Performance of the Minievaporimeter UFV-1 to estimate the reference evapotranspiration in relation to the constant groundwater Table lysimeter

In this work the aim was to evaluate the performance of the minievaporimeter UFV-1, operating with water at a 30 mm border level, to estimate (ET0) in relation to the lysimeter with constant groundwater table. The minievaporimeter UFV-1 is made of PVC and consists of a tube with internal diameter of...
