Description :
This study focused on Waukesha County, where urban development has been accelerating while groundwater has been declining over the last several decades. The AA. analyzed data about groundwater withdrawal, groundwater level, land use/land cover, and precipitation utilizing correlation analysis, geographically weighted regression, land use change analysis, and map overlay. Their findings show that : the extent of urban areas expanded faster in regions with high recharge potential than in those with low or moderate recharge potential; the correlation of urban growth with groundwater level is highly variable over time and space; and changes in groundwater level are strongly related to the spatial distribution of groundwater withdrawal. The study pinpointed the need to consider the spatial unevenness of groundwater withdrawal in understanding the changes in groundwater level and groundwater recharge potential for better management of groundwater resources.
