Canyons: Wide Valleys and Small Streams

Geology
The landscape of the Earth contains many canyons and wide valleys that contain much smaller streams.
While evolutionists and old-earth geologists support the idea of uniform geologic processes that eroded the landscape over millions and billions of years, creationists have postulated that stream and river discharge in these valleys was much larger in the past during catastrophic events, such as sudden flooding events.
If discharge in these valleys was larger, then erosion rates would have been larger and the amount of sediment eroded and removed would have been larger. H.F. Garner describes dry channels, waterfall scars, and gravel bars observed around the world associated with streams that once had a much larger discharge but now exist in a primitive, relict form (1).
These larger stream and stream features are not forming today in contrast to the uniformitarian philosophy. The global flood described in the Book of Genesis and its receding floodwaters would have eroded these wide valleys very rapidly. As the receding floodwaters emptied into the oceans, the streams in these valleys would have been greatly reduced in size as is observed today.
