Soil and river water salinity dynamics in coastal Bangladesh.

ABSTRACT: Changes in soil and water salinity pose critical challenges to agriculture, water management, and livelihoods in deltaic environments globally, and particularly in the densely populated Asian mega-deltas. Using observations from 24 stations over nearly two decades (2004-2022) in the Ganges-Brahmaputra-Meghna delta of Bangladesh, our scientific study examined the influences of seasonal weather and climate conditions, tropical cyclones, and hydrology on the seasonal variability in soil and river water salinity. We applied statistical analyses including cross-correlation, seasonal-trend decomposition, and wavelet analysis to explore the spatiotemporal dynamics of soil and river water salinity. We developed statistical models to assess how hydrological, meteorological, and climatic factors exp
