INPUT DATA:

[Sample input]     [Rationale]     [Procedure]     [Features]

Stream or river (optional):

Select:        U.S. Customary or SI units [Default: U.S. Customary Units].

 1. Discharge Q [cfs] (m3/s):      qdin   2. Mean velocity u [fps] (m/s):      vein   3. Average depth d [ft] (m):      dein   4. Width w [ft] (m):      wdin   5. Flow area A = 0   6. Water temperature t [oF] (oC):      tein   7. Kinematic viscosity ν = 0.00000000 8. Diameter D65 [ft] (mm):      d65in   9. Diameter D35 [ft] (mm):      d35in   10. Measured concentration C [ppm] (ppm):      coin   11. Sampled suspended load Qsm = 0   12. Vertical distance not sampled dn [ft] (m):      dnin   13. Mean water depth at sampled verticals ds [ft] (m):      dsin

14. Number of size fractions:       Normal has 9 size fractions (1 fine and 8 coarse); Long has 10 size fractions (2 fine and 8 coarse) [Default: Normal].

15. Enter fraction of bed material in each size range (make sure it is 9 values for Normal; 10 values for Long) (separate each value with a comma; maximum character length is 100 characters).

ib:

16. Enter percentage of suspended material in each size range (make sure it is 9 values for Normal; 10 values for Long) (separate each value with a comma; maximum character length is 100 characters).

Q's:

17. Z' mode of computation:       See No. 6 in Features [Default: USBR (1955)].
