Floodplain inundation in the Murray-Darling Basin under current and future climate conditions.

ABSTRACT: Predicting floodplain inundation under a changing climate is essential for adaptive management of water resources and ecosystems worldwide. This study presents a framework combining satellite observations and hydrological modeling to explore changes in floodplain inundation. We examine variability, trends, and frequency of inundation across the Murray-Darling Basin (MDB), Australia's largest river system, over the past 35 years (1988-2022). Our analysis shows that annual maximum 30-day runoff is a primary hydrological factor influencing floodplain inundation. Using this metric as a proxy, we found that floodplain inundation, if driven solely by hydroclimate conditions, would have been more frequent in the recent decades (1988-2022) compared to the century-long baseline (1900-2022), especia
