Automatic export to SWMM of these special structures
- is supporte in 13_vw_swmm_storages.sql and 02_vw_swmm_junctions.sql@TriformMoritz Do you need any others? -- 5372 -- "stormwater_overflow"?
I am not able to model anything different than a very simple weir inside QGEP yet. For example (BEP): https://vsa.ch/fr/wiki/3-2-13-bassin-deaux-pluviales-bassin-de-decantation-en-connexion-laterale/
I am not able to tell to tell how to model this (I tried) in QGEP
Please try yourself, I gave up after two hours.
The export to SWMM comes afterward. Concerning the SWMM export:
I have documented, how to construct the VSA-example 3.2.13 There is one real problem with the obj_id, that are automatic set as last_value+"-1" and therefor are too long (see also Issue #619 ) VSA Example 3-2-13 in QGEP.docx
There should be a new vw_overflow_line. And the network following should work also with this overflows.
My first problem: I cannot digitize, the error say : "Ajouter partie" at the end of my digitizing try:
I tried with two different projects I have - with the first one I get the same error as @TriformMoritz - with the other digitizing a detailed_geometry works fine. It is on the same database. The first node is within the network. The one that works is at the end (Vorflutereinlauf). When I try in that project file on a node within the network it also fails. So it looks not like a problem of the project file version. In German the message is 2022-03-07T16:59:52 WARNING Teil hinzufügen
Tested with QGIS 3.16.14
Found some information here: https://github.com/qgis/QGIS/issues/41294 that has been fixed in 3.20 (https://github.com/qgis/QGIS/pull/41391). @TriformMoritz Can you check with the latest LTR 3.24 if this still happens?
And this hint in the documentation:
If the geometry disappears after digitizing or if you get an message (like ‘Add part’), you have probably tried to digitize over a catchment area (or an other polygon theme) and the layer has set the avoid overlap option in the snapping settings. Do change the avoid overlap settings.
Very bottom of https://qgep.github.io/docs/user-guide/digitizing/digitizingdetailedgeometry.html
And here a screenshot of Snapping settings: In 3.24 it now gets more information - maybe you find out why it is invalid.
Works, thank you! The error message (of QGIS) should be clearer, like -> "Overlapping not allowed in snapping options" or "les options d'accrochage empèchent la création de la géométrie"
Add part-error: Stefan showed the solution. See also Issue #628
So it worked (I actually had all the weirs defined already, but they weren't visible and not exported to SWMM so I could not check), thank you Urs for the view!:
I would propose:
- Flow_valves (Limitateur_debit) are supported in VSA-DSS, so they should also be imported into SWMM-> Control curves.
@sjib Is their a corresponding table in QGEP datamodel? I'm not able to figure out which one.
- I am not sure if storage curves are supported in VSA-DSS.
@sjib Are they supported? Do they exist in QGEP?
Hydraulic classes in VSA-DSS
hq_relation and overflow_char (Ueberlaufchrakteristik) have the parameters needed for the SWMM curves (see chapter C.5 and 3.28. of the SWMM 5.2. User manual
Check whethe only Q-H relations are supported or also Q-Q relations (overflow_char.kind_overflow_char
- I am not sure if storage curves are supported in VSA-DSS.
@sjib Are they supported? Do they exist in QGEP?
What do you mean with storage curves? Do you mean hydr_geom_relation that describes the Relation between wetted section, wetted surface and height in a wastewater_node (e.g. bassin with special shape?)
Feedback from technical user group (2022.05.18) In the corresponding QGIS form a tab "overview" could be created to ease the exploration.
@TriformMoritz is there anything more action to do here?
It is crucial to easily to digitize and describe hydraulically special structure and export them for modeling, for this these points should be supported:
