"cullis"এর সংজ্ঞা এবং অর্থ

What is a "cullis"?

A cullis is a small groove or channel carved into a stone or masonry surface to direct water flow. This feature is designed to help manage rainwater or runoff, preventing it from pooling on surfaces and reducing the risk of water damage. Cullises are commonly found in the construction of walls, pavements, or drainage systems, ensuring that water flows away from critical areas and is directed toward drainage points. Their design is important for maintaining the integrity of structures while enhancing the effectiveness of water management systems.
