Abstract
Beach and delta areas are dynamic physical features with changes occurring at many spatial and temporal scales due to both general and catastrophic events. Geomorphic changes such as temporal and periodic changes in riverbeds and coasts are common events in all deltaic areas. The Hendijan river basin is located in southwest of Iran, close to the city of Hendijan and many villages and rural settlements. It is therefore necessary to detect and identify the geomorphic changes in this area. Through the use of Landsat TM and ETM data and topographic maps, changes of geomorphic features, such as riverbed and shoreline migration, Sebkhas, alluvial terraces, meanders and old, dry rivers were detected and identified. Band differencing, principal component analysis (PCA) and Fuzzy logic were used to derive the change map of the study area.

The results of this study show that an approximate area of 82 km2 has become filled with sediment along the coast during a period of 48 years and the shoreline has migrated over 4 km into the Persian Gulf.
