24-01-2020 - Appeal No. 245 of 2019 - Final Order of Judge Rackemann · 51987.2951.01

Working Notes:
M Design and Fourteen Enterprises Pty Ltd as trustee v Noosa Shire Council -
42 Seaview Terrace, Sunshine Beach



       0.2 metres by 2040,
       0.5 metres by 2070, and
       0.8 metres by 2100.

The adopted sea level rise allowances are consistent with industry practice and will be used for this
assessment. In addition, an allowance of 0.3 metres by the year 2050 will also be considered for this
assessment to coincide with the asset lifespan adopted for the proposed concrete swimming pool.


4.2.    Wave Climate and Design Wave Conditions
Winds acting on the sea surface generate waves known as sea, as the sea waves move out of the
area the wave form becomes more regular and this is known as swell waves.

The wave climate at Sunshine Beach is influenced by both locally wind-generated sea waves and
ocean swell. Sea describes wind generated waves where wind energy is still being transferred to the
ocean. Swell describes wind generated waves that have travelled out of their generating area. Swell
characteristically exhibits smoother, more regular and uniform crests and a longer period than wind
waves. In open coastal areas sea waves generated by local winds are often superimposed on swell
waves.

The wave climate for Sunshine Beach has been previously reported by BMT WBM (2013), “Coastal
Processes Study for the Sunshine Coast” prepared for the Sunshine Coast Regional Council. BMT
WBM (2013) has shown the wave climate for Sunshine Beach is dominated by waves from the east-
southeast direction (refer Figure 3-1)
