Longitudinal dispersivity determination using conservative tracer in the field

Solute transport parameters determination in the unsaturated zone is of great importance for groundwater pollution risk assessment. The subject of this study was Fluvisol developed on the floodplain of Sava River. The goal of the study was estimation of longitudinal dispersivity which is one of the main solute transport parameters. Field experiment using conservative tracer calcium chloride was carried out. Investigated site is situated about eight hundred meters from right bank of Sava River at Kosnica regional well field. Longitudinal dispersivity was estimated by inverse modeling chloride concentration using HYDRUS 1D. Due to collapse of pedological pit during application of tracer and sampling of percolating solution, field experiment was not completed. Therefore, estimation of longitudinal dispersivity was performed on incomplete data set.
