Current remote sensing satellites can provide valuable information
relevant to hydrological monitoring. And by using available in situ
measurements together with the satellite data the information can be
even more valuable.
The FloodFore project developed new methods to estimate hydrological
parameters from multi source remote sensing and in situ data. These
hydrological parameters are important input to the watershed simulation
model in order to improve the accuracy of its forecasts.
In the project several new methods were either developed or
demonstrated: satellite based snow water equivalent (SWE) estimation,
weather radar based accumulated precipitation estimation, satellite
based soil freezing state determination, and SWE estimation with high
spatial resolution using both microwave radiometer and SAR data. Also
a visualisation system for multi source information was developed to
demonstrate the new products to users.
The effect of the snow remote sensing estimates to the hydrological
forecasting accuracy was studied for the Kemijoki river basin.
The commercialisation possibilities of the results of the project were alsostudied.
