    Numerical model for hydrodynamics simulations of Trabalhador channel

    TitleNumerical model for hydrodynamics simulations of Trabalhador channel

    Abstract

    Purpose – The purpose of this paper is to construct a numerical model for the numerical analysis of the
    hydraulic transient profile in Trabalhador channel for filling and emptying maneuvers and to determine
    the water level in time. Model results support operational managers in the decision-making process.
    Design/methodology/approach – Physical data were provided for the construction and calibration of the
    numerical model. The equations of Saint-Venant were approximated by a finite difference scheme and
    the numerical model was written in Fortran. The results of filling and emptying of the channel simulations
    were compared with the measured water levels.
    Findings – Measured water levels and those simulated by the numerical model have shown good correlation.
    The time recorded for the filling and emptying of the canal was also close between the measured and
    simulated data. The simulation design flow pointed to inundation in the channel banks. Simulation water
    levels were slightly higher than those measured.
    Research limitations/implications – In this model, the combination of canals and pressure conduits was
    not considered.
    Practical implications – The findings confirm the measured time for filling and emptying of the canal,
    as well as inundation of canal banks for the maximum design flow. These results help in the management
    process.
    Originality/value – This paper presents a numerical model for hydraulic transient analysis in channels with
    good agreement with the field data.
