Investigating the Water Budget and Subsurface Hydrology of Two Rain Gardens in Calgary, Alberta
… stormwater from infiltrating into the soil. Rain gardens are a form of low impact development technology that mitigate some of these effects by promoting natural stormwater infiltration. Rain gardens have extensively been researched in warm and humid climates; however, less is known about …

A distributed modeling approach for evaluating hydrological effects of rain gardens in urban watersheds
… effects in urban watersheds under a continuous rainfall period. It is expected that rain gardens will have a significant effect in the reduction of peak discharge and volume for a range of different storms magnitudes including less frequent events. Rain gardens are small depressions covered by …

Distributed surface-subsurface modelling approach for evaluating the impact of rain gardens on steep terrain
… urban runoff quantity and quality from steep terrain areas. Stormwater BMPs provide sustainable, cost effective, and ecologically-friendly approach to maintain natural pre-development hydrological functions and prevent the delivery of contaminants to the receiving waters. Structural BMPs, in …

Modeling and analysis of phosphorus reduction by rain gardens and other BMPs in stormwater runoff from small urban developments
… the improvement in phosphorus concentrations if rain gardens are implemented on a fraction of residential areas in the Nashoba Brook watershed. The effectiveness of a rain garden at improving the phosphorus concentrations in runoff was evaluated by modeling the device in P8. Both the TDM site …

The Economic Water Model - a method and software program for assessing the impacts of storm water "green solutions" in urban areas
… needed for storm water "green solutions" such as rain gardens, bioswales, and rain barrels. Estimating average annual runoff at the property level is essential to providing precise estimates on the effectiveness of stormwater “green solutionsâ€� like rain barrels and rain gardens. This …

Community-based social marketing at the neighborhood scale : sustainable behavior or neighborhood sustainability?
… scale: first, to encourage the uptake of rain barrels and rain gardens; and second, to advance long-term sustainability as defined in the sustainable communities literature. My research focuses on the potential opportunities and limitations of CBSM in three very different neighborhoods in …

Watershed-level Analysis of Urban Raingarden Performance
… City of Kansas City began the project of "10,000 Raingarndens in Metropolitan Area" in 2008. For the project, there are a test area and a control area. Both have similar drainage areas and similar precipitation. In the test area, there are 135 rain gardens completed in June 2012. There are four …

Binghamton's missing teeth: a study of city-owned vacant lots in Binghamton, New York
… for surrounding residents. Urban agriculture, rain gardens and pocket parks are examples of how vacant lots can be reused to benefit communities.</p> <p>The purpose of this research is to build an understanding of (1) why city-owned vacant lots exist in Binghamton, New York; (2) how they are …

A framework for designing and optimizing green infrastructure network under uncertainty
… optimality at the subwatershed level. Moreover, rain gardens provide far more efficient stormwater treatment at the household scale in comparison to watershed scale, for which large-scale dry or wet basins are more efficient. The results show that for BCR, smaller subwatersheds are more cost …

Development of a Method to Compare Storm Water Best Management Practices at The University of Toledo
… into storm water collection systems, which drain directly into natural waters. These contaminants degrade water quality, harming human health and aquatic life. In order to address these concerns, storm water best management practices (BMPs) have been developed to reduce flow rates and improve …

NATURE-BASED SOLUTIONS FOR FLOOD RISK MITIGATION: MAPPING AND HYDROLOGICAL MODELING IN AN UNDER-RESOURCED URBAN AREA ON THE MISSISSIPPI GULF COAST
… permeable pavement, infiltration trenches, and rain gardens, selected by the stakeholders, in increasing infiltration and reducing runoff during both small and large design storms. I collected local-scale precipitation and water level data and applied it to calibrate a Stormwater Management …

Characterization of co-benefits of green stormwater infrastructure across ecohydrologic regions in the United States
… stormwater infrastructure (GSI) systems such as rain gardens, permeable pavement and bioswales are commonly used in municipalities to reduce urban flooding and water pollution. In conjunction with these direct benefits, GSI systems provide additional social and ecological "co-benefits". Our goal …

Analysis of Sinkhole Susceptibility and Karst Distribution in the Northern Shenandoah Valley, Virginia: Implications for Low Impact Development (LID) Site Suitability Models
… source through practices such as bioretention, rain gardens, and grass swales. The karst terrain that underlies the Shenandoah Valley presents a major barrier to the use of LID. Infiltration of surface runoff in karst landscapes may threaten groundwater quality and the stability of the bedrock. …

A comprehensive modeling approach for urban rainfall - runoff simulation
… worldwide, including surface flow, underground drainage flow and especially the inevitable flow connecting with underground infrastructures in highly urbanized areas. A comprehensive modeling approach and effective mitigation measures are necessary for urban risk assessment and management. Herein …

Guiding green stormwater infrastructure planning through socio-ecological vulnerability: An integrated and spatially scalable prioritization framework
"Green stormwater infrastructure (GSI; e.g., rain gardens, bioswales, green roofs) is widely used as a climate change mitigation strategy for its potential to reduce stormwater management problems (e.g., poor water quality, increased streamflow velocities, and flood risk due to impervious …

Towards Sociobiogeochemistry: Critical Perspectives on Anthropogenic Alterations to Soil Nitrogen Chemistry via U.S. Urban and Suburban Development
… certified yards or hydrologic focused yards (rain gardens in wet cities and xeriscaping in dry cities). This research found that regardless of yard type, all residential soils had elevated soil nitrate levels (an important water quality concern), and do not become more similar to native soils. …

Assessment of integrated green infrastructure-based stormwater controls in small to large scale developed urban watersheds
… biofilters, cascade biofilters, porous pavement, rain gardens monitored at small scales (individual GI performance) and monitored at large scales (overall integrated GI performance and their impact on combined sewer overflows (CSOs), and 3) Cincinnati, OH with three study sites including …

Integrating virtual world with choice experiment method: case of residential stormwater management measures
… with LID techniques, particularly with rain gardens and permeable pavement. They had higher levels of familiarity with rain barrels. Therefore, there is a need for more educational programs that cover different types of LIDs, not just rain barrels.
