I want to simulate water flow at open canals and irrigation water networks in ArcGIS
Is there any tool help me?
I can help you. I use HecRas and HecGeoras in ArcGis.
You can download my tutorial ... http://www.urbanismogranada.com/manuales.php
(in spanish)
You can build your model in ArcGis using HEC-GeoRAS, run the simulation in HEC-RAS and then export the results in ArcGis.
@adriana maria,
thanks, I've tried HEC-GeoRAS before for another function , i will try it again
@fluvio rivano ,
do you mean HEC-GeoRAS ?
it's a tool-bar in arcGIS
Ok , it's frist time to know it
could you send me a link to download it ?
There is a tool that can help you, and is called mike flood.
With this, you will be able to modelling what you are looking
HEC's "GeoRas 's 10" ArcGIS extension link is http://www.hec.usace.army.mil/software/hec-georas/. Best used with HEC's "HEC-RAS" program link is http://www.hec.usace.army.mil/software/hec-ras/
thanks alot :)
1-the input data in HEC-GeoRAS is raster but the data that i have is shapefile
2- i tried archdro before but it's unuseful to me
i will try iRIC, SMADA , and mike flood
I believe there is a "gridding" extension that will convert a 3D vector file to an ArcGIS grid. I can't remember the name of the extension, but may be someone else can provide it.
I assumed you had a shape file. A 3D contour mapping would have the elevation in the ".shp" file. I believe the conversion requires both the Spatial Analysis and 3D Analysis extensions. I hope this clears up my comment.
I am sorry. You need to speak face to face with someone with experience using ArcGIS. That person will be able to show you how the conversion is done.
i need someone with experience using HEC -GeoRAS
i am a beginner in it
I believe that you need first configuring a network with active nodes in your shapefile and then using Hec- GeoRAS or assess the utilities of ArsGis for hydrological analysis (basic functions).
There is a tool. You can use spatial analysis tool and use arc hydro which incorporated now if using 10.0, 10.1, or 10.2. You can use flow direction tool, flow accumulation

Canal man is a good model for simulating flow in irrigation canals.
Your best option is HEC-RAS version that works with ArcGIS. Other option is ArcHydro. But if you are focusing on open channel hydraulics, then you might want to use HEC-RAS, it has a lot of tools that will make your life easy. You can specify streams, rivers, cross-sections, bridges, elevations and so on. If you want to bring in the effect of surface runoff, that may be a little bit of a challenge.
may i ask a question ??
can i use HEC-RAS for manning equation for water velocity
You can set different values of Manning for the different zones of each cross section of your model. You will get water levels and velocities for each cross section. You can then export your results in arcmap using HEC GEO-RAS, obtaining rasters with the distribution of water levels and velocities throughout the whole channel.
Ok that's what i want , but still have a problem
the data which i have isn't raster , it's a line feature class
What does this line represent? is it a PolylineZ representing the profile of the channel? do you have cross sections?
The feature class represent the water canals
i have the date to calculate cross section , water level, water velocity
i planned to develope a model to calculate it
If you have problems in using ArcGIS and want to try and open source alternative, you could probably have a look at this guide for "Estimating a Base Flood Elevation using QGIS": http://wvfma.org/wp-content/uploads/2013/05/Estimating-a-BFE-with-Quantum-GIS.pdf
I kindly request you to use Hec-Geo-Ras Extension in Arc-GIS frame work. Arc Hydro (which is also an extension for Arc GIS) might be useful.
Good luck,
Mohammad
you can use arc swat tool with Arcgis environment for your purpose
