SOILSERIES hydrology is tabular data that can be used in conjunction
with any of the NATMAP products except NATMAP soilscapes.
SOILSERIES hydrology provides extensive information
on the water regime and hydrology of each soil. This
is the essential dataset for those involved with groundwater modelling
and flow prediction. It has many uses in the environmental sector and
applications in related sectors.

DIMP_UD
999
Depth (cm) to slowly permeable layer - upward diffusion, ie in which
effectively there is no downward percolation of water (Jones 1985,
Robson and Thomasson 1977) - 999 implies NO slowly permeable layer

BYFLOW
N
Bypass flow (Yes/No)
BFI
0.93
Baseflow index. Dimensionless variable (range 0 to 1.0) that expresses
the fraction of the average flow volume represented by the contribution
from groundwater storage
SPR
2
Standard Percentage Run-off. Dimensionless variable (range 0 to 100
%) that represents the percentage of rainfall that causes the short-term
increase in flow at the catchment outlet seen after the storm event
