Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

Disasters

Natural disasters are impacting upon mankind with relentlessfrequency and intensity and have taken a heavy toll in recent years.

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

Mitigation

Risk assessment analysis allows the development of natural hazardmitigation planning.

Hazard Mitigationplanning is the process ofdeveloping a set of actionsdesigned to reduce oreliminate long-term risk topeople and property fromhazards and their effects.

Those plans if actuated allow to reduce: economic losses, killingand injuring, historical and architectural heritage damages.

Introduction The RiskBox project Conclusions and perspectives

Risk analysis and GIS

R = H ∗ V ∗ E

Hazard : Where, how oftenand with what intensity doevents occur?

Vulnerability : What is theextent of damage at a givenevent intensity?

Exposure : Where theelements at risk are locatedand what is their value?

Most of the questions have strong geospatial component.

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

RiskBox

RiskBox is a project which includes:

1 tool, open source procedures and numerical models fully GISintegrated in the GRASS GIS open source software;

2 graphical user interface (GUI) developed in desktop / Webenvironment to provide user friendly access to the GISmodules and geographical data;

3 geospatial data models, to store and share information onhazard areas and protection works;

4 education to enrich knowledge and personal skills in riskmanagement, and risk resilience.

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

GRASS-GIS

GRASS (Geographic Resources Analysis Support System) isa a high-quality free open source geospatial software thatsupports raster and vector data in two and three dimensions.

The integration of new functions and model can be easilyconducted using its highly advanced geographic libraries, asshown by the following models alreay implemented inGRASS.

rock falls (r.rockcone)

flooding (r.inund.fluv, r.damflood r.hazard.flood, etc.)

landslide / debris-flow (r.dfwalk, r.debrisflow, r.massmov,r.lhm)

avalanches (r.avalanche)

tsunami (r.tsunami,r.impact.tsunami)fire (r.ros/r.spread/r.spreadpath)

etc.

11 / 25

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

r.rockcone

r.rockcone implement a quick and low-costdetermination of areas endangered byrockfalls following an heuristic approach: ablock starting from a source will traveldown the slope and stop at the intersectionpoint of the topography with a so calledenergy line drawn from the source pointand making an angle ϕ with horizontal.

Introduction The RiskBox project Conclusions and perspectives

r.inund.fluv

We developedr.inund.fluv, a new GIScommand that allows touse the result of a 1Dhydrodinamic model(HEC-RAS, Basement,MIKE11, etc) to evaluate2D flood maps.

13 / 25

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

r.damflood

r.damflood is rather a 2D GIS embedded numerical model whichevaluate flooding map in case of dam break.

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

r.dfwalk

r.dfwalk is command which implementdfwalk, a conceptual model for thecalculation of the area involved by debrisflow, modified to be used as a tool for riskassessment at the municipality level.

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

r.massmov

r.massmov is an open-source model forsimulating fast landslide phenomenaover complex topographies.It has been developed to meet theexpectation of innovative early warningsystems modeling services.

Introduction The RiskBox project Conclusions and perspectives

Web Processing Service

The Web Processing Service (WPS) is the standard used toanalyse spatial data from the web. GIS model and tools can beserved on the web by using this standard. Real-time analysis canbe performed changing the input data.

20 / 25

Geomatics for management and mitigation of risk

Introduction The RiskBox project Conclusions and perspectives

Web Processing Service

Two are the main advantages of the web processing services:

Interoperability: software applications written in variousprogramming languages and running on various platforms canuse web services to exchange data over Internet.

Usability: web services easily allow software and services fromdifferent companies and locations to be combined easily toprovide an integrated service.

ProtectMe

With the purpose to improve the management ofrisk reduction initiatives, the Swiss Federal Officefor the Environment (FOEN) launched theProtectMe project, an initiative of the SwissConfederation to standardize and capture datarelated to natural hazard control/mitigationinfrastructure.

Education

University of Applied Science ofSouthern Switzerland and Gter ,a spin-off company of theUniversity of Genoa (Italy), arealso cooperating with their tasksin organize professional courseabout risk management.

Two examples are:

RiskLab bachelor course (SUPSI);

continuity education program of SUPSI and Gter, which arespecifically performed on Open Source geospatial tools.
