One of the major impacts associated with unplanned rapid urban growth is the decrease of urban vegetation, which is often replaced with impervious surfaces such as buildings, parking lots, roads, and pavements. Consequently, as the percentage of impervious surfaces continues to increase at the expense of vegetation cover, surface urban heat island (SUHI) forms and becomes more intense. The Colo...

In the Pacific Northwest of the United States, adult coho salmon (Oncorhynchus kisutch) returning from the ocean to spawn in urban basins of the Puget Sound region have been prematurely dying at high rates (up to 90% of the total runs) for more than a decade. The current weight of evidence indicates that coho deaths are caused by toxic chemical contaminants in land-based runoff to urban streams...

Urban stormwater with large impervious (paved) areas often produces runoff with a variety of contaminants. Although southern California is among the most urbanized coastal areas in the United States, the effect of rainfall variations on washoff efficiency of contaminants from pervious and impervious surfaces is largely unknown. The goal of this study was to investigate the effect of varying rai...

Understanding the impacts of climate change on people and the environment requires an understanding of the dynamics of both climate and land use/land cover changes. A range of future climate scenarios is available for the conterminous United States that have been developed based on widely used international greenhouse gas emissions storylines. Climate scenarios derived from these emissions stor...

A major objective of ecology is to understand how ecological processes limit population connectivity and species' distributions. By spatially quantifying ecological components driving functional connectivity, we can understand why some locally suitable habitats are unoccupied, resulting in observed discontinuities in distribution. However, estimating connectivity may be difficult due to populat...

Urbanization, as a result of anthropogenic activities, reduces the vegetated and green spaces thereby increases impervious surfaces in cities. This turn surface temperature cities when compared to rural regions resulting formation urban heat island. Especially, under-developed countries, it is very crucial obtain timely accurate information on trend its development due higher increasing rate po...

As the capital city of China, Beijing has experienced unprecedented economic and population growth dramatic impervious surface changes during last few decades. An application classification method combining spectral textural features based on Random Forest was conducted to monitor spatial temporal Beijing’s surfaces. This strategy achieved excellent performance in extraction complex urban areas...

The presence of impervious surfaces in catchments interferes with the natural process infiltration, which has a marked influence on hydrological cycle, affecting base flow rivers and increasing surface runoff magnitude flood flows. Like many Latin American cities, Loja (located southern Ecuador) experienced significant rates urban growth recent years, catchment where it belongs. aim this study ...
