The two remaining species are endemic to Atlantic slope rivers and include P. metallicus, ranging from the Ochlocknee River to the St . Johnsand Hillsborough rivers of peninsular Florida, and P. stonei with its northern distributional limit in the lower reaches of the Pee Dee River, South Carolina, to as far south as the Satilla River in southern Georgia.
For instance, the meandering length of a gently sloping river between source and mouth approaches, on average, pi times its straight-line distance.
Earthquake-induced landslides are of many different types and occur in virtually all geologic environments from steep and high glaciated rock slopes to gently sloping river flood plains and coastal areas underlain by soft sediment.
When I close my eyes, I can still picture the magnificent views of mountain slopes, river shorelines, and emerald trees of Katahdin Woods and Waters.
It is also a hardscrabble place where people struggle over what little level or arable ground there is, eking out a subsistence on the steep slopes, river banks and denuded hilltops called "balds". "No covered bridges," said Hugh Koontz, editor of the weekly News Record.
If the terrain permits, such as on a sloping river bank, several "shadoofs" can be used to lift water in stages through a greater height than is possible with one.
The PL domain is the westernmost and is characterized by meandering rivers with relatively low surface slope and river gradient, but high river sinuosity.
Thus, as uplift creates higher relief and steeper slopes, rivers achieve greater power for erosion.
As this falls on generally less permeable and steeper slopes, rivers rise and flow faster downstream.
The higher frequency of such events in the past 20 years has created cumulative impacts that have profoundly affected slopes, rivers and lakes on Banks Island.
