Reliability analysis of green roofs under different storm scenarios
… flooding and water quality due to changes in runoff caused by increasing impervious area. Green infrastructure offers an alternative method of runoff reduction, by using natural processes to infiltrate, store, and treat runoff at its source. In particular, green roofs can promise multiple …

Vegetated Swales in Urban Stormwater Modeling and Management
Despite the runoff reduction efficiencies recommended by various regulatory agencies, minimal research exists regarding the ability of vegetated swales to simultaneously convey and reduce runoff. This study assessed the effect water quality swales distributed among upstream sub-watersheds had on …

Using Bioretention Retrofits to Achieve the Goals of Virginia's New Stormwater Management Regulations
… stormwater regulations involve the use of the Runoff Reduction Method (RRM), which requires the product of the peak flow rate and runoff volume (Q*RV) from the one-year storm event in the post-development condition to be reduced to eighty percent of the pre-development Q*RV to protect against …

EFFECT OF MAJOR FACTORS ON BIOSWALE PERFORMANCE AND HYDROLOGIC PROCESSES FOR THE CONTROL OF STORMWATER RUNOFF FROM HIGHWAYS
… and roadways are the major source of stormwater runoff due to their prevalence and large non-permeable surface area. Best Management Practices (BMPs) such as bioswale provide effective on-site management and control of stormwater runoff from linear infrastructure such as highways. Many factors …

Applicability of Stormwater Best Management Practices in the Virginia Coastal Plain
The Virginia Runoff Reduction Method (RRM) was adopted in 2014 as a compliance tool for evaluation of stormwater volume and quality, and necessitates use of urban stormwater best management practices (BMPs) to meet regulatory standards. Coastal Virginia is characterized by flat terrain, shallow …

Optimization of BMP Selection for Distributed Stormwater Treatment Networks
… areas of highly concentrated pollutant runoff, etc. as well as economics, such as installation and operation and maintenance cost must be considered. Due to these multiple competing selection criteria and regulatory requirements, selection of optimal configurations of BMPs by manual …

Distributed surface-subsurface modelling approach for evaluating the impact of rain gardens on steep terrain
… one of the effective approaches to reduce 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 …

Hydrological assessment and modelling of the River Fani Catchment, Albania
… deforestation, afforestation and provision of runoff attenuation systems). The results suggest that the changes in vegetation cover (apart from farming practices) are not considerably extensive in the Catchment between 1984 and 2000. It was observed that afforestation as a flooding mitigation …
