Asia Flood Network—A USAID Program for Flood Mitigation and Preparedness in
Asia
• Asia Flood Network Program Objective
– Identify and fill gaps in end-to-end flood forecasting and early warning to mitigate adverse impacts of extreme hydrometeorological events
• Benefit– Reduce vulnerability to
hydrometeorological hazards in Asia
Asia Flood Network—A Program for Flood Mitigation and Preparedness in Asia
• Develop partnerships between hydrometeorological entities in Asia and US counterparts, such as:
– US Agency for International Development Office of Foreign Disaster Assistance (OFDA)
– US Geological Survey (USGS)
– National Oceanic and Atmospheric Administration (NOAA)
• Pre-program assistance to the Mekong River Commission (MRC) began in 2001 in the form of daily rainfall estimation and forecast
• Process– Asia Flood Network was
launched in 2003 by OFDA, with technical support from NOAA and USGS
– Initial dialogue is centered on the Mekong River basin and assisting MRC’s recently adopted Flood Management Program
– Other activities include the Ganges-Brahmaputra-Meghna (GBM) Basin and other basins in Asia
Asia Flood Network—A Program for Asian Flood Mitigation and Preparedness
• USGS and NOAA automated hydrometeorological data-collection
• GOES (and other meteorological) satellites for real-time data relay
• NOAA National Weather Service River Forecast System (NWSRFS)
• USGS GeoSpational Forecast Model
• Tropical Rainfall Measuring Mission
• Distribution of data and warnings

National Hydrologic Information System Products
USGS Hydrologic Information System is demand driven through cooperative funding agreements with >1,600 State, county and local agencies and other Federal Agencies
National Hydrologic Information System—Demand Driven
Flood Warning System, a Special-Case Hydrologic Information System
Data Communication
Forecast and Warning Dissemination
Planning and Coordination

Flash-Flood Warning Systems
Community based protection via real-time Alert Systems
Alert systems:• Community based and operated• Small geographical areas• Rapid response• More monitoring and warning than
forecasting• Provide warnings to the public and
emergency response organizationsInformation at

NWS Large River Forecasting
Multi-day river forecasts are prepared every six hours for 4,000 forecast points on large rivers from 13 River Forecast Centers, using a common NWS River Forecast System (NWSRFS)
NWSRFS contains >40 hydrologic and hydraulic models, includes Xinanjiang Soil Moisture Accounting Model
NWS Large River Forecasting
Products include short-term and ensemble forecasts
The forecasting system continues to be modernized and supported under the Advanced Hydrologic Prediction Service Program
USGS GeoSFM
USGS GeoSFM
GeoSFM is being validated in Distributed Model Intercomparison Project (DMIP) basins with good results, using a standard NOAA-provided data set from a data-rich area in the United States
Integration of USGS-NOAA Tools
USGS and NOAA are integrating GeoSFM into the NWSRFS to provide:
• OFDA and potential Asian partners with a new tool for river and flood forecasting, that can be implemented promptly
• NOAA with a spatially based interface to NWSRFS• USGS with a system in which to operate GeoSFM
