ABSTRACTNonlinear weirs offer a relatively high discharge capacity under low water loads. Their efficiency, however, is decreased at high water loads due to the submergence of the weir outlet key. In the present study, sloping parapet walls with the

The piano key weir (PKW) is a developed type of labyrinth spillway with the ability to transfer large amounts of discharge by keeping executive costs constant. In this study, the parameters affecting the discharge coefficient of nine models were e

Piano key weirs are a new type of Weirs that are designed to improve dams discharge capacity. Generally in increasing the upstream head water decreases the discharge capacity this tyre of weir. Thus, in this research, the effect of discontinuous para

Piano key weirs (PKWs) with crown parapet walls effectively manage water levels and maximize storage. However, their efficiency is compromised by interactions between water flow and submerged outlets during rising water levels. This study investigate

Since the one of the application of piano keys weir is use in irrigation and drainage network, and it is possible that with decrease of discharge, the water level during dehydration is faced with a drastic reduction. Therefore, by creating Parapet wa
