Strategic Master Plans

The MEDIWAT Project (Sustainable management of environmental issues related to water stress in Mediterranean Islands) aims to provide innovative and sustainable technical, operational and managerial solutions for tackling problems caused by water resources-quality worsening and shortage in the Mediterranean insular context. The project brings together partners from six Mediterranean islands: Sicily, Cyprus, Corsica were considered large islands because of their area and hydrological behavior. Conversely Crete, Malta and Balearic Islands were considered small islands. A detailed analysis of current and future conditions relating to freshwater availability, quality and use has been carried ou…

Efficiency of Wave Energy Converters off the Sicilian Channel

2019

This paper presents a preliminary analysis on efficiency of wave energy converters off the Sicilian Channel (Italy) carried out using the SNL-SWAN spectral model (”Sandia National Laboratories – Simulating WAves Nearshore”). This open source numerical code makes possible to calculate the power extracted from wave energy converter (WEC) devices, arranged in arrays. The WEC arrays were located parallel to the coastline, near the 20 m bathymetric isoline. Three devices were tested: Pelamis, Wave Dragon and Oyster 2; one of the input data of the numerical model is the WEC power matrix, expressed as a function of the wave height and period. This matrix was determined experimentally by the protot…

Uncertainty estimation of a complex water quality model: GLUE vs Bayesian approach applied with Box – Cox transformation

2010

In urban drainage modelling, uncertainty analysis is of undoubted necessity; however, several methodological aspects need to be clarified and deserve to be investigated in the future, especially in water quality modelling. The use of the Bayesian approach to uncertainty analysis has been stimulated by its rigorous theoretical framework and by the possibility of evaluating the impact of new knowledge on the modelling estimates. Nevertheless, the Bayesian approach relies on some restrictive hypotheses that are not present in less formal methods like GLUE. One crucial point in the application of Bayesian methods is the formulation of a likelihood function that is conditioned by the hypotheses …

THE IDENTIFIABILITY ANALYSIS FOR SETTING UP MEASURING CAMPAIGNS FOR INTEGRATED WATER QUALITY MODELLING

2010

Identifiability analysis enables one the quantification of the number of model parameters that can be assessed by calibration with respect to a data set. Such a methodology is based on the appraisal of sensitivity coefficients of the model parameters by means of Monte Carlo runs. By employing the Fisher Information Matrix, the methodology is able to gain insights with respect to the number of model parameters that can be reliably assessed. The paper presents a study where identifiability analysis is used as a tool for the setting up of measuring campaigns for integrated water quality modelling. The analysis has been applied to a real case study characterized by a partially urbanized catchme…
