wrain_intcp (nhru)

PRMS Parameter Name(s): wrain_intcp

BAGIS-P Model Toolbox: bagis_p_climate_methods.tbx

BAGIS-P Model Name: Winter_Rain_Intcp

Required DATABIN Layer(s):

• db_cover_type: Landfire_EVT

• db_cover_density: Landfire_EVC_CC

Parameter Description: Gives the mean winter rain interception storage capacity in inches for each hru, using winter rain interception coefficients developed for the SAF-SRM classes of Landfire_evt by George Leavesley.

Methods:

• 1. Weights are assigned to pixels with different COV_TYPE (bare ground: 0%; grass:80%; shrub:70%; deciduous: 60%; coniferous: 100%)

  2. For each pixel: wrain_intcp = db_cover_density x WEIGHTED_COV_TYPE x intcp_wrain (note: all percentage values are converted to decimal numbers)

  3. Calculate the averaged wrain_intcp value for each HRU.
