1993 Missouri River Flood Exercise
Summary
This exercise is done after a brief lecture/discussion on flooding and its effects, and after viewing the 55-minute PBS NOVA video "Flood!" which was filmed and produced during and after the 1993 Mississippi River flood.
Students are presented with several LANDSAT images of a portion of the Missouri River near Glasgow, Missouri, illustrating the valley before, during, and after the 1993 flood. Students are asked to identify and interpret features visible in the images, and to respond to questions about the flood based on both the images and their recall of what they observed from the NOVA video.

Learning Goals
Among the concepts students are expected to learn from this activity are the effects of severe flooding, the changes that occur in river systems as a result of severe flooding, impact on human activity due to flooding, and river dynamics. Students are asked to critically evaluate images of the effects of flooding, and to apply previously learned concepts of stream flow, sediment sorting, and stream erosion to images they have not seen before.
Context for Use
The exercise is used as a lab, part of a unit on stream processes in an introductory-level physical geology course. The exercise typically requires 30-45 minutes to complete. No special equipment is necessary to complete the exercise. It could be used as an in-class exercise, assigned as homework, or presented online.

Assessment
Students assessment is based on the quality of the responses to the questions provided in the exercise. The exercise could be assigned to individual students, or done as a paired or group exercise. Students are required to observe new data and interpret that data based on previously learned concepts.
