Arctic, Antarctic, and Alpine Research, Vol. 43, No. 3 (August 2011), pp. 364-379 (16 pages) Subsurface flow pathways of groundwater-fed streams were characterized on a floodplain terrace of the ...

Groundwater flow modelling is a critical tool in the management and protection of water resources, especially in the context of both confined and unconfined aquifers. Confined aquifers, bounded by ...

Permeability heterogeneity introduced by faults can substantially impact groundwater flow. However, because faults are often poorly exposed at the surface, the architecture of the fault is frequently ...

Silica (SiO₂) concentration of water increases with contact time between the water and subsurface silica-bearing minerals. SiO₂ can thus be used as a natural tracer to investigate the different water ...

Groundwater is a key resource for water users in California’s Central Valley, a major agricultural hub with an economic output of tens of billions of dollars annually. Surface deformation in the ...

BUFFALO, N.Y. -- When engineers conduct research on groundwater, the water that flows beneath Earth's surface, they usually think of "large-scale" as one watershed -- an area of land where all of the ...

Groundwater is the largest source of freshwater, one of the world's most precious natural resources and vital for crops and drinking water. It is found under our very feet in the cracks and pores in ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

In the western US, water scarcity is a pressing issue, and striking a balance between providing flow when it is needed to support migratory fish habitats, like salmon and steelhead. Simultaneously ...

I’m not a geologist. I’m an astronomer, and a general science enthusiast, with an extra dollop of enthusiasm set in reserve for geology. It’s one of the reasons I’m so enthralled with asteroid impacts ...
