Abstract

This project includes analyzing the problem of surface runoff water losses in the Koya University gardens. We started with selecting a flat rectangular area 7.5*10 m in the garden near the registration office that was irrigated by a sprinkler irrigation system. The dimension of the water collection unit was 1.25*1.25 m, with an operating system duration of 30 minutes. By measuring the depths of water in the cans and comparing with the volume of water output, we find the difference due to evaporation, spray losses and surface runoff, i.e. the total water output of the sprinkler divided into four parts infiltration, surface runoff, evaporation, spray for controlling surface runoff we measured soil infiltration and we find that the rate of net water reaching the soil surface is more than the basic infiltration rate. Keywords: evaluation irrigation, assessment, sprinkler irrigation, irrigation uniformity, irrigation efficiency.
