Streamflow data assimilation for soil moisture analysis
Streamflow data assimilation soil moisture analysis
font style='font-size:12px;'>
2010/2/5
Streamflow depends on the soil moisture of a river catchment and can be measured with relatively high accuracy. The soil moisture in the root zone influences the latent heat flux and, hence, the quant...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
font style='font-size:12px;'>
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...

real-time flood detection split-based automatic thresholding procedure TerraSAR-X data
font style='font-size:12px;'>
2009/12/16
In this paper, an automatic near-real time (NRT) flood detection approach is presented, which combines histogram thresholding and segmentation based classification, specifically oriented to the analys...
