basin_parms_dpm.f
Establish the basin parameters.
Establish the basin parameters for the model and write input parameters to a file. The parameters are based on the data-input subroutine of Bauer and Vaccaro (1987).
July, 2004
hru_elev
Mean elevation for each HRU, in feet.
hru_area
HRU area, in square miles.
hru_slope
HRU slope as vertical feet/horizontal feet, in decimal percent * 100 (0-90).
hru_aspect
HRU aspect in degrees from north: 0-360, in degrees.
hru_ylat
HRU Y-location of centroid, latitude or state plane, in feet.
hru_xlong
HRU X-location of centroid, longitude or state plane, in feet.
hru_soil
HRU soil type, no units.
cov_type
HRU cover type: land use type, from 1-31, no units.
hru_appld
Application rate of irrigation water for HRU, in inches.
hru_irr_methd
Irrigation method for HRU: 0=above canopy, 1=all other
hru_mon_ppt
Mean monthly precipitation for each HRU, in inches.
wght
HRU area as fraction of total area, as a fraction.

The module declares and initializes the parameters for the basin. The parameters are then written to a file. The basin area, a calculated parameter, is computed as the sum of the areas of the HRUs. The variable wght is then calculated as
wght(i) = hru_area(i) / basin_area,
where
nhru is the number of HRUs,
i is the index for the HRU, with i from 1 to nhru,
wght is the HRU area as fraction of total area,
hru_area is the area of a HRU, and
basin_area is the total area of the basin.
