Abstract

A major step in the design and evaluation of FURROW IRRIGATION system is the determination of INFILTRATION function. The purpose of this study is to compare, INFILTRATION measurement results using double ring and INFLOW-OUTFLOW METHOD following consecutive irrigation events. Study of bulk density variation after each irrigation was another aim of this investigation. Experiments were conducted on a site near agriculture faculty of Shahid Chamran University. Results indicate that correlation coefficient in the first irrigation period is low in comparison with the others periods. Cumulative INFILTRATION is reduced in the second irrigation in comparison with the first irrigation 180 minutes after irrigation started. Also cumulative INFILTRATION is reduced in the third irrigation in comparison with the second irrigation. During the fourth irrigation, cumulative INFILTRATION increased in comparison with the third irrigation which was due to the weed growth in thefurrows. Results show that calculated INFILTRATION rate using INFLOW-OUTFLOW METHOD is 4.4 times greater than double ring method. The results also show that for short time periods (less that 180 minutes), Kostiakov method is in a better agreement with Kostiakov-lewis method. Cumulative INFILTRATION was shown to be higher using Kostiakov-lewis method in comparison to actual measurement for long time periods (more than 180 minutes).
