hii stefan,

my model is related to inland application that study how overflowing from rivers are inundating the floodplain.

hi,
how to model sink in mike 21 flexible mesh?

thanks

what should i do if i have multiple boundary conditions??

hi stefan,
yes, i agreed with that. but in MIKE 21 fm we can choose either bathymetry or mesh. i'm using the same bahymetry which i used for the MIKE 21. so the entire input for both MIKE 21 and MIKE 21 fm is same but result not getting the same.

thanks and regards

Hi,
i have done 2D flood modelling using bathymetry with MIKE 21. then i used the same bathymetry for 2D modelling with MIKE 21fm. but im getting completely different inundation pattern. why this is happening?
thanks in advance...

thank you stefan,
i had given my bathymetry data it self as the initial elevation. but for every grid value in bathymetry i increased value by 0.01m so the initial water depth will be 0.01m.

thanks again.

what value i have to choose as initial surface elevation?

i am modelling an area 50kmx50km in mike 21. my bathymetry file contains elevation from 3m to 53m. i choose land value as 60. no i have to create open boundary. for that i changed land value (60) to some elevation depending on the neighbor point's elevation. the problem is with initial surface elevation.

which toolbox you used exactly?
