Abstract

In this paper, the discharge coefficient of piano key weirs is compared with that of curved planform labyrinth weirs. Results show that the discharge coefficient of piano key weirs is by 17.1% higher compared to that of curved planform labyrinth weirs. The difference in discharge coefficient of these two weirs reduces with an increase in hydraulic load and attainment of submerged discharge, when both weirs exhibit similar results.

Keywords
