What is an impermeable surface?
Unruly surface is a surface that cannot be penetrated with water. A classic example of an impermeable surface is tiles that are used to make roads and parking lots around the world. Roofing and other building materials are also classically impermeable. Routine human use of soil can also create impermeable surfaces; For example, dirty roads can develop highly compacted soil, which is effectively impermeable, and poor management of agricultural land can also create compacted soil conditions. In a rural community, coverage can be less than 10%, while in some cities it can approach 90%. The growth of impermeable surfaces is the main problem of environmental interest for many reasons.
When it rains, water is absorbed by the soil. From the soil it slowly flows into the grounds of groundwater, recharges them and reappears in the surrounding rivers, lakes and streams. While the soil can be swollen and wet, the floods are relatively rare because the natural environment is designed to absorb water from even heavy storms.However, the undeveloped surface does not allow the liquid to reach the soil, which means that it remains on the surface of the Earth, which causes a range of problems.
One of the most common problems associated with impermeable surface is floods. If the water has nowhere to go, the water level can radically rise even after a small storm. The permeable surfaces also inhibit the recharge of groundwater, create large polluted outflows and reduce soil aeration. In addition, they collect heat, which is much warmer and prevents the growth of trees and plants, which contributes to the development of heat by removing the shadow while reducing air quality, as trees and plants usually act as a giant washing machine to pull impurities out of the air.
conditions associated with impermeable materials are often compared to the conditions found in the desert. Many environmental agencies advocated changes in the field of policy to deal withOto the problem. For example, permeable and semi -permeable pavement can be used to return the water on the ground or flood water can be collected in tanks and redispered in a controlled manner. Such measures would be beneficial for the environment, in addition to the fact that communities safer to reduce floods.
