Piano key weirs (PK weirs) are generally installed on low head dams to enhance the discharging capacity. Such weirs are preferred over the other spillways if the length available for the construction of the spillway is limited and high discharge is to be passed at low head to avoid flood inundation in upstream. This newfangled weir having zig-zag shape changes the flow configurations which lead to scour downstream of the weir. A study on scour formation downstream of a PK weir is presented in this paper. Experimental investigations were conducted on three cycles PK weir to investigate scour pattern downstream of inlet and outlet keys with and without solid apron. Variation in observed maximum scour depth (ds) with tail water depth (yt) was ...
