dc.description.abstract This paper describes how water content reflectometers (WCRs ) were analyzed to develop a calibration equation . Time domain reflectometry (TDR ) technique is the most prevalent method in in -situ moisture monitoring ; and WCR is a type of low frequency TDR sensors , which is sensitive to soil type . Developing soil -specific calibration and investigating different environmental effects on WCR calibration is important . This study focused on investigation of the soil dry density and temperature effects on WCR calibration in RMA soil . Two series of tests to develop soil -specific calibration with dry density and temperature offset were conducted . Results from testing program showed that WCR response was positive related to volumetric water content , dry density , and temperature . Equations were developed to illustrate the response -density -temperature -moisture relation . Application to a field site was also presented to illustrate the difference in volumetric water contents obtained by using manufacturer method and the calibration procedure drawn in this paper . en_US
