“…If take the influence of throat width into consideration of dependence variable, Equation(4) will be; (5) The dimensionless form of the discharge, can be represented by QL and dimensionless head is represented by ha/L. The dimensionless discharge can be expressed as the power function with a dimensionless head, Q L = K (h a / L) n (6) Where the coefficient (K) and the exponent (n) can be found through a regression analysis.…”

“…The main influential factor of the geometrical characteristics, as concluded by all the related previous research is the width of the throat, while the length of CTF has a little effect. Therefore, the width/length ratio has been adopted and its impact is studied extensively by the relevant studies Weber [5]. The suggestion a new approach in which condition a single equation was introduced to account the discharge for both free and submerged flow condition by Torres and Merkley [6].…”

This paper aims to conduct a series of laboratory experiments in case of steady-state flow for the new size 7 ̋ throat width (not presented before) of the cutthroat flume. For this size, five different lengths were adopted 0.535, 0.46, 0.40, 0.325 and 0.27m these lengths were adopted based on the limitations of the available flume. The experimental program has been followed to investigate the hydraulic characteristic and introducing the calibrated formula for free flow application within the discharge ranged between 0.006 and 0.025 m3/s. The calibration result showed that, under suitable operation conditions, the suggested empirical formulas can accurately predict the values of discharge within an error ± 3%.
