“…The efficiency of connectivity between river and coastal environments is a ubiquitous framework for the development and evolution of delta systems in different climates, both along wave-dominated and tide-dominated coastlands, which in the last decades are the object of river restoration, especially in urbanized areas (Kondolf and Piégay, 2003; Jain and Tandon, 2010; Fryirs, 2017; Guo et al, 2019; Donadio, 2017; Magdaleno, 2017; Passalacqua, 2017). In this sense, the deltas result from continent-ocean interaction processes occurring in transitional environments (Huggett, 2017; Gani, 2020). Natural or human-induced hydro-sedimentary alterations can result in the responses and complex geomorphological evolution of these environments (e.g., Arnaud-Fassetta, 2000, 2003; Brandolini et al, 2020; De Santis et al, 2018) which often change into estuaries or temporarily closed estuaries in a period of climate change (Houghton, 2015; Masselink et al, 2011; Moser et al, 2012; Stein et al, 2021).…”

The Paraiba do Sul River delta, a South America east coast system, presents deposits recording complex sedimentary dynamics in the deltaic plain during the Little Ice Age (LIA). The use of optically stimulated luminescence (OSL) dating, sediment grain-size characterization, and morpho-chronological analysis showed that from ∼450 to 100years (LIA period), both in lower to upper deltaic plain, remodeling occurred in conjunction with the coastline regression. The freshwater and sediment influx increases due to the moisture enhancements during the LIA resulted in the intensification of the fluvial dynamic, channel downcutting on the marine terrace, and sedimentary environments remodeling. Further, the base-level changes occasioned by the coastline regression strengthen the geomorphological dynamics associated with the recent changes in the Paraiba do Sul delta. Currently, the coastal erosion problem found in the area seems to reflect the coupling between climate dynamic (rainfall rates decrease) and multiple-scale anthropic intervention. Results show a high sensitivity of humid tropical deltaic systems to short-time climate events, further contribute to broadening discussions on the complexity of this delta system’s morphosedimentary evolution during the Late Holocene.
