Landsat's shortwave infrared (SWIR) band measures reduced moisture content in soil and vegetation. When combined with its near-infrared (NIR) band, which helps reveal actively growing vegetation, Landsat produces highly accurate images and maps of burned areas.

This March 2017 Landsat 8 image shows massive burned scars in Kansas and Oklahoma. More than 730,000 acres of farm and ranchland were scorched by wind-driven wildfires that began March 6 and were finally extinguished on March 22.

Pre- and post-fire images acquired with shortwave infrared (SWIR), near infrared (NIR), and red bands on Landsat 8’s Operational Land Imager sensor reveal a significant, 14,442-acre burn scar within the park’s high country. The burn scar appears red in the June 23 image.

This public-supply well taps groundwater in the High Plains aquifer in Texas. The strontium concentration in the sample from this well was 4,630 micrograms per liter, exceeding the health-based screening level of 4,000 micrograms per liter.

Heavy rains that began falling during Memorial Day weekend in late May 2016 pushed the Brazos River, 30 miles southwest of Houston, Texas, toward a near-record flooding stage that hasn’t been seen since 1913, according to the National Weather Service (NWS).

Currently, most of the streamflow equipment is located on a streambank or bridge. Large structures are no longer needed at most streamgage locations. Today, streamgage equipment can be contained in small metal shelters that are located on streambanks or bridges.
