Hydrologic Similarity Among Catchments Under Variable Flow Conditi...

By: M. Stieglitz; S. Patil

Description: School of Civil and Environmental Engineering, Georgia Institute of Technology, Atlanta, GA, USA. An assessment of regional similarity in catchment stream response is often needed for accurate predictions in ungauged catchments. However, it is not clear whether similarity among catchments is preserved at all flow conditions. We address this question through the analysis of flow duration curves for 25 gauged catchments located across four river basins in ...

Multivariate Design Via Copulas : Volume 8, Issue 3 (10/06/2011)

By: F. Durante; C. De Michele; G. Salvadori

Description: Dipartimento di Matematica, Università del Salento, Provinciale Lecce-Arnesano, P.O. Box 193, 73100 Lecce, Italy. Calculating return periods and design quantiles in a multivariate framework is a difficult problem: essentially, this is due to the lack of a natural total order in multi-dimensional Euclidean spaces. This paper tries to make the issue clear. First, we outline a possible way to introduce a coherent notion of multivariate total ord...

Description: Institute for Environment and Sustainability, Joint Research Center of the European Commission, Via Enrico Fermi 2749, 21027 Ispra (VA), Italy. In Europe, public water withdrawals make up on average 30% and in some cases up to 60% of total water withdrawals. These withdrawals are becoming increasingly important with growing population density; hence there is a need to understand the spatial and temporal trends involved. Pan-European public/municipal wate...

Description: Physical and Regional Geography Research Group, Katholieke Universiteit Leuven, Celestijnenlaan 200E, 3001 Heverlee, Belgium. Restoration of degraded land in the Southern Ecuadorian Andes has led to alterations in the functioning of degraded catchments. Recovery of vegetation on areas affected by overgrazing, as well as the reforestation or afforestation of gully areas have given rise to modifications of hydrological connectivity within the catchments.

Description: Swiss Federal Institute of Aquatic Science and Technology (Eawag), Dübendorf, Switzerland. Spatially distributed hydrological models are popular tools in hydrology and they are 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.

Description: Physical Geography and Quaternary Geology, Stockholm University, Sweden. Permafrost thawing is likely to change the flow pathways taken by water as it moves through arctic and sub-arctic landscapes. The location and distribution of these pathways directly influence the carbon and other biogeochemical cycling in northern latitude catchments. While permafrost thawing due to climate change has been observed in the arctic and sub-arctic, direct observations...
