As the intensity of hydrologic events and concerns of pollutants in stormwater runoff increase, it is critical to recognize the importance of stormwater management. Raingardens have been shown to filter pollutants from runoff and mitigate erosion by slowing runoff volume and velocity. Because these systems show great variability in soil configuration, size, and usage patterns, it is valuable to quantify their specific performance in terms of volume and water quality of the systems’ inputs and outflow. The aim of this study has been to monitoring and evaluating the performance of two raingarden systems recently established at the Landscape Architecture building on the Mississippi State University Campus. This is accomplished by installing sampling and monitoring devices (e.g. rainfall and runoff tipping buckets, automatic water samplers) to assess quantity and quality of the inflow and outflow components of the system. Water samples from stormflow events are collected and analyzed at the CEE Environmental Engineering Lab in Mississippi State University to assess their content of sediments and nutrients. Infiltration tests are conducted to assure pieces of information that could bring insights in the analysis. Field and laboratory datasets are analyzed to determine specific correlations and the system’s performance. This study results can validate rain gardens’ hydrology features and thus, can provide valuable support for future engineering site design guidance.
