SWMM stormwater quality model developed to assess the performance of best management practices: a case study of the town of Jasper in Canada

Stormwater quality control is critical for the safety of aquatic life of receiving waterbodies. In the Town of Jasper, Alberta, Canada, a stormwater management scheme was used to assess street sweeping and infiltration trenches' performance to reduce total suspended solids loads. The results revealed that a combination sweeping/trench control strategy would yield the highest TSS removal rate of up to 51%.

Discharge and fate of biocide residuals to ephemeral stormwater retention pond sediments

Retention ponds are part of stormwater control that preserves water and partially pollutes. However, it is uncertain which percentage of biocides leached from facades makes it to a pond and how biocides are retained inside ponds, though biocides may have negative environmental impacts. Our findings are location specific, but they indicate that biocide retention in ponds is limited, environmental entry pathways are diverse, and that biocide use should be limited at its source.

Strategies to Encourage Adoption of Stormwater Pond Best Management Practices (BMPs) by Homeowners

Man-made ponds can be a convenient way to gather, store, and treat stormwater runoff in residential areas. This 9-page fact sheet lists several effective management tips for reducing stormwater pond pollution. The authors suggest that Extension educators use this BMPs to encourage residents to adopt these BMPs based on a survey of people who live near stormwater ponds.

Using Machine Learning to Improve Performance of a Low-Cost Real-Time Stormwater Control Measure

During expansion, the transformation of natural land cover to impervious surfaces increases stormwater runoff. Stormwater Control Measures are used to control water quantity and quality by improving the hydrologic cycle that has been altered by development. SCMs are often equipped with an outflow pipe to handle overflows or to control the release of water detained when infiltration isn't possible. RTC help SCMs be more reliable by dynamically controlling outflows to adjust to environmental conditions. This research used machine learning techniques to develop a forecasting strategy for the introduction of low-cost RTC on a programmable gate of a multi-stage basin in southeastern Pennsylvania's programmable gate. Multiple linear regression and long-term memory were among the popular data science algorithms tested. Multiple linear regression and long-term memory were among the many popular data science algorithms evaluated, including multiple linear regression and long-term memory.

Constructing an inventory for fast screening of hydraulic and hydrologic performance of stormwater control measures

Abstract: Stormwater management in cities can be both cost-effective and cost-effective. Unlike underground drainage systems, they need space on the city surface and therefore must be included in initial urban planning and design drawings. We developed a software for estimating multiple performance indicators of a wide range of SCMs and applied it to Danish meteorological conditions. The methodology includes consulting with prospective end users, constructing an SWMM model for each SCM type and selecting appropriate parameter ranges, running multiple simulations for each type of parameter space, and then post-processing the results using python and PySWMM.

Florida’s urban stormwater ponds are net sources of carbon to the atmosphere despite increased carbon burial over time

Abstract In urban watersheds, stormwater ponds are engineered ecosystems that are intended for flood control and sediment retention. We investigated the potential effect of stormwater ponds on regional carbon cycling by coupling carbon burial rates and fluxes of carbon dioxide and methane gases in five locations over a age range of 14 to 34 years. Stormwater ponds can be net carbon sources and must be considered for national and global carbon models, according to Comparing carbon burial to gas flux.

Experimental Research on the Treatment of Stormwater Contaminated by Disinfectants Using Recycled Materials—Hemp Fiber and Ceramzite

Pollution caused by the use of disinfectants in public spaces is a relatively recent form of environmental contamination. Early findings revealed a sevenfold rise in the use of disinfectants to clean outdoor spaces during the COVID-19 pandemic of 2020u20132021, as well as a corresponding rise in environmental pollution. Typically, disinfectants are carried to surface waters where they react with various components to create harmful substances after entering stormwater systems. According to the amounts of disinfectants used, stormwater pollution indicators will change based on the amount of disinfectants used, according to our investigation. In laboratory experiments conducted with hemp fiber and ceramzite, in which filtering stormwater samples contaminated with different amounts of disinfectants showed declines in the amount of active chlorine from 2. 93 ppm to 1. 0 ppm. This paper publishes the findings of our study into the effects of disinfectants on stormwater.

Inactivation of antibiotic resistant bacteria from stormwater runoff using UVA/LED and its potential risks

At 8 mW/cm2 of UVA/LED for 180 mins, results showed that ARB inactivation efficiencies had reached 6. 31 log reductions. At 50 mg/L of SS, the most effective inactivation efficiencies were 3. 56 log decreases, with increasing SS levels. Initial pH had no effect on ARB inactivation by UVA/LED irradiation. A low initial bacteria concentration was not necessarily associated with good ARB activation, according to ARB Inactivation. ARB was barely apparent after 12 hrs of dark repair, and the transfer frequency of the kanamycin resistance gene was increased to 5. 43 u22124.

A Decision Support Matrix for Water Quality Based Stormwater Management

Water quality is determined by the watershed's characteristics, according to the decision support matrix used in the construction of the e-monitoring system. The comparison of the developed matrix and the sampling findings revealed that the assumed connections did not hold on a small catchment, and that further testing of relationships between survivate and traditional water quality parameters needs to be carried out.
