Hydrologic landscape regions of Nevada

Hydrologic landscape regions group areas according to their similarity in landscape and climate characteristics.
These characteristics represent variables assumed to affect hydrologic processes in the environment. Hydrologic
landscape regions in Nevada were delineated using geographic information system tools and statistical methods
including cluster analysis. The data layers of hydrogeology, precipitation, soil permeability, land surface slope
and aspect were used to identify the hydrologic landscape regions. Sixteen hydrologic landscape regions were
identified through cluster analysis. The hydrologic landscape regions are noncontiguous in nature and can range
from small areas which tend to be in the mountain ranges to very large areas in the basins.
