Kinds of Open Channel :

" Canal – Flume – Chute – Culvert – Drop – open flow tunnel "

: Open flow tunnel-1

It is a channel designed as a relatively long time, and we use it in case of an obstacle

prevents the transfer of water from one place to another on the ground such as

mountains and hills or any terrain.

Drop:-2

The very similar the chute in format and is the closest to him than the rest of other species,

but the difference between him and that attributed the change in the short distances, unlike

the chute .

Culvert:-3

Channel are covered, flow through the channel is often almost 75-95% of the area of channel

uses this type of channels in the same drainage through dams or highways or railways and

parts that are difficult to drain through.

Chute: -4

is a channel having steep slopes which carries the water passing over the crest of spillway to

the river downstream .

Flume : -5

Is a channel often be based on the Earth's surface, and this type of channels used in

agriculture and irrigation fields of large sources of water for distribution is smaller.

Canal : -6

These types of channels are of great slopes and be relatively the slopes on the sides of the

land on which channel and are often used to transport water through the distal distances and

also for the distribution of water from the main source for the purpose of agricultural

irrigation.
