1D output - SHistory / sediment flux

dummy@example.com (SBF) — Mon, 07 Jul 2025 06:29:39 +0000

Hi Everyone,

the answer is, that the second column is the sum of all grain classes = the whole sediment flux in this profile:
# cross_section-> 75009
# time sediment_flux_[m3/s]
3.0393264 0(=sum) 0(=grain class 1) 0(=grain class 2) 0(=grain class 3) 0(=grain class 4)

This should be the accumulated (integrated over time) bed load volume (without porosity) in m3. This is done for each cross-section and then plotted along the river axis.

Hope this helps!
cheers, Lukas

Output volumes

OK I guess I figured it out, sediment volume is just total of sediments as you input, deposition is sediment+porosity?

Output bedload fluxes

dummy@example.com (Alyssa) — Mon, 19 Oct 2020 09:25:49 +0000

When I compare MatFlux.dat, I get the same results as copy_out for bedload fluxes. But the copytecFlux.dat gives something else, why is that? Is it not supposed to give the same data?

thanks

Alyssa

Result visualization

We have started implementing support for 1D element in MDAL/QGIS directly:

If you are interested in supporting BASEMENT data, feel free to get in touch.

Cross section visualisation

dummy@example.com (patrickbaer) — Fri, 09 Mar 2018 10:28:16 +0000

Hi everybody,
the HSR scripts for 1D longitudal profile visualisation are very useful. However, as stated already before, the versions have not gotten any update for a long time and I'm missing some similar possibility for plotting cross sections.

Before starting to script something myself, I wanted to ask if some scripts for this purpose already exist at HSR or VAW or from any other user?

Thanks for some advice,
Patrick

Lateral weir output

dummy@example.com (v_ivanov) — Tue, 06 Dec 2016 10:49:20 +0000

Hi there

I am modelling a flood scenario with Basement and I would like to estimate the outflow discharge. For the purpose, I use HYDRAULICS -> SOURCE -> off_channel and define two consecutive cross sections. However, I am struggling to understand the resulting output. What I get is two files, tagged with names CSnameDownSink and CSnameUpSink. While the DownSink file seems to be relative to the downstream section of the weir, the UpSink file carries the name of the cross section further downstream of the downstream end of the weir (see image http://www.dropbox.com/s/bf1tzj4gsxl087j/weir.JPG).

So, how should I interpret the content of the two files? Or maybe I omitted something to be defined within the Output block?

Thank you in advance for your help!

Output for losses and coefficient

dummy@example.com (Gonne) — Wed, 02 Mar 2016 16:18:16 +0000

Hi,
I have done the Arno river simulation but I can't see the losses at the bridge piers and the contraction and expansion coefficient. How can I do? Which SPECIAL OUTPUT I have to put in the simulation?
Thank you

thanx stephan

how to visualize results

Sir Stephan ,

thanx for the reply . i got my answer .

Balance_value

dummy@example.com (Lukas Vonwiller) — Wed, 21 Oct 2015 08:45:43 +0000

Hi farman

There is the output 'delta_v_sed' and 'delta_v_water' which will give you the counter part of the 2D balance_values 'sediment' and 'water_volume'.

Hope this helps!
Best, Lukas

baseviz

dummy@example.com (Lukas Vonwiller) — Wed, 21 Oct 2015 08:36:04 +0000

Dear Adnan

BASEviz can only be used for single 1D or single 2D domains.
Coupled domains can't be visualized with BASEviz.

Best regards
Lukas
