India faces heavy monsoon rains, overflowing rivers, cloudbursts, and urban drainage problems every year. In 2025, many cities are again at high risk of flooding. Some places are naturally flood-prone because of their geography, while in others rapid urban growth, poor planning, or climate change make the risks worse. Knowing which cities are most affected helps us understand where prevention, better infrastructure, and quick action matter most.

Reasons for Flooding

Several natural and man-made factors combine to make Indian cities prone to flooding:

• Heavy Monsoon Rains – Seasonal rains overwhelm drainage systems.

• River Overflows – Major rivers like the Ganga, Brahmaputra, Yamuna, and Jhelum flood during peak monsoon.

• Cloudbursts – Sudden, extreme rainfall in hilly regions causes flash floods.

• Poor Urban Drainage – Cities with clogged or old drainage systems cannot handle sudden water inflow.

• Urbanisation – Encroachment of floodplains, wetlands, and lakes reduces natural water absorption.

Top Flood-Prone Cities in India by 2025

The following cities face frequent floods due to their geographical location, river systems, and urban issues:

Main Challenges that Worsen Floods

• Unplanned Construction – Cities expand over rivers, lakes, and floodplains.

• Blocked Drains – Garbage and encroachments choke natural water channels.

• Climate Change – More intense and unpredictable rain patterns.

• Inadequate Preparedness – Weak early warning systems and poor disaster planning.
