The limitations of outcrop must be borne in mind when using these data to interpret paleoslope, as it is common for ripples in turbidite successions to record directions that differ from the local slope (e.

107[degrees]) from a single locality in the Hampton Formation, northeastern Tennessee, and interpreted this to indicate that Chilhowee currents moved primarily down the regional paleoslope to the southeast.
With this paleoslope model it was possible to estimate the waterdepth range of many species of benthic foraminifers in the Late Cretaceous Basque-Cantabrian Basin.
Paleoslope is obtained by simplifying the equations governing fluid flow to the case of a steady, horizontally uniform flow in a natural channel, where friction on the walls of the channel is negligible compared to that on the channel bottom.
Reconstructing the flow conditions that resulted in the deposits of the Sharon Formation was accomplished by determining the dimensions of channels, the grain sizes transported by the streams, and the paleoslopes.
Paleoslopes were calculated from solving these equations for slope when the transport stage was set to 1 (initial motion), using paleohydraulic data for bankfull depth, and grain size data (Mohrig 1987; Evans 1991).
Paleoslopes were calculated using the methodology discussed previously.
