thanks krey! i actually took your class in AWS recently, its nice to see you posted a cascade of help videos even several years ago that i am just watching now. cheers!
With some basic knowledge about ArcGIS, shape file, Tiff and Rasta Imagine , your speech speed are very good. A lot of information and presentation was well done. Thanks for teaching us. Keep up...
I have watched this video about 20 times and each and every time I learnt something. one more thing, to get DEM files you can download it from earthexplorer.usgs.gov
Thanks - added the link to the description. A walk-through of the process of extracting EarthExplorer terrain data for use in RAS Mapper using is available in our HEC-RAS 6.0 series here: ua-cam.com/video/5VtUVpHyY0I/v-deo.html
Hi! I´m doing my masters thesis on Two-stage ditches and looking at erosion to evaluate the effectiveness of these ditches in Sweden. I have not used Hecras before so I´m wondering if this software handles smaller watercourses and if its possible to adjust the settings according to soil types in this software?
Hello Krey! First of all thank you for your YT videos, I have been learning a lot from them. I do have a question tough. In the header of this video, it does seem that you modelled a culvert through an existing roadway embankment. How did you do that? Every time that I need to model a culvert through an existing embankment, I need to modify the terrain using RAS-MAPER and then, model the embankment as it was a bridge. Thank you sooooo much :)
Hello thanks for all the valuable information in this course. I have a problem. my options tool in Ras Mapper doesn't have all the options. I don't have "set projection for Project". what's the reason?
excelente tutorial ingeniero de verdad muchas gracias les saluda desde peru. una sugerencia para descargar la topografia del area de estudio por la plataforma elvis no accede o u otra manera de descargar la topografia mas precisa por favor. gracias y saludos
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
Thanks so much, very informative. I'm in the UK and can't seem to find a website with free DEM with 20 cm in 20 cm pixel size to use in HEC-RAS. Is there any and could you please tell me how to get them. Thanks
لقد أرسلت 25 مايو الساعة 2:13 م Hello, how are you? I want to download the hec ras program (6.0,5.0.7,5.0.6,5.0.5,5.0.4) where I encountered an OPNE RAS problem that did not work for me please I want a solution
Hello, I am new to HEC RAS and I am encountering a Run-time error '9' Subscript out of range when importing a geometry file from AutoCAD civil 3D to HEC RAS. Any idea why this is happening?
if i am using HEC-RAS in US-Feet, does the projection need to be in US-Feet? i downloaded the project for UTM 15N but it is obviously in meters. Should i just leave the cross section river stations in feet? Thanks! The file i am uploading is a combined DEM + survey surface that i have exported from Civil 3D to a DEM as well. That was all done in the UTM 15N projection but in US-Feet...
hello sir we are trying to run a flood simulation for our state , Kerala, INDIA, as have shown in this video, while pressing create after uploading the tif file of terrain its showing a error message, what to do, waiting for your reply.
Good afternoon. Dear, my name is Bruno. I'm a civil engineering student in Brazil. I need to carry out a simulation of the rupture of an earth reservoir for water storage located outside the water course. My question is whether Hec Ras allows me to carry out this type of simulation or if Hec Ras is just a simulation of structures in the water course. Is there any software that allows me to simulate the rupture of an earth reservoir to accumulate water outside the water course?
Hi, for the terrain and projection data. I'm struggling to get these data. I've been told to use National River Flow Archive and OS Terrain 50 for the UK but honestly can't find the data in these websites. Do you have any suggestions please?
Hi Craig. Can you possibly give me a hand with a VERY interesting project in Western Africa? It could help an awful lot of people, but I need to be sure of the ancient waterways. No offence, but I just can't seem to wrap my head around HEC-RAS. It's like German documentation to me.
Hallo. I had a finally problem with my ras project. I would be greatful if you could help me. I want to display the depth of 2d flow to a real map. I set the projection to ras mapper but when I click map layers> add web imagery layer>google hybrid, seems to be a problem and when a place the mouse over the file there is this message : "Error loading image from file C:/Users/..../tif does not exist in the file system and is not recognized as a supported dataset name'' Thankyou.
Hello. I have sent countless requests for Bisbane's terrain data with different mail accounts but no one has sent me a mail for the data download. What do I do? Thanks.
Hi all. Very useful video. Only one problem. I can not load any wms layer. Even for the examples. I am using the correct projection though. Any help? Regards , Petros
Hey, I am a student from a higher technology college for civil engineering. I am working on my diploma thises right now and I am struggling with HEC-RAS. Noone of my professors has ever used it before or at least not on such a high level. Is it possible to import a terrain file (XYZ file) that includes "." as commas and "," as separation? And if not, do you have an idea how I can change this into the Metric System?
You'll need a raster grid digital elevation model. Point clouds won't work, even if the points are sampled on a regular grid. You could do a find and replace in the text file to change the separators if necessary, but you'll also need to do a conversion to a raster grid using other software (AutoCAD/Civil3D, ArcGIS, etc. have conversion features that take point files and convert to raster grid DEM). Appendix B of the HEC-RAS 2D user manual lists the supported file formats.
Draw a profile line across the flow path, then right-click on it and select "Cumulative Volume" under time series, which essentially computes the area under the hydrograph. The results can be shown graphically or select the "Table" tab to copy and paste the numbers into Excel. If the simulation window has run long enough for the cumulative volume curve to flatten to a constant value, the final value will be your total flood volume/flux across that particular profile line. If this is computed at the inflow and outflow locations, the difference in volumes should equal the system storage.
If RAS Mapper does not open, typically it is an issue with a 32-bit operating system (since RAS Mapper is 64-bit). It won't work on a 32-bit operating system, and sometimes still has issues with a 64-bit system if it's out of date. Best to install all Windows updates (windowsupdate.microsoft.com) including .net framework, and reinstall HEC-RAS if necessary.
Thank you for the great effort. I can send you a batch to make multiple folders at once instead creating them one by one. If you are interested, reply with your email.

It is my first contact with HEC-RAS and this video is very helpfull. Will chech out your other HEC-RAS educational videos. Thank you a lot.
Thank you! Appreciate the (quick) pace and level of detail, very useful
I like the way you teach how to start doing modelling rather than jumping straight into the model set up.
You got 1+ subscriber from India.... Thank you for putting so much efforts
It was like watching your favorite movie!!!!
So informative video.

If the simulation window has run long enough for the cumulative volume curve to flatten to a constant value, the final value will be your total flood volume/flux across that particular profile line.
