  Because of coastal erosion and accretion, coastal zones are increasingly vulnerable to coastal devastation. Thus, coastal or shoreline calculation is a crucial aspect in manifesting coastal erosion and accretion, and it plays an important role in shoreline morphodynamic research. To investigate previous or present coastline positions or shape, the Digital Shoreline Analysis System (DSAS) can be utilized in HTA (Historical Trend Analysis). We used a diachronic analysis of aerial photographs and satellite images obtained between 1975, 2001 and 2018, as well as a topographic map from 2015, to analyze the changes occurring throughout the research area. The used methodology is based on geometric and radiometric corrections of aerial photographs and satellite images in order to digitize Tyre shoreline by DSAS version 5. This study focuses on the shoreline change detecti.. View More»
