Hello all! I'm trying to model a river in HEC HMS for my MSc thesis. I'm using GeoHMS to prepare the input data for the model. The problem is that the river has two outlet points due to an existing diversion before deltaic part. The diversion was constructed for flood management. I'm trying to set the diversion point in GeoHMS with no success.…(Show moreShow less)
Hello Mr. Mark Boucher, I am Jomar, and I am new in using ArcHydro and HEC GeoHMS. I wanted to ask for your help regarding the error that I have encountered in generating my project in HEC GeoHMS. I always encounter this problem whenever I generate a new project. The error reads as: "System.Runtime.IteropServices.COMException (0x80004005):…(Show moreShow less)
Hello All, I am getting error when I check data with HEC Geo HMS for modeling into HEC HMS. The error log file shows the following error: Checking project points [VIP points]... Checking VIP Point: Outlet1 x=784893.2932, y=4502612.2667 End of checking point: name=Outlet1 oid=1 - PROBLEM: outlet point does not have right river connectivity.…(Show moreShow less)
I had the same problem. Use the edit tools to move you outlet and snap it to the very edge of the sub-basin where the river feature intersects the sub-basin layer. Errors related to the outlet point should then be cleared.
I have generated a terrain dataset for South Africa from 20m contours and SPOT shots. In order to eliminate errors in the terrain where there isn't enough data especially low lying areas. I would like to make use of river centerlines to enforce the drainage within the terrain dataset. My proposed methodology is to intersect the river centerlines…(Show moreShow less)
Dear all, I'm having a problem with Arc Hydro for ArcMap 10.4.1. When I try to do the Dem Reconditioning, the Arc Hydro crashes and Returns: Error hresult e_fail has been returned from a call to a com component. at ESRI.GEoprocessing.GeoProcessorClass.Execute(String Name, IVariantArray ipValues, ITrackCancel p TrackCancel) at…(Show moreShow less)
Hi there! Currently I'm following a GIS course, via Coursera.com and one of the exercises was to create a streamorder layer. After following the exercise and completing it without problems, I tried to do the exact exercise for the area where I live. This is in San Cristobal de las Casas, Chiapas, Mexico. I found the DEM files (.bil) that I…(Show moreShow less)
I didn't see whether 'sinks' were filled or whether you were working with a depressionless DEM. If it isn't, you won't get satisfactory results as outlined here Creating a depressionless DEM—Help | ArcGIS for Desktop which is a prerequisite for pretty well everything in your workflow
Hi, I have downloaded the arcgis version 10.4 and I need the Archydro tool to work on it. Does anyone knows if there is a version of archydro for arcgis 10.4? Or do i need to download other version of Arcgis? I thought wierd because I got Arcgis from free trial on esri and they gave me version 10.4 and for other friends who did de same, other…(Show moreShow less)
Mark, Why install the older 10.4.0.3 (2016-02-06) build instead of the 10.4.0.12 (2016-07-13) build? Ignore the ASCII sort order the Web server lists in, and go by the build number/date to keep current. Stuart
hi, use ArcHydro occasionally but I'm not too familiar with it. I had been using Arc Hydro 10.2 with ArcGIS 10.2 for a while and recently upgraded to ArcGIS 10.4. I then had an error in running one of the ArcHydro tools (Stream segmentation tool, error was "ArcMap has stopped working") and realized I probably needed to upgrade to ArcHydro 10.4…(Show moreShow less)
I discovered this also after having lots of problems getting Arc Hydro (supposedly 10.4) to work without crashing. It must have crashed a dozen or more times yesterday (10/4/2016). I still did not get done what I wanted to get done. Skeptical it'll work right today. Considering simply using Spatial Analyst tools to get this problem done. Has…
Hi. I want to do flood zone modelling and am using Arc GIS 10.4. The HEC-GEORASS in the MFT site is only for 10.3. Where can I get ArcGIS 10.3? Can I use my lisence for 10.4 in 10.3? Alternately, Where can I get HEC-GEORAS for ARC GIS 10.4?
Hello, I'm trying to build a Geometric Network to run my Arc Hydro analyses on NHDPlus Data. When the process of making Geometric Network finishes Arc reports "Drainage_Net_BUILDERR" error table has been created. I checked all 10 ObjectIDs listed in the table and it seems like they are small loops/single lines attached to the rest of the stream…(Show moreShow less)
