HiResAlp - An innovative framework for the integration of multi-source data to determine soil moisture and evapotranspiration at high resolution in Alpine regions Project description Project description

Financing:  Autonomous Province of Bolzano
Period: 2013–2015
Contact: Giacomo Bertoldi


Soil moisture content (SMC) and evapotranspiration (ET) are key biophysical variables for a clear and complete understanding of water and carbon dynamics of terrestrial ecosystems.
The knowledge on spatial and temporal distribution of SMC and ET is fundamental in both hydrological applications, such as flood predictions, water reserve management, plant stress monitoring and precision farming, and earth sciences, like carbon fluxes estimation, meteorology and climate change assessment. 


The research project HiResAlp aims at defining an innovative framework where satellite EO imagery, in-situ measurements and modeling predictions will be exploited in a synergic way for mapping soil moisture and ET in Alpine areas.
The project will define how complementary products derived from different sources (last generation satellite imagery, in-situ measurement network and hydrological model predictions) can be exploited in a synergic way for deriving an optimal integrated product for mountain areas.
This product will be useful for early warning and water resources monitoring.
Major test site will be the grassland area of the Vinschgau/Venosta Valley in South Tyrol.
