INPUT DATA:

Select:       [Choose S.I. Units or U.S. Customary units

Enter discharge Q (m3/s) [cfs]:              Enter bottom width B (m) [ft]:              Enter side slope z (z H:1 V):    

Enter Manning's n:    

Enter number of computational intervals n (suggested range 50-200) [If left blank, a default value of 100 will be used]:    

Enter number of tabular output intervals m (suggested range 10-50) [If left blank, a default value of 10 will be used]:    

Enter flow depth at the upstream boundary yu (m) [ft] [If entered, program will compare with normal depth; if left blank, program will use normal depth]:    

To calculate normal depth at the upstream boundary, the program requires the following hydraulic and geometric data for the upstream channel:
[Make sure that the u/s flow is supercritical, i.e., that bottom slope So,u/s >>  0. This may require trial and error. Leave any other box blank if the value is the same as the corresponding value entered above].

Enter u/s discharge Qu/s (m3/s) [cfs]:              Enter u/s bottom width Bu/s (m) [ft]:              Enter u/s size slope zu/s (z H:1 V):    

Enter Manning's nu/s:              Enter u/s bottom slope So,u/s (m/m) [ft/ft] [do not leave blank]:    

ECHO OF INPUT:

Discharge Q =                Bottom width B =                Side slope z =  

Manning's n =   

Number of computational intervals n =                Number of tabular output intervals m =   

Flow depth at the upstream boundary   yn =  0 [ yn was calculated by default ]

Discharge Qu/s =                Bottom width Bu/s =                Side slope zu/s =    

Manning's nu/s =                Bottom slope So,u/s =    

OUTPUT:

Computational depth interval Δy =   0                     Tabular output depth interval (Δy)t =   0

Froude number of upstream flow Fn,u/s =  0 

Critical depth yc =  0                     Critical slope Sc =  0
