Various techniques are being developed and applied for the management of non-point pollutants. Especially, there has been an increasing interest in the techniques which work for both the restoration of hydrologic cycle and management of non-point pollutants. When the need for the management of non-point pollutants first arose, structural concept of BMP was developed. Recent years saw the expansion of management plans including precautionary land use techniques such as low impact development (LID). LID is usually applied to new development areas but lately is in extensive use with existing city areas. To analyze the effect of LID application on an industrial complex by using Strom Water Management Model (SWMM), a point with clear division of the soil pipe and rainwater pipe sections was selected for monitoring non-point pollutant runoff and analyzing the characteristics of the runoff in this study. Furthermore, to construct a SWMM-LID model of a small-scale catchment, RUNOFF blocks were subdivided into sections and six event data with satisfactory flow pattern were selected from 24 monitoring data collected over three years (2009-2011) to be calibrated, two more event data were used for verification to complete the construction of the model. LID key technologies were applied as four CASEs: existing condition of the city (CASE 1), application of rain barrel (CASE 2), rain barrel and tree filter box (CASE 3), rain barrel, tree filter box, and porous pavement (CASE 4) for short-term and long-term (seasonal) simulation analyses.
