An experimental investigation on flow characteristics of stepped spillway under varying slope & discharge conditions


Author(s): Er SV Baria, Dr. ML Gaur and NM Damor

Abstract:
The stepped spillway is the most effective hydraulic structure for dissipating energy downstream of the spillway crest. This work evaluates the hydrologic and hydraulic functioning of a prototype hydraulic structure as used in natural channels of small agricultural watersheds, by generating some of the basic information & other relevant parameters for the area under study. The overall values of key flow parameters (h, v, E, n, Fr, Re) have been suitably worked out and analyzed, which altogether gave a broad range under hydraulic structures with varied configurations in regards to discharges and the channel bed slopes. Physical model study plays a vital role in the planning and designing of hydraulic structures. A vast review was done on updated progress on the hydraulic structure and their relevant monitoring and evaluations in hydraulic flume as well as real channel flow conditions the discharges inside the hydraulic flumes were varying in between 0.5 to 5 L/s in the majority of experimental runs. Similarly, the channel bed slopes were kept varying in between 0.5 to 2 percent longitudinal slopes. Efforts are made to derive the real limits of flow conditions all along the channel with in-depth evaluations of flow parameters, flow regimes, and all associated flow conditions. Also, the values of Cd for specific stepped spillway hydraulic structures are attempted here with an effort to further extend its applicability to similar ungauged situations. The Cd values for the stepped Spillway were found the be in the range of 0.004 to 0.107 and alternate predictive equations in this regard too also synthesized in this study.
