To minimize that impact, the design of green\u003Cbr \/\u003E\r\ninfrastructure for stormwater control mimics the pre-construction hydrology of a\u003Cbr \/\u003E\r\ndeveloped area using best management practices (BMPs) designed with three\u003Cbr \/\u003E\r\nprimary goals: minimizing runoff flowrate to reduce flooding and erosion; maximizing\u003Cbr \/\u003E\r\npollutant deposition to reduce discharge to natural waterways including\u003Cbr \/\u003E\r\ngroundwater; and increasing groundwater recharge and with an added filtration\u003Cbr \/\u003E\r\ncomponent.\u003Cbr \/\u003E\r\nBecause stormwater BMP permitting can result in differences in prioritized design\u003Cbr \/\u003E\r\nparameters, inconsistent efficiency measurements, and an extremely wide range of\u003Cbr \/\u003E\r\nquantification methods, this work focused on bringing uniformity to the design and\u003Cbr \/\u003E\r\nperformance of the vegetated slope that is designed for stormwater control. In this\u003Cbr \/\u003E\r\nstudy, an analytical model was developed to incorporate both overland flow and soil\u003Cbr \/\u003E\r\ninfiltration in the BMP\u2019s partially saturated soils to optimize designs for lower\u003Cbr \/\u003E\r\nstormwater discharge volumes and longer residence time. Additionally, field and\u003Cbr \/\u003E\r\nlaboratory studies were performed to study the transport and deposition of solid\u003Cbr \/\u003E\r\nphase contaminants (soil and rubber) to quantify solids deposition profiles\u003Cbr \/\u003E\r\nthroughout the length of a vegetated slope. Dissolved heavy metal transport through\u003Cbr \/\u003E\r\nthe vegetated slope was evaluated based on the adsorption characteristics of the\u003Cbr \/\u003E\r\ndeposited sediment profile of the BMP. Results showed that the flow rate could be\u003Cbr \/\u003E\r\nreduced by up to 19% in silty sandy soils in unsaturated conditions when accounting\u003Cbr \/\u003E\r\nfor infiltration. Further, 99% of solids were deposited in the first 2 meters of a\u003Cbr \/\u003E\r\nvegetated slope, which agreed well with modeled trapping efficiencies based on\u003Cbr \/\u003E\r\nparticle diameter and density. Adsorption analysis showed that Piedmont soils\u003Cbr \/\u003E\r\nsorbed relatively small concentrations of heavy metals; however, incorporating even\u003Cbr \/\u003E\r\nsmall percentages (by mass) of a highly sorbent component (activated carbon) in\u003Cbr \/\u003E\r\nthe soil regime increased both infiltration and adsorptive capacity, substantially\u003Cbr \/\u003E\r\nincreasing the filter strip\u2019s performance.\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EGREEN INFRASTRUCTURE DESIGN: PERFORMANCE OF VEGETATED FILTER STRIPS OPTIMIZED FOR INFILTRATION AND SORPTIVE AMENDMENTS\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/strong\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"GREEN INFRASTRUCTURE DESIGN: PERFORMANCE OF VEGETATED FILTER STRIPS OPTIMIZED FOR INFILTRATION AND SORPTIVE AMENDMENTS"}],"uid":"27707","created_gmt":"2024-04-05 00:43:27","changed_gmt":"2024-04-05 00:44:29","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-04-17T10:00:00-04:00","event_time_end":"2024-04-17T12:00:00-04:00","event_time_end_last":"2024-04-17T12:00:00-04:00","gmt_time_start":"2024-04-17 14:00:00","gmt_time_end":"2024-04-17 16:00:00","gmt_time_end_last":"2024-04-17 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"(Hybrid) SEB 122 and Zoom ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
