Resultado final
The developed models and methodologies for landslide (debris flow and rock fall, etc.) hazard zoning have been prepared, with a scientific approach, to help in the determination of basic principles to be introduced in guidelines, codes and standards of practice. The developed approaches will be quite useful for technical and non technical administrators or planners or for insurances. Data collection methodologies, introduction of a GIS system, modelling principles and codification of results are fundamental elements and results.
End-users directly linked to the project helped in discussing the use of the results obtained and developed during the project itself. The Lombardy Region Geological Survey helped in the collection of existing laws adopted in Europe and in other countries. The Lombardy Region has already accepted the methodologies suggested through the project and some of the results have been introduced in technical specifications for land use planning and management, and for landslide hazard and risk evaluation and management.
Standard of practice, technical specifications for environmental, hazard zoning and civil protection laws are currently under revision by the end-users in collaboration with the Milano Bicocca research team. This result is aimed mainly at the relevant project end-users, or similar end-users (local and regional administrations). A strong impact is already foreseen on professionals and consultants who will be forced to adopt these standards for conducting their studies. Potential barriers to the exploitation of these results could be political or administrative; they could limit their final adoption.
The results of the project have been applied to different area both in Italy and abroad (Spain, Switzerland) and will be probably applied to more areas (Trentino Alto Adige, Italy, etc.).

Overview:
The SHETRAN landslide sediment yield model was applied to two focus basins, one in the Lombardy pre-Alps in Italy, the other in the central Spanish Pyrenees, to give debris flow spatial and temporal occurrence and basin sediment yield. Simulations were carried out for the current land use and for a possible future land use (either reforestation of hill slope meadows or replacement of burnt forest by grassland). Each land use was simulated for the current climate and for the projected 2070-99 climate. The dependency of debris flow occurrence and basin sediment yield on climate and land use could therefore be assessed. Electronic matrices were produced to contain the data for each combination of land use and climate and to allow easy comparison of the results. The matrices thus provide a basis for developing guidelines for land management to mitigate future debris flow occurrence and impact in the two focus areas.
Potential applications:
Selecting land management options to minimize debris flow occurrence and sediment impacts.
End-users:
The project end-users linked to the two focus areas.
Innovative features/benefits:
Predictions of debris flow occurrence and sediment yield for a range of possible future land uses and climates.
Market sector:
This outcome is aimed at the relevant project end-users, which are local planning and hazard assessment agencies.
Potential barriers:
The outcome was transferred to the end-users at the end of the project.
A training course related to the application and implementation of the WP3 (Small Basin Debris Flow Impact Model) was held on the campus of the Agricultural Faculty of the University of Padova (Agripolis) at Legnaro (PD). Sessions were organized over two days. September 10, 2002, was dedicated to the presentation of DEFLIMO and the 1-D and 2-D sub-models, and also to discuss the different types and characteristics of gully-channelled debris flow, limits of models, field of applications and data set input requirements.
A typical practical-individual technical session using ten dedicated-PCs was carried out in the GIS laboratory, September 11, 2002. A report entitled "Methodological guide: case studies and applications" was prepared and given to all participants. The PDF file of this document is available on the DAMOCLES Project Website (http://damocles.irpi.cnr.it/ ).
The DEFLIMO model was installed and is being used by the Torrent Control Agency of Trento Province, Italy, by the ARPAV-Avalanche Centre of Arabba in the Veneto Region, Italy, and by the "Associazione Italiana di Idronomia", Italy. Debris flow hazard assessments obtained from the outputs of the simulation model DEFLIMO were presented to other potential end-users, including the torrent Control Agency of the Valle d'Aosta Region, the Soil Defence Agency of the Veneto Region, Italy, and the Torrent Control Agency of the Tucumáan and Mendoza Provinces of Argentina. All these potential end-users proved interested in the results obtained.
Other dissemination and training activities have been carried out by the Milano-Bicocca team. In particular, an EC Workshop and a training course were organized in Milan.
1) Damocles workshop with end-users, Milan, 21 November 2002. A full-day workshop have been organized at Università Milano-Bicocca to present the Damocles activities to the end-users. During the workshop, all the Damocles partners presented the results of their activities. More than 50 end-users participated in the workshop, coming from different Italian administrations: Lombardia Region, Piemonte Region, Valle d�Aosta Province, Trento Province, Lecco Province, Italian Geological Survey, and others.
2) Damocles training course for the Lombardia Region end-user: 10-12-17-19 December 2002. Four full-day training courses were organized at Università Milano-Bicocca. 25 people from the Lombardia Region end-user were trained in the methodologies for debris-flow and rock-fall hazard assessment developed during the Damocles Project. Training on the 3D rockfall modelling approach developed by the University of Milano Bicocca team has been completed for some technical personnel.
Overview:
SHETRAN is a basin-scale hydrological and sediment yield modelling system. It contains a component for simulating the sediment yield arising from debris flows evolving from shallow landslides, as a function of land use and climate, in basins up to 500km2 in area. It has been enhanced using debris flow relationships determined elsewhere in DAMOCLES. It has been applied to two focus basins in the Pyrenees and pre-Alps to determine debris flow occurrence and sediment yield for a range of scenarios. These applications have provided experience in data assembly for the model, model performance and production of practical outputs. The latter include debris flow maps, and sediment yields as well as time varying output on water flows and sediment transport.
Potential applications:
Predicting the impacts of future land use and climate changes on debris flow occurrence and sediment yield at the basin scale.
The University of Newcastle runs the model. End-users interested in the results include planning and hazard assessment agencies, consultancies and other research organizations.
Innovative features/benefits:
No other model is known to be able to predict debris flow occurrence and sediment yield at scales of 500 km2 as a function of future land use and climate changes.
Market sector:
Hazard assessments and environmental impact assessments in mountain areas. There are significant implications for lives, livelihoods and infrastructure. SHETRAN should therefore be of interest to consultants and planning agencies.
Potential barriers:
Transforming the SHETRAN landslide model into a more user-friendly product which does not require the dedicated Newcastle team for its application.
Training end-users in its use.
