Review on inorganic pollutants in stormwater runoff of non-metal roofs

Frontiers in Environmental Chemistry, 2022
Metal roofs have always been in the focus of stormwater runoff contamination. However, other roofing materials are also suspected of releasing metals and other inorganic substances with stormwater runoff.

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI

Groundwater, EarlyView.
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

Managed Aquifer Recharge Operations and Design under Hydrologic Uncertainty

Groundwater, EarlyView.
Integrated hydrologic modeling uses dual ensembles of MAR operations and IES‐derived parameters to evaluate mounding, inundation, and transport risks under climate extremes. Exceedance‐probability metrics quantify environmental risks across the MAR impact zone, showing drain‐controlled mound limits, recovery effects, and pathways to interdunal and ...

Suspended solids in stormwater runoff from various urban surfaces [PDF]

, 2005
[Introduction]:Stormwater runoff from urban areas has long been identified as being a significant cause of poor water quality in creeks and rivers. Pollutants washed off urban surfaces include sediments, litter, organic matter, nutrients, heavy metals ...

How does imperviousness develop and affect runoff generation in an urbanizing watershed?

Fennia: International Journal of Geography, 2013
Imperviousness associated with urbanization remains one of the biggest challenges in sustainable urban design. The replacement of forests, marshlands, buffers, and wetlands with impervious surfaces, strongly influences hydrological processes in ...

Controlling construction stormwater runoff

, 2005
The U.S. Environmental Protection Agency (EPA) has long recognized stormwater runoff as one of the leading causes of impairment of streams, and as a result, developed Phase I stormwater requirements in 1990, which resulted in the first NPDES Stormwater ...

Stormwater capture as a Pathway to enhance groundwater recharge: A potential assessment in arid to semi-Arid urban landscapes

City and Environment Interactions
In semi-arid to arid regions, urban stormwater management practices (SMPs) can be used to capture runoff and enhance local groundwater recharge. This study develops a novel, transferable, easy-to-implement method that utilizes open public records and ...

The evaluation of stormwater runoff

Mokslas – Lietuvos ateitis / Science – Future of Lithuania
Conventional wastewater flow measurement techniques are difficult to apply for stormwater runoff. Therefore, a strong need for the new types of flow measurements is foreseen, especially in the existing urban areas. Water level was measured applying a hydrostatic level meter and flow was calculated according to typical hydraulic relationship.

The impacts of substrate and vegetation on stormwater runoff quality from extensive green roofs

, 2019
Green roofs are emerging as practical strategies to retain stormwater runoff and improve water environment quality of urban cities. However, the impacts of green roofs on stormwater runoff quality remains a topic of concern to urban planners and mangers.

First flush analysis of urban stormwater runoff from an urban catchment in Johor, Malaysia

MATEC Web of Conferences, 2018
An increase of pollutants that are present in the initial stage of stormwater runoff hydrograph compared to a later stage of runoff is defined as a first flush phenomenon. This study aims to investigate the occurrence of first flush from samples of urban
