application of free vortex theory to estimating discharge coefficient for sharp crested weirs
Biosystems Engineering, 2010Co-Authors: Sara Bagheri, Manouchehr HeidarpourAbstract:Sharp-crested weirs are commonly used where highly accurate discharge measurements are needed to determine the flow rates in Hydraulic Laboratories, industrial applications and irrigation systems. Vortex theory and the definitive results obtained by Bazin and Scimeni were used to assess flow over rectangular sharp-crested weir and determine discharge coefficient. Laboratory facilities consisting of sharp-crested weirs with various widths and heights were used. The proposed theoretical analysis agreed well with the experimental observations. Also, the experimental data indicate that the suggested equation presents reasonable results for a large range of relative weir depths.

flow over rectangular sharp crested weirs
Irrigation Science, 2010Co-Authors: Sara Bagheri, Manouchehr HeidarpourAbstract:Sharp-crested weirs are the simplest form of over-flow spillway that commonly used to determine the flow rate in Hydraulic Laboratories, industry and irrigation systems, where highly accurate discharge measurements are needed. In this study, the experimental upper and lower nappe profiles in rectangular sharp-crested weirs are fitted by quadratic and cubic equations, respectively. In addition, free-vortex theory is used to simulate flow over this kind of weirs and determine discharge coefficient. Physical models of sharp-crested weirs with various widths and heights were considered. The proposed method agrees well with the experimental observations. Also, the experimental data indicate that the suggested equation presents reasonable results for the range of 0 < h/P < 9.

A novel platform to evaluate the dampening of water and solute transport in an experimental channel under unsteady flow conditions
Hydrological Processes, 2020Co-Authors: Samer Majdalani, Roger Moussa, Jean‐philippe ChazarinAbstract:This paper presents a novel platform to study the dampening of water and solute transport in an experimental channel under unsteady flow conditions, where literature data are scarce. We address the question about what could be the smallest size of experimental platform that is useful for research, project studies, and teaching activities and that allows to do rational experiments characterized by small space occupation, short experimental duration, high measurement precision, high quality and reproducible experimental curves, low water and energy consumption, and the possibility to test a large variety of hydrograph scenarios. Whereas large scale Hydraulic Laboratories have focused their studies on sediment transport, our platform deals with solute transport. The objectives of our study are (a) building a platform that allows to do rational experiments, (b) enriching the lack of experimental data concerning water and solute transport under unsteady state conditions, and (c) studying the dampening of water and solute transport. We studied solute transport in a channel with lateral gain and lateral loss under different experimental configurations, and we show how the same lateral loss flow event can lead to different lateral loss mass repartitions under different configurations. In order to characterize water and solute dampening between the input and the output of the channel, we calculate dampening ratios based on peak coordinates of time flow curves and time mass curves and that express the decrease of peak amplitude and the increase of peak occurrence time between the input and output curves. Finally, we use a solute transport model coupling the diffusive wave equation for water transfer and the advection-diffusion equation for solute transport in order to simulate the experimental data. The simulations are quite good with a Nash-Sutcliffe efficiency NSE > 0.98 for water transfer and 0.84 < NSE < 0.97 for solute transport. This platform could serve hydrological modellers because it offers a variety of measured parameters (flow, water height, and solute concentration), at a fine time step under unsteady flow conditions.
