PROCESS DETERMINING FLOW RATE OF WATER IN OPEN CANAL WITH PRISMATIC BED Russian patent published in 1998 - IPC

FIELD: measurement technology, land reclamation, irrigation systems. SUBSTANCE: process provides for arrangement of range line "k-n" at distance of L_k-kH_gate. from gate of partitioning structure, where H_gate. is total height of gate, of second range line "f-f" at distance L_f-fH_str, from drop structure, where H_str. is construction height of measurement section. Measurement is conducted over section formed between gate and drop structure of backwater with superprismatic condition of flow and flow rate of water is found by formula given in description of invention. EFFECT: improved reliability of process. 1 cl, 4 dwg
