  "account": "Long-term coastal dune monitoring surveys on the Long Beach Peninsula, Washington have revealed that shoreline change rate is the primary driver of alongshore variability in foredune evolution. Beach slope and sediment grain size also play significant secondary roles. These findings, combined with a multi-decadal field dataset, create a quantitative framework linking shoreline behavior to dune development over decades. This insight into large-scale sediment-dune coupling in progradational coastal systems has crucial applied implications. It can aid in coastal hazard assessments, guide dune management strategies, and help predict risks to coastal communities. Identifying shoreline change rate as a leading indicator provides a practical metric for forecasting future dune behavior. The study emphasizes the critical importance of long-term monitoring, as such multi-decadal datasets are rare globally and essential for detecting trends, validating models, and advancing our understanding of coastal processes. Continued investment in sustained coastal observations is vital to support both scientific research and its practical application in effective coastal management.",
