2.2.5. 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.
