S-Risk updated to 1.2.5

Today, a new release of S-Risk (version 1.2.5) was made available online. More information about the modifications done can be found in our Release note.
We advise you to carefully read this note as some adjustments made to S-Risk, might affect your simulations!
When having questions, do not hesitate to contact us!
 

S-Risk offline for 1.2.5 update

Update on 29/03/2018 11.20 am: The 1.2.5 update will take longer than expected. We do our best to make S-Risk available to you again as soon as possible. We would like to apologize for this inconvenience and thank you for your understanding!
-----
Next week, on Thursday, March 29, the 1.2.5 update of S-Risk will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 11 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.
 

S-Risk 1.2.5

This release includes a number of fixes and some maintenance and parameter adjustments.

General fixes & changes

  • Fix for incorrect water-filled porosity in the capillary zone (θwcz):

    By default, θwcz amounts to 0.34 (FL/BRX) or 0.391 (WAL) for the "generic" soil layer type. However, for a newly created simulation – which has one “generic” standard soil layer by default – this parameter was systematically set to 0 instead of the correct default value. For all other simulations, i.e., simulations where the default “generic” soil layer has been replaced by (an)other soil layer(s), the correct (default) value for θwcz is set. Also, in simulations where a second/third/… generic soil layer has been added, the correct (default) value for θwcz will be taken.

    We have discussed this issue with the FL, BRX and WAL government. In case the involved simulation(s) is (are) resulting from a closed file, you don't have to do anything. In other cases, i.e., when you want to make re-use of an involved simulation (created before release 1.2.5), either for creating a new simulation (by using the copy function) or for doing new calculations with the respective simulation, you manually have to adjust this parameter value. How can you do this?

  • Switch to Tier 2 mode and go to the “Soil” tab;
  • Select the generic soil layer, click on the “Customize” button and modify the soil layer name;
  • Behind "θwcz (m³/m³)", enter 0.34 (FL/BRX) or 0.391 (WAL) instead of 0.

    Contact us via info@s-risk.be if you have further questions!

  • Changed thousands separator for numbers to space, to avoid confusion with decimal numbers. 
  • Adjustments to summary report, so it will be saved correctly to PDF in Chrome.

Parameter adjustments

The Walloon government decided to change the toxicological threshold values of some default WAL chlorinated substances:

  • for hexachlorobenzene, the values for systemic threshold effects have been changed:
    • oral TDI and dermal TDU: 5.0E-5 mg/kg bw/d;
    • TCA: 2.45E-4 mg/m³;
  • for pentachlorobenzene, the TCA value for systemic threshold effects has been changed: 2.8E-3 mg/m³;
  • for 2,3,4,6 tetrachlorophenol, the TCA value for systemic threshold effects has been changed: 0.35 mg/m³.

Please, be careful when making re-use of simulations (created before release 1.2.5) containing these substances, either for creating a new simulation (by using the copy function) or for doing new calculations with the respective simulation! In both cases, you manually have to adjust this parameter value. How can you do this?

  • Switch to Tier 2 mode and go to the “Chemical” tab;
  • Select the appropriate chemical, click on the “Customize” button and modify the chemical name;
  • Go to the “Risk” tab and select the respective chemical;
  • Within the “Threshold effects – Systemic effects” panel, enter three times the appropriate value for TDI, TDU and/or TCA.

S-Risk offline for update

We will maintain our operating system. Therefore, the S-Risk web application will be temporarily unavailable between coming Monday (January 29) 4 pm and Tuesday (January 30) 12 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.
 

Helpdesk availability over the holidays

The S-Risk helpdesk will not be available over the Christmas holidays (starting December 25, 2017). Please keep sending your questions over, they will be answered as soon as possible from January 8, 2018 onwards.
 

User manual updated

The S-Risk user manual has been updated to reflect the latest changes introduced with S-Risk 1.2.3 and 1.2.4. You can find English and Dutch versions on our Documents page.
 

Updated FAQ entries

We have updated the following FAQ entries:

  • How to simulate the presence of a paved surface?
  • What are the browser or network requirements for running S-Risk?

 

S-Risk updated to 1.2.4

This morning, S-Risk has been updated to version 1.2.4. This is an interim release containing a model bugfix and improvements to optimize network traffic to the S-Risk servers - see the Release Notes for full details.

S-Risk 1.2.4

S-Risk 1.2.4 is an interim release containing a minor fix and some improvements to the web application.

  • fix for handling of Kd factors in situations with a separate infoor profile, for metals without a Kd formula
    Users with simulations that were possibly affected by this, have been informed by email.
  • several fixes to optimize network traffic to the server

S-Risk offline for 1.2.4 update

Coming Monday, June 26, the 1.2.4 update of S-Risk will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 10 am.
Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.
