The first flush load of urban surface runoff
Water Research, 1998The treatment of urban surface runoff is steadily becoming common practice. Good management of treatment works requires an understanding of the first flush phenomenon of wet weather flow in urban drainage systems. The objective of this paper is to analyse evidence for the existence and nature of the first flush load of pollution input into drainage ...

Implications of a kinematic wave model for first flush treatment design
Water Research, 2006A deterministic model was developed to predict pollutant mass first flush and to utilize it for better design of best management practices (BMPs) that focus on treating the first flush. The model used the kinematic wave equation to calculate flow and mass transport, and erosion equations to calculate pollutant concentrations, which were assumed to be ...

Redefining the stormwater first flush phenomenon
Water Research, 2010The first flush in urban runoff has been an important, yet disputed phenomenon amongst many researchers. The vast differences in the evidence could be solely due to limitations of the first flush current definition and the approach used for its assessment.

First flush in a combined sewer system
Chemosphere, 2008Pollutant first flush was examined in an urban catchment with area of 12.7 ha and drained by a combined sewer system located in northern Italy. A total of 23 rainfall-runoff events were monitored and 281 samples were analyzed. The selected quality parameters were biochemical oxygen demand, chemical oxygen demand, suspended solids, settleable solids ...

Effect of the first-flush phenomenon on the quantification of microplastics in rainwater
Marine Pollution Bulletin, 2023Precipitation of airborne microplastics (MPs) by rainfall is one of the major transport pathways of MPs from land-to-marine. While most studies examining wet precipitation of MPs collect surface runoffs, direct investigations of MPs in rainwater are hardly reported. In this study, high-frequency and direct rainwater sampling methodology considering the

Journal of Hydrologic Engineering, 2010
The goals of storm-water management have shifted from a flood control to a holistic and sustainable strategy, emphasizing the relationship between rainfall event size and pollutant loadings. The first flush concept is the first part of a rainfall event that contains the largest pollutant loading. Questions have been raised on the concept's validity for

First Flush of Organics in Highway Runoff
Global Solutions for Urban Drainage, 2002Stormwaters from three highway sites were monitored over two wet seasons for organics, Chemical oxygen demand, oil and grease and polyaromatic hydrocarbons (PAHs) were measured. The sites exhibited a first flush in most cases for most parameters. The mass first flush ratio (the ratio of the normalized transported mass of pollutant to the normalized ...

Seasonal first flush phenomenon of urban stormwater discharges
Water Research, 2004California's climate, typified by winter and spring precipitation and summer drought, is often called a Mediterranean climate, and creates a long period for pollutant build-up. The initial storms of the winter season usually have higher pollutant concentrations, which is called a seasonal first flush.

First Flush Stormwater Runoff from Highways
Bridging the Gap, 2001Stormwater is now receiving attention from regulatory agencies and has become an important component in watershed planning. In many cases, pollutant mass emissions from stormwater exceed those from wastewater treatment plants. Land use has been identified as an important parameter in predicting stormwater quality.
