Description
Using multitemporal Landsat MSS (Multispectral Scanner System)/TM (Thematic Mapper)/ETM+ (Enhanced Thematic Mapper Plus) data, changes in the beach of Enshunada around the Tenryugawa estuary were evaluated. The modified normalized difference water index (MNDWI) and the normalized difference vegetation index (NDVI) were calculated for each image. Using those indices, each image was classified into three categories: water, soil and built-up, and vegetation. Comparing among classified images at the high or low tidal level, changes in the beach were evaluate. The result shows that the beaches around the Tenryugawa estuary retreated landward. On the other hand, the Nakatajima beach extended seaward. This shows that offshore breakwaters which have been constructed since 1961 are probably effective.
