Peramu Beach Profile Analysis
4.4.4 Peramu beach (Station 4)
Peramu beach is located betweenPerkampunganPeramuMaju and KampungPeramu Hulu, approximately 2 km from Kuantan city. The station is covered by thick Casuarinas plants and visible to some extent in the backshore area.
Figure 4.10 exemplifies the series of beach morphology in 100 m wide at this station. Generally, the beach surface appeared to be constant with gentle gradient as no remarkable substantial changes perceived. The beach contour after 20 m distance from benchmark seems to be smooth and flat in shape.
The trend of beach profile changes at this site shows very few changes as for the entire period of study (Figure 4.11). The profiles can be deemed as stable where there is slight variation over the sequence of survey. Steeper gradient was observed in the upper intertidal zone (HT) with a prominent convex profile’s appearance. Lower (LT) and middle intertidal (MT) zones are flat and featureless, which indicates a strong dissipative domain during low tide condition. …show more content…
This is in conjunction with the result of LEO clarified that observed wave height were reasonably low with maximum value of 0.4 m. Most current directed northwestward and southwestward at speed ranged between 0.8 – 27.9 m/min (Table 4.5).
