Appendix 6.2 Wave Forecast

(1) Methodology of Wave Analysis

Waves inducing to the objective site can be classified as Figure A6.2-1 shows, i) waves

generated in South Pacific Ocean, ii) waves generated in New Georgia Sound. Waves generated

in South Pacific are coming from Indispensable Strait located between Santa Isabel Island and

Malaita Island and arrive to the site (Offshore of Honiara Port) being reflected by the shelter

consisted of Florida Islands. While, the waves generated in New Georgia Sound arrive to the

site directly. The waves to arrive to the offshore of Honiara Port were obtained by combining

these two waves. In this report, each normal waves and extreme waves (design wave) were

analyzed by this methodology.

The analysis flow is shown in Figure A6.2-2.

The wave generated in South Pacific Ocean was forecasted using “One Point Spectrum

Method”. This is the simple wave forecasting method adopting wave irregularity in its

generation, development and propagation of wind waves and swells to forecast waves on the

computational grid point stretched radially from the site. Figure A6.2-3 shows the locations of

the site and grid points to be used for the “One Point Spectrum Method”.

Figure A6.2-3 Location of Site and Forecasting Grid Point

While, waves generated in New Georgia Sound were forecasted using “SMB Method”.

This method is the one to obtain wave sizes from the data of wind direction, wind speed and fetch

per target wind direction. The fetch was used with the calculation of effective fetch by Saville

considering the depth of fetch and the change of wind direction. Figure A6.2-4 is the calculation

example of fetch used for the waves generated in New Georgia Sound (wave direction in this

figure is NW) and Table A6.2-1 shows the list of fetch. The maximum value of the fetch of the

waves generated in New Georgia Sound is 103km to NNW direction.

Table A6.2-1 Effective Fetch for Waves Generated in New Georgia Sound

(2) Result of Forecasting of Normal Wave (Offshore of Honiara Port)

1) Waves generated in South Pacific Ocean

The forecasting of waves generated in South Pacific Ocean was made from the planar data of

wind of South Pacific Ocean (Data of Japan Meteorological Agency) using “One Point Spectrum

Method”. The period for forecasting is 5 years from 2002 to 2006. With the calculation result,

the Wave Frequency Table of Indispensable Strait is shown in Table A6.2-3 and A6.2-4.

ESE waves which the frequency ratio of wind direction is high are dominated occupying

around 56% of the total and NNE and NE follow in order. The maximum wave height is about

3.5m and the period is distributed around 4 to 10 seconds however, 6 to 9 seconds is the highest

frequency ratio. In the full year, the frequency ratio of 1m, 2m and 3m wave height are 38.6%,

4.3% and 0.2% respectively.

Concerning this wave, the deformation calculation of waves coming into Indispensable Strait

was made using the method to solve the energy balance equation. The example of deformation

calculation is shown in Figure A6.2-5. The wave period in the wave deformation calculation has

set at 8 seconds from the frequency table of wave forecasted. With the calculation result, wave

height ratio and incident wave direction in the offshore of Honiara port are shown in Table

A6.2-2.

Table A6.2-2 Result of Wave Deformation Calculation (Invading Waves to Indispensable Strait)

2) Waves Generated in New Georgia Sound

From the time series data of wind in the objective site (Data of Japan Meteorological

Agency), the waves generated in New Georgia Sound and arriving to the offshore of Honiara port

was forecasted using “SMB method”. The forecasted result is as shown in Table A6.2-5 and

A6.2-7. The wave directions are distributed widely with the range of WNW-N-E. Although

the wind frequency ratio is high with the range of ESE-S-W, the frequency ratio of high waves

becomes small due to the short distance to opposite shore. The period is distributed from 0 to 5

sec. and it is shorter period in comparison with the waves generated in South Pacific Ocean. In

the full year, the frequency ratios more than 1m, 1.5m and 2m wave height are 3.3%, 0.9% and

0.3% respectively.

3) Combination of Waves Generated in South Pacific Ocean and Waves Generated in New

Georgia Sound

Waves have been combined using energy combination method for the wave height and

Tanimoto & Kimura method for the period (Report Vol.25, No.2 of Port and Airport Research

Institute) The wave direction of combined waves adopted the wave direction of higher wave

height out of two combined waves. With the calculation result, the wave frequency table is

shown in Table A6.2-7and A6.2-8 and the wave direction distribution is shown in Figure A6.2-6.

The wave directions are distributed widely with the range of WNW-N-E however, the

frequency ratio is high with ENE and NNE. This is considered the influence of waves generated

in South Pacific Ocean and invaded to the strait and its wave height is relatively small. While,

waves from WNW to NNW are considered to be generated in New Georgia Sound, and these

waves frequency ratio is about 11.6% in total. Comparatively, the frequency ratio of high waves is

high and the maximum reached to about 3.2m. Although, the period is widely distributed, the

period of wave height more than 0.5m is around 3 to 10 seconds and the one more than 1.0m is

about 3 to 7 seconds. In the full year, the frequency ratios more than 0.5m, 1m, 1.5m and 2m

wave height are 14.2%, 4.0%, 1.1% and 0.5% respectively. In view of season, high waves are

occurred more in December to May.

Figure A6.2-6 Wave Direction Distribution Off Honiara Port

(Full Year from 2002 to 2006)

(3) Forecasting of Storm Waves (Design Wave)

Objective site is affected by cyclone waves generated in South Pacific Ocean. Here, wave

at the time of cyclone was studied using the same method with wave analysis of normal wave.

Figure A6.2-7 shows the cyclone routes that consider to be affected a lot to the objective site

out of the cyclones passed around Solomon Islands from the year of 1945 to 2011. Cyclone is

generated and developed at the sea of 5 degree south latitude and southward and it mainly makes

progress toward south. Solomon Islands is located at around 8 to 10 degrees south latitude and the

cyclone is under developed in this water area and is considered to be in the run up to the

developed wave. However, the actual cyclone routes vary widely like some cyclone goes to SW

direction and the others go to SE to E direction.

1) Waves Generated in South Pacific Ocean

Waves coming to Indispensable Strait were forecasted using “One Point Spectrum Method”.

Wave forecasting was made selecting cyclone in May through June, 1972 (No. 7231) and the one

in November, 1996 (No. 9606) that are considered to be heavily affected to objective site out of

the cyclones shown in Figure A6.2-7. The result of forecasting is shown in Figure A6.2-8 and

A6.2-9. The maximum wave height was 5.53m, the period was 9.68 seconds and the wave

direction was NNW. And, the wind condition around objective site was forecasted as the wind

direction is N to NNW, the wind speed is about 25m/s and the duration is around 3 hours.

2) Waves Generated in New Georgia Sound

Waves in New Georgia Sound were forecasted from these cyclones. The wind direction

with the maximum wind speed at the time of above cyclone is N to NW, in the meantime the

direction from the offshore of Honiara where is objective point to New Georgia Sound is WNW

to NW. Here, taking a risky side into the consideration, the wind direction to New Georgia and

the one at the time of cyclone become identical. The maximum fetch in New Georgia Sound is

about 400 km. And, the maximum wind speed is 25m/sec. and the maximum duration time is 3

hours at the time of cyclone. With these results, the maximum wave at the time of cyclone is

obtained as the wave height: 3.18m and the period: 6.02sec. by using SMB method.

3) Combining Waves Generated in South Pacific Ocean and New Georgia Sound

In the same manner with normal wave, when combining invading waves to Indispensable

Strait that is generated in South Pacific Ocean and the waves generated in New Georgia Sound,

the result is as per Table A6.2-9. Table A6.2-10 shows the design waves in the offshore of

Honiara Port based on these results. The wind direction is set as NW to N considering cyclone

routes, distances to coast in New Georgia Sound and the positional relationship between Florida

Island and the objective point.

4) Calculation of design wave in berth front

Wave deformation calculation in shallow water area was made for the wave shown in Table

A6.2-10 and obtained the design wave in front of container yard berth of Honiara Port. The

wave deformation calculation was made using the method to solve energy balance equation.

This calculation method is the one to be able to artificially adopt the diffracted phenomena of

irregular waves by making wharf or island to absorb energy as land. With the calculation result,

the wave height ratio, invading wave direction and etc. can be obtained at the each grid point in

the calculation target domain.

Figure A6.2-10 shows the calculation target domain of deformation calculation. Like this,

the calculation domain is about 2.5km both in East & West and North & South and the grid

distances are all 50m. As the example, Figure A6.2-11 shows the calculation result of wave

direction N. And Table A6.2-11 shows the result of wave size (equivalent deep-water wave

height, invading wave direction) in front of berth. The equivalent deep-water wave height

becomes the most as 2.78m in case of the direction of deep-water wave N and the invading wave

direction becomes N25.4°E (the invading angle to berth is about 65°)

Appendix 6.3 Traffic Observation Survey around Honiara Port

A 6.3.1 Outlines of the Observation Survey

Point Cruz is the central area in Honiara City and Mendana Avenue is the only main road

from there to east- and west-ward. Port-related vehicles from Mendana Avenue go to the port area

mainly through Commonwealth Street. The objective of the Traffic Observation Survey is to

find out the share of the port-related vehicles in the traffic volume at Mendana Avenue.

Observation Survey was carried out for 12 hours (07:00~19:00) for a week (from March 25

(Mon) toMarch 31 (Sun). It was Easter Holidays for 4 days from March 28 to April 1.

Figure A6.3.1-1, 2 show the Observation Points and Typical Road Section of Mendana

Avenue, respectively. Observation results are as shown below.
