The Groundwater Challenge

2008
Groundwater is the most extracted natural resource in the world. It provides more than half of humanity’s freshwater for everyday uses such as drinking, cooking, and hygiene, as well as thirty percent of irrigated agriculture and industrial development.

Groundwater control by groundwater lowering

Geological Society, London, Engineering Geology Special Publications, 1986
ABSTRACT When an excavation is to extend beneath the water table the ground conditions may be improved by lowering the level of the water table beneath the proposed base of the excavation. Groundwater lowering is accomplished by removing water from the ground at a faster rate than recharge can occur.

Groundwater in slopes

2012
Groundwater flows in the pores and fractures of soils and rocks, driven by changing mechanical and environmental boundary conditions, for example air temperature, humidity, and precipitation. Because the groundwater environment continuously changes, the steady--state condition is only a theoretical concept: the movement of water in soils and rocks is ...

Groundwater Pricing and Groundwater Markets

2018
There are several general principles involved in assessing the economic value of water and the costs associated with its provision. First, an understanding of the costs involved with the provision of water, both direct and indirect, is key. Second, from the use of water, one can derive a value, which can be affected by the reliability of supply, and by

Groundwater Age and Groundwater Age Dating

Annual Review of Earth and Planetary Sciences, 2008
A new way of thinking about groundwater age is changing the field of groundwater age dating. Following a rigorous definition of age, a groundwater sample is seen not as water that recharged the flow regime at a point in the past, but as a mixture of waters that have resided in the subsurface for varying lengths of time.

Norovirus Detection in Groundwater

Food and Environmental Virology, 2009
Waterborne disease outbreaks associated with groundwater consumption have been reported in different countries. Noroviruses are considered emerging pathogens, which cause gastroenteritis in all age groups worldwide and numerous outbreaks of noroviral gastroenteritis have been ascribed to contaminated drinking water.

Groundwater-runoff relationships

CATENA, 1980
Summary Stable environmental isotope ( 2 HH, 8 O)O) techniques were applied to an Alpine watershed of 18.7 km 2 and 670–1801 m a.s.l. From this example some insights into the runoff generation in a natural hydrologic system are developed. Isotopic hydrograph separations into direct and indirect runoff fractions, based on these techniques, show ...
