The assessment of scour depth downstream of weirs holds paramount importance in
ensuring the structural stability of these hydraulic structures. This study presents …

This investigation deals with the mechanics of movement of singular quartz gravel and
coarse sand riverbed particles upstream and over the inlet key of three Type A piano key …

Abstract Piano Key Weirs (PKWs) are often preferred over other spillways for the dam
rehabilitation due to high discharging capacity. The present study investigates scour …

A Piano key weir (PKW) is a modern type of spillway that is used to improve the discharge
capacity of dams. The ongoing work on this complex structure is very challenging nowadays …

In this research, the flow and scour patterns downstream of type-A rectangular piano key
weirs (PKWs) were studied experimentally and numerically. Variations of the bed …

In this paper, the scour downstream of a trapezoidal Piano key weir (PKW) is investigated
under free and submerged flow conditions. For this purpose, an experimental model was …

The present paper aims to evaluate the local scouring of non-cohesive sediment beds
consisted of uniform sediment particles downstream of a D–type piano key weir in steady …

This study investigates the effectiveness of flow splitters in reducing scour downstream of
trapezoidal Piano Key Weirs through a comprehensive experimental study. Three distinct …

Introduction: According to the research background, increasing the approaching speed has
been reported as the most important factor in reducing the discharge capacity and also, the …

A major issue with weirs over erodible beds is the scour downstream, which can seriously
challenge their stability. This paper presents experimental results on trapezoidal type-A …
