How to Make a Smaller Model out of a Large Model in InfoSWMM

Subject: How to Make a Smaller Model out of a Large Model in InfoSWMMInfoSWMM and H2OMAP SWMM will export only those ACTIVE elements to SWMM 5 as defined by the Facility Manager. You can use the feature to make smaller SWMM 5 models and then reimport the exported smaller SWMM 5 model back into a H2OMAP SWMM or InfoSWMM scenario.…See More

SWMM5 into ArcGIS

Hello,I just want to know if there is a way to use the SWMM5 file in Arcgis in order to measure the elevation of junctions and the other dimensions as well. Or maybe somebody knows an other way to obtain them quickly. I've already 20 junctions.ThanksSedaSee More

In general these are the formats it recognizes for the next person // The following types of external data files are supported:// NWS_TAPE: NCDC NWS TD 3240 or 3260 data in fixed field widths// NWS_SPACE_DELIMITED: NCDC NWS TD (DSI) 3240 or 3260…

Thanks for the quick response. Does it matter if the file is space or comma or fixed-width delimited? D

Robert Dickinson replied to Derek Schilling's discussion 'Newbie question - importing precipitation files'

Hi, SWMM 5 will read and detect a variety of NWS and Canadian files - it figures out the format from parsing th e format of the data. It really does not matter if the extension is .dat or .txt - though it has a default of .dat. …

Newbie question - importing precipitation files

I've tooled around the forum for a while, but if there are easy hits on this topic they're eluding me.All I want to know (for now, at least) is where to find and how to import precipitation data into SWMM5 for a rain gage.I've downloaded files from the NCDC (DSI 3240), which come out as TXT files, either comma or space delimited. Are these useful to SWMM? It wants a DAT file, can I just change the filetype? Is the formatting of the NCDC's files alright for SWMM? I am in the process of trying to…See More

Robert Dickinson replied to Kashif Ali's discussion '10,000+ subcatchments to be assigned with outlets'

You also use a text editor - strip out the Subcatchment Section and then use use Excel just on the Subcatchment Section - of course you will then have to use a text editor to paste the altered Subcatchment section back into you SWMM 5 input…

Hello Robert, Here is the .inp file for your review, if you can see how large data can be handled by excel add-on http://www.mediafire.com/?a5u64plrksd3tec

Thanks Rui for your time and efforts to go through this project, By using GIS functions and adding fields in attribute files, the sub catchments are now linked with their appropriate outlets. Also, rather than, loading all hydrologic and…

Kashif Ali replied to Kashif Ali's discussion '10,000+ subcatchments to be assigned with outlets'

Thanks Robert, It really what I needed - without reading the manual, I was trying each option in the swmm to see if there is way to export the data in excel format. However, data being too large, excel simply says sorry with this message (This…

Please try inp.PINS and select inpTools --> Subcatchments connection (https://sites.google.com/site/inppins/) You can also edit inp text file, or even use GIS functions.

Rui Daniel Pina commented on MeHa's blog post 'ArcGIS data into SWMM'

inp.PINS worked just fine! Kashif, Please see the message I send you with my results data. The data you send me needed to be "SWMM formated". I did some of this: 1 - Assign invert elevation to nodes from links shp - GIS join; 2 - Define…

Maximum Surcharge Height Over Crown Explanation

Note: Maximum Surcharge Height Over Crown Explanation Here is an example of how the Maximum Surcharge Height over the Node Crown is calculated. Consider a manhole with an invert of 10 feet, one incoming pipe (Pipe A), one outgoing pipe (Pipe B), both pipes with a diameter of 2 feet, but the invert of Pipe A is 10 feet and the invert of Pipe B is 11 feet. What is the Maximum Surcharge height if the HGL at the node is 17…See More
