Regional Climate Models Downscaling in the Alpine Area with Multim...

By: S. Barbarino; L. A. Renier; C. Ronchi; D. Cane

Description: Regional Agency for Environmental Protection – Arpa Piemonte, Torino, Italy. The climatic scenarios show a strong signal of warming in the Alpine area already for the mid XXI century. The climate simulations, however, even when obtained with Regional Climate Models (RCMs), are affected by strong errors where compared with observations, due to their difficulties in representing the complex orography of the Alps and limitations in their physical parametri...

By: F. Janod; J. L. Mattiuzzo; A. Revil; A. Jardani; A. Bolève

Description: CNRS-CEREGE, Université Paul Cézanne, Aix-en-Provence, France. The classical formulation of the coupled hydroelectrical flow in porous media is based on a linear formulation of two coupled constitutive equations for the electrical current density and the seepage velocity of the water phase and obeying Onsager's reciprocity. This formulation shows that the streaming current density is controlled by the gradient of the fluid pressure of the water phase an...

By: A. Jenkins; R. F. Wright; R. C. Ferrier; B. J. Cosby

Description: Department of Environmental Sciences, University of Virginia, Charlottesville, VA22901 USA. The MAGIC model of the responses of catchments to acidic deposition has been applied and tested extensively over a 15 year period at many sites and in many regions around the world. Overall, the model has proven to be robust, reliable and useful in a variety of scientific and managerial activities. Over the years, several refinements and additions to MAGIC have b...

Description: Chaire de recherche EDS en prévisions et actions hydrologiques, Département de génie civil et de génie des eaux, 1065, avenue de la Médecine, Québec, Qc, G1V 0A6 Canada. This work investigates the added value of ensembles constructed from seventeen lumped hydrological models against their simple average counterparts. It is thus hypothesized that there is more information provided by all the outputs of these models than by their single aggrega...

Description: Department of Civil Engineering, Federal University of Pernambuco, Recife, Brazil. Water availability for a range of human uses will increasingly be affected by climate change, especially in the arid and semiarid tropics. The main objective of this study is to evaluate the infrastructure sufficiency in meeting water demand under climate-induced socio-hydrological transition in the Capibaribe River basin (CRB). The basin has experienced spatial and secto...

Technical Note: Water Flow Routing on Irregular Meshes : Volume 3,...

By: D. Bänninger

Description: Institute of Environmental Geosciences, University of Basel, Bernoullistrasse 30, 4056 Basel. For spatial explicit hydrological modelling an algorithm was needed which works as cellular automata on irregular meshes. From literature it was found that usual algorithms applied for this purpose do not route the water flow correctly to its adjacent cells. In this study the hydraulic linking between mesh cells is done by calculating the flow cross section bet...

Description: Instituto Pirenaico de Ecología, CSIC (Spanish Research Council), Campus de Aula Dei, P.O. Box 202, Zaragoza, 50080, Spain. In this study we analyzed the influence of the North Atlantic Oscillation (NAO) on the streamflow in 187 sub-basins of the Iberian Peninsula. Monthly and one-month lagged correlations were conducted to assess the spatio-temporal extent of the NAO influence on Iberian river discharges. Analysis of the persistence of the winter NAO th...

Description: CRA – Research centre for Agrobiology and Pedology, Florence, Italy. The adoption of precision agriculture in viticulture could be greatly enhanced by the diffusion of straightforward and easy to be applied hydropedological models, able to predict the spatial variability of available soil water. The Lin's and Host hydropedological models were applied to standard soil series descriptions and hillslope position, to predict the distribution of hydrological...

By: W. E. Bardsley; V. V. Vetrova

Description: Department of Earth & Ocean Sciences, University of Waikato, Hamilton, New Zealand. Data-sparse zones in scatter plots of hydrological variables can be of interest in various contexts. For example, a well-defined data-sparse zone may indicate inhibition of one variable by another. It is of interest therefore to determine whether data-sparse regions in scatter plots are of sufficient extent to be beyond random chance. We consider the specific situation o...

Description: Department of Forest Rangeland and Watershed Stewardship, Colorado State University, Fort Collins, CO 80523-1472, USA. Interactions between road and stream networks are complex and are influenced by a range of environmental and road design characteristics. These interactions are not clearly understood and are the subjects of current research. To increase understanding of these interactions we explore the concepts of Road and Stream Network Connectivity (...

Description: Microbiology Laboratory, University of Neuchâtel, rue Emile Argand 9, 2007 Neuchatel, CH. Bacteriophages are increasingly used as tracers for quantitative analysis in both hydrology and hydrogeology. The biological particles are neither toxic nor pathogenic for other living organisms as they penetrate only a specific bacterial host. They have many advantages over classical fluorescent tracers and offer the additional possibility of multi-point injection ...

Description: Faculté des géosciences et de l'environnement, Université de Lausanne, Lausanne, Switzerland. This paper asks a simple question: if humans and their actions co-evolve with hydrological systems (Sivapalan and Blöschl, 2012), what is the role of those humans who are simultaneously hydrological scientists, bound up within this system? To put it more directly, can we, as socio-hydrologists study the socio-hydrological world in isolation from that world in ...

Description: Water Engineering and Management, Faculty of Engineering Technology, University of Twente, P.O. Box 217, 7500 AE Enschede, the Netherlands. The impacts of climate change on the seasonality of low flows are analysed for 134 sub-catchments covering the River Rhine basin upstream of the Dutch–German border. Three seasonality indices for low flows are estimated, namely seasonality ratio (SR), weighted mean occurrence day (WMOD) and weighted persistence (WP)....
