Hi,

The area downstream my dam is completely flat. My main goal using BOSS DAMBRK is to get the hydrograph for different scenarios. My Range of parameters are close to Crest width =4000ft, breach width =150 to 650 ft. When i was defining the "real geometry of the downstream area" i was getting floating point errors, I defined my cross section downstream close to the "breach geometry" and know it is working. Is that a limitation of the program? Is there any other way I can approach this problem?

Thanks
