Much research has been done on the description of drainage patterns in geography and hydrology.

What is parallel drainage pattern?

A parallel drainage system is a pattern of rivers caused by steep slopes with some relief. Because of the steep slopes, the streams are swift and straight, with very few tributaries, and all flow in the same direction. All forms of transitions can occur between parallel, dendritic, and trellis patterns.

Why drainage system is important?

This is the most important use of a good drainage system; it allows the free flow of water and in most cases prevents accumulation that can lead to flooding. Drainage systems also prevent the accumulation of stagnant water, which can encourage mosquitoes to breed.

When should surgical drains be removed?

Removal. Generally, drains should be removed once the drainage has stopped or becomes less than about 25 ml/day. Drains can be 'shortened' by withdrawing them gradually (typically by 2 cm per day) and so, in theory, allowing the site to heal gradually.
