A NEW TOOL FOR HILLSLOPE HYDROLOGISTS : SPATIALLY DISTRIBUTED GROUNDWATER LEVEL AND SOILWATER CONTENT MEASURED USING ELECTROMAGNETIC INDUCTION

New methods for obtaining and quantifying spatially distributed subsurface moisture. Linear regression analysis to compared terrain electrical conductivity measurement derived from multiple electromagnetic induction frequencies to a distributed grid of water table depth and soil-moisture measurement. Results suggest that the method may be promissing for a large number of distributed soilwater and groundwater depth measurements with a reasonable degree of accuracy.
