Development of Landslide Risk Assessment Technology
   along Transportation Arteries in Viet Nam



 Group 1: Project coordination, Education and Public Awareness
 Leaders: Sassa, Tam, Ochiai , Miyagi, Tien, Quang and Vinh

Application of risk assessment technology and examination of practical and effective preparedness to mitigate landslide disasters.

Coordination and implementation of Education activities in Vietnam, the Greater Mekong Sub-region as well as in Japan

Coordination and implementation of meetings (symposia, workshops, public awareness, project group meetings, and publication in print and in web.

All key persons from Japan and Vietnam will jointly discuss the plan and the process of the project and coordinate the activities.

 Group 2: Landslide Mapping
 Leaders: Toyohiko Miyagi and Dinh van Tien (ITST)

Identification of landslide topography from air and satellite photographs over the targeted areas

Mapping of topographic types and landslides over the targeted areas.

Searching locations of slopes with characteristics of precursor stage of landslides

Rating risk of identified landslides by Analytical Hierarchy Process method. Field investigation and field observation to evaluate identified landslide slopes

Integrated landslide mapping over the targeted areas

 Group 3: Risk Assessment
 Leaders: Kyoji Sassa and Lam Huu Quang (ITST)

Development of landslide testing apparatus suitable for landslide risk assessment in Vietnam.

Geo-mechanical classification of landslide types posing serious effects in Vietnam

Elucidation of initiation mechanism and moving dynamics of selected sites by filed investigation, sampling and testing

Calibration of risk assessment technology to be developed in the already failed landslides

Risk assessment of initiation and motion of precursor stage of landslides and potential landslides by the developed technology


 Group 4:Landslide Monitoring
 Leaders: Hirotaka Ochiai and Huynh Dang Vinh (ITST)

Selection of monitoring sites in cooperation with other two groups and regional conditions

Selection of appropriate monitoring methods based on the field investigation and social conditions

Installation of monitoring equipments

Establishment of continual monitoring and maintenance system.

Development of suitable data collection, data transfer and web-showing system.

Establishment of early warning criteria and system applicable for the targeted sites.
