What is the function of drainage?
The purpose of drainage is to remove unwanted water from the human environment (17). It is often difficult to make a clear separation between 'unwanted' and 'wanted' water, as people will usually use surface water, for example for irrigation or watering animals.

What is drainage and types?
Surface drainage systems remove excess water from the land's surface through channels or ditches. In some cases, the ground surface is shaped or graded to create sloping toward the channels. Different types of surfaces drainage systems are open drains, humps and hollows, levees, and grassed waterways.

What is drainage and its advantages?
Drainage promotes beneficial soil bacteria activity and improves soil tilth. There is less surface runoff and soil erosion on drained land. Improved field machine trafficability reduces soil structural damage. Soil compaction is reduced and less energy is required for field machine operations.

What are two advantages of surface drainage?
Advantages of surface drainage are to minimize the duration of ponded water that inundates crops, and to minimize the prolonged saturation of soil which restricts gas (oxygen and carbon dioxide) exchange with the soil and plant root system or which prevents cultural operations.

What is the type of surface drainage?
Surface drainage systems typically consist of an outlet channel (existing natural stream or constructed channel emptying to a natural stream), lateral ditches, and field ditches.
