AbstractA topographic three dimensional scanner is similar to a radiometric total station, but it does not require a reflecting prism and the optical measurement device is motorized and automated. With this device, very large survey data sets can be collected with moderate effort. In this paper, the application of a 3D scanner to surface and sprinkler irrigation research is presented and discussed. In surface irrigation, the scanner was successfully applied to: 1) the survey of soil surface elevation, including furrowed areas; 2) the determination of flow cross sections; 3) surveying the location of the advancing front; and 4) measuring water surface elevation. The device showed some limitations in the measurement range, which was limited to about 35 m for water surface elevation and 50 m for the detail survey of furrowed areas. In sprinkler irrigation, the scanner was applied to the survey of the sprinkler jet and the irrigation drops during their trajectory. The scanner seemed to fail to survey fine drops, since falling drops were rarely scanned in the vicinity of the sprinkler. Despite the reported limitations, the 3D scanner seems to be destined to occupy a relevant place in the irrigation research laboratory.
