By: A. Koukouvinos; E. Rozos; I. Nalbantis; A. Efstratiadis; D. Koutsoyiannis

Description: Department of Water Resources and Environment, School of Civil Engineering, National Technical University of Athens, Greece. The HYDROGEIOS modelling framework represents the main processes of the hydrological cycle in heavily disturbed catchments, with decision-depended abstractions and interactions between surface and groundwater flows. A semi-distributed approach and a monthly simulation time step are adopted, which are sufficient for water resources ...

By: D. Gillieson; M. Leblanc; D. O'Grady

Description: School of Earth and Environmental Sciences, James Cook University, 14–88 McGregor Road, Smithfield, QLD 4878, Australia. Envisat ASAR Global Monitoring Mode (GM) data are used to produce maps of the extent of the flooding in Pakistan which are made available to the rapid response effort within 24 h of acquisition. The high temporal frequency and independence of the data from cloud-free skies makes GM data a viable tool for mapping flood water...

By: P. Weisskopf; U. Zihlmann; C. Stamm; M. Honti; T. Doppler

Description: Swiss Federal Institute of Aquatic Science and Technology (Eawag), Dübendorf, Switzerland. Spatially distributed models are popular tools in hydrology claimed to be useful to support management decisions. Despite the high spatial resolution of the computed variables, calibration and validation is often carried out only on discharge time series at specific locations due to the lack of spatially distributed reference data. Because of this restriction...

By: U. Wiesmann; H. Hurni; K. C. Abbaspour; B. Notter

Description: Department of Integrative Geography, University of Bern, Bern, Switzerland. Reconciling limited water availability with an increasing demand in a sustainable manner requires detailed knowledge on the benefits people obtain from water resources. A frequently advocated approach to deliver such information is the ecosystem services concept. This study quantifies water provision as an ecosystem service for the 43 000 km2 Pangani Basin in Tanzania...

By: F. Russo; L. Baldini; F. Napolitano; S. Sebastianelli

Description: Department of Hydraulic, Transportations and Roads, Sapienza Univ. of Rome, Rome, Italy. Rainfall intensity data in pixels very far from radar are less correlated than values in pixels near the radar, because at far distances the width of a range-bin is comparable or bigger than the pixel width, so in a pixel there are one or just a few rainfall intensity values. Vice versa, near the radar, there are many radar resolution bins which belong to a single pi...

Description: Department of Physical Geography, Utrecht University, Utrecht, The Netherlands. In climate models, lateral terrestrial water fluxes are usually neglected. We estimated the contribution of vertical and lateral groundwater fluxes to the land surface water budget at a subcontinental scale, by modeling convergence of groundwater and surfacewater fluxes. We present a hydrological model of the entire Danube Basin at 5 km resolution, and use it ...

By: H.-d. Yeh; C.-m. Chang

Description: Institute of Environmental Engineering, National Chiao Tung University, Hsinchu, Taiwan. Owing to the analogy between the solute and heat transport processes, it can be expected that the rate of growth of the spatial second moments of the heat flux in a heterogeneous aquifer over relatively large space scales is greater than that predicted by applying the classical heat transport model. The motivation of stochastic analysis of heat transport at the fiel...

Description: CSIRO Land and Water, Highett, Victoria, Australia.

Observations of antecedent streamflows or rainfall commonly used to represent the initial catchment conditions are surrogates for the true source of predictability and can potentially have limitations.
