- modelling slope stability in areas of seasonal freeze-thaw (examine the spatial relationship between surficial materials, terrain derivatives and historic slide features)
- data models for geotechnical data (standards for obtaining, presenting and analysing geotechnical data in a spatial context.
- what are your interests? I can suggest the ever-boring interpolation method comparative analysis, 3d modelling of slip plane or rotational slope failure? GIS will be the tool unless you want to get into the algorithmic implementation and development for something that hasn't be developed yet
on to you
