Overall Goal of this project is to contribute to landslide disaster reduction
along main transport arteries and on residential areas through study on
effective application of new technology on forecast, monitoring and treatment
of landslides in Vietnam and other areas in the Greater Mekong Sub-region
in close cooperation with Japanese universities and also the International
Consortium on Landslides (ICL). Through this joint activity, the following
effects are expected.
Development of Landslide risk assessment technology suitable for the targeted areas in Vietnam.
Capacity Development for research on landslide risk identification and
hazard mapping.
Social application over the regions (Vietnam and other areas in the Greater Mekong Sub-region).
|
Landslide risk assessment technology to reduce landslide disasters along main transport arteries is developed through the collaborative research based on the Japanese pioneer technology, and capacity development for the effective use of this technology is implemented in Viet Nam.
|
| 1. Wide-area landslide mapping and identification of landslide risk area |
- Identification of previous landslide sites from air and satellite photos
- Identification of the precursor stage of landslides by the
pattern analysis of digital surface model (DSM) of forest cover and others
- Formation of landslide risk map based on detailed field investigation
and analytical model such as Analytical Hierarchy Process method (AHP)
- Development of the technology to visualize the feature of
landslide
| 2. Development of landslide risk assessment technology based on soil testing and computer simulation |
- Development of undrained dynamic-loading ring shear apparatus
- Elucidation of the initiation mechanism and the dynamics of
post-failure motion of the targeted landslides
- Development of hazard assessment technology of the precursor
stage of landslides
| 3. Risk evaluation and development of early warning system based
on landslide monitoring |
- Selection of pilot area for landslide monitoring based on the field
investigation
- Development of the integrated automatic monitoring system for rainfall-groundwater-slope movement
- Establishment of early warning system suitable for the region
based on the landslide experiment on natural slopes with artificial rains
| 4. Preparation of integrated guidelines for the application of developed
landslide risk assessment technology |
- Prepare integrated guidelines for the application of developed
landslide risk assessment technology based on the Activities (1)-(3)
- Conduct workshops, research meetings and conferences for information
dissemination
