Hello Peter This is quite interesting. I am also currently working on 51 km of a whole new railway line (with velocities up to 260 km/hour). So I have some comments: - What do you mean by structures? Is it bridges and/or dams? Underways for rivers, channels and/or roads? - I suppose that, when you say alignment, you mean a CAD file where the alignment (on 2 dimensions) is shown, right? Or you mean the DTM of the railway? Because converting a 2-D alignment to a raster grid does not make much sense to me. Right? Assuming you have a new DTM for the railway, and another DTM for the existing terrain area surrounding the railway, then what about doing this?: - Merge both terrain datasets, but make sure to give highest priority to the new railway DTM, so that this "comes on top" on the merging process. - With the result, a simple Cut/Fill operation should give you the areas where your new DTM is above/below the existing terrain - Alternatively, with the merged DTM, run ArcHydro Terrain Pre-processing functions, all the way down to mapping of Depressions and the Flow Direction Grid. These results will indicate where you have low areas requiring culverts, and where water would flow from/to. Hope this helps! You are welcome to ask/comment on my suggestions.

Hello Stuart Thanks a lot for your answer. It clearly helps to understand the situation. I will try to get an SSD hard drive instead. However, my knowledge on these issues is limited, and I could use some references. Do you have some links, papers, documents, regarding the issue of: - "partitioning my data into multiple FGDB to avoid concentration and lock conditions" - How would this partitioning cause my ArcGIS and ArcHydro processes or results to run as multiple threads? I mean, by partitioning I understand splitting my input data into several file geodatabases, right? Again, thanks a lot for the quick answer. Hope you have some extra material I can digest 🙂 Kind regards, Alvaro

Hello everyone I need to use ArcHydro on a big railway project covering an area of 50 x 20 km. My experience tells me that I would need to split my terrain model in small pieces, in order to get the hydro calculations to work. I want to avoid that, and instead find a way to run the whole raster extent. I have only tried with Windows XP 32-bit system. Therefore I am looking for alternative options to run ArcHydro, and thought about installing it on a 64-bit computer with Windows 7. I use ArcGIS Desktop 10. Questions: - Can ArcHydro run on a 64-bit Windows 7 computer? Are there any special requirements? - What are the advantages/disadvantages of running ArcHydro on such a computer? - Any comments on previous or similar experiences are gratefully welcomed. - Could there be any conflicts with CAD programs, like MicroStation for example? Finally, here are the specifications of the computer I am considering: Base Unit HP Z600 RDIMM Workstation Chassis HP Z600 650W 85% Efficient Chassis Operating System MS Windows 7 Professional 64-bit OS Processor Intel Xeon X5650 2.66 12MB/1333 6C CPU-1 Processor 2 Intel Xeon X5650 2.66 12MB/1333 6C CPU-2 System Memory HP 16GB(4x4GB) DDR3-1333 ECC 2CPU RegRAM Graphics Card NVIDIA Quadro FX580 512MB Graphics Hard Drive 1 HP 250GB SATA 7200 1st HDD Keyboard HP USB Standard Keyboard Mouse HP USB Optical Scroll Mouse Floppy Disk Drive HP No Floppy Disk Option Optical Device 1 HP 16X DVD+-RW SuperMulti SATA 1st Drive Country Kit HP Z600 Localization Kit HP Care Pack Services - CTO/BTCO only (AV) HP 3y NBD/Disk Retention WS Only SVC Workstations LS Std delivery (Door/Dock) AV workstation Thanks a lot!!!

Hello again I can see there are 46 views on my previous thread about Flow Direction with Sinks, but no reply at all 😞 I have now formatted my computer, and re-installed Windows XP with the latest service pack. I have also installed Arc Hydro 2.0, with the hope of losing the problem, but I am close to concluding there is an error in the code (visual basic programming) of this function. Could it be? Here´s a description of what I have done: - I have a GRID raster file (5x5m) covering an area of about 460 km2 (Uncompressed size: 71.20 MB). Format: Continuous Double Floating 32-bit - I have two feature datasets: a polygon layer for lakes, and a polyline layer for streams - I create my geodatabase (gdb file) and the corresponding target locations for my results - I run the Terrain Pre-processing functions, to which I get the corresponding results: LevelDEM, AgreeDEM, etc. My focus is on Depressions, rather than Sinks, so I use the Depression Evaluation function, and I produce my filled DEM using these depressions. So far so good. - The problem comes when I run the function Flow Direction with Sinks, using my Depression polygon layer and my filled DEM. I am attaching two pictures of what it seems to be the same error, both when I run it directly from the Arc Hydro toolbar and when I run it from a Model using the Arc Hydro toolbox. As you can see, the error points to what it seems to be a very generic error in visual basic programming, namely something with "System.Runtime.InteropServices.SEHException: External component has thrown an exception". Or, from my attempt with model builder: "Error HRESULT E_FAIL has been returned from a call to a COM component". Then, in both pictures, the error refers to a path, which does not exist on my computer: C:\Projects:\10_Final\ArcHydroTools\src\ApHydro\ArcHydroOp.vb:line 4356 As mentioned, I do not have a folder called 'Projects' on my C drive. What is happening? Is Arc Hydro attempting to write or get data from a path which does not exist, and therefore the function crashes? If so, why is it doing that and how I can change it? Finally, a quick comment. I have 5,025 depressions where the attribute IsSink is set to 1. Therefore, these are the depressions that Arc Hydro uses to calculate the flow direction with sinks. As you can see from the error messages, in the end of the (unexisting) path, it says line:4356 and line:4358, respectively. This matches well with what I could see from the Geoprocessing model window, where it said that the Sink Point layer was about 78% done, just before it crashed. I should mentioned, to finish, that this is the first time I have had problems with Arc Hydro, more specifically with the Flow Direction with Sinks function. About 3 months ago, running with Arc Hydro 1.4 on ArcGIS 9.3.1, I ran exactly the same workflow, with no problems at all, on the same computer. I actually formatted the computer in order to start "from scratch" with my new ArcGIS 10 and Arc Hydro 2.0. Unfortunately, it has not worked. Any help would be deeply appreciated. Kind regards to everyone, keep up the good work 🙂

I have just installed ArcGIS 10 on a newly formatted computer, and also installed ArcHydro 2.0, and it seems to work much better than the previous versions (9.3.1). They have done a lot of improvement, especially adding some functions in the ArcHydro Toolbox, so that one can run Model Builder with more functions now. However, there is one thing I cannot find, a function called Accumulate Shapes. It´s still on the help documentation, but I just cannot find it. Any ideas? Cheers, Alvaro

Hello folks! I cannot find the function "Accumulate Shapes" under Terrain Preprocessing. I have just installed ArcHydro 2.0, running on ArcGIS 10 (ArcView single use license), and although there are very nice improvements, I am missing this function. Any idea? Good weekend to everyone!

Hello folks! I am running the function "Flow Direction with Sinks" in Arc Hydro version 4, and I get the message you can see in the picture. I am working with ArcView 9.3.1. Spatial Analyst. I ran the same function and same workflow about 3 months ago, without problems at all, so I do not understand what is the problem now. My setup is simple and it´s described in the picture called "Model", from Model Builder. Basically I have a polygon layer called Depression (obtained with the Depression function in Arc Hydro) and a filled terrain model (FilDepr), both of which I use as input in the function. Out of the 4 resulting files, there is only one which is created successfully: the point layer (DeprPoint). I have tried to run the function both using my model, and also directly from the Arc Hydro tool bar, but nothing works. Anybody can give me a hand on this? Please! Kind regards, Alvaro
