dc.description.abstractThe movement of saltwater in soils through capillary rise poses a concern, given its potential to affect both soil structure and hydraulic properties. This emphasizes the critical necessity of real-time monitoring to accurately measure and assess the salt concentration in the soil. Time-Domain Reflectometry (TDR) can be used to simultaneously measure the volumetric water content and bulk electrical conductivity of soil over time. Bulk electrical conductivity serves as a valuable metric for estimating pore water electrical conductivity, providing a basis for establishing a correlation with the salt concentration in the soil. Capillary rise experiments, instrumented with TDR probes, were conducted to measure the volumetric water content and bulk electrical conductivity of two distinct sand grades (30/40 and 40/50). These experiments encompassed a series of trials involving varying concentrations of salt solutions, juxtaposed with a control test utilizing deionized water. Further batch testing was conducted using the same sands to establish empirical relationships between bulk electrical conductivity and soil pore water concentration. The time series data, encompassing experimental volumetric water content and concentration from the capillary rise experiment, was used for inverse modelling to estimate soil hydraulic and solute transport properties. The findings from this study indicate that TDR provides accurate results for water content and electrical conductivity in column capillary rise experiments. The results also suggest that TDR observation data coupled with inverse modelling provides a soil water characteristic curve comparable to that measured using an evaporation method with the use of HYPROP. The outcomes of this study offer valuable insights into comprehending the intricate dynamics of water and salt within soil systems.
