3.2.5. SUEWS_NonVeg.txt#
SUEWS_NonVeg.txt specifies the characteristics for the non-vegetated
surface cover types (Paved, Bldgs, BSoil) by linking codes in column 1
of SUEWS_NonVeg.txt to the codes specified in SUEWS_SiteSelect.txt
(Code_Paved, Code_Bldgs, Code_BSoil). Each row should correspond to a
particular surface type. For suggestions on how to complete this table,
see: Typical Values.
