Bohling, Geoffrey C. / A ground penetrating radar study of water table elevation in a portion of Wisconsin's central sand plain
I. Introduction: motivation and objectives, pp. 1-9 PDF (2.5 MB)
Water table maps can be used to help delineate the distribution of recharge and discharge in a region. In this study, water table maps pro- duced from the GPR surveys were used as input to a mass balance model which calculates a recharge/discharge distribution based on the configuration of the water table. Although these modeling efforts were not very successful, it is possible that a different modeling technique would yield more reasonable results. If so, GPR would be a useful tool for recon- naissance studies of both water table configuration and groundwater recharge/discharge. The recharge modeling results are analyzed in Appen- dix 1. Chapter II is a discussion of the geology and hydrogeology of the study area. In Chapter III, relevant aspects of radar theory are presented. The field work for this study is described in Chapter IV. C. Location of Field Area A detailed map of the field area is shown in Figure 2. The field area is just southwest of the town of Plover in Portage County. The northern boundary of the study area is the bluff along the Wisconsin River and its adjoining wetlands. A groundwater divide runs through the study area. North of this divide, groundwater flows toward the Wisconsin River. The area south of this divide is part of the Buena Vista Groundwater Basin, studied by Stoertz (1985) and Faustini (1985).
