a. Quaternary plots
Plots quarter plot named in accordance with the rotation, followed by a serial number clockwise. Rotation plots were coded A, B, C and so on clockwise. Box quarter coded K, followed by the serial number of clockwise, starting from the first quarter cribs downstream tertiary box with the highest sequence number: K1, K2 and so on.
Figure 13. Example of plots Rotation System Nomenclature and Quaternary
Irrigation canal quarters are named according to the serviced plots quarter but with small letters, for example a1, a2 and so on.
Waster channel quarter are named according to the swath quarter discarded water, using small letters preceded by dk, for example DKA, dka2 and so on. Waster tertiary channels, coded DT1, dt2 also clockwise.
b. Network Wasters
Each building is equipped with a network of irrigation drainage network construction which is an integral part of the irrigation network of air-plugs. In general, the primary form of natural river discharge, all of which will be named. If there is a new primary exhaust channel to be created, then the channel that should be given its own name. If the exhaust duct is divided into sections, then each segment will be named, ranging from the downstream end.
Secondary waster is generally in the form of rivers or creeks smaller. Some of them already have names that can still be used, if no rivers or creeks will be indicated by a letter together with a serial number. These names will be prefixed with the letter d (d = drainage). Waster wasters tertiary is the smallest category and will be divided into sections with uniform discharge, and each is numbered.
Tertiary each will have its own serial number. Figure 14 is an example of a system of nomenclature for the discharge channel.
