    Abstract

    This paper presents a systematic approach for the economical design of rain-water quality control systems. For the design of runoff quality control system (RQCS), the rainfall-runoff process requires the local rainfall data recorded continuously. In this study the rainfall probability distribution is assumed to follow an exponential decay function. Applying the exponential decay function, the normalized curves are derived to explain the non-exceedance probability distributions. The optimal curves for the determination of the RQCS size are derived based on the overflow risk. Comparison of the optimal capture volume and peak runoff rate to those computed by an urban rainfall-runoff model (ILLUDAS) demonstrates that the optimal curves derived in this study can be utilized for the design of rain-water quality control systems in Korea avoiding an excessive computational effort by the rainfall runoff model.
