Towards a better representation of the subsurface across the continental US : developing hydraulic conductivity datasets for integrated hydrologic models
Altmetrics
Abstract
Groundwater is the largest source of accessible freshwater, accounts for over 30% of total water use worldwide, and is intrinsically connected to land-surface processes. Groundwater flow is largely influence by hydraulic gradients and the properties of the porous media, such as hydraulic conductivity. The methods by which hydraulic conductivity is measured vary greatly among local, regional, and global scale measurements. Local-scale measurements can be made through borehole tests, and large-scale conductivity values are regularly regarded as the geometric mean of local-scale measurements. ...
