INTRODUCTION
This document contains a selection of results from recent analyses of
the South Uist data. It extends the results previously presented in
WESC (79) DA89 and WESC (81) DA126.
The data on which the presentations are based cover the period August 1980
to August 1981.
Data are presented for three buoys which were positioned at the following
locations.
Deepwater buoy -
Offshore buoy
Inshore buoy II
positioned 057° 17' 48" N
007° 53' 54" W
in 98 m water during the period August 1980 to
August 1981.
positioned 057° 18' 21" N
007° 38' 09" W
in 45 m water (approx) during the period
August 1980 to August 1981.
positioned 057° 19' 36" N
007° 29' 06" W
in 23 m water during the period August 1980
to January 1981.
and
Inshore buoy III - positioned 057° 17' 24" N
007° 29' 09" W
in 25 m water during the period March 1981
to August 1981 .
All positions and depths are approximate as minor variations occur when
buoys are replaced on service visits. Positions are indicated on the
chart in figure 1.
The diagrams which constitute the main body of this report are arranged
in five sections as follows:
1. Waves at the deepwater buoy.
2. Waves at the offshore buoy.
3. Waves at the inshore buoy.
4. Comparisons between deepwater and offshore sites.
5. Comparisons between inshore and offshore sites.
1. Waves at the deepwater buoy
Diagrams under this heading include:
Fig 1.1 Scatter diagram of Hg v Tg Aug 80-Aug 81
Fig 1.2 Scatter diagram showing distribution
of total energy with Hg and Tg Aug 80-Aug 81
Fig 1.3-1.6 Time series of power Aug 80-Aug 81
Fig 1.7-1.10 Time series of Hg Aug 80-Aug 81
Fig 1.11-1.14 Time series of Tg Aug 80-Aug 81
2. Waves at the offshore buoy
Fig 2.1-2.3 Time series of power Aug 80-Aug 81
Fig 2.4-2.6 Time series of Hg Aug 80-Aug 81
Fig 2.7-2.9 Time series of Tg Aug 80-Aug 81
Note: There are no data for the period October 1980 to April 1981, with
the exception of a few values in January and February 1981.
3. Waves at the inshore buoy
Fig 3.1-3.4 Time series of power Aug 80-Aug 81
Fig 3.5-3.8 Time series of Hg Aug 80-Aug 81
Fig 3.9-3.12 Time series of Tg Aug 80-Aug 81
Note; Data from the inshore III position commence at the beginning of
March 1981.
4. Comparisons between deepwater and offshore sites
Fig 4.1-4.8 Scatter plots of offshore against simultaneous deepwater wave power
Superimposed upon each plot is the straight line which results from a major
axis regression analysis performed on each month's data. Note that the
'standard error' quoted in the figures is just the RMS perpendicular distance
of the plotted points to the fitted line and has units of kW/m.
In addition to these monthly comparisons a standard y on x regression analysis
was performed using all the data. Power at the offshore buoy as the independent
variable and power at the deepwater the dependent variable. The results are
set out below.
Slope of regression line 1.23
Intercept 0.29
Standard error of slope 0.01
Standard error of intercept 0.34
Correlation coefficient 0.958
Slope of regression hire constained
to pass through (0,0) 1.24
5. Comparisons between inshore III and offshore sites
Fig 5.1-5.5 Scatter plots of offshore against simultaneous inshore III
wave power
The results of the regression analysis performed on all the data are set
out below.
Slope of regression line 0,75
Intercept 0.37
Standard error of slope 0.01
Standard error of intercept 0.20
Correlation coefficient 0.937
Slope of regression line constained
to pass through (0,0) 0.762
Implications of comparisons
The predicted long-term average power density at the offshore site is
47.8 kW/m and the results of the regression analysis may be used to
scale this figure to form estimates of the long-term average power density
at the deepwater and inshore III sites. The results are:-
Inshore III sites 36.2 ± 0.6 kW/m
Deepwater site 59.2 ± 0.9 kW/m
