<br />Iron Creek Example
<br />
<br />Figure E depicts an actual set of
<br />R2CROSS field data collected on Iron Creek, a
<br />tributary to the Fraser,River in Grand County,
<br />Colorado, Assuming that the R2CROSS macro
<br />has been installed and initiated as described
<br />above, highlight the "Printers" menu choice and
<br />select either the LaserJet or Dot Matrix menu
<br />choice, Other printer-types may require a
<br />customized setup (consult your Lotus 1-2-3
<br />reference manual),
<br />In order to ensure that all subsequent
<br />data files are stored in the R2CROSS
<br />subdirectory, select the "Retrieve" menu choice,
<br />choose the "Path" suboption, key-in:
<br />c:\ R2CROSS
<br />and press <ENTER>,
<br />To initiate data entry, select the "Input"
<br />menu option, R2CROSS then prompts you to
<br />enter the number of data points collected in the
<br />stream cross section, Count the number of data
<br />points (Iron Creek has 34), key-in this number
<br />at the prompt, and prcss <ENTER>.
<br />Enter the remainder of the data within
<br />the "Location Information", "Supplemental
<br />Data", and "Channel Profile Data" sections of
<br />the R2CROSS macro. Use the <ENTER> key
<br />to complete each data entry and move the
<br />cursor tIuough each of the data input cells in
<br />sequential order, The final use of the
<br /><ENTER> key occurs after keying-in the
<br />stream "Slope",
<br />After entering the stream "Slope", use
<br />the arrow keys to enter all of the "Feature",
<br />"Dist", "Vert Depth", "Water Depth", and "Vel"
<br />data from the Input Data table of Figure E. The
<br />grasslines on each streambank represent a very
<br />important piece of information in the
<br />R2CROSS analysis, In the Iron Creek example,
<br />these grasslines occur at distances of 1,00 and
<br />11.00 feet. It is imperative that these grasslines
<br />be identified within R2CROSS by placing the
<br />number" 1" in the appropriate cell of Column A
<br />in the R2CROSS worksheet. This designation
<br />
<br />is so important that the R2CROSS macro will
<br />not proceed until the two grasslines have been
<br />specified, After entering all of the data within
<br />the Input Data table, including the two
<br />grasslines, simultaneously press "<Ctrl> G" to
<br />terminate the data entry routine and return to
<br />the main R2CROSS menu,
<br />Select the "Verify" option to print a
<br />"Proof Sheet" for comparison with Figure E. If
<br />data entry errors are found, return to the "Input"
<br />menu option and correct them. When editing
<br />data, use the arrow keys to move around the
<br />worksheet and correct mistakes. When all data
<br />entry errors have been corrected, exit the
<br />editing routine by pressing "<Ctrl> G", The
<br />data editing routine can be repeated until all
<br />data entry errors have been corrected,
<br />Once all data entry errors have been
<br />corrected, use the "Save" menu choice to store
<br />the input data file to the R2CROSS directory on
<br />the hard disk drive, Select the "New File"
<br />menu option, type an appropriate eight letter
<br />me name for the data set, and press <ENTER>.
<br />The file will automatically be saved with a
<br />,WK4 file extension, Caution: do not name
<br />the me "R2CROSS".
<br />Select the "Calculate" option and press
<br /><ENTER> to initiate staging table calculations
<br />and print the final output from R2CROSS,
<br />Verify that the printed output is identical to
<br />Figures F through],
<br />Select the "Graph" option to view the
<br />cross section plot. Press <ENTER> to exit the
<br />view and print the cross section plot.
<br />Exit the R2CROSS macro by selecting
<br />the "Quit" option. Answer "No" to the Lotus
<br />prompt to exit R2CROSS and remain in Lotus
<br />1-2-3,
<br />
<br />This general procedure can be followed
<br />to enter, edit, and analyze almost all R2CROSS
<br />datasets, To begin data entry on your own
<br />R2CROSS data set, select "Retrieve" a "New
<br />file" from the R2CROSS menu,
