This National Topographic Map Series involved the compilation of 3,062 sheets at 1:100,000 scale with contours at 20-metre vertical intervals
and was completed in 1988.
Since the permissible spacing based on soil loss takes into account more of the erosion variables, a vertical interval of 1.7 m as computed in Example 8.1 is preferred.
8.3 On one graph, plot two curves with the slope in percent (0 to 10) on the x axis, and the vertical interval and the horizontal interval for graded terraces on the y axis.
The company chief executive officer, Tony Buckingham, said, 'We are delighted to have encountered excellent oil shows over such a large vertical interval
. This is very encouraging for increasing oil reserves in the Albert Basin and we look forward to undertaking successful production tests later this summer.'
Sub levels were initially developed at 20 m intervals, with drawpoints situated within main footwall extraction haulage levels at 80 m vertical intervals
19, alto f' against tenor f[sharp]) nor unpleasant vertical intervals
(such as in no.
If I understand it correctly, the analyses, based on a technique developed by Victor Pollard, assess the suitability of a particular temperament for a given passage by calculating the deviations of all vertical intervals
from their corresponding just values.
Lag correlations compare the [NO.sub.3-N] concentrations measured in the vertical intervals
in 1990 with those measured in 1985.
All future main level development will be at 180 m vertical intervals
Main levels are to be developed at 50 or 60 m vertical intervals
. To date there are two such levels 240 and 300 m below surface.
