A simple global Budyko model to partition evaporation into interception and transpiration

Evaporation is a very important flux in the hydrological cycle and links the water and energy balance of a catchment. The Budyko framework is often used to provide a first order estimate of evaporation, since it is a simple model where only rainfall and potential evaporation is required as input. Many researchers have tried to improve the Budyko...

Using remote sensed actual evaporation to improve hydrological models

In hydrological models evaporation is often still quite uncertain. Potential evaporation is used as input, but the modelling of plant stresses is not always accurate enough to describe the behaviour in reality. In situ measured actual evaporation data is rare, and doing measurements is time consuming and expensive. With the advance of satellite...

Evaporation in conceptual rainfall-runoff models: Testing model realism using remotely sensed evaporation

The procedure to determine evaporation in hydrological models is considered to be unsatisfactory by some researchers; ‘too’ accurate by others. In this procedure catchment scale evaporation is related to some form of potential evaporation, determined with point scale meteorological data. The main criticism is that the potential evaporation is...
