This site from the Hydrologic Information Center of the National Weather Service discusses the flood risk in the United States. Maps and satellite images support the text. The site also provides information about snow levels, stream flow, soil conditions, forecasts and outlooks.

Southeast of San Antonio, Texas, rivers that were barely discernible in satellite imagery acquired in this late June 2002 by Terra MODIS stand out clearly in the congruent Aqua MODIS image from July 24, 2002. Heavy rains during the first week of July brought as much as 2 feet of rain to some places in southeastern Texas, resulting in massive flooding of three major river systems along the Gulf of Mexico. Please note that this story is in relation to the Flooding in Southeast Texas story and are match-framed for dissolves in post production.

Historical images on a map of California show disasters--flood, earthquake, fire, and disasease--throughout the state.

In its first day of operations, June 24, 2002, Aqua-MODIS observed significant Earth events occurring all over the globe. As Super Typhoon Chataan was rapidly approaching Japan, there was severe flooding in southeast Texas and a vast, thick pall of smoke from Canadian wildfires blanketed almost the entire U.S. East Coast. MODIS collected and beamed to Earth these images in very near real-time.

The three river scenes shown here are from central Missouri near Gasconade, Rocheport, and the confluence of the Grand River. The first in each pair was in September, 1992, the second in September of 1993. Notice the farmland in the river flood plain. The data uses Landsat TM bands 5, 4, and 2 mapped to red, green, and blue respectively. Bare soil and plowed land appears red, vegetation (which reflects very strongly in the near infrared) appears green, and water is dark blue. The perspective in each of these images is looking approximately westward, which is upstream.

At the completion of this lesson you will be able to express regret for actions you failed to take in the past. What type of action will you be able to take against floods and how do you contact the municipality to obtain information on preventive measures?

Like Earth, Mars has valleys that seem to be caused by a flowing fluid, presumably water. One can see dendritic drainage patterns as well as flood channels on the Martian surface. This module focuses on whether the channels observed on Mars are evidence of great floods and, if so, on how Pathfinder helps scientists to use the debris from such floods to obtain information about four billion years of Martian geologic history.

This activity helps students learn how to find, interpret, and describe weather data. Students learn also about drought, flooding, wind and dust storms, hurricanes, and lightning, as well as the Tropical Rainfall Measuring Mission (TRMM) satellite -- the information it provides and why that information is important.

This website is part of the Mississippi History Now web newspaper. The feature story discusses engineering of river control in the Mississippi. Topics discussed in the story include the need for river control, efforts to control the river, the 1927 flood and impacts on the environment. The story includes suggested readings and a lesson plan associated with the story.
