Characteristic of Stormwater Quality Using BIOECODS in JKR Pilot Projects

The success of the Bio-Ecological Drainage System in terms of improving water quality is particularly important because it represents one of the key goals of the sustainable drainage system. Stormwater samples were collected at six sampling points identified within the study area since June 2020, resulting in a Certificate of Practical Completion award being awarded. All of the parameters were also classified as meeting Class IIA and Class IIB, National Water Quality Standard for Malaysia, according to the local authority before the runoff is discharged via discharge point approved by the Local Authority.

Analytical and Experimental Assessment of Regulating Volume of the Stormwater Storage Tanks for Rains of Constant Intensity

Extreme weather around the world is a result of climate change, for example extreme rainfall. Detention-retention systems are a cost-effective way of reducing peak flow and equalizing flow rates from stormwater runoffs. In the paper, the theoretical study and the experimental investigation of the storm water storage tanks' regulative volume are presented. The experimental setup was planned and implemented - the model of a runoff basin and rainfall was used to perform experimental studies in order to establish the theoretical model.

New Methodology for Efficient Management of Chloramine Concentrations in Stormwater Systems

Polluted urban stormwater effluents pose a threat to receiving waterways. Many municipalities are concerned about point-source releases of chloramine-treated drinking water that reach the drainage system through outdoor and industrial water uses, according to several municipalities. As a result of point-source leaks occurring somewhere in the stormwater system, a new approach to produce water quality maps was introduced that shows the concentrations of chloramine at the system outlet. Using the outputs of the stormwater hydraulic and quality models, the Bayesian Kriging Method was used to generate the water quality maps. For dry weather flows, the results indicated that chloramine levels were over the entire basin, but only a design storm of a 10-year return period produced chloramine concentrations below regulation discharge limits. Overall, concentration maps are a one-of-a-kind device that can help system operators tackle stormwater pollution without performing time- and labour-intensive simulations.

Analysis of Stormwater Drainage Network of the Central Zone in the Surat City by Using SWMM 5.1 Software

Flooding incidents in India have surged in recent years, particularly in major cities. Urban flooding primarily occurs as a result of rapid urbanization, low rates of infiltration, and a sloppy drainage network that does not have adequate stormwater drainage infrastructure. Stormwater drainage plays a vital role in moving rain from urban areas to the outlet site. None of the reviewed reports have reported on urban SWDN of the Central Zone in Surat City. In the new report, an analysis of SWDN of the CZ in the Surat City is performed using SWMM software. According to the aforesaid report, the number of junction nodes flooded, which are corresponding to 2 and 5 years return times - is 72 and 99, respectively. Maximum flooding discharge and duration of floods at these junctions have also been found to be less than that at the J145 junction, but other junctions have been flooded, but maximum flooding discharge and duration of floods at these junctions have been found to be less than the J145 junction.

Sustainable In-Ground Permeable Reactive Filter for the Treatment of Urban Stormwater Runoff

Surface water contamination problems have existed for a long time in Chicago's impermeable landscapes and nonpoint source pollution associated with dense urban environments. Due to elevated E. Coli levels, the City of Chicago now has to perform same day testing for urban beaches to warn swimmers of potential health risks and beach closures. A viable option to remove the pollutants associated with urban runoff and improve the water quality of Chicago's beaches may be in-ground reactive stormwater filters.

Impacts of climate change on IDF curves for urban stormwater management systems design: the case of Dodola Town, Ethiopia

Climate change impacts are one of the global challenges that change the frequency and frequency of rainfall. In this report, the rainfall intensityu2013u2013frequency curves for urban stormwater drainage infrastructures under climate change have been updated, as well as flood risk reductions. To measure the variation in the rainfall intensity, the future IDF curves for the periods and two GCMs were developed and compared to the new IDF curves. Rain intensities for future climate conditions will be different from the previous period for all durations and return periods. Urban flooding in the future will rise as a result of climate change, according to the IDF's links. This report will help to better understand the effects of climate change on rainfall IDF relationships, as well as the design of new and future stormwater management systems in Dodola, Ethiopia.

Stormwater runoff reduction simulation model for urban flood restoration in coastal area

Many coastal cities are affected by urban growth and short-term heavy flooding, which can be detrimental to many coastal cities. Urban floods caused by expanding impervious areas due to urban growth and short-term heavy precipitation have adversely affected many coastal cities. During the rain season, notably, Seoul, one of the coastal cities that sees intense urban floods, suffers annually from urban floods. Consequently, we estimated flood-vulnerable areas in Seoul as target areas for which green infrastructure planning could be carried out using the Stormwater Runoff Reduction Module, which helped to minimize the effects of urban floods in Seoul. Analyses were estimated in lowering the runoff amount and peak time delay effect by modeling simulation using the SRRM. The decline in peak discharge per unit area in Gangbuk district, followed by Dobong and Gangdong districts, was in comparison. The findings of this research, according to us, can greatly increase the effectiveness of urban flood restoration and green infrastructure planning in coastal cities.

Evaluating the Thiessen polygon approach for efficient parameterization of urban stormwater models

In a sewershed in the City of Pittsburgh, the functionality of this approach is tested using the EPA's Storm Water Management Model to simulate pipe flow. The number of nodes used to build the model was tested to determine the model's effectiveness, which was a result of the number of nodes used to produce the model. When randomly reducing the number of nodes used to build the model, no statistical differences were found in model results. Based on our findings, the Thiessen polygon approach can be used to produce urban stormwater models and produce good pipe flow simulations even for sewer data limited scenarios.

The Occurrence of Glyphosate and its Degradation Products in the Urban Stormwater: A Short Review

Water pollution is now one of the twentieth century's biggest environmental challenges, due to urbanization and industrialization. The investigation of such pesticides and urban stormwater in recent decades is vital to understand how urban, suburban, and industrialized areas can influence environmental quality. Scientific interest in stormwater chemical characterization has increased lately with the aim of determining their impacts on the environment and potentially making it potable water.
