Coastal change on sandy shores occurs at a variety of spatial and temporal scales. Gaining knowledge of beach change processes increases our ability to manage coastal erosion risks that affect the growing population living in coastal areas. This study focuses on detecting and analyzing historical changes in the shoreline position of Zemmouri Bay (Northern Algeria) between 1957 and 2017. The evolution of the coastline along the bay was studied from aerial photographs (1957, 1957, 1973, and 1988), google earth satellite images (2006, 2011, and 2016), and DGPS (Differential Global Positioning System) topographic surveys of 2012, 2015 and 2017. The correction of aerial photographs and satellite images was performed using remote sensing tools. The study area was divided into six sectors to achieve our objective. Then, net rates of change in shoreline position over time were calculated using several statistical methods: End Point Rates (EPR), Linear Regression Rates (LRR), and Weighted Linear Regression (WLR). These changes were measured for several time intervals and over a global period (1957e2017). The results revealed significant differences in shoreline position over the past 60 years, mainly on both sides of the Isser Wadi. The most observed coastline retreat is located in the eastern part of the coast, where the rate of change has reached -1.25m/year (Mazer Beach East), while the retreat of the coastline was above -1m/year in the center of the bay and -0.50 m/year towards the west. Over a mid-century period, the coast has experienced an overall average net rate of change equal to -1.35m/year. This coastline retreat is due to the combined action of the cumulative effects of the climate on the coast and various human activities on the coastal strip of Zemmouri. [ABSTRACT FROM AUTHOR]
