Input The "Input" menu choice is used to enter data in a new R2CROSS.WK4 worksheet or to correct/edit data in an existing worksheet. As depicted in Table 3, the <ENTER> key is used for the initial entry of the information contained within the "Location Information" . "Supplemental Data", and "Channel Profile Data" sections of the field form. The arrow keys are used for the initial entry of the "Discharge/Cross Section Notes" within the "Input Data" table, The arrow keys are also used for all subsequent editing of data, This ,procedure ensures that the cursor is always located within the appropriate cell of the worksheet during the initial entry of the "Location Information", "Supplemental data" and "Channel Profile Data" (not always a one cell movement) and also allows the greatest flexibility in the initial entry of the discharge notes and subsequent editing of data. Entering data in a new file To enter data in a new file: ], Select the "Input" menu choice. 2. Count the number of data points (cell verticals) collected across the stream channel. Key-in that number and press <ENTER>, R2CROSS automatically sizes the worksheet to the proper number of discharge cells, 3, Once the worksheet has been sized, the macro prompts for the entry of a -24- 4, "Stream Name", Key-in the "Stream Name" and press the <ENTER> key to complete the data entry. Follow this same procedure for all of the information contained within the "Location Information ", "Supplemental Data", and "Channel Profile Data" data entry cells. The final use of the <ENTER> key occurs after the entry of a stream "Slope". The cursor then moves to the upper left comer of the "Input Data" table (cell C50), Use the arrow keys to enter all channel geometry and stream velocity data within the "Input Data" table. Key-in the horizontal distance from the zero stake to the cell vertical in the "Dist" column, vertical distance from the suspended tape to the channel bottom in the "Vert Depth" column. water depth in the "Water Depth" column. and water velocity in the "Vel" column for each cell. in the cross section, Use the "Feature" column (Column B) to indicate the horizontal locations of the cross section stakes (S). grasslines ( G). waterlines (W), and other features such as rocks (R), etc. Finally, enter a ";" in the appropriate cell of Column A to indicate the location of the grassline/streambank intersection on each streambank, R2CROSS uses the grass line locations to determine bankfull wetted perimeter and top width. These grassline locations are integral to the development of biologic instream flow recommendations in Colorado. The R2CROSS macro will not proceed until the grassline/streambank intersection on each streambank has been depicted with a "I" in Column A of the worksheet,
