| Zusammenfassung |
| In the last years satellite remote sensing applications in hydrology have
considerably progressed. A new multi-temporal satellite data-analysis
approach has been recently suggested in order to estimate space-time changes
of geophysical parameters possibly related to the increase of environmental
and hydro-geological hazards. Such an approach has been already used both
for flooded area mapping (using AVHRR data) and for soil wetness index
estimation (using AMSU data).
In this work, a preliminary sensitivity analysis of the proposed Soil
Wetness Variation Index (SWVI) is made in the case of low intensity
meteorological events by the comparison with hydrological (precipitation)
data. This analysis, as a first step of a more complex work in progress, is
targeted to a first evaluation of the reliability of the SWVI in describing
soil response to precipitations of different duration and intensity. |
