There is growing interest for the installation of green stormwater infrastructure (GSI) to improve control, increase infiltration stormwater, and receiving water body quality. Planning level tools are needed inform municipal scale decisions on type extent GSI apply. Here, a modified methodology developed EPA Storm Water Management Model (SWMM) create SWMM Low Impact Technology Evaluation (SWWM-LITE) that enables assessment control measure (SCM) performance with minimal input data...
Abstract High nighttime urban air temperatures increase health risks and economic vulnerability of people globally. While recent studies have highlighted heat mitigation effects vegetation, the magnitude variability vegetation-derived cooling differs greatly among cities. We hypothesize that is driven by vegetation density whose effect regulated aridity through increasing transpiration. test this hypothesis deploying microclimate sensors across eight United States cities investigating...
Semi-arid urban environments are undergoing an increase in both average air temperatures and the frequency intensity of extreme heat events. Within cities, different composition densities landcovers (ULC) influence local temperatures, either mitigating or increasing heat. Currently, understanding how combinations ULC temperature at block to neighborhood scale is necessary for mitigation plans, yet limited due complexities integrating high-resolution with spatial temporally microclimate data....
Abstract Coastal urban areas like New York City (NYC) are more vulnerable to pluvial flooding particularly because the rapid runoff from extreme rainfall events can be further compounded by co-occurrence of high sea-level conditions either tide or storm surge leading compound events. Present-day is a significant challenge for NYC and this expected become severe with greater frequency intensity storms rise (SLR) in future. In study, we advance NYC’s assessment present future exposure through...
Extensive data and computational requirements limit the application of existing urban hydrology models at municipal scales. Community-enabled Lifecycle Analysis Stormwater Infrastructure Costs (CLASIC) is a web-based deployment SWMM model with decoupled hydrologic hydraulic components to enable assessment larger This study comprehensively evaluates performance validity CLASIC for characterization responses against observed data. Furthermore, global sensitivity analysis used explore...
Abstract Urbanization alters the delivery of water and sediment to receiving streams, often leading channel erosion enlargement, which increases loading nutrients, degrades habitat, harms sensitive biota. Stormwater control measures (SCMs) are constructed in an attempt mitigate some these effects. In addition, stream restoration practices such as bank stabilization increasingly promoted a means improving quality by reducing downstream pollutant loading. Each unique combination SCMs results...

Abstract Many states are adopting more stringent nutrient load restrictions, requiring utilities to invest in costly improvements. To date, substantial research has been done independently assess the removal efficacy of wastewater treatment technologies and stormwater control measures. The analysis presented here provides a unique assessment by evaluating combinations reduction strategies across water supply, wastewater, sectors. A demonstration study was conducted 7812 cross‐sector urban...
This study investigates the role of parameter uncertainty on evaluation stormwater control measures. Specifically, several formal and informal Bayesian analysis techniques are linked with modified Fair Geyer model to predict effluent total suspended solids (TSS) concentrations from extended detention basins (EDBs). Moreover, a global sensitivity is performed identify most important parameters model. The results indicate that TSS removal in EDBs sensitive particle size distribution density...
