Proposal to 2007 Annual Regional Call for
Proposals (ARCP) , APN
With in the context of the APN support the flood research
project will address following specific objectives:
1. Converting observations and data, both through space borne
platforms and data integration initiatives, to usable information forflood reduction.

2. Improvement of quantitative forecasts for coupled precipitation flood-forecasting systems.

3. Facilitate risk assessment through the provision of scenariosand data for exposure estimation.
 It is essential to enhance and utilize regional cooperation to achievethese objectives using the resources and knowledge available atvarious specialized institutions. Training programs on the use of tools
and data will form the basis for to capacity development activities.

 Introduction of activities of Flood Monitoring WG

at the Sentinel Asia Project organized by AsiaPacific Region Space Agency Forum (APRSAF)
and International Flood Network (IFNet) Any linkage and mutual cooperation withSentinel-Asia Flood Monitoring WG and IFNetGFAS project should be enhanced and promoted.

Development ofIntegrated Flood Analysis System (IFAS)
A computer software package specifically for flood runoff
analyses with GUI using ground-based and satellite-based
rainfall data
Being developed by a joint research (FY2005-2007)
at ICHARM/PWRI,
Infrastructure Development Institute (IDI/IF-Net),and nine major civil-engineering consulting companies

Satellite rainfall

Runoff analysis
Global GIS data

Utilization of satellite-based rainfall

Internet

Ground-based rainfall data

Data at different times.

Automatic Estimate of Parameters
as a first approximationby use of globally available GIS datasets

automatically

Use global GIS data such as USGS-GTOPO30, GLCC, etc.

Preliminary discussions on the target of 2nd phase of Flood
Monitoring WG
at 3rd WG in Manila, Philippines

1. Global satellite-based hourly/10km-grid rainfall mapping
1.

JAXA and ICHARM/PWRI are planning to jointly develop the prototype
system based on the JST-CREST GSMaP led by Prof. Okamoto(Osaka Prefectural Univ.); (Start before the end of March 2009)

2. Next-phase GFAS
1.

2.

3.

Flood forecasting and inundation mapping using the above satellitebased rainfall products using IFAS (Integrated Flood Analysis System,ICHARM) (Start before the end of March 2010)
Select few Pilot demonstration river watersheds with the participationof Sentinel Asia Flood Working Group (Start: Before the end of March2009)
Parallel exploration of assimilating river-and rain-gauge observation

3. DEM: Create DEM of flood prone areas (Pilot Study) bymembers using ALOS data and validate (Start: Before the end ofMarch 2009)

4. Sharing the local studies and achievements through theSentinel Asia Portal - member countries/organizations

What is IFNet ?
1. Beginning
IFNet was set up as an open network everyone can join on theflood day of the 3rd World Water Forum in Kyoto, March 2003

Background: Rising trend of flood damages
 View of flood issues as locally limited problems
 Few networks then dedicated to flood issues
 Necessity to give priority to flood issues

2. Objectives
To contribute to flood disaster reduction by: Sharing knowledge and lessons learned,
 Promoting good practices, Raising awareness of flood issues and flood risk
among policy makers and the general public.

3. Membership IFNet is an open,open, free of charge,charge, network to everyone.
 Advantage:
Advantage: Opportunity to present activities in forums etc.
CustomCustom-made GFAS information (plan)

4. Ongoing projects
 IFNet Action Report- Good practices, lessons learned, etc.
 Global Flood Alert System (GFAS)- Flood early warning, evacuation, etc.
 Information Exchange/Dissemination- Participation in forum, training programme,
list of worst floods,floods, newsletters, etc.
