Matrix approach

The matrix-assessment approach (DeGraff and Romesburg 1980) is an objective and quantitative method for establishing an index of instability over an area and evaluating landslide susceptibility. It is based on measured attributes of the bedrock, slope and aspect from aerial photo interpretation and field work and a landslide inventory. The total areas covered by landslides were placed in each appropriate cell and the amount of landslide terrain with the same particular combinations of bedrock, slope or aspect units was identified. A management unit matrix was constructed from all bedrock, slope and aspect combinations for landslide locations, giving rise to different management units within the matrix.

[Page 359]

Based on this method a quantitative landslide susceptibility zonation was obtained by grouping all the susceptibility values into classes. A non-hierarchical clustering method (Anderberg 1973) using a W function, by minimising the sum of squared deviations about the three equally distributed groups, was adopted to obtain susceptibility classes for the final landslide susceptibility classification (DeGraff and Romesburg 1980). As all of the attributes considered in the method may be easily measured from field research and aerial interpretation, little room is left for personal judgement, hence this is a quantitative assessment. The method was designed for large areas of wild lands. [...] The use of the GIS matrix method (Fig. 7) has been made possible by the development of microcomputers and software over the last two decades.

Anmerkungen

Although in most places nearly identical with exactly the same references, no hint is given that this text comes from another source.

The reference for Baeza (1994) is missing in Hja. Due to shortening the meaning of one of the sentences at the end has been changed into its opposite.
