Knowing crop water uptake each day is useful for developing irrigation scheduling. Many technologies have been used to estimate daily use. Sap flow one of the that measure through stem a plant and uptake. sensor an effective direct method measuring use, but it relatively expensive requires frequent maintenance. Therefore, alternative methods, such as evapotranspiration based on FAO 56 Penman-Mo...

16 Solar radiation is an important climatic variable for assessing reference evapotranspiration 17 (E0), but it is seldom available in weather station records. Meteosat satellite images processed 18 with the Heliosat-2 method provide the HelioClim-1 database, which displays spatialized 19 solar radiation data at a daily time step for Europe and Africa. The aim of the present work 20 was to inve...

This paper aims to estimate Actual Evapotranspiration of major crops by using CROPWAT 8.0 software in 2A canal command Mahanadi Dhamtari district. evapotranspiration is a key process hydrological cycle and sole term that links land surface water balance energy balance. Irrigation an essential part different because rainfall not enough for irrigated farmland. Long daily meteorological data inclu...

cultura (ETc), que pode ser determinada pelo coeficiente de cultivo (Kc) e pela evapotranspiração referência (ETo). Desse modo, o presente trabalho teve como objetivo determinar a ETc, Kc eficiência no uso água (EUA) variedades uva viníferas (Vitis vinifera), Agreste Pernambucano. Foram estudadas três uvas quais sejam: Cabernet Sauvignon, Malbec Muscat Petit Grain. A ETc foi método do balanço h...

comparison of linear and nonlinear (bilinear) time series models in reference crop evapotranspiration prediction in urmia synoptic stationreference crop evapotranspiration (eto) prediction is one of the important elements in optimizing agricultural water consumption. in this regard, one of the prediction approaches is to use the stochastic time series methods. in this research, ar (p) and arma(...

In geological remote sensing approaches for estimating evapotranspiration, METRIC method is among the most modern and precise that many positive experiments have been reported regarding its applicability. this study, value of actual evapotranspiration (ET) occurred in Marvdasht farmlands, Fars province, Iran, was calculated instantaneously (hourly) daily (24 hours), at 24 April 2017 using Lansa...
