Department of Geography: Faculty Publications

The purpose of this study was to measure the spatial and temporal dimensions of drought occurrence in Nebraska. Such interpretations were facilitated by the computer generation of 468 maps showing monthly values of drought in Nebraska, from 1931 through 1969. While it was found that the frequency of consecutive drought is least in the central portion of the state, the intensity of drought is greatest in this region. Maps of correspondence which relate the areal correlation between rural population density and precipitation also indicate high positive relationships for central Nebraska.
