a. The main irrigation network
primary channel to bring water from the weir to the secondary channel and to plots irrigated tertiary. The limit is at the end of the primary channels for the latter building.
secondary channel to bring water from the primary channel to tertiary plots served by the secondary channel. This channel is the limit ends on the last tap building.
bearer channel carrying irrigation water from another water source (not the source that gave water to the main building of the project) to the primary irrigation network.
advance tertiary channels to carry water from the tap building tertiary to tertiary situated across other tertiary. These channels include the authority of the irrigation department and therefore its maintenance responsibility.
b. Tertiary irrigation channel network
tertiary channels to carry water from the tap building tertiary main network into the tertiary and then to channel quarter. This channel is the boundary tip box for the last quarter
Channel quarter, bringing water from the box for the quarter through tertiary tap building or trench paddy rice fields
c. Border line Channels
In order to secure the channel and building it is necessary to set the demarcation line and building irrigation channels away specified in legislation demarcation line.
Channel Wasters
Tertiary discharge channel network
Channel waster quarters located within the tertiary, collect water directly from the fields and throw water into the discharge channel tertiary.
Channel waster and tertiary located in between patches of tertiary included in the same unit of secondary irrigation and hold water, either from the exhaust quarter and from the paddy fields. The water discharged into the network of secondary waster.
a. The main exhaust duct network
Channel accommodate secondary waster waster water from the tertiary network and discard the water to discharge directly into the network of primary or natural waster and outside the irrigated areas.
Channels primary waster water flow over the secondary discharge channels outside the irrigated area. Primary waster is often a natural discharge duct that drains the excess water into rivers, creeks or into the sea
b. Building for and Sadap
For building and tapping on a door equipped with a technical irrigation and discharge gauges to meet the needs of irrigation water suitable amount and at any given time. However, in certain circumstances frequently encountered difficulties in operation and maintenance so that it appears the proposal proportional system, which is building for and tapping without a door and measuring equipment but with the conditions as follows, (1) elevation threshold in all directions should be the same, (2 ) threshold to be the same shape so that the same discharge coefficient, (3) the width of openings proportional to the area of irrigated rice fields.
But realize that proportional representation could not be applied in irrigation serves more than one kind of plant from the application of group systems. To that establishes criteria to apply to remain on the door and measuring the discharge to meet three requirements proportionally.
The building is located in the primary and secondary channel at a branch point and serves to divide the flow between two or more channels.
Building tertiary tapping water from the primary channel or secondary to tertiary channel receiver.
Building for and tapping may be combined into one series of buildings.
Box-box for at tertiary channels split the flow to two or more channels (tertiary, subtersier and / or quarter)
