• Dark red: > 10 yr flood (severe flood).
• Medium red: Between 5 and 10 yr flood (at level 4 or higher, major flood)
• Light red: Between 1.5 and 5 yr flood (Between Level 3 and 4, moderate flood).
• Light blue: ~1.5 yr recurrence interval flood (~Level 3, bankful to minor flood). Along many rivers, this is the bankfull discharge.
• Blue: surface water in current MODIS 14 day composite.

Supported by NASA Earth Science Applied Sciences grant NNX14AQ44G, 2014-2017, "Near Real Time Flood Inundation Prediction and Mapping For the World Food Program, GeoSUR, and US AID/OFDA".

Microwave data for River Watch are from the Japanese Space Agency and NASA (AMSR-E, AMSR-2, TRMM, and GPM sensors). Data are initially processed by the Global Flood Detection and Alert System, GDACS, European Commission's Joint Research Center, Ispra, Italy. Optical flood mapping data is primarily from the two NASA MODIS sensors and, for current conditions, from the MODIS NRT processor at NASA Goddard Space Flight Center, USA.

For vectorization of the Geotif (RGB): Blue, 48,117,255; Light blue, 208,240,255; Light red, 255,208,255, Medium red, 255,176,255, Dark red, 255,128,192.
