  1. Meteorological and Hydrologic Cooperation within APEC:“Today’s Challenges,Tomorrow’s Opportunities” January 12, 2001 Reducing Economic Losses From Floods and Droughts by Curtis B. Barrett NWS/IA

  2. World Water Crisis • By 2010 over 50% of global runoff claimed • World population will increase to 10 billion by 2050 • Water use competition is intensifying between Agriculture, domestic, industrial and energy • Transboundry competition for water threatens international stability (About 50% of all river basins are transboundry and involve 85% of worlds freshwater) • Polluted water, water shortages, and unsanitary conditions kill 12 million people per year • Economic losses from weather related disasters have reached a record high- $92billion in 1998.

  4. Total Insured and Uninsured Losses from Weather related Natural Disasters1980-1998 Figure 1

  5. Why a Water Crisis ? Population of the World continues to increase rapidly Water Supply on the planet is limited People encroach in floodplains and coastal areas Extreme meteorological and hydrological events are Occurring due to climate change Water pollution contamination is escalating

  6. Hydrometeorological DataSources • SNOTEL - High Elevation Snow Measurements • Volunteer Observers • Synoptic Surface Observation Network (ASOS) (Meteorological Data) • Automated Flood Warning Systems • GOES Satellite Data Collection Platforms • Limited Area Remote Collector Streamgages • Satellite Rainfall Estimates • NEXRAD Radar Derived Rainfall Estimates • IFLOWS-Interactive Flood Observing and Warning System

  7. Detecting and Predicting River and Weather Hazards • Meteorological • Satellites • Radar • Automated Surface Observer Platforms • Mesoscale Numerical Prediction Models • General Circulation Models • Climate Prediction Models
