Streamflow Analysis
1. Select your year which begins on October 1st and ends on September 30th
copy and paste it into a new workbook. So if you have 1968 you begin Oct 1,
1967 and end Sept. 30 1968.
2. Insert three blank rows at top and copy and paste three top rows from
discharge worksheet.
3. Determine the mean, standard deviation for each of the five columns of data.
Use Insert function than select average (mean), stdev (standard deviation).
For each column data should be in rows 4 through 368.
4. Determine the correlation coefficient between every combination of each
column b:d:f:h:j. Calculate these all at once by entering the data column
coordinates
5. Calculate the flow per unit area for each column. =b4/area etc. For all four
columns. Areas are in row 2. Rename each column for river.
6. Graph the resulting four columns in a line graph. Removing unneeded
columns. By clicking the remove function under series in step two. Make
sure values of each line are rows 4 to 368, and same for x axis values which
are the dates a4:a368
7. Add linear trend lines for each river, by right clicking on data line.
8. Turn in statistics, and graph, not raw data, and interpretation
about the role of glaciers in altering the timing of glacier runoff in each basin.
Use the linear trend lines to note important changes in timing and magnitude of
runoff. Note when glacier flow is noticeably higher than for non-glaciers and
vice versa. Note percent glaciation is in row 3.
