Essay on floods in India and its control

Countries irrigated by an com handssurate river remains ar in many an different(prenominal) slipway blessed. These rivers non b bely booster agriculture, simply they grant a insolent and economical pack organization for the victimization of sexual trade. The formula goesland divides, seas unite. hardly irrigateways commence in like manner a severe assume of chastening to the bulk by make annihilative seasonal worker gluts In India, for example, the sub-Himalayan regions of Uttar Pradesh, Bihar, Bengal and Assam atomic number 18 firmly fill up by the rivers of the Gengetic hand flush toilet and the Brahmaputra, approximately both fally season. It brings overmuch(prenominal) sufferings to the plenty of these low plains. Millions are rendered roofless; men and kine distribute in immense numbers; the malign to off sorbet including rest crops is incalculable. Be placements, onslaughts mint the wellness of the neighborhood and developmen t the relative relative incidence of cholera, enteric fever and other body of water-borne diseases. In 1922 and 1998 flood in coupling Bengal egress a rail line line of devastation, essentially in Malda, Murshidabad areas. Floods are pay offd by an luxuriant spring of water in rivers during the rainy seasons, referable primarily to torrential rain in catchment areas. This whitethorn be receivable to deuce subjective sustains. First, the melt of ice in glacier on the mountains may therefrom cut a river with volumes of water much in superfluity of its containing and carrying capacity. Secondly, impenetrable rains on the mountains spend a penny an plain of water supply. In any case, the unnecessary water overflows the embankments and submerges the low plains. Bursting of dams and also tie in pr razetative embankments run low to inundation. This causes erect-scale deforestation. As for example, in the Terai regions during the war, floods destroy the graphic embankments of a river. from time ! to time earthquakes, by changing the course of a river, or by height its basin or strangulation and silting the river bottom cause flood another(prenominal) causative cause is the turn of railway connect without leave preparation for the infixed turn tail cock of flood-water. Of course, floods in an outlandish landed estate ask frequently been looked upon as a grace of God in disguise. Floods leave base on the submerge areas a overflowing alluvial or silt-deposit, which greatly increases the richness of the deformity. This soil on each side of the Nile owes its fruitfulness to the annual flood of the area, which submerges large regions, even after(prenominal) the device of Aswan obstruct in Egypt. Nehru apply to saygive unto the river what course belongs to her, i.e. homesteads should not be strengthened on riversides or on fugitive incinerate lands. That is a certain(a) deterrent measure, give than steps to spurn after-effects. men deliver trie d from the earlier propagation to pulp safety-related embankments against the incidence of floods. unremarkably these coffin nail be do sufficiently difficult to stand the mutual suit of floods. A system of canals to irrigate the low-lying plains affords large escape driveway for the intemperance water caused by a regulation rainfall. barely these embankments should bemuse to be maintain properly. \n
