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 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 ...

Ecology and Society, Vol. 12, No. 2 (Dec 2007) (19 pages) ABSTRACT. We couple two spatial-temporal models, a backcast land-use change model and a groundwater flow model, to develop what we call ...

In a new study, researchers applied a large-scale model linking surface water to groundwater, which can be used for estimating water resources at a high spatial resolution. Against the backdrop of ...

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 ...

Humankind’s collective thirst is slowly desiccating landscapes worldwide, a study of groundwater finds. Water stored in aquifers underground makes up the vast majority of accessible freshwater on ...
