Technical Note:Comparing and ranking soil drought indices performance over Europe,through remote-sensing of vegetation
Technical Note soil drought indices performance remote-sensing vegetation
2010/2/20
In the past years there have been many attempts to produce and improve global soil-moisture datasets and drought indices. However, comparing and validating these various datasets is not straightforwar...

A NOTE ON SINGLE AND MULTI-SITE OPERATIONAL HYDROLOGY
SINGLE MULTI-SITE OPERATIONAL HYDROLOGY
2009/10/29
Matalas' Residual Method as given in our paper, McMahon, Codner & Philips
(1972), contains an inconsistency. Initially we compute the non-seasonal spatial
correlations; this implicitly standardizes ...
A number of variables of interest in precipitation studies can be interpreted as
sums of random numbers of random variables, where the summed quantity is
a power transformation of raindrop diameter....
Technical Note：Updating procedure for flood forecasting with conceptual HBV-type models
flood forecasting conceptual HBV-type models rainfall-runoff model
2009/5/15
Flood forecasting is of increasing importance as it comes to an increasing variability in global and local climates. But rainfall-runoff models are far from being perfect. In order to achieve a better...
Technical Note：Determination of the SCS initial abstraction ratio in an experimental watershed in Greece
watershed Greece abstraction ratio
2009/5/13
The present study was conducted in an experimental watershed in Attica, Greece, using observed rainfall/runoff events. The objective of the study was the determination of the initial abstraction ratio...
For spatially explicit hydrological modelling an algorithm was required that works as a cellular automata on irregular meshes. From literature it was found that the usual algorithms applied for this p...
Technical Note：Seasonality in alpine water resources management–a regional assessment
snow-making water resources management
2009/4/28
Alpine regions are particularly affected by seasonal variations in water demand and water availability. Especially the winter period is critical from an operational point of view, as being characteris...
The construction of confidence intervals for frequency analysis using resampling techniques: a supplementary note
Bootstrap Jack-knife frequency analysis maximum likelihood method maximum product of spacings method
2009/3/11
In a recent contribution, Hall et al. (2004) examined the use of the Bootstrap resampling technique as a means of constructing confidence limits for the quantiles of the (two-parameter) Gumbel and the...
TECHNICAL NOTE: The representation of rainfall drop-size distribution and kinetic energy
drop-size distribution drop kinetic energy soil erosion
2009/3/11
To relate observed rainfall rates (R) to the kinetic energy flux (E) that affects soil erosion it is necessary to develop relationships between the two. This paper explores theoretical E–R relationshi...
