A GIS based air quality system for the Apulia region, southern Italy
A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

Estimating the spatial-temporal distribution of Radon releases from the K-65 silos
This study investigates the spatial and temporal distribution of Radon at the Department of Energy's (DOE) Fernald Environmental Management Project (FEMP), in southwest Ohio in 1999. It employs the United States Environmental Protection Agency's (EPA) Industrial Source Complex Short Term 3 (ISCST3) dispersion model, existing monitoring data and Geographic Information Systems (GIS) as tools to ...

Evaluation of AirGIS: a GIS–based air pollution and human exposure modelling system
This study describes in brief the latest extensions of the Danish Geographic Information System (GIS)–based air pollution and human exposure modelling system (AirGIS), which has been developed in Denmark since 2001 and gives results of an evaluation with measured air pollution data. The system shows, in general, a good performance for both long–term averages (annual and monthly averages), ...

A GIS-supported 3D approach for flood risk assessment of the Qu'Appelle River, Southern Saskatchewan
This research introduces a hybrid approach for flood risk assessment through GIS. The developed approach is based on the integration of hydraulic simulation and GIS analysis, which allows spatial-based visualisation and prediction of flood disaster. In particular, the Hydraulic Engineering Center River Analysis System (HEC-RAS) model is employed to simulate multi-scenario flood cases within a ...

Development of a GIS-based urban air quality modelling system for transport-related pollution
In recent years motor vehicles have become the dominant source of air pollution in metropolitan areas. Hence, the assessment of transport-related air quality is of major concern to policymakers and municipal planners. This paper describes an urban air quality modelling system for evaluating the environmental effects of transport related air pollution. A preliminary evaluation of the model has ...

Exploring nature-based solutions - The role of green infrastructure in mitigating the impacts of weather- and climate change-related natural hazards
Natural resource scarcity, climate change impacts, continued employment crises, public budget debts and economic recovery plans are some of the challenges that governments in Europe currently face. Moreover, Member States in the European Union (EU) need to continue building or rebuilding roads, sewage systems, levees, etc. (also known as grey infrastructure). Despite being essential for economic ...
