We present a closed solution for advective transport, and apply it to two typical real-world scenarios: i) a finite depthdistributed (i.e. Heaviside-type), and ii) an instantaneous top-surface broadcasted (i.e. Dirac-type) saline pulse. Our analytical solution is then incorporated into a stochastic stream tube model to compute the mean salinity profile in a heterogeneous field. An unusual phenomenon of plume contraction is observed when the soil is getting drier and drier (typically at long times during a water redistribution period). It is emphasized that our results are in agreement with previous analytical studies (see e.g. [22,23,24]), and match quite well synthetic as well as real data provided that sandy soils are dealt with.}, number={4}, journal={Journal of Agricultural Engineering}, author={Sommella, Angelo and Santini, Alessandro and Severino, Gerardo and Comegna, Alessandro}, year={2007}, month={Dec.}, pages={21–24} }
