    • Discharge Characteristics of Piano Key Weirs With and Without Upstream Siltation 

      Kumar, Binit; Kadia, Subhojit; Ahmad, Zulfequar (Peer reviewed; Journal article, 2021)
      The application of a piano key (PK) weir in a channel may lead to changes in the flow characteristics, upstream siltation conditions, and bed elevation. In this study, laboratory-based Type-A PK weir models with noses below ...

    • A Reformed Empirical Equation for the Discharge Coefficient of Free-Flowing Type-A Piano Key Weirs 

      Kadia, Subhojit; Pummer, Elena Marianne; Kumar, Binit; Rüther, Nils; Ahmad, Zulfequar (Peer reviewed; Journal article, 2023)
      The existing equations for the discharge coefficient of Piano key weirs (PKWs) use a limited range of experimental data, which means that they are inappropriate for wide parametric ranges that might lead to significant ...

    • Sediment Movement over Type A Piano Key Weirs 

      Kumar, Binit; Kadia, Subhojit; Ahmad, Zulfequar (Peer reviewed; Journal article, 2021)
      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 weir (PKW) models, which were recorded with a ...
