The Ranchería River delta, located in Riohacha, Colombia, exemplifies the complex dynamics of coastal systems influenced by environmental and anthropogenic factors. This study analyzes spatial temporal evolution delta’s shoreline over past two decades (2003–2023) using Google Earth imagery, Digital Shoreline Analysis System (DSAS) within a GIS environment, statistical methods such as ANOVA Tukey’s test. Satellite images from 2003 to 2023 were processed evaluate through metrics like Net Movement (NSM) Linear Regression Rate (LRR). results reveal predominant trend accretion, with values reaching up 260 m NSM, particularly between 2018. However, 2018–2023 period shows shift toward stabilization localized erosion (e.g., NSM ranges 96 32 accretion), significant changes northeastern area (the Santa Rita arm) attributed anthropic natural factors absence mangroves or ongoing human activities). comparison LRR reveals consistent linearity behavior across period, suggesting stable processes during accretion-dominated phases increased variability recent erosion. Variability zones highlights role barriers mitigating findings underscore importance integrating long-term data trends for management emphasize adaptive strategies conserve critical ecosystems while addressing socio-economic needs local communities.
