A drainage structure is a man-made or natural feature designed to manage and control the flow of water, preventing flooding and erosion. These structures are essential components of drainage systems, which are integral to urban and rural infrastructure. Drainage structures can be categorized into several types based on their function and design.

One of the most common types is the drainage pipe, which is used to convey water from one point to another. These pipes can be made of various materials, including concrete, plastic, and metal, and are often laid underground or in open channels. Another type is the drainage culvert, which is a structure that allows water to pass underneath roads, railways, or other obstacles. Culverts can be circular, elliptical, or rectangular in shape and are designed to handle specific flow rates and water depths.

Drainage inlets are structures that collect water from surfaces such as roads, rooftops, and parking lots. These inlets are typically designed with a grate to prevent debris from entering the drainage system. Manholes are another type of drainage structure, providing access to the drainage system for maintenance and inspection. They are usually located at regular intervals along the drainage network and are equipped with lids that can be opened for access.

Drainage structures also include weirs and flumes, which are used to measure and control the flow of water. Weirs are barriers across a watercourse that raise the water level upstream, while flumes are open channels designed to convey water with minimal energy loss. These structures are crucial for flood control, water supply, and irrigation.

The design and placement of drainage structures are critical to the effective functioning of a drainage system. Factors such as soil type, topography, and climate must be considered to ensure that the structures can handle the expected water volumes and velocities. Regular maintenance and inspection are also essential to prevent blockages and ensure the longevity of the drainage structures.
