Estimation of accumulation parameters for urban runoff quality modeling

摘要: Many recently developed watershed models utilize accumulation and washoff equations to simulate the quality of runofffrom urban impervious areas. These often have been calibrated by trial error with little understanding model sensitivity various parameters. Methodologies for estimating best fit values parameters commonly used in these presented previously. In this paper, parameter identification techniques from measured runoff data are along a analysis Results application suggest need quantifying magnitude identifying shape constituent curves. An exponential curve is shown be more general than linear curves most models. When determining rates, attention needs given effects residual amounts constituents remaining after previous period storm or street sweeping.
