FIELD: construction.
SUBSTANCE: method consists in arranging near the acting irrigation channel the isolated measuring compartment made with the supply and discharge of water from the channel. The measuring compartment is formed with vertical walls 6 of a waterproof material - geomembrane 4 with protective gaskets of geotextile 5. The vertical walls 6 are reinforced by wooden boards 7, with the reverse ground 8 dumping. The water level in the isolated compartment is regulated by flat shutters. The anti-filtration element of geomembrane 4 and two protective gaskets of geotextile 5 is made in the form of a tooth to the depth of 0.5 m. The specific filtration flow is determined by the calculated dependence.
EFFECT: measurements of water losses for filtration are carried out without prior stopping and emptying the channel, by means of arranging an isolated measuring compartment.
