HEC RAS 2D:Culvert model

[@GeromeVanWyk]

Good Video Wanted to know is there a reason why the culvert that is introduce in my model does not convey the water instead the water flow pass it

[@zainabbutt3726]

just wanted to ask do we have to import subbasins which were generated in hechms, in hecras and then do we need to define boundary condition for each subbasin separately or do we have to create a single 2d flow area perimeter for all the subbasins as whole, for 2D flood modeling? as we'll be using outputs from hechms which were generated for each subbasin

I tried following your steps but got the following error message: ERROR with Connection(s) The SA 2D Connection has a culvert lower than the cell it is connected to. Do you have any idea what might be causing this? According to the warning message I'm placing my culvert under the terrain level, although I need to place it under since my terrain acts as the embankment area. Hopefully my explanation was helpful. Thanks for the tutorial!

I've highlighted this in 9:57 part of this Video

Esta mal agregada la alcantarilla. El flujo pasa por interpolación de las celdas y no por que realemente exista una alcantarilla... suele pasar esto mismo incluso sin la alcantarilla... mira mejor el siguiente video de los creadores de HecRas. kzbin.info/www/bejne/nJ-to42Mh9x2odUsi=jxHgadetsXG9ZcZ6

please make a video on scour depth prediction using hecras model

[@JALAJDARPAN]

okay

[@peterokitoi7757]

How would someone know how many culverts you would need for water to flow properly without overtopping ?

[@JALAJDARPAN]

it's based on expirence and site inspection you can tentatively assign number of culvert openings

[@rajanhumagai]

Can you assist with bridge height determining

[@JALAJDARPAN]

Yes okay
