Model study on the transport and accumulation of salt near an irrigation canel

Water development projects induce changes in the water regime of the adjacent area, in particular, the water table in the vicinity of the project. This in its turn, induces changes in soil water regime and also influences the soil salinization. An experiment depicting an unsaturated zone adjacent to an irrigation canal of known water quality have been performed. A 2-dimensional numerical model based on FDM and with MOC for the solute distribution has been developed for simulation of the said process. The results are compared with the observations from the experiment.
