Development of a Mathematical Model for Urban Runoff Quantity and Quality

摘要

The development and efficiency of a quantity and quality mathematical model for urban runoff with simple input to be used in conjunction with studies related to urban waste water management is outlined. The model called a Modified linearized Subhydrographs Urban Runoff Model (MLSURM), is capable of simulating runoff for either separate or combined sewer systems. The quantity model basically represents the simulation of runoff flow for a given rainfall event based on simple hydrographs of each subcatchment area and the storm duration. The model is useful, however, for analysis of existing sewer systems, design of new sewer systems, land use planning, and effective land management.
