IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
It is well known that vegetation plays a key role in catchment¡¯s water balance particularly in semi-arid areas that are
generally water-controlled ecosystems. Nowadays, many of the available dynamic vegetation models are quite complex
and they have high parametrical requirements. However, in operational applications the available information is quite
limited. Therefore parsimonious models together with available satellite information can be valuable tools to predict
vegetation dynamics. But, is a parsimonious model capable to reproduce properly the vegetation dynamics or, contrarily,
a more complex model is needed? And, can we really use only satellite data to implement a dynamic vegetation model?
In this work, we focus on a parsimonious dynamic vegetation model, using satellite information to implement it and we
compare it with a well-known physically based model using field data to implement it. The results suggest that the
proposed parsimonious model is able to adequately reproduce the dynamics of vegetation as well as the soil moisture
variations. In other words, it has been shown that a parsimonious model with simple equations can achieve good results
in general terms and it is possible to assimilate satellite for the model implementation.
