Abstract

Gholam-gardeshy FURROW IRRIGATION is a modified form of FURROW IRRIGATION, mainly used in Iran. However, to date no research has been noted about the hydraulic performance of this method of irrigation. The use of this method of irrigation, especially in heavy soils and steep slopes, can reduce tail water runoff as well as increase application efficiency as compared to the FURROW IRRIGATION. To evaluate the performance of this method of irrigation and to compare the results with a FURROW IRRIGATION, in three experimental fields, (Khazaneh with sandy clay loam soil texture and 0.3%, I% and 2% soil slopes, University with sandy clay loam soil texture and 0.29"10soil slope and finally Roodasht with clay soil texture and 0.1% soil slope), ordinary and Gholam-gardeshy design of were designed and equipments including constant head water delivery system to the furrows were installed in any of the experimental fields. To determine the parameters of Kostiakov-Lewis INFILTRATION equation, volume balance method was employed. The results showed that for the same irrigation time and inflow discharge the velocity of advance and tail water runoff was less for Gholam-gardeshy FURROW IRRIGATION as compared to the FURROW IRRIGATION. In the three experimental fields, for Gholam-gardeshy FURROW IRRIGATION, INFILTRATION was more as compared with the FURROW IRRIGATION and as the slope of the field increases the differences between the two methods decrease. Both methods had nearly the same furrow cross section in the three experimental fields. In the three experimental fields, as the net depth of irrigation increased the application efficiency increased for either method. In both irrigation methods the determined advance equations were able to predict the measured data with a coefficient of determination of more than 90 percent. The difference between the two methods for longitudinal advance and infiltrated water along the field was significant at 5 percent level.
