Draft Ordinance Regarding Impervious Surface Coverage
, 2000 This is a collection of impervious surface coverage ordinances and analyses done for Spring Lake. The purpose of this study was to determine impervious surface coverage as a basis for developing impervious surface controls for new and redeveloped residential and non-residential development.

A Soil and Impervious Surface Adjusted Index for Urban Impervious Surface Area Mapping
Photogrammetric Engineering & Remote Sensing, 2021Index-based methods are widely applied to urban impervious surface area (ISA) mapping, but the confusion between ISA and soil remains unsolved. In this article, the near-infrared (NIR)-blue bands were selected as feature space by analyzing the spectra from the US Geological Survey spectral library, and a simple impervious surface ratio index (ISRI ...

The monitoring of contaminated impervious planar surfaces
Journal of Radiological Protection, 1999The responses of several types of surface contamination monitor have been investigated for three typical working surfaces contaminated by three radionuclides commonly used in diagnostic or analytical biomedical applications. Of the three radionuclides, 99mTc is an intermediate-energy gamma emitter, 125I decays by electron capture, emitting low-energy x-

A Comparison of Approaches to Impervious Surface Characterization
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Impervious surface estimates derived from different modeling approaches and data types were compared to highly accurate and precise planimetric calibration and validation data. A linear regression model using population density and percent land cover class per unit area produced the most accurate results, with an overall RMSE of 3.2% for the 82 census ...

Adsorption of Phthalates on Impervious Indoor Surfaces
Environmental Science & Technology, 2017Sorption of semivolatile organic compounds (SVOCs) onto interior surfaces, often referred to as the "sink effect", and their subsequent re-emission significantly affect the fate and transport of indoor SVOCs and the resulting human exposure. Unfortunately, experimental challenges and the large number of SVOC/surface combinations have impeded progress ...

Change of Impervious Surface of Chengdu City, China
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Impervious surfaces have become the most intuitive indicator in the process of urbanization. Timely and accurate information on impervious surfaces from remote sensing images is essential. It not only helps us understand the process of land use/cover change, but also the influences on human society and the environment.

Rural impervious surfaces extraction from Landsat 8 imagery and rural impervious surface index
SPIE Proceedings, 2014There is an increasing need to understand pattern and growth of impervious surfaces in rural regions. However, studies using remote sensing of impervious surfaces have often focused on mapping impervious surfaces in urban regions with less emphasis placed on the rural impervious surfaces. In this paper, we proposed a new index, Rural Impervious Surface

Remote sensing of impervious surfaces: A review
Remote Sensing Reviews, 2001One of the emerging areas of scientific interest in the control of non‐point‐source pollution (NPS) is the detection and analysis of impervious surfaces within watersheds. NPS runoff from urban surfaces is now a leading threat to water quality and the percentage of impervious surface within a particular watershed has been recognized as a key indicator ...

Assessment of Impervious Surface Estimation Techniques
Journal of Hydrologic Engineering, 2009Impervious surfaces have been identified as a reliable indicator of the impacts of development on water resources. Research has found that imperviousness has a direct effect on local surface water as well as indirect effects on downstream receiving waters.

The Impact of Impervious Surface on Water Quality and Its Threshold in Korea
Water (Switzerland), 2016 The change in the impervious-pervious balance has significantly altered the stream water quality, and thus the threshold of the impervious surface area in the watershed has been an active research topic for many years.
