“…From this perspective, Souza et al (2022) did not disregard the works published in the last 30 years, as mentioned by the commenters. Our article came to fill this gap in the literature on the dynamics of PSRD and launch insights on the delta evolution considering the river and modern literature about it and advancing the scientific knowledge about the area.…”

“…Furthermore, in the comments, the authors state that "according to Souza et al (2022), the geomorphological evolution occurs mainly during the Little Ice Age (LIA: ∼1400 -1850 CE)." The commenters use parts from our article to state that Souza et al (2022) considered the PSRD geomorphological evolution that occurred mainly during the LIA.…”

“…From this perspective, the authors of the comments state that " Souza et al (2022) practically disregard the role of relative sea-level behavior in delta evolution, as reinforce the causality between LIA and deltaic progradation." This statement is inconsistent with the discussions driven in the original article because we discussed how the Little Ice Age impacted the PSRD geomorphological dynamics considering mainly the hydrological variations and continent-ocean sedimentary balance.…”

Scientific knowledge advances by the discussions about hypotheses, methods, and results, wherein the contradictory plays a positive role developing new theoretical-methodological approaches. In a positive debate to the progress of the science, the agreements and disagreements must only permeate the scientific scope and based on ethics to be away from the conflicts of interest. From this perspective, after knowing the submission entitled Comments on Souza et al. (2022) “Recent geomorphological changes in the Paraiba do Sul delta, South America East Coast” to the journal Progress in Physical Geography: Earth and Environment (PPG), which addressed several issues concerning to the results published in that article, we wrote this response to clarify the doubts related with the original paper. The comment’s authors focus mainly on the da Rocha et al . (2019), a locally published article that did not fully encompass the complexity of processes and geomorphological dynamics related to the delta evolution. Furthermore, it did not present the parameters used in the geochronological analyses in accordance with the international literature. Finally, the discussions presented in the original article contribute to advances in knowledge about the responses of the Paraíba do Sul delta to the Little Ice Age.

Geomorphological evolution in transitional environments on the eastern coast of Brazil

The morphology of the coastal landscape in transitional environments results from the gradual and complex dynamics of natural processes at different scalarity, capable of elaborating and remodeling the relief. Their arrangements and interactions are reflected in the configuration and evolution of the landscape and waterscape governed by allogenic factors (climate, tectonics and, more recently, anthropogenic) generating autogenic responses in environmental systems. In this sense, several studies have demonstrated the importance of sea level oscillations, sedimentary balance and river‐coastline displacements associated with climate fluctuations during the Quaternary. However, there is still a relative lack of recent research that focuses on the last glacial maximum (LGM) and the Holocene for the eastern Brazilian coast. In this way, the intense morphodynamics between estuarine and deltaic systems could become interpretative keys in the general understanding of these environments worldwide because they are located in a particular context within the connectivity of these geomorphological systems. To investigate these processes between the Jequitinhonha, Pardo and Una Rivers, detailed mapping and geomorphic topographic profiles were carried out using pre‐selected digital elevation models, and fieldworks were carried out on land and water to validate the mappings and to collect samples. Then, they were subjected to geochronological analysis using Optically Stimulated Luminescence and grain size distribution to recognize the depositional age and characterize the surficial cover. It was possible to identify five depositional landscape units: fluvial terraces, fluvial‐marine terraces and three staggered levels of marine terraces. Based on these results, a paleogeographic reconstruction of the evolutionary phases of this eastern sector of Brazil's coast was carried out, chronologically covering the Pleistocene/Holocene transition up to the present. The aim is to understand littoral dynamics as a response to both fluvial adjustments and oscillations of the regional relative sea level.

Rivers represent intricate geomorphological systems that exhibit sensitivity to even subtle base‐level changes. This study examines the geomorphological response of Ribeira de Iguape River, located along the southern coast of São Paulo state, Brazil, to hydrological changes and coastline migration resulting from Holocene climate pulses. Using a multidisciplinary approach, including geomorphological and stratigraphical analyses, optically stimulated luminescence dating, grain‐size analyses, interpretation of satellite images, mapping and reassessment of previous studies, we investigated the potential impacts of these geomorphological dynamics on the river system. Our study reveals two distinct orders of low fluvial terraces, typically inserted no more than 10 m above the average channel discharge, which are geochronologically correlated with the low marine terraces that document the former coastline position at the river mouth, as previously identified in other studies. Such findings indicate a deposition phase when the coastline was stabilised on the inner continent in the Medieval Warm Period, as well as an erosion phase when the coastline migrated seaward during the Little Ice Age. This research contributes to improving our understanding of how rivers can respond to base‐level changes and provides valuable insights into the dynamic interactions between river systems and coastal environments.
