Benefit-Cost Analysis of Acquisition of Properties Subject to One-time-loss (Landslides)

Abstract

For a special class of hazards such as severe landslides, the expected level of damage is usually limited to two possibilities; zero damage or total loss (“one-time-loss”). A new approach is developed for Benefit cost Analysis of acquisition of properties subjec0 to non-recurring total loss. The equivalent annual probability of landslide is estimated for a given probability of a catastrophic landslide event within the next few years from geotechnical studies. The theoretical approach and assumptions are laid out and the proposed solution is explained through an example problem. Simplified solutions in tabular, graphical and equation formats are included.
