Four persons are travelling to different States of India. Who among the following is travelling likely in a high flood prone State?

The correct answer is The person travelling to Assam . Key Points Floods: Floods are relatively slow in occurrences and often occur in well-identified regions and within the expected time in a year. Floods occur commonly when water in the form of surface run-off exceeds the carrying capacity of the river channels and streams and flows into the neighbouring low-lying flood plains. Sometimes this even goes beyond the capacity of lakes and other inland water bodies in which they flow. Floods can also be caused due to a storm surge, high-intensity rainfall for a considerably longer period, melting of ice and snow , reduction in the infiltration rate, and presence of eroded materials in the water due to a higher rate of soil erosion. Unlike other natural disasters, human beings play important role in the genesis as well as the spread of floods. Indiscriminate deforestation , unscientific agricultural practices, disturbances along the natural drainage channels, and colonisation of flood plains and river beds are some of the human activities that play an important role in increasing the intensity, magnitude, and gravity of the floods. Various states of India face heavy loss of lives and property due to recurrent floods. Sometimes Tamil Nadu experiences flooding during November-January due to retreating monsoon. National Flood Commission has identified 40 million hectares of land as flood-prone in India . Assam, West Bengal, and Bihar are among the high flood-prone states. Hence, Option 4 is correct. Apart from these, most of the rivers in the northern states like Uttar Pradesh and Punjab are also vulnerable to frequent floods. States like Rajasthan, Gujarat, Haryana, and Punjab are also getting inundated in recent years due to flash floods. This is partly because of the pattern of monsoon and partly because of the blocking of most of the streams and rivers by human activities.
