Representative River Watch Information (clickable dots above)
At selected locations, a time series of satellite microwave-based daily river discharge measurements are available from the Flood Observatory. See River Watch Global Display for more information. A sample from Site 30 is shown below.
Explanation
Map Symbology:
Red, flooding. Surface water is larger in extent than the Blue reference water. Blue, Average Annual High Water. Magenta, Surface water is present but within limits of the reference water. Dark Blue, Winter surface water. Light Blue. Previously flooded areas.Source Data:
MODIS water mapping information at a spatial resolution of 250 m is from NASA's Terra and Aqua satellites via an automated water classifier. The Flood Observatory accumulates daily files from a special processor at the NASA GSFC over 14 days (running forward, updated each day). This red and magenta layer provides nearly complete geographic coverage even under cloudy conditions. New artificial reservoirs built since 2000 also appear as magenta.Interpreting These Maps:
Floods in hilly or mountainous regions are difficult remote sensing targets and not always observable. Also, cloud cover or heavy vegetation may restrict the ability to capture flood inundation everywhere. The maps may not illustrate all areas of flooding, and cloud and terrain shadows may be misclassified and falsely mapped as flood water. Current surface water includes both magenta and red colors; red areas are water extended beyond the normal maximum annual extent. Finally, due to the relatively coarse resolution of MODIS 250 m bands, some areas mapped as flooded may include smaller parcels of dry land.Suggested citation:
