Participatory model assessment of earthquake-induced landslide hazard models

Miles, Scott - In: Natural Hazards 56 (2011) 3, pp. 749-766

The study described in this paper investigates the relative merits of two peer-reviewed earthquake-induced landslide models using participatory model assessment. The earthquake-induced landslide hazard models assessed are a simplified Newmark’s displacement model and a recently developed...

A hydrodynamic model for the Lower Rideau River

Ahmed, Ferdous - In: Natural Hazards 55 (2010) 1, pp. 85-94

A detailed hydrodynamic model of the Lower Rideau River system has been constructed using the Mike11 modeling system of the Danish Hydraulic Institute. This river system is complex, comprising of channels, local drainage areas, lateral inflows, and a number of water control structures. The model...

Methodology for Landslide Susceptibility Mapping by Means of a GIS. Application to the Contraviesa Area (Granada, Spain)

Fernández, T.; Irigaray, C.; Hamdouni, R. El; Chacón, J. - In: Natural Hazards 30 (2003) 3, pp. 297-308

This article presents a method to map landslide susceptibility in rock massifs using Geographical Information Systems (GIS). The method is based on making an inventory of rupture zones of different types of slope movements and then analysing the bivariate correlation of these with the factors...
