Boundary and land cover changes in selected islands of Kelantan Delta

Abstract

Boundary and land cover changes in Kelantan Delta islands dominated by several factors such as strong wind, wave action, tidal period and sediment movement. Kelantan Delta land cover in year 1966 is covered 72.4030 hectare and changed to 159.7073 hectare in year 1995 and 134.3301 hectare in year 2004. The changes also reported for land use in Kelantan Delta islands where it is covered 16.0326 hectare in year 1966, 97.9946 hectare in year 1995 and 75.8725 hectare in year 2004. The drastic changes caused in year 1995 for both land cover and land use are because of big flood event that occurred in 197 5. A lot of seedling and sediment movement became very active during the flood event toward contributed for vegetation widely in Kelantan Delta. This process is naturally occurred.
