A zone of nitrogen-contaminated groundwater associated with a barnyard was studied to determine the quantity of inorganic nitrogen reaching the groundwater from the barnyard. From piezometric ...

A new computer algorithm that can "fill in" underground water levels in areas where quality data is not available could lead to improved models of groundwater flow in regions where pumping and aquifer ...

In their paper, Miguez-Macho and Fan propose a new definition of the aridity index, which they prefer to refer to as the "global humidity index," since the calculation better reflects humidity than ...

Powerful pulses of groundwater flow up from beneath Lakes Michigan and Huron, which together form one of the largest freshwater systems in the world. This groundwater flux may dramatically alter how ...
