Estimation of flow velocities and salt movements in unsaturated zone using isotopic and conventional techniques.
Sci. Total Environ. 138, 235-247 (1993)
Isotopic and conventional techniques were used to estimate the moisture flow velocities and movement of salts in the unsaturated zone. The experiments were performed using normal delta of irrigation and prolonged irrigation of the fields. The results of the study show that the flow velocities due to normal irrigation practice, determined through both techniques are in good agreement. In the case of prolonged irrigation, flow velocities are many times higher and decrease up to a depth and then become constant. In loamy soils, the salts keep moving up and down in the upper soil layers while in sandy soils they are leached to the water table.
