Abstract
Over past decades, extensive research has been performed on the measurement of land subsidence as a result of compaction of aquifer. This paper describes results from a new field-monitoring system to evaluate changes in matric suction and temperature profiles in soil layers over an extended time period. The monitoring system used in this study consists of inserting dielectric sensors into a 105 m borehole, drilled in a site in Ardabil Plain, The monitoring results from the site were used to calibrate predictions from HYDRUS-1D. The physical and hydraulic properties of the soil materials in different layers were obtained through performing some soil characteristics and filter paper tests performed on soil samples. The calibrated model was then used to predict the moisture and suction profiles of the soil layers over the next 10 years. Results of this study are believed to estimate the location of the water ground and understand effects that groundwater overdraft or weather conditions may have on soil’s deformation behavior.
