I am thinking to make a lidded cross section since I have a cross section in upstream and down stream and I will get few cross section with in the culvert with interpolation so I can get the real opening of the culvert.
just wondering will it give me the correct water flow level in steady flow analysis?

[sthsajan]

Is there any other way than lidded cross section ?
like can we make fish baffle by adding inline structure?

[sthsajan]

my culvert opening is just 6 feet so I wanna restrict my flow with in 6 foot in the lidded cross section so the water level can raise. it looks like I have wide opening in lidded cross section since I do not have the proposed contour in that section I am creating the lidded cross section in the existing ground but wanna restrict the flow with in 6 foot of the opening but the opening looks more than 10 ft

I made a series of culvert with lidded cross section in between two culvert.
This culvert is proposed to extend the 25 ft in upstream so I do not have proposed contour or cross section of 25 ft upstream side
I created a culvert I have a issue regarding the cross section how water flow in culvert and lidded cross section. is there any way that I can control water flow only in the perimeter of lidded cross section same like in culvert so that that I can get the exact water elevation in the lidded cross section. my water is flowing outside of lidded cross section

I created one with the hec ras with lidded cross section
it looks like this but I got a problem that my 100 yr energy grade line over top the culvert
could you please get some help?order=”0″/>

could you help me how to adjust my energy grade line and how can I fix the wall of lidded cross section
do I need to add the influence area flow in the lidded cross section

I have a culvert length of 137 ft
upstream culvert station 544.19 with slope 4.5% other one is change of slope st 519.19 with slope 6.62% and downstream culvert at 407.19. where should I begin my culvert at 544.19 or 519.19 or else and where should I add lid I am so confuse
which station should I add lid can I fix my invert elevation of the lid

[sthsajan]

Do I need to make two different culvert and connect them for 2 different slope or can I make one culvert with variable slope?
I tried to connect two station of different slope
I have st 544.19 to start my culvert with 4.5% slope and other 6.62% slope begins from st 519.19. I have upstream station at 550 now
I created first culvert at upstream 544.19 with upstream 550 and tried to create one more culvert at downstream of slope change at 519.19 but I am confuse what upstream distance do I need to enter (as 519.19-519.9=0 or 550-519.19=30.81 and same as width what do u need to enter. I am tried to connect two culvert for my different slope.
I tried to make 2 culvert with different slope and try to connect but the second culvert in downstream that I wanna tie with first one I am confuse in upstream distance do I need to put zero
my different in slope distance is 25ft (544.19-519.19) and remaining length is 112 ft
could you help me ?
or can I do lid in cross sextion and make different slope so that one culvert will solve my issue?
