2. Stream Velocity Tutorial Start

3. These are readings from station 1. End

4. The rates of change can be adjusted. End

5. Now, let’s change the channel gradient from 0.55 to 0.70. End

6. Notice that the gradient of station 1 is the same as the value of channel gradient above. End

7. Now, let’s change the rate of change. End

8. From station 1 onwards, there is a constant decrease of gradient by 0.030 for stations 2 to 10. End

9. Let’s change the hydraulic radius of station 1 to 0.7 and the rate of change to 0.01. End

10. Notice the corresponding changes here. End

11. From station 1 onwards, there is a constant decrease of hydraulic radius by 0.010 for stations 2 to 10. End

12. Now, let’s change the channel roughness of station 1 and rate of change to 0.07 and 0.002 respectively. End

13. Here we have a new set of channel roughness readings. End

14. With Gradient With Gradient, Hydraulic Radius With Gradient, Hydraulic Radius and Channel Roughness With gradient, hydraulic radius and channel roughness, a set of velocities are calculated according to the formula End

15. These values show the percentage change of Gradient, Hydraulic Radius, Channel Roughness and Velocity. These readings show the percentage changes of gradient, hydraulic radius, channel roughness and velocity. End

16. Click on the Velocity graph tab, a plotted graph will be shown. End

17. This graph adjusts in accordance to the readings in channel gradient, hydraulic radius and channel roughness. End

18. Click on the Velocity tab to go back to the previous screen. End

19. That’s the end of this tutorial. End
