Final CircularInternational symposium on sediment disasters
under the influence of climate change and tectonic
activity (2nd)
Scheduled at 15th and 16th September, 2011
Venue: Centennial Hall, Hokkaido University, Sapporo, Japan
Sponsored by Japan Society of Erosion Control Engineering
Website:http://www.jsece.or.jp/event/symp/aps2011/index.html

Aims & Scope:
Climate change and tectonic activity areknown globally to be serious causes ofsedimentdisasters.
Damagefromsediment disasters is widely reported inthe Asian-Pacific region. The highintensity rainfall from typhoons andcyclones increases the probability of
localized landslides and debris flows.
Large scale sediment disasters that havebeen recently reported are also associatedwith earthquake and volcanic activity.
Scientists and land managers need totackle sediment disasters under theinfluence of a changing climate andvariable tectonic activities. Some of thegeomorphic and hydrologic processes andthemagnitude of disasters canunexpectedly overwhelm our scientificknowledge, predictive capability, anderosion control or countermeasuretechniques. New scientific approaches andmitigation technologies, including land use planning and disaster prevention, should bedeveloped for finding effective solutions to potential disasters. Incorporation of thelatest sciences and technologies from local, regional, and global perspectives ingeomorphology and hydrology are required to improve prediction of sediment disasters
and develop warning systems under changing environments.
The aim of this symposium is to assemble and discuss sediment dynamics under theIssued on August 26, 2011

influence of climate change and tectonic activity in the Asia Pacific region. We will
share scientific knowledge for helping understand and predict processes in the various
fields of hydrology, geomorphology, geology, meteorology, and hydraulics. We will also
integrate knowledge for the mitigation of disasters and providing countermeasures for
erosion control. We invite papers from a broad range of disciplines that are interested inthese perspectives in the Asia-Pacific region. There will be keynote lectures at thesymposium by invited speakers and poster presentations by associated participants.
Scientists, technicians and land managers who are interested in this symposium,
especially within Pacific Rim countries, are welcome to participate and contribute to thesymposium.
We will design a more interactive program for the symposium. In the workshop session,discussion among young scientists will be coordinated and focus on emerging issues ofthe processes related to sediment disasters and methodologies for effective evaluation ofthese processes. We are also planning to produce a special issue to be published in aninternational journal. This will help achieving more widespread communication ofpresentations and contribution on post-symposium discussion.

Key topics of this symposium:
Field observation and analysis of sediment dynamics and disasters
Geomorphic and hydrological processes in sediment transport
GIS and remote sensing for analysis and assessment
Countermeasures for restoration and prevention
Risk management and hazard mapping
Watershed conservation
