Sediment samples were collected to delineate the distribution of contaminants along the central California coast. Sampling included a variety of Canyons and shelf/slope areas to evaluate contaminant transport patterns and potential delivery to Canyons and the continental slope to a depth of 1200 m. Sediments were collected and analyzed for organic contaminants using standard techniques of the N...

City centers have to cope with an increasing amount of air pollution. The supply fresh is crucial yet difficult ensure, especially under stable conditions the atmospheric boundary layer. This case study used PArallelized Large eddy simulation (LES) Model PALM investigate wind field over urban lake that had once been built as a designated corridor for city center Münster, northwest, Germany. mod...

Deploying solar reflective materials on urban surfaces is known as an effective heat mitigation strategy. Several studies have shown their cooling impacts; however, most of them focused rooftops rather than facades. The novelty this paper related to exploring the impact each façade orientation corresponding microclimate and energy balance. High albedo were implemented facades with different ori...

As cities are extremely vulnerable to the impacts of climate change, they fundamental in addressing these changes. However, streets, which external spaces accessed by citizens daily life, play an important role improving urban environment and public health. This study considered Busan South Korea as a case investigate street canyons, including canyon geometries tree configurations, old, present...

Recent studies indicate the necessity of addressing traffic-related air pollution in urban environments, as street canyons are known for their lack natural ventilation and increased levels. To address this issue, numerous have been conducted on different aspects (e.g. aspect ratio, orientation height variation) impact dispersion/dilution performance canyons. Despite studies, information remains...

Submarine canyons are dramatic and widespread topographic features crossing continental and island margins in all oceans. Canyons can be sites of enhanced organic-matter flux and deposition through entrainment of coastal detrital export, dense shelf-water cascade, channelling of resuspended particulate material and focusing of sediment deposition. Despite their unusual ecological characteristic...

Low Earth Orbit (LEO) satellites are an essential complement of the cellular radio infrastructure, especially the Universal Mobile Telecommunications System (UMTS), for mobile (pedestrian and, more important, vehicular) access to the Internet in sparsely populated areas, where high bandwidth UMTS cells cannot be economically deployed. LEO users would eventually switch between the satellite segm...
