The accumulation of sediment in aquatic environments can lead to an increase flood risk due raised floodplains and water levels. Electromagnetic modeling techniques, such as Time Domain (TDEM) resistivity or lithological conductivity contrast, be utilized detect changes the subsurface. In this study, we investigated use TDEM hazard mitigation schemes by developing a 1-D forward program for cent...

Most salmonid taxa have an anadromous life history strategy, whereby fish migrate to saltwater habitats for a growth period before returning to freshwater habitats for spawning. Moreover, several species are characterized by different life history tactics whereby resident and anadromous forms may occur in genetically differentiated populations within a same species, as well as polymorphism with...

The site under study covers an area of 273 km in the Oristano plain on the west coast of Sardinia (Italy). Since 1950 the plain, formed during the Quaternary by alluvial deposits, has been under intensive cultivation and is an important dairy farming centre. In the coastal region, the large number of wells (25,000 tapped and not) some very close to each other, has resulted in over-exploitation ...

Methods to predict onset of cardiopulmonary (CP) decompression sickness (DCS) would be of great benefit to clinicians caring for stricken divers. Principal dynamic mode (PDM) analysis of the electrocardiogram has been shown to provide accurate separation of the sympathetic and parasympathetic tone dynamics. Nine swine (Sus scrofa) underwent a 15-h saturation dive at 184 kPa (60 ft. of saltwater...

In metropolitan regions made up of multiple independent jurisdictions, adaptation to increased coastal flooding due to sea level rise requires coordinated strategic planning of the physical and organizational approaches to be adopted. Here, we explore a flexible method for estimating physical adaptation costs along the San Francisco Bay shoreline. Our goal is to identify uncertainties that can ...

Viruses are an abundant and active component of marine sediments and play a significant role in microbial ecology and biogeochemical cycling at local and global scales. To obtain a better understanding of the ecological characteristics of the viriobenthos, the abundance and morphology of viruses and the diversity and community structure of T4-type phages were systematically investigated in the ...

Abstract Saltwater intrusion in estuaries has become a serious environmental problem, such as the Pearl River estuary (PRE). In this study, we used fully validated three-dimensional hydrodynamic model EFDC to numerically investigate saltwater PRE during dry season of 2007-2008. Based on measured salinity, an abnormally strong occurred Humen Channel February 2008. The twice month varying extents...
