Measuring Impervious Surfaces for Non-point Source Pollution Modeling
The US EPA has reported non-point source pollution (NPS), which includes eroded sediments, toxic contaminants, nutrients, debris, and other pollutants, to be the number one threat to surface water quality nationwide. Numerous studies have established a direct relationship between the amount of impervious surface within a watershed and pollution of its surface waters. However, without detailed d...
متن کاملModeling pollutant release from a surface source during rainfall runoff.
Though runoff from manure spread fields is recognized as an important mode of nonpoint-source pollution, there are no models that mechanistically describe transport from a field-spread manure-type source. A mechanistic, physically based model for pollutant release from a surface source, such as field-spread manure, was hypothesized, laboratory tested, and field-applied. The primary objective of...
متن کاملStormwater Runoff Pollutant Loading Distributions and Their Correlation with Rainfall and Catchment Characteristics in a Rapidly Industrialized City
Fast urbanization and industrialization in developing countries result in significant stormwater runoff pollution, due to drastic changes in land-use, from rural to urban. A three-year study on the stormwater runoff pollutant loading distributions of industrial, parking lot and mixed commercial and residential catchments was conducted in the Tongsha reservoir watershed of Dongguan city, a typic...
متن کاملSource Term Estimation of Pollution from an Instantaneous Point Source
The goal is to develop an inverse model capable of simultaneously estimating the parameters appearing in an air pollution model for an instantaneous point source, by using measured gas concentration data. The approach taken was to develop the inverse model as a non-linear least squares estimation problem in which the source term is estimated using measurements of pollution concentration on the ...
متن کاملPollutant loads of surface runoff in Wuhan City Zoo, an urban tourist area.
The pollutant loads of surface runoff in an urban tourist area have been investigated for two years in the Wuhan City Zoo, China. Eight sampling sites, including two woodlands, three animal yards, two roofs and one road, were selected for sampling and study. The results indicate that pollutants ranked in a predictable order of decreasing load (e.g. animal yard > roof > woodland > road), with an...
