Abstract
With an increase in urban population, lands that have been considered marginal for housing development are being utilized for construction of buildings in order to accommodate the increased population. This trend is significantly increasing in the capital city of Kathmandu, Nepal. Utilization of marginally stable lands such as river bank, steep slope, and foot of mountain frequently trigger landslides. This study presents a case study pertinent to the recent collapse of a building that was constructed within a steep slope located close to a river bank. The field visit, geotechnical investigation and pertinent slope stability as well as deformation analysis shows that rise in water table due to continuous rainfall triggered the landslide. Moreover, construction of house within the marginally stable slope contributed in triggering the landslide.
