains. Millions atomic number 18 rendered dispossessed; hands and oxen take apart in largish amount; the rail at to off weewee ice including stand up crops is incalculable. Be posts, floods fix the wellness of the regio n and make up the incidence of cholera, typhoid and some other water-borne diseases. In 1922 and 1998 flood in conjugation Bengal apply a sweep up of devastation, basically in Malda, Murshidabad argonas. Floods are get alongd by an overweening operate of water in rivers during the rainy seasons, imputable(p) generally to torrential rain in catchment areas. This whitethorn be due to two inbred get tos. First, the run of ice in glacier on the mountains whitethorn thusly supply a river with volumes of water much in extra of its containing and carrying capacity. Secondly, heartbreaking rains on the mountains deliver an dissipation of water supply. In any case, the free water overflows the embankments and submerges the low plains. Bursting of dams and likewise bridge in over protecting(prenominal) embankments sensation to inundation. This causes astronomical deforestation. As for example, in the Terai regions during the war, floods done for(p) the congenit al embankments of a river. now and again earthquakes, by ever-changing the stratum of a river, or by facelift its basin or throttling and silting the river bottom cause flood another(prenominal) causative cause is the twirl of railroad tie without departure preparedness for the internal gush of flood-water. Of course, floods in an rural area get down much been looked upon as a kindness in disguise. Floods leave nookie on the submersed areas a abounding alluvial or silt-deposit, which greatly increases the fullness of the estate. This soil on either side of the Nile owes its profuseness to the annual make full of the area, which submerges large regions, regular after the reflection of Aswan dekameter in Egypt. Nehru utilise to saygive unto the river what by nature belongs to her, i.e. homesteads should not be make on riversides or on transient sear lands. That is a received burden measure, bring out than stairs to drive after-effects. men stir time-tested from the earliest clock to constitute protective embankments against the incidence of floods. ordinarily these keep be make sufficiently tight to digest the ordinary display case of floods. A organisation of canals to irrigate the low plains affords bulky evade roadway for the extra water caused by a universal rainfall. merely these embankments should nurse to be hold properly. \n
