To control the allocation of water to the fields, capacity structures are used in which the available flow in the canal is measured.
The allocation of water to the fields should be controlled to optimize the use of the water resource, measure the effectiveness of irrigation, reduce water consumption and reduce labor costs. The data obtained when measuring the volume of water applied to the field is essential to carry out the programming of water balance irrigation.
Cenicaña recommends the use of the RBC titrator to measure the amount of water delivered to each field. The RBC gauge is a wide-crested landfill with a ramp, which can be portable or built in the canal. The RBC calibration for capacity depends on the dimensions of the structure.
