Models used for the remote estimation of evapotranspiration are evaluated using aircraft observations over two distinct vegetation regimes in southwestern Australia. Single-source models using an empirically determined excess resistance term performed better than a two-source model, which does not require such a parameterization. The mean absolute difference between measured and estimated value...

Modeling potential evapotranspiration (ET0) is an important issue for water resources planning and management projects involving droughts flood hazards. Evapotranspiration, one of the main components hydrological cycle, highly effective in drought monitoring. This study investigates efficiency two machine-learning methods, random vector functional link (RVFL) relevance machine (RVM), improved w...
