چکیده
The modeling of broad crested weirs is expected to facilitate understanding, especially the behavior flow flowing through measuring instrument. under consideration hydraulic behavior, measurement accuracy, and discharge curve. In addition, there a relationship between water level upstream downstream spillway, as well variation loss energy height. From results this study, it was found that upstream, downstream, above threshold, for wide-threshold spillway. assumes Froude number occurs in model same field. So scale discharge, time, velocity volume will be able represent actual conditions length, width, height prototype 1: 100. methodology used carry out testing hydraulics laboratory by varying Q1, Q2, Q3, Q4, …. Qn, obtain variations weirs. relatively small with trend Y = 101.66x2 - 0.7359x + 0.0017 slope 1:2, 467.84x2 1.7816x 0.0022 1:1.5, -1140,4x2 0.6383x 0.0077 1:1 where meters X m3/sec.
