Im sorry I mean Tr66 Breach Hydrograph. Flowrate vs time data.

ok. I guess i can set multiplier on the principle to zero also or just strip it. I have a TR 60 breach routing i want to input. Is hydrocad using the same t and q formulas. Cant i just link my outflow data directly and bypass my subcatchment runoff for the original routing. I am trying to get to...

Ok. I think i got it. On Breaches: The help info for MODELING A DAM BREAK says that i should also include any other normal outlet structures that will continue to function.The primary outlet will be insignificant for my breach which will begin at the crest esw elevation. Do i strip it out of...

Ok Now i tried v/trap and now the notch angle can't be less than 20 degress.

That is correct. Custom weir/orific. I didn't know i had another choice?

Trapezoidal. 275 ft weir crest width at 0 head. 3033 ft width at 13.6 ft head

Did that- still won't let me.

It still won't let me go over 999.99. ? What am i doing wrong?

Did i tell you that "you da man". Thanks i am going to give it a try.

why does hydrocad restrict you to a 999.99ft weir width and how do you get around it? I am trying to route a breach that flows thru a box culvert and the roadway above will act as a trapezoidal weir but the overall with is much larger than 999.99 ft. How do i get around this or do i use another...

Thanks DamEng1- that closely matches my dams2 run.

need help modeling a broadcrested trapezoidal weir typical in dam emergency spillway designs. I use to run Dams2 for these and checked a hydrocad run against and old design. Upon comparison, i realized the emergency spillway calcs are not accounting for my sideslopes along centerline of the dam...
