Variability of Extragalactic Objects in Relation to Redshift, Color, Radio Spectral Index and Absorption Lines
Galaxies active galaxies quasars
2009/5/20
Optical variability of extragalactic objects, viz., QSOs, BL Lacs and Seyfert galaxies has been monitored systematically over an appreciable period of time and a large amount of data have accumulated....
Hydrological response to different time scales of climatological drought：an evaluation of the Standardized Precipitation Index in a mountainous Mediterranean basin
Standardized Precipitation Index drought conditions
2009/5/18
At present, the Standardized Precipitation Index (SPI) is the most widely used drought index to provide good estimations about the intensity, magnitude and spatial extent of droughts. The main advanta...
On the calculation of the topographic wetness index：evaluation of different methods based on field observations
topographic wetness index field observations
2009/5/13
The topographic wetness index (TWI, ln(a/tanβ)), which combines local upslope contributing area and slope, is commonly used to quantify topographic control on hydrological processes. Methods of comput...
Towards a hydrological classification of European soils：preliminary test of its predictive power for the base flow index using river discharge data
European soils base flow hydrological classification
2009/5/12
Predicting discharge in ungauged catchments or contaminant movement through soil requires knowledge of the distribution and spatial heterogeneity of hydrological soil properties.
Because hydrolog...
