Question

What is the vertical drop, or elevation drop, of a stream with headwaters at 1000 m and its mouth at 328 ft?

Answer 1

To determine the vertical drop of a stream with headwaters at 1000m and mouth at 328ft, the two measurements must first be converted into the same unit of measurement. 1000m is 3280.84ft. The drop would be 3280.84 feet minus 328 feet which would equal 2952.84 feet. When converted back to meters, the elevation drop of the stream is found to be 900 meters.
