Pesticide runoff from impervious surfaces is a significant cause of aquatic contamination and ecologic toxicity in urban waterways. Effective mitigation requires better understanding and prediction of off-site transport processes. Presented here is a comprehensive study on pesticide washoff from concrete surfaces, including washoff tests, experimental data analysis, model development, and appli...

Rapid urbanization has occurred in northwestern China, threatening the sustainability of its fragile dryland ecosystems. A lack of precise urban land-cover information has limited our understanding on the urbanization in the dryland. Here, we examined urban land-cover changes from 2000 to 2014 in 21 major cities that comprise over 50% of the developed land in arid China, using Landsat Enhanced ...

Remote sensing data were utilized to assess urban land cover and its thermal characteristics through mapping sub-pixel impervious surfaces and assessing thermal infrared images. Landsat imagery was used to calculate variation in urban imperviousness from 1995 to 2002 in the Tampa Bay watershed, Florida. The urban-rural boundary and urban development density were defined by selecting certain imp...

As forests, agricultural fields, and suburban and urban lands are replaced with impervious surfaces resulting from development, the necessity to recover green space is becoming increasingly critical to maintain environmental quality. Vegetated or green roofs are one potential remedy for this problem. Establishing plant material on rooftops provides numerous ecological and economic benefits, inc...

Introduction As the population of California continues to grow, new communities emerge and existing ones expand. Impervious surfaces, including roads, houses, and commercial buildings, are a hallmark of this urban expansion. These impervious surfaces have significant impacts on local watersheds. Impervious cover (IC) affects the hydrology, chemistry, and biotic integrity of aquatic ecosystems. ...

a r t i c l e i n f o With the constant proliferation of computational power, our ability to develop hybrid classifiers has improved. Hybrid classifiers integrate results from multiple algorithms and often improve classification accuracy. In this paper, a hybrid classification framework was used to evaluate two research hypotheses: i) can manipulated results from prior classifiers (" intermedia...

Different wipe materials and wetting agents have been traditionally used to collect pesticide residues from indoor surfaces in human exposure assessments. Such methods were developed to estimate human pesticide exposure through skin contact. From an environmental point of view, wiping methods may be also applied to predict the runoff potential of pesticides on urban impervious surfaces. Since l...
