The coastline changes along Yemen's the Red Sea (Al-muka, Al-khohah, Al-tiaf, Ras Katib and Al- Urji spits) were studied using a series of landsat images (MSS, TM and ETM + , 1972, 1989, 2000, 2006), coupled with geomorphological, sedimentological and meteorological findings. Comparison of satellite images provided a viable means for establishing long-term coastal changes (accretion and erosion) as observed in the studied spits (Al-Urj, Ras Sham, Ras Maemoon, Ras Katib, Al-Mandar, Nukhaylah, Mujamilah, Ras Ashab Abu-Zahr and Mukha). The rate of the spit accretion has the greatest value up to 89 pixel/year corresponding to 72 290 m2/year in Mukha, while the spit erosion shows greatest value up to 131 pixel/year corresponding to 106 404 m2/year in Mujamilab. The patterns of accretion and erosion along the spits depend on the spit direction, natural processes mainly of wave-induced longshore currents, the sediments supply and depth of sea. 展开更多
