Question

Explain relief and ecnomic importance of drainage system​

Answer 1

Answer:

Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies.

Answer 2

Explanation:

Building drainage is of great economic importance! 90% of all structural damage to basement areas can be prevented by proper drainage. Hence, it significantly helps to preserve the value of a building. Building drainage turns basements into living space for sports, leisure and recreation, because it keeps walls dry.
