Preliminary study of coastal circulation cells in the coastal area of Kendal, Indonesia

The objective of this study was to recognise the hydrodynamic pattern of sea surface current to find the potential of coastal circulation cells in Kendal coastal area. The initial identification of coastal circulation cells in this study used the modification of the band ratio method. Further identification related to the availability of coastal circulation cells utilise the results of aerial photography as a process of detailed validation and has never been done before. The results showed that there was a similar potential of coastal circulation cells in different seasons. In detail, the coastal circulation cells obtained the suspension of sediment, with also the potential of nutrient and alga, namely Rhodophyta Sp. Considered by the colour shown in the photograph of UAV.
