Monitoring guideline based on low impact development

Abstract

Urban planning changes the regime, resulting in a new annual and seasonal hydrologic balance, causing frequency distribution changes of peak flows, magnitude and duration of high and low flows. These changes increase the surface runoff volume, decrease evapotranspiration volume, and groundwater recharge rate. Low Impact Development (LID) is used to create, retain, and restore natural hydrologic and water-quality conditions caused by human activities. Monitoring by element is necessary to confirm for LID. A streamlined monitoring guideline is presented that aids the development of strategies to assess the performance and effectiveness of sustainable storm water management. The guideline focuses on hydrology and water quality monitoring, site-specific, and watershed scales. This study puts emphasis on hydrology and water quality monitoring of an LID test site in South Korea. © 2014 WIT Press.
