Outlet / Mogha
|
The hydraulic structure through which irrigation water is
discharged into watercourse.
|
Non modular outlet
|
An outlet in which discharge depends upon the hydraulic
head difference between FSL canal and FSL watercourse. E.g. scratchly outlet,
pipe outlet, in submerged condition
|
Semi modular outlet
|
An outlet in which the discharge depends upon water level
in canal only, and is independent of water level in watercourse. E.g. open
flume, adjustable orifice outlets.
|
Modular outlets
|
An outlet in which the discharge is independent of water
level in canal and watercourse.
|
Crest of mogha
|
The bed or sill of mogha at constricted section
|
LRTB
|
The elevation of lower side of roof block fixed in AOSM
outlet
|
Width of throat
|
Width of constriction section of outlet
|
Discharge
|
Volume of water flow per unit of time. Also known as flow
rate
|
Watercourse
|
Channel which conveys water from canal to the field for irrigation
purpose
|
FSL
|
FSL (Full Supply Level) represents water surface elevation
|
Slope
|
The difference in elevation per unit length (drop per unit
length)
|
Side slope
|
It is the slope of inclined surface of trapezoidal channel
and is expressed as ratio of horizontal to vertical. (Z:1)
|
Head loss
|
Decrease in FSL due to slope
|
Flow depth
|
Difference between water surface level and bed level of a
channel
|
Freeboard
|
The height of berm above the maximum designed water
surface
|
Turnout
|
Control structure that diverts water from watercourse to
the field
|
Check Structure
|
Structure that heads up the FSL up to elevation needed for
the turnout
|
Drop
|
Structure used to drop water at lower level and dissipate
its excess energy.
|
Syphon
|
Structure that carries the discharge of one channel
beneath the bed of another channel
|
Berm
|
Bank of the channel
|
Velocity
|
Distance covered in unit time
|
Wetted perimeter
(P)
|
Cross sectional length in contact with water
|
Hydraulic radius R
|
Ratio of flow area (A) to wetted perimeter (P) R=A/P It
expresses the shape of the channel.
|
Roughness
coefficient
|
The resistance or friction between water and channel. Also
known as Manning’s ‘n’
|
Hydraulics
|
Term denoting flow and characteristics of a liquid
|
Nomograph
|
Sloution to Manning’s equation in graphical form
|
Conveyance /
delivery efficiency
|
Ratio of the water delivered from the canal to water
delivered to the farm
|
Right of Way
|
The space fixed by the Government for a community
watercourse along its sanctioned route.
