Floods in the Indo—Gangetic—Brahmaputra plains are an annual feature. In West Bengal the southern and central parts are flooded by the Mahananda, the Bhagirathi, the Ajoy, the Damodar etc. However, despite the various steps undertaken over the last five decades, the trend of increasing damage and devastation brought by floods has posed a challenge to the Government as well as to the people. These areas lie in the states of Punjab, Haryana, Himachal Pradesh, Delhi, Rajasthan, Uttar Pradesh, Bihar and West Bengal Fig. The damage was maximum in Rohtak, Bhiwani, Sonepat, Jind, Kaithal, Ambala, Hisar, Gurgaon and Faridabad.
In 1954, when the policy was first introduced, Bihar had approximately 160 km of embankments. This river used to disappear in the sands of Rajasthan after flowing through Punjab and Haryana. Bangalore, Vishakhapatnam and Chennai suffered loses. Wireless Communication system installed in almost 550 stations is the backbone of the communication system required for flood forecasting activities. The erosion is experienced in some places on the left bank of the Ganga and on the right banks of the Ghaghra and the Gandak.
The total flood-prone area in the country has been estimated to be 45. Housing for All scheme incorporates the disaster resilience component. Eastern India receives medium annual rainfall that varies in between 1, 000 mm to 2, 000 mm. Since, the land under the marshes or low depression may hardly require much compensation and rehabilitation measures, this method are relatively in expensive. The indirect impact of floods is seen in disruption of rail and road communication, and of essential services.
This shows that there has been a rapid increase in the flood-prone area of the country. Quite often these rivers overflow their banks, causing destruction in the area. Rainfall is poor in nine meteorological subdivisions out of 36 subdivision each meteorological sub division covers a geographic area of more than ten revenue districts in India. In West Bengal, rivers like Mahananda, Bhagirathi, Damodar, Ajay etc. The peninsular country of India is rich in its varied geographical features.
Dredging is sometimes advocated for clearing river mouth or narrow constrictions. The increase in the use of high-technology equipment and tools in manufacturing and service industries have also made them susceptible to disruption due to relatively moderate ground shaking. Ganga River Region: The river Ganga and its numerous tributaries, of which important ones are the Yamuna, the Sone, the Ghaghra, the Gandak, the Kosi and the Mahananda, constitute this river region. Sarkar emphasized there has to be a long term solution to the problem of floods. The Himalayan regions are particularly prone to earthquakes. Most of the spots identified are close to some of the district's largest water tanks or basins of the Noyyal River.
These areas are under Indian control. North Indian Rivers such as Damodar, Kosi, and Brahmaputra are known for their proneness to floods. The peninsular nature of India as well as the possession of innumerable rivers makes the country quite prone to floods. This is the primary reason behind Chennai floods. Though the regions of the country away from the Himalayas and other inter-plate boundaries were considered to be relatively safe from damaging earthquakes, the presence of a large number of non- engineering structures and buildings with poor foundations in these areas make these regions also susceptible to earthquakes. He said the impact of floods can be minimised by adopting an optimum combination of structural measures such as large storage reservoirs, detention basins and embankments and non-structural measures like flood forecasting, flood plain zoning and catchment area treatment. There has been passive resistance on the part of the states to follow up the various aspects of flood plain management including possible legislation.
The Chambal and the Betwa meet the Yamuna and add to the flooding capacity of the Yamuna. India is one of the worst flood-affected countries in the world and accounts for one fifth of global death count due to floods. Flood Management in India Why Flood Management in India? It is vulnerable to windstorms from both the Arabian Seaand Bay of Bengal. Conclusion Today, the country faces the twin challenges of floods and droughts that recur every year. Heavy rains lead to a rise in volume of the river load, which causes change in river course.
The flood of August- September 1960 is an eye opener. The Brahmaputra River Region : In the Brahmaputra basin, floods are almost an annual feature. Cyclones typically strike the East Coast of India, along the Bay of Bengal, ie. But the failure of dams in earthquakes and operation of releasing the water can cause floods in the lower areas. Areas of , Kachchh and Ladakh don't receive a lot of rainfall during the year.
