Floods are caused by an overflow of water onto land that is normally dry. They can occur in any area, but they are most common in low-lying areas and near rivers and streams.
There are a number of factors that can contribute to floods, including:
- Heavy rainfall: Heavy rainfall can cause rivers and streams to overflow, leading to flooding.
- Snowmelt: Snowmelt can also cause flooding, especially if it occurs rapidly.
- Deforestation: Deforestation can increase the risk of flooding by reducing the amount of vegetation that can absorb water.
- Poor drainage: Poor drainage can also contribute to flooding by causing water to pool in areas where it cannot flow away.
