Overview of Piano Key weir prototypes and scientific model investigations

The interest in Piano Key weirs (PKW) was increasing over the past years, both in terms of application and hydraulic research. Several systematic model test series were per-formed and published so far, originating from different hydraulic laboratories around the world. Therein, the key geometric parameters dominating the hydraulic capacity of PKWs were identi-fied as developed crest length, transversal weir width, height of the walls and key widths. The present paper compares the available data-sets provided by several laboratories and as con-structed on prototypes, partially including a systematic model testing of the relevant parame-ters. The present overview is based on the geometrical dimensions of the investigated and de-signed PKWs, without giving any hydraulic examination.
