Quantity-Quality Simulation (QQS): A Detailed Continuous Planning Model for Urban Runoff Control. Volume I. Model Description, Testing, and Applications

摘要

A comprehensive mathematical model, the Quantity-Quality Simulation (QQS) model, for calculation of urban stormwater and combined sewer overflow pollution and the means for its control is presented. The model operates in a continuous mode with a five minute time step and accounts for the unsteady runoff and overflow behavior of total drainage systems. Lumping techniques, that calculate the runoff from drainage areas, are combined with detailed flow routing through main and interceptor sewer as well as other structures such as branches, overflows, basins, pump stations, control gates, and treatment facilities. The computer program calculates the runoff in the storm or combined sewer and in the receiving waters. The program package, written in Standard Fortran IV, comprises approximately 30,000 statements. Applicability of the QQS model is demonstrated in a number of comparisons with measurements of runoff quantity and several water quality parameters made in several catchments.
