UPGRADE HISTORY

Update released on January 11, 2018

  • On the scenario page, selection of the base condition year and base condition projection method are two separate choices. This reduces the items in each drop down list to make the selections more clear. Historic Trend base condition remains available. The Current Zoning base condition will become available in the coming weeks. Other base conditions may become available in the future.
  • The loads report is newly formatted to facilitate analysis. It now only has one header row.
  • All reports have additional information included to more clearly identify the geography.
  • Reports types are sorted alphabetically.
  • Results are returned faster on the Compare Scenarios screen.
  • The 2014, 2015, 2016 and 2017 Progress scenarios are being finalized. Different versions are released on a regular basis. Once the final version is approved inteh spring, earlier versions no longer will be available in the shared scenarios list. 
  • Application version is 4.10. Model version remains unchanged and is CAST-2017. 

Update released on December 21, 2017

  • The model version is now final. The Draft Final 12/7/2017 version of the model was approved by the Chesapeake Bay Program Partnership's Principals' Staff Committee and is now named CAST-2017.
  • The next updates to the model methodology and assumptions are scheduled for 2019. The user interface may continue to be upgraded. New data, such as base conditions, may continue to be added. 

Update released on December 12, 2017

  • Local area planning targets link added to home page. The targets will be added when the final version of the draft targets are available.
  • Functionality for sending email to all CAST users is added.
  • Tuned several functions to make them faster.
  • Minor bugs on the user interface were fixed.
  • Bug with sharing scenarios that removed results is corrected.
  • CAST user documentation updated.
  • Corrected the unit on the Compare loads tab to pound per year.
  • Removed septic from the Compare acres grid since septics are a direct load to the stream and do not have acres.
  • Added data version and application version to the Source data download table.
  • In reports grid, the name of the report pops up when you hover over it. This allows users to see the full name where the names are long and have no spaces.
  • Application version is 4.9. Model version remains unchanged and is Draft Final 12/7/2017. 

Update released on December 7, 2017

  • Updates change the loads in your scenarios, scenarios shared with you, and public scenarios including No Action and E3.
  • A new method for distributing phosphorus inorganic fertilizer is implemented. Nutrients are spread using the phosphorus fertilizer application curves, as was originally intended by Chesapeake Bay Program Partnership decisions. This corrects an issue that occurs in situations where there is less manure transported in a scenario compared to a reference scenarios. This issue was identified with testing of the nutrient management BMP.  
  • The estimation of water extractable phosphorus in counties where there is more than one land segment is corrected.
  • Updated broiler and turkey animal counts for 2014 to 2016, and projected to 2025, are included.
  • Updated broiler data for 2014 to 2016, and projected to 2025, are included. Data include the number of animals per animal unit and the amount of manure produced per animal. 
  • New animal counts means that the land use changes. The animal counts are used to determine the area in the feeding space land use. This impacts all land uses for years 2014 to 2025.
  • The amount of animals in regulated feeding spaces versus non-regulated feeding space is updated.
  • The method for generating the final land use and septics has changed for 2014 to 2025. This affects the Historic Trends land use. 
  • The method for determining the developed land turfgrass application rate is updated, affecting loads for 2014 to 2025.
  • Corrected 2016 point source data is included.
  • The wastewater data for the District of Columbia was revised for the 2010 No Action and E3 scenarios. 
  • Model version is updated to Draft Final 12/7/2017. Application version remains unchanged and is 4.8.

Update released on November 28, 2017

  • Updates change the loads in your scenarios, scenarios shared with you, and public scenarios. The shoreline load used for the E3 scenario was changed to have the shoreline BMP added to an additional 10% of the unimproved shoreline. The shoreline load for the no action, or no BMP, scenario is now equivalent to 2008. All other scenarios use the load from 2008 with shoreline BMPs reported after 2008. This decision was made at the Chesapeake Bay Program Partnership's 11/27/2017 Water Quality Goal Implementation Team meeting. All scenario loads are recalculated for you. 
  • Model version is updated to Draft Final 11/27/2017. Application version remains unchanged and is 4.8

Update released November 9, 2017

  • Updates change the loads in your scenarios, scenarios shared with you, and public scenarios. Public scenarios and the shared scenarios owned by CBP Admin are recalculated for users.

    • Model version updated to the Draft Final October 2017 version. This is consistent with the latest Phase 6 calibration that is being presented to the Principal Staff Committee in December.

Update released July 14, 2017

  • Updates change the loads in your scenarios, scenarios shared with you, and public scenarios. Public scenarios and the shared scenarios owned by CBP Admin will be recalculated for users. Users will need to run your scenarios to see the new loads. Just click on the green run arrow next to all of your scenarios. Scenarios can run simultaneously. The changes that impact loads include: 
    • Soil phosphorus — change how it is calculated in scenarios so it follows the logic used in the calibration
    • Biosolids — correct the method used to split into nutrient species
    • Cover management factor (C-Factor) — change method used in scenarios so the phosphorus and sediment loads vary with inputs.
    • Septic — include the updated population on septic.
  • Data version change from "Draft Final" to "Draft Final 7/14/2017".  
  • Application version 4.1.1

Update released July 11, 2017

  • Corrections were made to the public reports. The BMP submitted vs. Credited report was not including data in all three BMP sheets (land, animal, manure). The Loads report now returns the aggregation type selected by the user.
  • A system error was generated when deleting an edited scenario. This is now corrected so delete works properly.
  • Application version 4.1.1

Update released July 3, 2017

  • Public loads report is returning only BMP Summary report. Other report types made unavailable until corrections are made to the procedure to produce the report.

Update released June 15, 2017

This is the Draft Final version of Phase 6 CAST. Shared scenarios include:

  • Phase 2 Watershed Implementation Plan (WIP) BMPs translated to the Phase 6 BMPs, load sources, and model segmentation
  • Annual implementation scenarios for 1985 through 2013
  • Draft Everything, Everywhere by Everyone (E3). It is draft because it has not been reviewed by the Chesapeake Bay Program Partnership and there is no manure transport BMP in the scenario.
  • No Action, that is, no BMPs.
  • Application version 4.0.0

Update released April 3, 2017

This is the beta version of Phase 6 CAST made available for reviewing CAST functionality. Data are hypothetical and scenarios are temporary. Once the Chesapeake Bay Program Partnership releases the Draft Final version scenario data, CAST will be available for data review at CAST.ChesapeakeBay.net. At that time, new logins will need to be created and scenarios will be saved. CAST will be the model used for management purposes for the Chesapeake Bay Program Partnership. CAST 2017 and the Scenario Builder + Watershed Model are now the same model.
