International Symposium on

Water and Sediment Disasters in East Asia

March 23-25, 2010 KYOTO, JAPAN

East Asia frequently suffers from various natural disasters such as those caused by earthquakes,

typhoons, heavy rainfalls, floods, tsunamis and storm surges. This symposium provides an opportunity for

researchers/decision-makers working on water and sediment disasters to exchange ideas and expertise in

an international framework. Join the symposium, one may find different opinions from our invited lecturers

on recent disasters caused by the 2008 Great Sichuan Earthquake in China and the 2009 Typhoon

Morakot in Taiwan. The symposium also intends to share with attendees the newest research results in

climatic variation, urban flood/ inundation, sediment yield/transport, fluvial process and coastal erosion,

from faculty members, researchers and graduate students of Kyoto University as well as invited experts

from China, Korea and Taiwan.

This symposium is jointly organized by RCFCD (Research Center for Fluvial and Coastal Disasters,

Disaster Prevention Research Institute, Kyoto University) and GCOE-HSE (Kyoto University Global Center

for Education and Research on Human Security Engineering in Asian Megacities). The symposium

consists of a one-day seminar at the Obaku Plaza of Kyoto University and a two-day field trip for invited

overseas lecturers to the Hodaka Sedimentation Observatory of RCFCD. The symposium proceedings

including the full papers of all presentations in both oral and poster sessions are freely distributed at the

symposium venue on March 23, 2010. You are welcome to the symposium!

Research Center for Fluvial and Coastal Disasters

Disaster Prevention Research Institute, Kyoto University

The Center promotes in-depth studies of fluid and sediment processes that may bring about serious

disasters and environmental changes, frequently through chain reactions, to watersheds, reaches,

reservoirs, estuaries and coastal oceans. These studies are inherently interdisciplinary and are covered by

the Center's five research sections: the Sedimentation Disasters; the River Disaster Prevention System;

the Urban Flood Control; the Coastal Sedimentary Environment and the Field Research Section for Fluvial

and Coastal Hazards. The Center's unique facilities are open to the partners for field and experimental

studies on disaster prevention and environmental preservation in the river-coast system. With these

facilities actively promoting collaborative researches, the academic staff at the Center has developed

cutting-edge technology for predicting complex processes in hydrosphere, together with disaster reduction

methodology. (Visit RCFCD online at http://www.dpri.kyoto-u.ac.jp/~rcfcd/) Kyoto University Global Center for Education and Research on

Human Security Engineering in Asian Megacities

This GCOE Program is funded by Japanese Ministry of Education, Culture, Sports, Science and

Technology, in order to "strengthen and enhance the education and research functions of graduate

schools, to foster highly creative young researchers who will go on to become world leaders in their

respective fields through experiencing and practicing research of the highest world standard." In this

five-year program, Kyoto University will establish a new discipline "urban human security engineering" and

create a network of overseas bases for research and education in Asian-wide scale to foster next

generation researchers and high-level practitioners. Through this program, we will contribute greatly to

solving human security issues in Asian megacities.
