Why there is flood when it rains in Pakistan

 There are several reasons why heavy rainfall can lead to flooding in Pakistan. One major

factor is the country's topography, which includes mountains and valleys that can channel water into low-lying areas. Additionally, Pakistan has a high rate of deforestation, which can contribute to soil erosion and a lack of vegetation to absorb water. Urbanization and poor urban planning can also exacerbate the effects of heavy rainfall by paving over natural drainage areas and creating concrete surfaces that don't absorb water. Climate change and global warming is also causing heavy and unusual rainfall patterns, which can worsen the situation.
