Spatially Resolved Information on Karst Conduit Flow from In-cave ...

By: N. Goldscheider; U. Lauber; W. Ufrecht

Description: Institute of Applied Geosciences, Division of Hydrogeology, Karlsruhe Institute of Technology (KIT), Kaiserstr. 12, 76131 Karlsruhe, Germany. Artificial tracers are powerful tools for investigating karst systems. Tracers are commonly injected into sinking streams or dolines, while springs serve as monitoring sites. The obtained flow and transport parameters represent mixed information from the vadose, epiphreatic and phreatic zones (that is, the aquifer ...

Characterization of Groundwater Dynamics in Landslides in Varved C...

By: M. Bakker; T. A. Bogaard; J. E. Van Der Spek

Description: Water resources Section, Delft University of Technology, Delft, The Netherlands. Groundwater dynamics may play a significant role in landslides. A detailed model is developed of the groundwater dynamics in landslides in varved clays in the Trièves area in the French Alps. The varved clays consist of a sequence of alternating silt and clay layers, covered by a colluvium layer and cut through by fissures. The hydraulic conductivity of the clay layers is n...

By: O. Thual; C. Bouvier; E. Harader; S. Ricci; M. Coustau; V. Borrell Estupina; A. Piacentini

Description: URA CERFACS-CNRS, URA1875, Toulouse, France. The present study explores the application of a data assimilation (DA) procedure to correct the radar rainfall inputs of an event-based, distributed, parsimonious hydrological model. A simplified Kalman filter algorithm was built on top of a rainfall-runoff model in order to assimilate discharge observations at the catchment outlet. The study site is the 114 km2 Lez Catchment near Montpellier, France...

Estimating Evaporation from a Wet Grassland : Volume 11, Issue 1 (...

By: C. T. Agnew; M. C. Acreman; D. L. Gasca-tucker; J. R. Thompson

Description: Wet grasslands are being restored across the UK and Europe to reinstate their high biodiversity following over 50 years of drainage and conversion to arable agriculture. The water balance of many wet grasslands is dominated by precipitation and evaporation and it is essential to quantify evaporation rates to understand the hydrological functioning of wetlands and the implications for water resources in catchments where wetlands are being restored. This paper...

By: L. Delobbe; N. E. C. Verhoest; M. J. Van Den Berg

Description: Laboratory of Hydrology and Water Management, Ghent University, Coupure links 653, 9000 Ghent, Belgium. Fine scale rainfall observations for modeling exercises are often not available, but rather coarser data derived from a variety of sources are used. Effectively using these data sources in models often requires the probability distribution of the data at the applicable scale. Although numerous models for scaling distributions exist, these are oft...

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: Institute of Water and Environment, Cranfield University, Silsoe, Bedford, MK45 4DT, UK. During the autumn of 2000, England and Wales experienced the wettest conditions for over 270 years, causing significant flooding. The exceptional combination of a wet spring and autumn provided the potential for soil structural degradation. Soils prone to structural degradation under five common lowland cropping systems (autumn-sown crops, late-ha...

Since the Water Framework Directive (WFD) was passed in year 2000, the protection of water bodies in the EU must be understood in a completely different way. Regarding to combined sewer overflows (CSOs) from urban drainage networks, the WFD implies that CSOs cannot be accepted because of their intrinsic features, but must be...

Description: Department of Geosciences and Natural Resource Management, Copenhagen University, Copenhagen, Denmark. Uncertainty of groundwater model predictions has in the past mostly been related to uncertainty in the hydraulic parameters whereas uncertainty in the geological structure has not been considered to the same extent. Recent developments in theoretical methods for quantifying geological uncertainty have made it possible to consider this fa...

Description: CSIRO Land and Water, Graham Road, Highett, Victoria, Australia. Hydrological post-processors refer here to statistical models that are applied to hydrological model predictions to further reduce prediction errors and to quantify remaining uncertainty. For streamflow predictions, post-processors are generally applied to daily or sub-daily time scales. For many applications such as seasonal streamflow forecasting and water resources assessment, monthl...

Description: Max-Planck-Institut für Meteorologie, Germany. In this study we present the development of the dynamical wetland extent scheme (DWES) and its validation against present day wetland observations. The DWES is a simple, global scale hydrological scheme that solves the water balance of wetlands and estimates their extent dynamically. The extent depends on the balance of water flows in the wetlands and the slope distribution within the grid cells. In contras...

Regional Climate Models (RCMs) are valuable tools to evaluate impacts of climate change (CC) at regional scale. However, as the size of the area of interest decreases, the ability of a RCM to simulate extreme precipitation events decreases due to the spatial resolution. Thus, it is difficult to...
