This results in a 3% increase in the discharge of the orifice.  All existing models can be modified by a small adjustment to the orifice size to produce the same results.    The flow through the riser equation has been adjusted to account for a head condition above the riser greater than the riser radius.  This adjustment transitions the discharge from the weir equation to the orifice equation.  This adjustment will have little impact to most model results but can impact designs where there are significant head values on the riser.  The vertical orifice option for the Bioswale element was incorrectly applying precipitation to the element.  This will impact only bioswale elements using the vertical orifice option.",null,null],

Both issues are considered programing bugs.  According to the version numbering system in use as of October 20, 2015, the digits after the last decimal point are changed for this WWHM update. (1)- Fixed a bug that occurs when using the arched pipe option in the tank element.  The bug occurs in the last line of the stage-area-storage-discharge table.  Because the area at the top of an arched pipe is 0 the incremental storage = 0 and this caused an incorrect storage value for this line.  If the arched pipe never gets completely full then this will not impact the user.  However, if the pipe does get completely full you will get an error.  This issue has been resolved by making the incremental storage an extremely small (0.001 x value of prior stage) non-zero value. (2)- Fixed a bug that occurs in the SSD Table element with multiple layers. The SSD table would not refresh after the user pressed on the \"€œAdd Layer\" button and added another layer.  This bug likely resulted in SSD tables with multiple layers generating an incorrect FTABLE and incorrect results.  This issue has been resolved by ensuring the table refreshed after the user added a layer with the \"€œAdd Layer\"€ button.",null,null],

These issues are fixing a programing bug and adding optional utility features.  According to the version numbering system in use as of October 21, 2015, the digits after the last decimal point are changed for this WWHM update. (1)- Fixed a bug that occurs when using the time series element.  The bug occurs when connecting to an external .wdm file.  The connection can cause an error when searching the external .wdm file for datasets if no dataset is currently selected.  Fixed the issue by checking for a currently selected dataset.  If no dataset is selected then the model does not perform the check that causes the error.   (2)- Fixed the water quality sizing option for bioswales.   The option did not have tooltips so tooltips have been added that help document how to use the option.  Several options have been added for the user.  The user can select soil types and soil depths as well as the use of the either the simple swale or the fully functional swale.   Please note that the 2 new automatic sizing buttons in the bioretention element screen are intended to help users in sizing bioretentions for 91% runoff volume treatment (“Size Water Quality” button) and sizing for stream protection (“Size Facility” button).  WWHM users may still prefer to manually size bioretentions and ignore these buttons.  However, when these new buttons are used, any values specified in the dialogue boxes associated with these buttons will over-write the values in the main bioretention screen.  For example, specifying an “Infiltration Rate” of 0.1 inch/hour in the dialogue box associated with the “Size Water Quality” button will over-write any value in the field next to “Measured Infiltration Rate (in/hr)” on the main bioretention element screen under “Native Infiltration”.",null,null],

(1) – CAVFS module infiltration correction.  Under conditions where the width of the CAVFS is large the infiltration performance was underestimated.  This has been corrected.  CAVFS units should produce more infiltration and perform better.

Version 4.2.12 addresses issues related to generating project reports in \"pdf\" format, the wetland fluctuation report, the water   balance report, and the water quality report.  This also addresses an issue related to the auto-size feature for the 3 orifice   design.  These issues are considered a programing bug.  According to the version numbering system in use as of October 21, 2015,   the digits after the last decimal point are changed for this WWHM update.   In addition, Version 4.2.12 (Dated: 02-25-2016) adds Clark2012SG to the allmaps directory for use in modeling projects in Clark   County.   (1)- Fixed a bug that occurs when trying to perform a .pdf report before having run both the predeveloped and mitigated scenarios.        This issue causes the model to continue to report that the predeveloped scenario needs to be run even after the user runs it.     Fixed the issue by ensuring that the predeveloped run only needs to be run once.     (2)- Fixed a bug in the .pdf report related to the reporting of the water quality results.  This caused the report of water   quality results for every POC element even if the element had never had water quality computed.  This fix means that the .pdf   report only reports water quality for only those POC elements that have had water quality run.     (3)- Fixed a bug in the wetland fluctuation report.  There was an error where the model was reporting total volumes and the   heading said it was reporting annual volumes.  The model now reports annual volumes.    (4)- Fixed a bug in the water balance report.  There was an error in the volumes reported for specific landuse setups.  This does   not impact actual model results it only impacts how results are reported in the water balance graph.  This bug has been fixed.   (5)- Fixed an issue when running the 3 orifice design for tanks and vaults the routing could get trapped in an infinite loop.  The   issue has been corrected by improving the sizing routine so that it no longer gets stuck.   (6)- Added Clark2012SG to the allmaps directory.

Bioretention Modeling Recommendations: The two above changes have improved the modeling calculations accuracy when the Simple Bioretention option is used.  Using the Simple Bioretention option now gives identical results to the more complex Bioretention algorithm (the WWHM2012 default) under the following conditions: a)Native infiltration rate is greater than flow through the amended soil. b)Underdrain flow rate is greater than the flow though the amended soil. c)Both the native infiltration and the underdrain flow combined is greater than the flow through the amended soil. The two above changes have improved the modeling calculations accuracy when the Simple Bioretention option is used. Using the Simple Bioretention option now gives results within 1 to 4 percent of the complex Bioretention algorithm under the following conditions: d)Flow through the amended soil is greater than native infiltration. e)Flow through the amended soil is greater than flow through the underdrain. f)Flow through the amended soil is greater than the combined native infiltration and flow through the underdrain. Bioretention modeling using the Simple Bioretention option has always been multiple times faster than using the more complex Bioretention modeling algorithm (the WWHM2012 default).  With the improved accuracy and a relatively faster scenario run time, we recommend the use of Simple Bioretention in project modeling by checking the box next to “Use simple Bioretention”.",null,null],
