Urban Storm-Water Quality Management: Centralized versus Source Control
2010
The continuous growth of urban areas and the increasing public awareness of the environmental impacts of storm water have raised interest on the quality of the receiving water bodies. In the past two decades, many efforts have been directed at improving urban drainage systems by introducing mitigation measures to limit the negative environmental impacts of storm water. These mitigation measures are generally called best management practices (BMPs), sustainable urban drainage systems, or low impact developments, and they include practices such as infiltration and storage tanks that reduce the peak flow and retain some of the polluting materials. Choosing the best mitigation measure is still …
Analisi economica degli interventi distribuiti di gestione dei deflussi urbani
2011
L’applicazione degli interventi distribuiti di gestione dei deflussi urbani è stata effettuata finora in maniera piuttosto disomogenea in Europa ed in particolare in Italia, probabilmente anche in seguito alle difficoltà legate alla valutazione dell'efficienza idraulica ed economica di tali interventi. Obiettivo del presente lavoro è quello di analizzare l’aspetto economico di alcune BMP per quanto riguarda sia i costi di realizzazione sia quelli di manutenzione, nell’ottica della valutazione dell'efficienza delle BMP e delle problematiche relative alla implementazione di sistemi di drenaggio nel contesto della pianificazione territoriale. Attraverso la classificazione, la descrizione e l’a…
Current European approaches in highway runoff management: A review
2022
Highway runoff is one of the most significant non-point sources of pollution for the terrestrial and aquatic environment with biological, physical, and chemical effects. Considering local characteristics, treatment practices, and determining factors are essential for highway runoff management. The aim of this paper is to survey the review of highway runoff management in Europe with emphasis on runoff characterization, treatment, and modeling approaches and identifying possible knowledge gaps exists based on our review. The results showed that highway runoff has spatiotemporal variation, which is the main factor in the regional selection of the best management practice (BMP). Also, recent st…
Long Term Efficiency Analysis of Infiltration Trenches Subjected to Clogging
2018
Abstract: In recent years, limitations linked to traditional urban drainage schemes have been pointed out and new approaches were developed introducing more natural methods for retaining and/or disposing of stormwater. Such practices include infiltration and storage tanks in order to reduce the peak flow and retain part of the polluting components. The impact of such practices on stormwater quantity and quality is not easily assessable because of the complexity of physical and chemical processes involved. In such cases, integrated urban drainage models may play a relevant role providing tools for long term analysis. In this study, the effect of the clogging phenomenon has been assessed by m…
Resilience of Mediterranean Forests to Climate Change
2017
In the Mediterranean region, forests play a key role in the welfare of urban and rural peoples, by providing highly appreciated marketed goods as well as high value but nonmarket services. Anthropogenic climate change entails a significant impact on Mediterranean forests, such as the reduced species diversity, high density, pest, and diseases. In this chapter, we present the achievements of the project LIFE ResilForMed (Resilience of Mediterranean Forests to climate change), as Sicilian responds on adaptation and mitigation to climate change: (i) map of Sensitivity Forest Areas to desertification of the Sicilian region; (ii) list of bird indicators showing sensitivity to desertification in …
Modelling urban stormwater impact mitigation by using bmps and storage tanks
2005
The continuous growth of urban areas and the increasing public awareness about environmental impact of stormwater raised high interest on quality impact on the receiving water bodies. Indeed, in the last decades, large efforts have been provided for improving urban drainage systems in order to mitigate environmental impacts. In the present paper, a simplified modelling approach has been developed in order to evaluate the mitigation efficiency of different BMP schemes including infiltration and storage facilities and both considering possible distributed controls and centralised structures. The main goals of the research are the simulation of BMP efficiency in different operational condition…
Évaluation du colmatage de tranchées d'infiltration selon le type de sol : analyse à long terme
2010
In recent years, limitations linked to traditional urban drainage schemes have been pointed out and new approaches were developed introducing more natural methods for retaining and/or disposing of stormwater. Such practices include infiltration and storage tanks in order to reduce the peak flow and retain part of the polluting components. The impact of such practices on stormwater quantity and quality is not easily assessable because of the complexity of physical and chemical processes involved. In such cases, integrated urban drainage models may play a relevant role providing tools for long term analysis of infiltration structures efficiency. In this study, the effect of the clogging pheno…
A paradigm of extreme rainfall pluvial floods in complex urban areas: the flood event of 15 July 2020 in Palermo (Italy)
2021
Abstract. In the last few years, some regions of the Mediterranean area have witnessed a progressive increase in extreme events, such as urban and flash floods, as a response to the increasingly frequent and severe extreme rainfall events, which are often exacerbated by the ever-growing urbanization. In such a context, the urban drainage systems may not be sufficient to convey the rainwater, thus increasing the risk deriving from the occurrence of such events. This study focuses on a particularly intense urban flood that occurred in Palermo (Italy) on 15 July 2020; it represents a typical pluvial flood due to extreme rainfall on a complex urban area that many cities have experienced in rece…
Resilienza delle foreste Mediterranee ai cambiamenti climatici - Guida al progetto [Resilience of Mediterranean forests to climate change – Project g…
2017
The overall objective of the project LIFE11+ ENV/IT/000215 RESILFORMED – Resilience of Mediterranean forests to climate change is to preserve the forest systems from the risks due to climate change, through naturalization processes, increased biodiversity and improved responsiveness, in the recovery process, coming from destabilizing events. The specific objective is to implement a regional forest policy able to increase resilience capacity of Sicilian forests, improving their ecosystem capacity and fostering the biodiversity preservation. The project has proposed to pursue five concrete results: 1) drafting guidelines for effective Mediterranean forest management with respect to climate ch…
Linee guida per la valutazione della resilienza delle foreste Mediterranee ai cambiamenti climatici [Guidelines for assessing the resilience of Medit…
2017
We have defined optimal management models for improving or strengthening the resilience of forest environments: in particular, five best management practices aiming at improving the Mediterranean forests resilience with reference to the desertification risk. The 5 Best ManagementPractices are: BMP1 - Actions favoring mixing of species and hydrogeological stability of forests; BMP2 - Renaturalization of forest plantations; BMP3 - Remedial measures and restoration of degraded forests; BMP4 - Actions aimed at enhancing complex structural forests; BMP5 - Actions favoring connectivity in agro-forestry systems. The best management practices have been then applied adapting them to 16 different int…
