Abstract: The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. For a given flow, roughness coefficient, and longitudinal slope, this method optimizes the channel section by minimizing ...

Abstract: A liquid analog model (LAM) is presented as a new hydrological laboratory device for rainfall–runoff modeling. The model is applied to simulate Nash’s model in the laboratory for real rainfall–runoff data. Due to its simple ...
