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 bottom slope So (m/m) [ft/ft] :    

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 yd (m) [ft] [If left blank, program will use critical depth]:    

To calculate critical depth, the program requires the following hydraulic and geometric data for the upstream channel:
[Leave any 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):    


Discharge Q =                Bottom width B =                Side slope z =  

Manning's n =                Bottom slope So =  

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

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

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


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