Assessment of small-scale landslide treatment in Nepal

Abstract

Landslides are major natural hazards in Nepal, and efforts are underway to treat smallscale landslides with people's participation. The main purpose of this study was to assess various aspects of the prevalent practice of landslide treatment followed by the Department of Soil Conservation and Watershed Management, Government of Nepal. Questionnaire survey and case study methods were used to collect the necessary information. It appears that the landslide treatment has been successful in stabilizing the major portion of the treated landslides. However, landuse improvement above the treated landslides, and drainage management inside and around the treated landslide sites were found to be inadequate. Also, the maintenance of constructed structures and vegetation was not satisfactory. The findings and recommendations of this paper will be useful in improving the landslide treatment in Nepal.

“…SBT have been widely used in Nepal to deal with erosion problems on slopes, especially for treatment of shallow-seated landslides associated with high way construction (Clark and Howell, 1992;Lawrance, 1994;Howell, 1999;Florineth et al, 2002;Sharma, 2004;Lammeranner et al, 2005;Devkota et al, 2006;Ojha and Shrestha, 2007;Mathema and Joshi, 2010). However, the majority of published literature is based on practical experience and not on scientific research that uses data about initial soil conditions and modes of failure.…”
