The textbooks of soil science, discussing the effect of degree of slope on surface run-off and erosion, mention that the lowest amount of run-off occurs at (0) slope. As the degree of slope increases, the amount of surface run-off and erosion also increases. Different experiments report that an increase in the degree of slope is accompanied by an increase in surface run-off and erosion. However, in one experiment, Duley and Kelly (2) report that the degree of slope has only a slight effect on infiltration of water. Several experiments have been done on the effect of exchangeable sodium on the physical properties of soils. These experiments indicate that increase in the amount of exchangeable sodium caused a decrease in water permeability and thus water intake. The objective of the following experiments was to combine these two different variables in a study on run-off and erosion. An attempt has been made to find out the influence of slope on surface run-off, erosion, and infiltration of water in the soil, at three levels of exchangeable sodium, and at the same time to see if the results of former experiments can be verified.
