Hidrolik tasarım süreci ve tarımsal sulama yönetiminde evapotranspirasyonun tahmini oldukça önemlidir. Bu çalışmada günlük evapotranspirasyon miktarı için ortalama sıcaklık (S), bağıl nem (N), rüzgâr hızı (R), solar radyasyon (SR) parametreleri kullanılmıştır. Penman-Monteith, FAO (Food and Agriculture Organization) tarafından önerilen standart bir metottur. metoda göre yapılmış (ET0), referans...

The evapotranspiration rate has a vital role in agricultural water management. In this paper, ability of Box-Jenkins models in forecasting the reference potential evapotranspiration is estimated. For this purpose meteorological data of Mehrabad synoptic station in Tehran was selected. Using this data and according to eight famous evapotranspiration equations amounts of evapotranspiration were f...

The potential of modeling the FAO Penman-Monteith (FAO-56 PM) method for computing reference crop evapotranspiration (ETo) using feed-forward backpropagation artificial neural networks (FFBANN) with minimal measured climate data such as with the air temperature (maximum and minimum) was investigated using local climatic data from the Wa Meteorological weather station. Three FFBANN models were d...

abstract potential evapotranspiration is one of basic parameter in hydrologic cycle that should be estimate in irrigation design and scheduling, watershed hydrology studies. many applications in diverse disciplines require estimates of evapotranspiration (et) at hourly or smaller time steps. the primary objectives of this study were to compare the american society of civil engineers (asce) and ...

Estimation of evapotranspiration is imperative for effective forest, irrigation and water resources management as well to increase yields better crop management. This study aims evaluate the effectiveness Surface Energy Balance Algorithm Land (SEBAL) in estimating actual 15 years wheat 2A distributary Mahanadi canal Command which situated Dhamtari district Chhattisgarh state India. The Landsat ...
