EFFICIENT AGRICULTURE WATER USE IS OF CRUCIAL IMPORTANCE FOR WATER RESOURCES MANAGEMENT. CONSEQUENTLY, ACCURATELY DETERMINING EVAPOTRANSPIRATION (ET) IS THE FIRST STEP FOR IMPROVING IRRIGATION EFFICIENCY AND PRODUCTIVITY AND FOR QUANTIFYING THE ECOSYSTEM WATER BALANCE. SEVERAL APPROACHES FOR DETERMINING ET HAVE BEEN PROPOSED IN LITERATURE, BUT THE RELATION BETWEEN HIGH AND LOW SPATIAL RESOLUTION METHODS STILL REMAINS UNRESOLVED IN IRRIGATION STUDIES AND WATER MANAGEMENT PLANNING.
