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...
The evaporation losses are very high in warm-arid regions and their accurate evaluation is vital for the sustainable management of water resources. assessment such involves extremely difficult original tasks because scarcity data countries with an arid climate. main objective this paper to develop models simulation pan-evaporation help Penman Hamon’s equations, Artificial Neural Networks (ANNs)...
Accurate estimation of latent heat flux (LE) is critical in characterizing semiarid ecosystems. Many LE algorithms have been developed during the past few decades. However, the algorithms have not been directly compared, particularly over global semiarid ecosystems. In this paper, we evaluated the performance of five LE models over semiarid ecosystems such as grassland, shrub, and savanna using...
Accurate estimation of the satellite-based global terrestrial latent heat flux (LE) at high spatial and temporal scales remains a major challenge. In this study, we introduce a Bayesian model averaging (BMA) method to improve satellite-based global terrestrial LE estimation by merging five process-based algorithms. These are the Moderate Resolution Imaging Spectroradiometer (MODIS) LE product a...
Accurate estimation of evapotranspiration (ET) is vital for water resource development, planning and management, particularly in the present global warming context. A large number empirical ET models have been developed estimating ET. The main limitations this method are that it requires several meteorological variables an extensive data span to comprehend pattern accurately, which not availabl...
