Coastal erosion and stream flow dynamics: historical analysis and forecasting shoreline changes in the Yeşilırmak delta
This study examined the historical shoreline evolution and predicted future changes for the Yeşilırmak Delta in Turkey, spanning from 1985 to 2024, with projections extending to 2044. The Yeşilırmak Delta has undergone substantial erosion due to a combination of factors, including sea-level rise and reduced sediment transport resulting from dam constructions along the river. The temporal shoreline changes were analyzed using Landsat satellite imagery and the Digital Shoreline Analysis System (DSAS), employing the Modified Normalized Difference Water Index (MNDWI) and object-based classification methods. In addition to the shoreline analysis, a comprehensive examination of streamflow data from 1985 to 2020 was conducted to assess the reduction in sediment transport. This analysis revealed a significant decline in flow rates at key stations, which exhibited a strong correlation with increased coastal erosion. The study forecasts future shoreline changes for 2034 and 2044, emphasizing the pressing need for effective coastal and water resource management strategies to mitigate further degradation and safeguard this vital ecosystem.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
