The flow rate can be calculated for a rectangular channel with the equation:

where:

Q is the flow rate in cubic meters per second $[$m$^3/$s$]$

h is the height of water in meters $[$m$]$

b is the width of the channel in meters $[$m$]$

V is the velocity of the of the water in meters per second $[$m$/$s$]$

Then sort the table by flow rates $($in increasing order$)$ and save the sorted table as the new table StreamSorted. Make sure you are sorting the entire table and not just the column with flow rates.
