AQUAGRID: an extensible platform for collaborative problem solving in groundwater protection

Abstract

AQUAGRID is the subsurface hydrology computational service of the Sardinian GRIDA3 infrastructure, designed to deliver complex environmental applications via a user-friendly Web portal. The service aims to provide to water professionals integrated modeling tools to solve water resources management problems and aid decision making for contaminated soil and groundwater. In this paper, the AQUAGRID application concept and enabling technologies are illustrated. At the heart of the service are the computational models to simulate complex and large groundwater flow and contaminant transport problems and geochemical speciation. AQUAGRID is built on top of compute-Grid technologies by means of the EnginFrame Grid framework. Distributed data management is provided by the Storage Resource Broker data-Grid middleware. The resulting environment allows end-users to perform groundwater simulations and to visualize and interact with their results, using graphs, 3D images and annotated maps. The problem solving capability of the platform is demonstrated using the results of two case studies deployed.

Groundwater flow model management and case studies in Emilia-Romagna (Italy)

“…La Water Framework Directive (2000/60/EC) indica che le Autorità di Bacino devono dotarsi di strumenti modellistici per la gestione della risorsa (Puma e Bertolo, 2012). Altri esempi di modellistica orientata alla gestione delle acque sotterranee sono presenti in Barazzuoli et al (2008), Bonomi et al (2012), Passadore et al (2012), Lecca et al (2009). Questo è il quadro di riferimento all'interno del quale si colloca il presente lavoro, che intende descrivere, mediante alcuni modelli di flusso sotterraneo degli acquiferi della pianura dell'Emilia-Romagna, il processo di sviluppo sopra citato.…”

(Cidu et al, 2009). Les teneurs élevées en silice dans l'eau de consommation, comme c'est le cas dans la zone d'étude pourraient avoir pour conséquences des manifestations pathologiques au niveau du poumon (Eblin et al, 2014).…”

Grid Technology Reliability for Flash Flood Forecasting: End-user Assessment

“…This work is based on the results of researches on environmental problem-solving based on Grid technology. As mentioned in [8,18,20,25,37], Grid appears as an efficient technological solution to integrate factual data and dedicated tools among multiple stakeholders through an e-collaboration portal and throughout the expertise process [30,37]. exhibit the Sardinian Grid infrastructure, GRIDA3, dedicated to enable the sharing of skills, tools and resources for multiple environmental topics, in particular hydrology.…”

“…The seminar of Crisis Management Initiative group held at Helsinki on 11-14 September 2003 defined the challenge of interoperability in crisis management as the connection of participants playing different roles at different locations with specific information requirements but following the same sequence of the crisis events. The design of Grid architecture, as e-collaboration platform gathering heterogeneous resources in a "unified large-scale computational resource" [21], seems to make this interoperability issue possible [8,18,30,33,37]. Following this idea, scientists and experts in hydrology could be gathered in a dedicated virtual organization.…”
