Data

Data was sourced from the channel coastal observatory

Wind data was collected above a threshold of 15m/s

Wave data collected in the same way with a 2m threshold

Data only from one source


Contents

Looe wave rider buoy

Position – 3Km off the coast

10 metres of water to CD

Tidal Range = 4m

Measures every 10 mins

Measure all types of data


Contents

Analysis of wave data

Wave data – radar charts

Used to determine predominant wave direction


Contents

Analysis of wind data

MIKE 21

What is MIKE 21?

Why was it needed?

What did it model?

How was it modelled?


Contents

MIKE 21 – Boundary conditions

Bathymetry

Waves at 10km offshore

Wave model used - JONSWAP


Contents

MIKE 21 - Results


What process was used

Height + Period at buoy

Height + Period at Millendreath

How were the results validated

Contents

Limiting wave height inside marina


What method was used

Wave length calculation

Goda graph to give k’ = 0.075

Worst case wave height at entrance

Using k’ gives height inside of 0.3m to one decimal point

Marina – Layout (Considerations)

Allocation of Berth sizes

Pontoon Layout

Road access

Marina - Calculations

• Finger length – minimum length of 0.75L.

• Finger widths – taken from code of practice

• Single berths – width between fingers:

– up to 20m: B + 1.5m

– 21m +: B + 2m

• Double berths – width between fingers:

– Up to 20m: B1+B2 + 2m

– 21m +: B1+B2 + 3m

• Fairway length – 1.5 x L of the longest boat
