Why deforestation and the removal of plants from the side of hills can lead to the flooding of lower areas of land?
Deforestation and the removal of plants from hillsides reduce the soil's ability to absorb water, as tree roots help retain moisture and stabilize the soil. Without vegetation, rainfall can lead to increased surface runoff, as there are fewer barriers to slow down or capture the water. This excess runoff can overwhelm lower areas, leading to flooding. Additionally, the loss of plants can result in soil erosion, further exacerbating the problem by increasing sedimentation in waterways.

What areas are in danger of flooding?
Low-laying areas close to water are at risk of flooding
Why do some areas in the Philippines get flooded easily during rainy days?
Some areas in the Philippines experience frequent flooding during rainy days due to a combination of factors, including poor drainage systems, urbanization, and deforestation. Many cities are built on low-lying land or near bodies of water, making them particularly vulnerable to heavy rainfall. Additionally, the rapid development often leads to the removal of natural vegetation, which reduces the land's ability to absorb water. These factors, combined with the country's susceptibility to typhoons, exacerbate flooding issues.
Why are humans more vulnerable to flooding?
Humans are more vulnerable to flooding due to factors such as population density in flood-prone areas, inadequate infrastructure for managing water flow, and lack of early warning systems. Additionally, human activities like deforestation and urbanization can exacerbate flooding by increasing surface runoff.
What are economical causes of flooding?
Economic causes of flooding can include urbanization leading to increased runoff, deforestation reducing natural flood mitigation, inadequate infrastructure like drainage systems, and poor land use planning leading to building in flood-prone areas. These factors can contribute to flooding events and amplify their economic impacts.
Frequency of flooding of ganga?
The frequency of flooding along the Ganga River varies significantly depending on the season and regional factors. Typically, flooding occurs during the monsoon season from June to September, when heavy rainfall and snowmelt increase water levels. Certain areas, particularly in Uttar Pradesh and Bihar, are more prone to flooding due to their low-lying topography and extensive riverbanks. Climate change and deforestation have also contributed to the increased unpredictability and severity of flooding events in recent years.
Are forest fires considered deforestation?
Forest fires can contribute to deforestation if they burn down large areas of trees and vegetation, leading to the removal of forest cover. However, not all forest fires result in deforestation, as some forests are able to regenerate after a fire. Deforestation, on the other hand, refers to the long-term and deliberate clearing of forests for agriculture, urban development, or logging, which permanently removes the forest ecosystem.
What are some hazards of the coastal areas?
Flooding.
Why do rural areas increase the chance of flooding?
Rural areas can increase the chance of flooding due to deforestation, which reduces the natural water absorption capacity of the land. Additionally, uncontrolled development and impermeable surfaces such as roads and buildings can cause water to run off quickly and overwhelm drainage systems. Lack of proper land management practices in rural areas can also contribute to soil erosion and sediment build-up in waterways, leading to increased flood risk.
What is the difference between flooding and flash flooding?
flooding means drowning of areas by heavy rain in considerable time, but flash flooding means, heavy rain in short time.
Is flooding on rivers caused by human activity rather than natural events?
Flooding on rivers can be influenced by both human activity and natural events. While natural factors such as heavy rainfall, snowmelt, and storm surges contribute to flooding, human activities like deforestation, urbanization, and poor land management can exacerbate these natural events. For example, the construction of dams and levees can alter natural water flow, leading to increased risk of flooding in certain areas. Therefore, human actions can significantly impact the frequency and severity of river flooding.
