How to Model Pipe Flow in HEC-RAS 6.6
For the first time, HEC-RAS can model pipe flow networks thanks to the new beta Pipe Network feature in version 6.6! This video provides a step-by-step guide on setting up and running a pipe flow network simulation, from creating and attributing network data to running a stormwater simulation and visualizing results. This game-changing feature is a must-see for HEC-RAS and stormwater modeling professionals. Watch to discover powerful new possibilities for the future of hydraulic modeling!"

Creating a basic HEC-RAS 1D Floodplain Model
มุมมอง 6Kปีที่แล้ว
Learn how to create a basic 1-dimensional steady state HEC-RAS flow model in this straightforward tutorial. I cover the basic concepts and theory of the HEC-RAS step backwater calculations used by the program and show the practical steps to set up a simple floodplain model. I also demonstrate some ways you can review your results to see any obvious errors or warnings that may require revisions ...
HEC-RAS 2D Model Sensitivity
มุมมอง 1.5Kปีที่แล้ว
In this video, I explore the sensitivity of some of the HEC-RAS 2D model features and parameters. I'll look at a simple 2D model and test several variables for sensitivity. I'll evaluate the impact of cell size, use of breaklines, and evaluate the diffusion wave equation vs. the full momentum equation results.

Learn how to create and edit breaklines in a HEC-RAS 2D mesh.
When I import my infiltration data does it have to be a shapefile or can it be a raster format such as TIFF? I typically create my infiltration layer outputs as a TIFF.
Would you say HECRAS 6.6 is a viable and reliable alternative to software like PCSWMM?
Nice demo. Can you compare model results with pipes and without pipes to see how big the difference is? Thank you
This is fantastic. Great video. I'm a stormwater designer and work with both SWMM and HEC-RAS. The recent development in 2d modelling capabilities have really taken the type of open channel modelling we can achieve to another level. We investigate urban flooding issues which often involve both networks and open channels and on many occasions have utilized swmm outputs as inputs into our HEC-RAS modelling. However, now with these additional capabilities we should be able to get the best of both worlds. It will speed up our workflow and should also produce more accurate results.
I am about to take a course in PC SWMM with IHE, do you advise me to cancel the course as I am fully aware and skilled with Hec Ras? Waiting for your advice. Thank You
@@Aldoodgrgr Hi, youtube comments are probably not the best place to request such advice nor to give it. However, I would comment that although there is some cross-over in capabilities, SWMM and HEC-RAS are different software packages with generally different purposes. It is horses for courses meaning that for any given modelling exercise, you should use the most appropriate package for the type of system you are assessing and what information you have at hand. For instance, with these new capabilities, would I use HEC-RAS in place of SWMM for piped network analysis? Absolutely not, nor would I consider this to be a goal of the introduction of these capabilities. I have not yet myself had the opportunity to use the package, but one advantage would appear to be that it can provide some 2d capabilities in urban areas where piped networks are the predominant drainage system (which other SWMM packages also offer - though at a price). This doesn't mean you should use it instead of SWMM though. The benefit here is that this will allow HEC-RAS modelling to be complimented by SWMM modelling not to replace it. I would say that the key benefit is that the introduction of piped systems will enable the catchments of urban drainage areas to be represented more accurately which in turn should ensure that a more robust method of determining the dynamic outflows of piped systems into open channel systems improving modelling outcomes for open channel systems in these types of catchments.
@gfunkstube Thank you a lot for your clarification. I fully appreciate that
Thank you - Please expecting more examples
I am trying to simulate a 1D pipeline along with a 2D Mesh, but I encountered this error "1d Post Process Skipped hecras"
is there option for rational method hydrology and auto design of conduit?
Great video! Thanks for sharing
Hello, I am a new developer for RAS Mapper. Can I have your email ID to communicate?

Great video
Hi, I am the primary developer for RAS Mapper, I made a lot of the map interaction, mapping results, profile and hydrograph plots for stormwater pipes. Great job on covering how to model stormwater pipes in RAS, you hit all the major points.
Thank you! I'm really impressed with how smooth the functionality is with the beta release! Great job to you and all the HEC folks for pushing the boundaries of hydraulic modeling! It's an exciting time to be a modeler!
Please share some tips
what are the values you entered when you edit thesteady flow
What is the DEM resolution used in this model?
Thanks for the video, is there any way to generate unstructured mesh using break lines, I mean unstructured mesh for whole the 2D flow area.
READ_UN_MET_PRECI 233 Read_UN_Met.for Error with program，when i run the official example about grid precipitation.How could i solve it?
Hey, I like how you are technically sound while explaining your tutorials. I wonder if it could be possible for you to make a set of videos with different topics like dam breach, sediment transport and other common topics. Thanks so much for this. :)
Please, complete the model with a bridge
good
thanks for sharing this content
Brilliant! keep it up!
Hi, Bro the Cross-section data! Which You open at 18:42 in Video. the Coordinates mentioned. Are they already mentioned? or RAS Mapper GIS survey data automatically Imports from there? Please Reply. Thank You!
Thanks for sharing! Would you mind teach how to use the Meteorological Data tool to load raster file? That would be helpful and no one did it before on the TH-cam.
Promo SM 😁
Is it possible to draw a rectangular channel? Or is only possible in 1D model?
yes it's possible
Hi, thank you for your video. I have a question. If I have computed my rainfall excesses previously, so I suppose that I would not need an infiltration layer right?
Correct, if you compute your rainfall excess outside of RAS you would not need an infiltration layer. Keep in mind that if you want or need to have spatial variation in your infiltration, you will need to use gridded excess rainfall as an input to your RAS model. Hope that helps!
Hello sir! I am a masters student. I need to do floodplain modelling. Could you please help me? Is there any way to contact you?

Hi! Awesome content! Could you please make a dam break model? With hydrograph inflow into the reservoir, dam breach parameters and the outflow results, please?
From the presentation.. I beleve this guy can do way more than the dam break model.
Please send the educational files
Would you be interested in giving help with a project or a one on one tutorial?
I would be open to that possibility. Let me know if there's a way I can reach out to you directly!
