Factors contributing to Bihar’s high flood risk include:

The correct answer is: d) All of the above

Bihar is a state in eastern India that is prone to floods. The main factors contributing to Bihar’s high flood risk are:

• Heavy monsoon rainfall: Bihar receives an average of 1,000 mm of rainfall per year, most of which falls during the monsoon season (June-September). This heavy rainfall can cause rivers to overflow their banks, leading to flooding.
• Terrain and topography: Bihar is located in a low-lying region, with many rivers and tributaries. This makes it particularly vulnerable to flooding.
• Deforestation in catchment areas: Deforestation can lead to soil erosion and increased runoff, which can worsen flooding.

In addition to these factors, climate change is also expected to increase the risk of flooding in Bihar. As the Earth’s temperature rises, the intensity and frequency of monsoon rains are expected to increase. This could lead to more severe flooding in Bihar in the future.

The government of Bihar has taken some steps to mitigate the risk of flooding, such as building embankments and flood control structures. However, more needs to be done to protect the state from the devastating effects of floods.
