2.Sediment deposition

3.Deforestation

Select the correct answer using the code given below.

A. 1 and 2 only

B. 1 only

C. 2 only

D. 1, 2 and 3

Explanation:

The causes of flood in India are as follows:

i.Heavy rainfall: Heavy rain in the catchment area of a river causes water to over flow its banks, which results in the flooding of nearby areas.

ii.Sediment deposition: River beds become shallow due to sedimentation. The water carrying capacity of such river is reduced. As a result the heavy rain waters over flows the river banks.

iii.Deforestation: Vegetation hampers the flow of water and forces it to percolate in the ground. As a result of deforestation, the land becomes obstruction free and water flows with greater speed into the rivers and causes flood.

iv.Cyclone: Cyclone generated sea waves of abnormal height spreads the water in the adjoining coastal areas. In October 1994 Orissa cyclone generated severe floods and caused unprecedented loss of life and property.

v.Interference in drainage system: Drainage congestion caused by badly planned construction of bridges, roads, railway tracks, canals etc. hampers the flow of water and the result is flood.

vi.Change in the course of the river: Meanders and change in the course of the river cause floods. (vii)Tsunami: Large coastal areas are flooded by rising sea water, when a tsunami strikes the coast. Hence, all options are correct.
