The design, development, and application of a hydroinformatic system for estimating evapotranspiration is presented. Reference evapotranspiration is calculated via the Penman-Monteith approach as well as the Class A pan evaporation records. Station- and grid-based methods for estimating reference evapotranspiration are developed and coupled to GIS technology. The station-based method provides the user with evapotranspiration estimates at point locations, corresponding to meteorological stations within the study area. The grid-based method is developed in order to provide an improved understanding of the spatial variation in evapotranspiration. A graphical interface provides model execution and functionality for use in the management phase of the analysis. The island of Crete is used as a case study to illustrate the applicability of the system.
