11.4. Version 2020a (released on 14 May 2020)#

Note

In a future release, we will ONLY deliver SUEWS along with SuPy as a command line tool suews-run: release of standalone SUEWS binaries will be stopped to ease our maintenance load and to facilitate rapid developments. Users will need to have Python 3.6+ to install SuPy:

python3 -m pip install -U supy

However, as the source code of SUEWS are public, users can feel free to compile standalone binaries for platforms of their own interests.

Improvement
1. A ponding water scheme is added in the automatic irrigation calculation; useful when a certain depth of ponding water to maintain in irrigation (e.g., flooding irrigation in rice crop-field).
2. Irrigation fraction can be specified for all surfaces (previously only available for vegetated surfaces)
3. A U-shape approach for calculating HDD/CDD is introduced to account for a wide comfort zone between heating and cooling critical temperatures.
Changes
1. A new RoughLenHeatMethod option 5: adaptively choose option 1 for fully pervious surface or 2 otherwise (if any impervious surface exists).
2. A new column H_maintain is added in SUEWS_Irrigation.txt to set ponding water depth.
3. New columns to specify irrigation fractions for non-vegetated surfaces in SUEWS_SiteSelect.txt.
4. A new scheme option BaseTMethod in RunControl.nml to set calculation scheme for HDD/CDD.
Fix

NONE.
Known issues
1. Wind direction is not currently downscaled so non -999 values will cause an error.
