FAQs on Surface and Subsurface Drainage System Video Lecture - Civil Engineering Optional Notes for UPSC

1. What is a surface drainage system?
Ans. A surface drainage system is a network of channels and structures designed to remove excess water from the surface of the land, preventing waterlogging and flooding.
2. How does a subsurface drainage system work?
Ans. A subsurface drainage system consists of underground pipes or tiles that collect excess water from the soil and carry it away to a lower-lying area or a drainage outlet, effectively lowering the water table.
3. What are the benefits of a surface drainage system?
Ans. A surface drainage system helps to prevent erosion, improve crop yields, enhance soil structure, and reduce the risk of waterlogging and flooding in agricultural fields.
4. Is it possible to combine surface and subsurface drainage systems?
Ans. Yes, it is common to combine surface and subsurface drainage systems to effectively manage excess water in agricultural areas. Surface channels can work in conjunction with subsurface pipes to provide comprehensive drainage solutions.
5. How can one maintain a surface and subsurface drainage system?
Ans. Regular maintenance of a surface and subsurface drainage system includes clearing debris from channels, inspecting pipes for clogs, repairing any damage, and ensuring proper functioning of outlets to prevent water accumulation.
