Remote Sensing for Flood and Volcano Monitoring

Explore the use of sensor web technology for flood and volcano detection and monitoring utilizing data from Dartmouth Flood Observatory and University of Hawaii. Learn how remote sensing aids in assessing surface water conditions and detecting volcanic activity. Enhance your understanding of flood warnings, flood hazard reduction, and volcanic eruption detection through orbital remote sensing techniques.

  1. Flood Sensorweb Uses Dartmouth Flood Observatory QUIKScat Global Flood Atlas: B. Brakenridge, Anderson, Ngiem, Caquard, et al., “Flood Warnings, Flood Disaster Assessments, and Flood Hazard Reduction: The Roles of Orbital Remote Sensing,” Proc 30th Intl Symp on Remote Sensing of the Environment, Honolulu, HI, Nov 10-14, 2003

  2. Floods - Detection Dartmouth-Flood Observatory QuikSCAT • The DFO in collaboration with JPL/QuikSCAT processes QuikSCAT Scatterometer data to assess surface water conditions. • VV/HH ratio is used to assess surface water properties of the areas in 0.25 lat/lon degree bins • The 7 day running mean is used to dampen effects of short-duration rainfall over urban areas. • This data is then compared to the seasonal (90 day) average of the previous year to screen out wetlands.

  3. Flood alerts are then used to retask EO-1. EO-1 Hyperion Image Brahmaputra Aug 6, 2003 MODIS Image Brahmaputra, India Aug 6, 2003 250M resolution (10M ALI Pan band possible) 30M resolution

  4. Impact Higher resolution data is acquired of: • key locations (pre-determined satellite gauging reaches) and • times (active flooding regions) With the end result of improved flood science.

  5. Status - Floods • September, October 2003 - Several demonstrations performed to track flooding in the Brahmaputra River basin, India • December 2003 – continued demonstrations to track Yellow River, China
