covden_sum (nhru)

PRMS Parameter Name(s): covden_sum

BAGIS-P Model Toolbox: bagis_p_vegetation_methods.tbx

BAGIS-P Model Name: Cov_Den_Sum

Required DATABIN Layer(s):

• db_cover_type: NLCD_TreeCover

Parameter Description: This model calculates summer vegetation density within AOI zones. Required inputs are a vegetation cover and zone grid. The vegetation is first reclassified to simplify the landcover - 0 = bare ground, 1 = grass, 2 = shrub, 3 = deciduous trees, 4 = coniferous trees.

Methods:

• 1. Using Raster Calculator, convert db_cov_density to a floating point and divide the output by 100 (to convert % to decimal) to create covDen raster.

  2. Calculate the MEAN density for each HRU using Zonal Statistics as Table.

  3. Set the output value as the parameter value.
