BACKGROUND Evidence from numerous studies suggests that salt intake is an important determinant of elevated blood pressure. Robust data about salt consumption among adults in Bangladesh is sparse. However, much evidence suggests saline intrusion due to sea level rise as a result of climate change exposes more than 20 million people to adverse effects of salinity through the food and water suppl...

Salinity intrusion is a significant issue in the San Francisco Bay Delta because this estuary contributes substantially to fresh water supply for much of northern California. Traditionally, salinity along the estuary has been measured using monitoring instruments installed at various locations within the Sacramento-San Joaquin River Delta system, and these measurements are used to predict futur...

Subtidal adjustment of estuarine salinity and circulation to changing river flow or tidal mixing is explored using a simplified numerical model. The model employs tidally averaged, width-averaged physics, following Hansen and Rattray, extended to include 1) time dependence, 2) tidally averaged mixing parameterizations, and 3) arbitrary variation of channel depth and width. By linearizing the vo...

The majority of this course has focused on large scale climate and human health applications. The paper presented here, however, is an example of a smaller scale application of statistics to a geo-environmental issue. Researchers intend to model groundwater in an approximately 200 kilometer (km) by 300 km area around the city of Winnipeg, Manitoba, Canada. The study area is located on the easte...

The energetic performances of seven SOD or RHO-topology ZIFs, with zinc or cobalt metal cation (ZIF-8, ZIF-90, Zn(dcim)2-SALE, ZIF-67, ZIF-7, ZIF-71, ZIF-11) were evaluated using water intrusion-extrusion under high pressure. The relationship between the structural parameters (in particular the pore system SOD or RHO, the type of linker, the metal cation nature) and the intrusion pressure was s...

Soil salt-water dynamics in the Yangtze River Estuary (YRE) is complex and soil salinity an obstacle to regional agricultural production ecological environment YRE. Runoff into sea reduced during impoundment period as result of water-storing process Three Gorges Reservoir (TGR) upper reaches River, which causes serious seawater intrusion. a problem due shallow saline groundwater under intrusion...
