Theme I: Water Resources Assessment Ms GAO Ge (China)

8

To learn and investigate literatures about adaption to changes in water resources availability in China Research progress and problems Basic conception Methods and indices Case studies on vulnerability analysis and adapt to changes in

water resources availability

Collected research achievements and practices on WRA linking to Climate prediction. Case study: water resources pre-assessment based on the clim

ate prediction on Yellow River Basin

Multiple-hydrological models were set up in NCC at basin and national scale

Hydrological modeling for different temporal-spatial scale

VIC (Variable Infiltration Capacity))

SWAT (Soil Water Assessment Tool)

Floodarea Model

Monthly Water Balance Model

HBV Model

VIC –National scale Monthly Water Balance Model - Four main river basin

SWAT: Key mesoscale watersheds Floodarea model-delineation of flooded areas

HBV model-Poyang Lake

Theme I: Water Resources Assessment Ms Hwirin Kim (ROK)

10

Develop Dynamic Water Resources Assessment Tool

Function: Assessment of water availability in consideration of surface and ground water, land use changes, and climate changes

Developed as a public domain SW System development and pilot application in

Korea (2015) Pilot application in WMO RA II (2016) Report to WMO for dissemination (2017)

Theme II: Flood Forecasting - Dr Sergey Borshch (Russia)

12

Complex analysis of 2012-2013 hydrometeorological conditions in the amur river basin figured out the following principal factors of the catastrophic 2013 flooding in the amur river basin:

(a) hydrological conditions prior to the flooding; (b) meteorological conditions of 2013; (c) superposition of flood wave peaks of main river and

its tributaries; (d) changes in channel and floodplain capacity – among

other reasons, because of construction of bank protection structures and protection dams.

Change in runoff of 1980-2010 relative to 1950-1979

Runoff decreasing in general Higher decrease in Hai River and Yellow River

Regional flood and drought hazards will probably increase The pattern of south-flood and north-drought will likely be

aggravated

Theme VI: Sediment Disasters and Mass Movements - Dr Tai-Hoon Kim (ROK)

17

Develop the Integrated Management Platform on sediment disasters – Connecting with system, policies and international

cooperation Three perspectives

– Issuance of warning – Improvement in capacity – Optimization of disseminating information

Issuance of warning Collect, review, and develop assessment tools Invent warning technologies based on adaptive

concepts Generate risk map

Guidance materials for implementation of risk management tools for identification, reduction, and evacuation

Identify the disasters
