Using examples from the Willamette Valley of Oregon, terroir of the region will be discussed because it is strongly influenced by the bedrock geology and soils. Using LIDAR they can see where the Missoula flood scrapped some areas to bedrock and deposited gravel beds in others. Maryland is part of six physiographic provinces (shown in the figure below). In the following we report the results of a simple test of (4) using topographic maps from the Coast Ranges of Oregon, USA, which appear to support this technique, yielding a ratio of m/n equal to 1.0 for low gradient channels and greater than 1.0 for slopes steeper than 0.2 where debris flows dominate erosion.
