Results
Data for all cross sections are summarized and presented in Appendix Tables 1 to
6. Data for strata 12, 3, and 4 are given in Appendix 1 to 4, respectively. Strata 6 and 8,
are in Appendix 5 and 6, respectively. The data in each of these appendices are grouped
by riffles (A), runs (B), pools (C), and eddies (D). Within each habitat groups are the
results of inflection points identification (1), and the data and curves for the relationships
between flow and the six variables of interest, i.e. percent wetted perimeter (2); wetted
stream width (3); average depth (4); stage (5); width/depth ratio (6); and velocity (7)
Table 1 presents the strata, clusters, the date and number of cross sections for this
study. In general, the flows determined in the field were somewhat higher than reported
for the Maybell gage in Strata 6.
