SUMMARY

The present paper reports studies made on noil-vegetated canals of different slopes. The referred tests also included investigations on the late effects of a solution which was sprinkled on lhe canal walls and bottom by means of a garden watering can aimed at making them impervious.

The data obtained showed that for slopes ranging from 1 to 10% the amount of water infiltrated is high, and soil loss is low. Eor 20% slope canals the soil loss is high and the volume of water infiltrated is tow. The data show too that for the particular type of soil used, the treatment with the 3% solution of sodium hydroxide increased the amount of water infiltrated in the different canals and reduced in 55% the soil loss for all slopes tested.
