A Proposal for a Geospatial Database to Support Emergency Management

ABSTRACT

The basic procedure of the Italian Civil Protection Department aims at reducing disaster losses by giving prominence to a proactive strategy, focusing on prevision and prevention of hazard events rather than postdisater activities. Italian law commits municipalities to produce Emergency Plans that include risk scenarios as well as all data required for emergency management, such as structures, infrastructures and human resources. However the law in the matter of Civil Protection does not supply information about how to produce and archive necessary data for emergency planning and management. For this reason, we propose a standard methodology to create a geodatabase using GIS software, to collect all data that could be used by municipalities to create Emergency Plans. The resulting geodatabase provides a tool for hazard mitigation planning, allowing not only the identification of areas at risk, but also the structures, infrastructures and resources needed to overcome a crisis, thus improving all strategies of risk reduction and the resilience of the system [1].

A model for shallow landslide susceptibility - R.SHALSTAB

This model allows to apply the algorithm developed by Montgomery and Dietrich (1994) in GRASS GIS. According to these authors, the SHALSTAB model predicts the critical rainfall necessary for slope failure throughout a study area (Montgomery and Dietrich, 1994).

Requested input and output.

The command requires some input:

  • DEM a digital terrain model of the study area;
  • Raster map or single value for soil cohesion (N/m^2);
  • Raster map or single value for soil friction angle (°);
  • Raster map or single value for soil density (kg/m^3);
  • Raster map or single value for vertical thickness of soil (m);
  • Raster map or single value for hydraulic conductivity k (m/h);
  • Raster map or single value for root cohesion (N/m^2); (default = 0)
  • Raster map or single value for wet soil density (kg/m^3). (default = 2100)

The output are:

  • a landslide susceptibility map (value range from 1 to 7):
    • 1 Unconditionally Unstable
    • 2 (0-50 mm/day)
    • 3 (0-100 mm/day)
    • 4 (100-200 mm/day)
    • 5 (200-400 mm/day)
    • 6 (400-1000 mm/day)
    • 7 Stable
  • a map for of critical rainfall map (mm/day)

The predictive index of this model (stability index) is expressed in mm day−1 of critical rain and is variable on a scale of values, where lower values indicate a greater propensity for instability and higher values indicate a greater propensity for stability.

Presentazione del laboratorio EuroCOLD - European Cold Laboratory Facilities

Mercoledì 15 maggio 2013, ore 11.00

Edificio U2, Aula 7, Piazza della Scienza 3, Milano

Ricercatori all'interno del laboratorio EuroCOLD

EuroCOLD (European Cold Laboratory Facilities) è uno tra i più grandi e moderni laboratori ad atmosfera controllata con temperature fino a -50C°, per la conservazione e lo studio del ghiaccio proveniente dai più importanti siti dei programmi internazionali di ricerca sul clima dall’Antartide alla Groenlandia alle Alpi.

Il laboratorio, realizzato dall’Università di Milano-Bicocca e dal Dipartimento di Scienze dell'Ambiente e del Territorio e di Scienze della Terra, è coordinato da Valter Maggi, professore associato di climatologia dell’Università di Milano-Bicocca e responsabile italiano del progetto EPICA (European project for ice coring in Antarctica).
