Tartalmi leírás:
Accurate estimation of discharge capacity and local hydro-dynamics are essential when designing hydraulic structures. Instead of the application of conventionally used empirical relationships, this study introduces a 3D numerical modeling technique which is capable to adequately predict both the discharge-upstream water level relationship and the flow field around weirs. The numerical model, REEF3D, is validated for different hydrodynamic conditions (free-flow and submerged flow) against laboratory data performed for an ogee type weir. Simulated water surface elevations compared with experimen-tal data together with the modeled flow field around the weir suggest that even the complex modular, transition and non-modular submerged cases can be reproduced by the numerical tool. The study proves that the herein applied numerical solver can be a good alternative of laboratory models for flow analy-sis at complex hydrodynamic conditions, especially where spatially strongly varying free surface characterizes the flow.
