Initial capabilities to use a velocity parameter to define the scale of the Gamma distribution. Hongli will complete testing.

@h294liu -- returning to an old pull request. Can you provide an update on the progress of these developments?

I am so sorry for not following up on this work! Sure, I am happy to complete the test after submitting the pyviscous manuscript this week. Does this work?

Yes, all is perfect! Thanks so much Hongli!!!

I have tested and found that SUMMA run through these new codes without any problems. Yeah!

Test Setting Configurations

• Set subRouting as constVel in the "modelDecisions.txt" file.
• Add the following to "basinParamInfo.txt" file: routingVelocity | 1.00 | 0.1000 | 100.0000
  Note that the three numbers are the default, min, and max values of routingVelocity.

Test Results
The test domain is the Bow at Banff basin. The model includes 51 GRUs and runs for the year of 2008 (365 days). The model output is daily averageRoutedRunoff_mean.

Below is the model output comparison for one GRU (10 days).

• The black line is for the timeDlay method (old method).
• The other two lines are for the constVel method (newly added method).
• The red line uses flow velocity=100m/s, and the blue line uses flow velocity=0.1m/s.
