Evapotranspiration (ET) is a significant parameter of hydrologic cycle.Accurate calculation tonic shower cap or estimation of ET is an important issue for water management engineers and irrigation engineers.However, it is not always so simple to calculate ET because of the direct and indirect effects.

In this study, Daily ET is calculated by using Penman FAO 56 standard equation which is developed by U.S.Food and Agricultural Organization-FAO.

1416 daily meteorological data is taken from USGS (United States of Geological Survey) South Carolina observation station.Data set is divided as training and test set randomly and test set is existed from 233 daily data.Daily Air Temperature, Wind Speed, Relative Humidity and Solar Radiation meteorological variables are used in adaptive neuro fuzzy inference operation igloo white system (ANFIS) model creation process.

Three different models are created and results are compared with each other.
