i’m trying to make dam break analysis with 2D only flow area but i got the following error.
***** Error! Extrapolated beyond Storage VOL vs EL curve *****
looking forward for any suggestions
This RAS message relates to a storage area element. If your reservoir (storage area) is described by a storage-elevation relation; this data needs to be provided using the geometric data editor. But, if the entire region is modeled as 2D, this might be a false message.
actually i had defined the elevation-storage relation to my storage area up to the crest level. I took the bald eagle creek dam break study of HECRAS as an example except that i used only weir option without gates. But what i got as a result is something completely wrong.
