Abstract

The proper maintenance of irrigation sub-units is a key aspect for efficient irrigation and for ensuring that the theoretical high drip irrigation application efficiencies are achieved. The performance assessment methods are based on the discharge measurements of some emitters sampled within the irrigation unit. The emitter selection is a key aspect for guaranteeing that plot heterogeneity is well represented. In this work, thermal images obtained by means of an Unmanned Aerial Vehicle over an irrigation district were used to determine irrigation performance. Four irrigation sub-units were assessed with standard methods. Canopy temperature showed a good correlation with the total flow discha..
