  Statistical Study of Turbulence Near Piano Key Weir: A Review

  By Harinarayan Tiwari, Nayan Sharma

  Abstract: Piano Key Weirs are more efficient than the traditional Labyrinth weir and Piano Key Weirs can be an interesting solution for increasing the active storage of reservoir or for improving the safety of dam during extreme flood. This technology helps to reduce the reservoir sedimentation. It will also help in minimizing the sub-mergence effect. Flushing is vital for the preservation of long-term storage in reservoirs. However, downstream impacts such as …

  Introduction of New Flow Resistance Parameter for the Study Coefficients of Vertical Velocity Distribution

  By Harinarayan Tiwari, Nayan Sharma

  Abstract: Validity of log-law distribution of velocity in vertical section for alluvial channel under different localized bed and flow conditions is studied in this paper. In this study a new dimensionless parameter, Hari’s Number (Ph), whose value is to be taken as Q/νh, is proposed to relate the same with numerical coefficients of log-law distribution. It was found that the values of numerical coefficients could satisfactorily be correlated to the proposed …
