MELODIES www.melodiesproject.eu
• The MELODIES project is exploi6ng diverse sources off Open and Linked Data to develop new applica6ons and technologies that benefit society.
• Two of the services that MELODIES will provide are: – Groundwater model services
• Driven by Open Data and Ci6zen Science – Crisis mapping services
• European Historical Flood Disaster Database

Numerical Models
8th Phase of the GEOSS Architecture ImplementaDon Pilot (jan-‐2015) … 4. Build toward the vision of the Model Web:
• Models are the codifica6on of the best understanding we have about physical phenomena and processes and should be further applied
• The vision of the Model Web is to serve as the basis for development of a dynamic web of models, integrated with databases and websites, to form a consulta6ve infrastructure where researchers, managers, policy makers, and the general public can gain insight into “what if” ques6ons
…and beyond: Zahorí (Dowser)
• Android applica6on to: – View groundwater model data
– Send new observed data to the model
• Makes use of the described REST Web Services to send and obtain model data

Models driven by ciDzen data: Numerical Models 2.0
How to incorporate crowd sensing data to the model • Overall principles:
– Ci6zen supplied absolute head levels aren’t useful (no unique way to measure it). – Ci6zen supplied changes in 6me are meaningful. – Observed measures in a controlled network are more valid, both in absolute or
rela6ve terms. – Computed (absolute) values must be corrected for each user according to the first
supplied absolute value.

What’s innovaDve? What’s the impact?
Groundwater model results as Linked Open Data (LOD)
Link geospa6al data with groundwater data. Basis to expand LOD to model results of different areas.
Model Web as consulta6ve infrastructure
Best understanding of physical phenomena. General public can gain insight into “what if” ques6ons.
Smart Regions Public informa6on extended to territories.
Numerical models 2.0: Models driven by ci6zen data
Public par6cipa6on in both direc6ons. Model’s quality increases with new observa6ons.

• The service will provide historical and actual situa6on informa6on for crisis management aggrega6ng Open Data
• Keeping track of floods in Europe for the ci6zen in: – Albania Austria Bosnia and Herzegovina Belgium Bulgaria Belarus Switzerland Czech Republic…
