ECO-HYDROLOGICAL RIVER ASSESSMENT IN THE GEUM RIVER
BASIN, KOREAJEONGKON KIM (1), SANGYOUNG PARK(2), …

Artificial changes of water quality, flow regime and structures in rivers may lead tophysical and ecological changes throughout waterways and their floodplains. A preliminary
assessment of the Geum River basin in Korea was conducted by a multi-disciplinary team.
Based on the major events which might have affected the ecological system, a conceptualmodel was formulated to guide desktop and field studies, modeling and scenario evaluations.
The result of hydrological analysis indicated that the construction of the Daecheong
Multipurpose Dam (DMD) in the Geum River basin has altered flow magnitudes andreduced the river’s flow variability. Changes are evident in the magnitude of medium andsmall flows and the river experiences increased low flows during the dry season. As a result,fewer sensitive riffle-benthic species were observed in the reaches downstream of theDaecheong Multipurpose Dam due to the reduction of suitable habitat conditions such as
riffle-pool sequences. Black shinner (an endangered fish species) was selected and analysed
to explore relationships between flow regime change by dams and changes to its preferredhabitats. The results of this study provide fundamental information from which to develop
more sophisticated flow-ecology relationships and revised reservoir operation plans thatconsider the flow requirements of the downstream river ecosystem.

TOKYO WATER DISASTER AND DROUGHT CRISIS LOOMING NOWNOBUYUKI TSUCHIYA (1)(1): NOBUYUKI TSUCHIYA, Ph.D.

When we think about flood damage in Tokyo, it is a necessary to focus on four kinds
flooding method in Tokyo district.
In downtown area, ground subsidence came up to 5m by pumping large amount ofgroundwater in the course of high economic development, and formed a vast below sea
level area in the capital region. Such low land, it is necessary to pumping drainage 365 daysa year to keep land dry and above water. In such low-lying areas, there is a risk of three typesof flood, such as "River flooding" caused when embankment collapsed, "overland flooding"caused by lack of drainage function, and water damage caused by “storm surge” in land
below sea level.
If further embankment and sluices collapsed in the earthquake, there is also a danger of
immediately seawater infiltration, which is called "earthquake flood". In other words, Tokyo
has a possibility of flood occurrence even without a drop of rain water. Indicating themeasures against these issues. It was to the simultaneous approach to flood control anddrought management add river restoration as a result.

NEW TECHNICAL PERSPECTIVES TO BREAK A POSITIVE PATH
FOR THE ACTIVITIES OF RIVER RESTORATION IN KOREAKYUHO KIM (1)(1): Director of the Green River Research Center

River Restoration has been become the center of public interest since early
1980s in the most of developed or developing countries and also Asian countries.
It would certainly be helpful to improve our quality of life and earth environment
damaged or deteriorated by the river development for economic activities during
last 100 years. It’s destined to restore the river and its ecosystem for biodiversity
and sustainable environment in this lonely planet to hand down our nextgenerations.
There have so far been implemented a number of river restoration projects in
Korea, i.e., upgraded and changed revetments with bio- or natural materials,
reach or channel scale restorations, a few river spatially restoration projects, andsome removal of weir or dam for fish passage, etc. It’s, however, not sure to saythat how many projects have been accomplished in success compared to the basic
river restoration principles and goals, objectives in detail.
Therefore, It would be a good opportunity to discuss and talk about our status
and situations of river restoration works in Korea, whether it goes to moredesirable ways, its effectiveness and realistic results, what we have done or not
for the better or best river environments as we have intended or goaled, what wehave really learned or not in the view of scientific and technological approaches
or implementations, or what kinds of science and technology are necessary, etc..

ADAPTIVE MANAGEMENT FOR ECOSYSTEMS RESTORATION IN
HAIHE BASIN

Beijing, 100038, China

Climate change will affect ecosystems through a number of mechanisms,
involve a spectrum of human–climate–environment interactions, so policy andmanagement for ecosystems conservation and restoration should be adapted tomitigate the impacts. As uncertainties are associated with specific areas
vulnerable to climate change, a comprehensive study is necessary to clarify thelinkages between ecosystems and climate, to improve understanding of the
responses of ecosystems to climate change, which is the basis of management
adaptation. Based on the background of Haihe basin, a complex system consistsof mountain area, plain rivers, wetlands and estuary in the north of China, aregional scales study is carried out for the formulation of adaptive management
strategies on the resilience of ecosystems under scenarios of climate change. The
study closely linked with ecological water quantity and quality of seasonal rivers.
Through data analysis and models verification, environmental changes, trends
and their effects on ecosystems are introduced, vulnerability analysis to climatechange is done to identify future priorities, a brief overview of regional
restoration planning efforts is given and restoration needs and techniques in thedesign, planning, and regulatory operation are discussed. The preliminary
research results have been applied to the planning and management of water
resources and flood control practice to reflect the impacts assessment of climatechange.
