Subject: New Version of WEAP (2019.1)   
Posted: 4/26/2019 Viewed: 3214 times
A new version of WEAP is now available, with several new features and bug fixes. It is recommended for all users to get the update. As always, this new version is backwards compatible with data sets developed in earlier versions of WEAP.

If you have a problem with the automatic update, you can download the full installation from http://www.weap21.org/Download There is no need to uninstall your existing version first.

What's New:

- Catchment Delineation:
- Reading land cover data from NetCDF files: Previously, the data format was required to be integer. Now, it can be integer or floating point. However, all values must be in the range 0-255.
- WEAP is now much faster when updating complex catchments with many elevation bands and land cover branches in catchment delineation mode.
- Fixed bug in reading climate from NetCDF files: Data was not read if it was double precision floating point values.

- Priorities and Allocation of Water:
- Priority on Transmission Link: For demand sites and catchments, you now have the option of setting the demand priority directly on the transmission link, instead of the demand priority on the demand site and the supply preference on the transmission link. This could be useful if a demand site represents several demands which have different priorities. To select this option, right click on the demand site or catchment, choose General Info, then check the box for "Priority on Transmission Link?". You may also change the default setting for new demand sites and catchments on the Basic Parameters screen.
- Distribution Order: To distribute differing amounts of water to branches within a demand site or catchment in case of shortage, set a distribution order for each branch. If coverage < 100%, WEAP will distribute water first to branches with distribution order 1, then second to order = 2, etc. Enter data at any level of the Data Tree. A value entered at one level will be used by all branches at lower levels, unless a value has also been entered at the lower level. Leave all blank to distribute to all branches equally. By default, this option is turned off; to turn it on, go to Basic Parameters.

- MODFLOW:
- MODFLOW Pumping Reductions: When using MODFLOW-NWT and the UPW (Upstream Weighting) package, MODFLOW will reduce the amount that can be pumped from a cell as the cell's head approaches the bottom of the cell (according to the setting of the PHIRAMP parameter in the WEL package). If the setting (in General, Basic Parameters) for "MODFLOW Pumping if Dry or Inactive Cells" is "Do not reapportion pumping from dry or inactive cells," WEAP will reduce groundwater pumping by demand sites and catchments from these drying cells accordingly. This will result in Unmet Demands, and will be included in the MODFLOW "Pumping Reduction" reports.

- Data View:
- Bookmarks: You can bookmark up to 9 branches on the Data View tree, so that you can instantly jump to their location. To set a bookmark, select the branch on the tree and press Shift-Control-#, where # is a number from 1-9. To jump to a previously bookmarked branch, press Control-#. You can also access these functions on the Tree, Bookmarks menu, which also lets you clear all bookmarks, and copy the current list to the Windows clipboard.
- Climate results: Expressions can now reference climate results, such as Snow Depth, in models with climate data at the sub-catchment level.

- Calculations and Results View:
- Enhanced results on map: Display results on the map for any polygon shapefile, including the catchment layer that WEAP's automatic catchment delineation creates.
- Results View graphs are faster to display, especially for charts with many data points.
- Fixed bug in Runoff use for irrigation: For catchments that used "Irrigation Use of Runoff," WEAP was erroneously including a fraction of infiltration to groundwater on the "Runoff Used for Irrigation" line in the Demand Site Inflows and Outflows report. Also, WEAP wasn't handling the Runoff Used for Irrigation correctly for catchments that didn’t have any transmission links (relying only on runoff for irrigation).
- Fixed bug in MABIA ETActual result: When WEAP reported the result for ETActual, it was not including direct evaporation from irrigation lost to evaporation. (This is different from evaporation from bare soil from irrigation.)
- PEST: PEST can now use snow gauge data to calibrate models with climate data at the sub-catchment level.

- Application Programming Interface (API):
- WEAPArea.Backup(BackupFolder, IncludeResults): Backup the area to a .WEAP file in the specified BackupFolder. Optionally include results.
- WEAPFavorite.Delete: Delete the favorite
- WEAPFavorite.Folder: Get the name of the folder the favorite is in. If it is not in a folder, it returns an empty string. Read only.
- WEAPFavorite.Note: Get or set the favorite's note.
- WEAPBranch.PriorityOnTransmissionLink: Get or set whether the demand priority is entered on the transmission link. If not, the demand priority will be entered on the demand site or catchment, and the supply preference will be entered on the transmission link. Can be used only on Demand Sites, Catchments or Transmission Link branches. When used on a Transmission Link, it will set PriorityOnTransmissionLink for the Demand Site or Catchment to which the Transmission Link goes.
- WEAP.CreateLink: You can now create multiple transmission links between the same source and destination.

- Miscellaneous:
- Default Water Use Rate unit: The unit for Annual Water Use Rate for new demand sites and new demand branches will be the unit as set in General, Units, Default Water Use Rate.
- Translations: Improved translations for Portuguese and Turkish.
