3.2. SUEWS Site Information#


  1. We use the following codes for denoting the requirement level of various input variables/parameters for SUEWS throughout this section:


    Parameters which must be supplied and must be specific for the site/grid being run.


    Parameters which must be supplied and must be specific for the site/grid being run (but default values may be ok if these values are not known specifically for the site).


    Parameters that are optional, depending on the model settings in RunControl.nml. Set any parameters that are not used/not known to ‘-999’.


    Codes that are used to link between the input files, which must

    • be specified in the correct way to link the main and sub-reference files (similar to key-value pairs);

    • be integers and unique in column 1 of corresponding input files; and

    • match up with column 1 of the corresponding input file, even if those parameters are not used (in which case set all columns except column 1 to ‘-999’ in the corresponding input file), otherwise the model run will fail.

  2. We use the following codes for denoting the typical land cover/entity types of SUEWS throughout this section:


    Paved surface


    Building surface


    Evergreen trees and shrubs


    Deciduous trees and shrubs


    Grass surface


    Unmanaged land and/or bare soil


    Water surface


    The water that drains freely off the impervious surface


    The water stored in the underlying soil that infiltrates from the pervious surface
