Description Usage Format Details
Volume lookup table constructed from RRE bathymetry. Structured as:
dist
distance along the thalweg marking the edge of each zone
furthest from the mouth, e.g. dist = 100
identifies the region
spanning 0 meters and 100 meters along the thalweg.
elev
elevation marking the the top of the depth increment,
i.e. elev = 0.1
identifies the region spanning 0 and 0.1 meters
elevation.
count
the total number of cells contained within each zone
and vertical increment.

A data frame with 3 variables
The volume lookup table was generated from the RRE bathymetry DEM
and zone delineations based on a manual trace of the river thaleweg. The
volume cells are defined as having a length of 0.3048 meters (1 foot),
width of 0.3048 meters, and height of 0.1 meters (cell volume of
0.009290304 cubic meters). Zones are
delineated in 100-meter increments along the thalweg, and each zone is
divided in the vertical into 0.1-meter increments from a minimum elevation
of -15.8 meters to a maximum elevation of 2.6 meters. The lookup table
lists the count of volume elements in each vertical increment in each
zone, i.e. each row lists the number of elements between river distances
d
and d - 100
and between depths z
and
z - 0.1
.
