Coastal tidal inlets and barrier islands are important for protecting coastlines. This report looks at how these areas change over time and how we can manage them sustainably. By studying sediment movement and long-term processes like sea-level rise and climate change, we can better understand how to protect these valuable coastal features. It's crucial to consider the effects of human activities, like mining sand from ebb-tidal deltas, on the health of these systems. Long-term studies are needed to see how all these factors interact and affect the overall sustainability of coastal areas.
