Description: DICAM Dipartimento di Ingegneria Civile, Chimica, Ambientale e dei Materiali ALMA MATER STUDIORUM Università di Bologna, Bologna, Italy. In the northern Apennines of Italy, springs are quite widespread over the slopes. Due to the outcropping of low-permeability geologic units, they are generally characterized by low-yield capacities and high discharge variability during the hydrologic year. In addition, low-flow periods (discharge lower than 1 Ls-1

By: C. La Spada; D. E. Walling; P. Porto; N. Mallimo

Description: Dipartimento di Agraria, Università degli Studi Mediterranea, Località Feo di Vito, Reggio Calabria, Italy. A long-term measurement programme was operated in southern Italy during the 1960s and 1970s, to provide information on the suspended sediment yields from the main river basins. Information obtained for the rivers of Calabria suggests that suspended sediment yields in this area are relatively low. However, there is evidence that the intensity of land de...

By: N. Schütze; J. Grundmann; Y. H. Subagadis

Description: Technische Universität Dresden, Institute of Hydrology and Meteorology, 01069 Dresden, Germany. The conventional methods used to solve multi-criteria multi-stakeholder problems are less strongly formulated, as they normally incorporate only homogeneous information at a time and suggest aggregating objectives of different decision-makers avoiding water–society interactions. In this contribution, Multi-Criteria Group Decision Analysis (MCGDA) using a fuzzy-sto...

By: P. R. Sarukkalige; V. T. V. Nguyen; H. M. S. M. Herath

Description: Department of Civil Engineering, Curtin University, Perth, Western Australia. Downscaling of climate projections is the most adopted method to assess the impacts of climate change at regional and local scale. In the last decade, downscaling techniques which provide reasonable improvement to resolution of General Circulation Models' (GCMs) output are developed in notable manner. Most of these techniques are limited to spatial downscaling of GCMs' output ...

Description: School of Civil and Environmental engineering, Yonsei University, Seoul, Korea. Regional frequency analysis is widely used to estimate more reliable quantiles of extreme hydro-meteorological events. The stationarity of data is required for its application. This assumption tends to be violated due to climate change. In this paper, four nonstationary index flood models were used to analyze the nonstationary regional data. Monte Carlo simulation was used t...

Description: Department of Biological, Geological and Environmental Sciences, University of Bologna, Italy. In Italy, growing urbanization is leading to a higher risk of flooding of small water courses, especially in steep catchments of limited area, where severe flash flood events can occur. The assessment of flash flood hazard requires new modelling tools that can reproduce both the rainfall–runoff processes in the catchment, and the flow processes in the drainage netw...
