Develop a web-interface for inputting field data to an existing landslide prediction model, and allow the user to download the model outputs for visualization, interpretation and identification of landslide risk reduction measures. By making this model available to local engineers and technicians in developing countries it will be possible for them to work with residents to diagnose the causes of landslides in the most vulnerable ‘shanty-town’ communities. It has been shown that this method can lead to the construction of effective landslide risk reduction in such communities and large events can cause loss of life, require community relocation, and cost millions of dollars.

CHASM (Combined Stability and Hydrology Model) is an integrated slope hydrology/slope stability software package that aids the assessment of slope stability conditions. It is designed to help the user estimate the effects on slope stability of selected storm events, surface vegetation cover, slope plan curvatures and other important slope and material properties – it was the first slope stability code to incorporate dynamic hydrology (the key mechanism in rainfall-triggered landslides).
To use models like CHASM requires a certain level of modelling and geotechnical expertise in order to make a realistic analysis of a slope. The aim of this development is to make the technology available to government technicians and engineers who don’t have any modelling expertise but who have knowledge of the local slopes, basic field data and community accounts of slope processes.
See www.chasm.info to find out about the software and its applications See www.mossaic.org for the wider context, and to see the difference that understanding slope processes can make when it comes to reducing the risk to communities.
