Impact of Climate Change on Landforms, River Basin Hydrology, and Flood Frequency

Climate change research has increasingly highlighted how geomorphological processes and river basin hydrology are undergoing profound transformations due to rising global temperatures and shifts in precipitation patterns. These environmental changes are altering the fundamental processes that shape landscapes, including weathering, erosion, sediment transport, and deposition, which in turn influence the evolution of landforms. The responsiveness of river basins to climate variations is evident through modified runoff patterns, streamflow regimes, and groundwater recharge dynamics. Recent studies document a marked increase in the frequency and intensity of floods, alongside growing evidence of non-stationarity in flood behavior, posing urgent questions about floodplain stability, water infrastructure resilience, and landscape management. While studies have mapped out regional responses and certain trends, considerable gaps remain in linking these geomorphic and hydrological shifts to climatic drivers across scales and settings. Addressing these uncertainties is crucial, given the pressing need for robust risk assessment and sustainable management practices under accelerating climate change.This Research Topic aims to advance the understanding of how climate change drives the evolution of landforms, alters river basin hydrology, and affects flood frequency and magnitude. By investigating the connections between climate-induced variations in temperature and precipitation and their impacts on hydrological processes—such as surface runoff, flow variability, and peak discharge—the research seeks to unravel the consequences for channel morphology, floodplain dynamics, and sediment movement. Additionally, by integrating diverse data sources including long-term hydrometeorological records, climate projections, and statistical analyses, this initiative aspires to identify patterns of flood non-stationarity and project future flood risks under varying climate scenarios. Ultimately, the aim is to inform and enhance flood modeling, climate-resilient planning, and the development of long-term adaptation and mitigation strategies for river basin systems.The scope of this Research Topic includes both the physical and process-oriented dimensions of climate-induced transformations in riverine and terrestrial environments. It is limited to perspectives that directly address the interplay between climate variability, geomorphology, and hydrology at river basin and sub-basin scales. To gather further insights in this area, we welcome articles addressing, but not limited to, the following themes:• Climate-driven changes in landform evolution and geomorphological processes• Hydrological impacts of altered precipitation and temperature on river basins• Trends and non-stationarity in flood frequency, magnitude, and timing• Sediment transport, channel morphology, and river-floodplain interactions under changing climates• Integration of field data, remote sensing, modeling, and paleoclimate evidence• Implications for basin-scale risk assessment, landscape sustainability, and adaptation planning• Synergies and feedbacks involving climate change, land-use dynamics, and human interventionsAppendix: We welcome both original research articles and comprehensive review papers. Contributions should clearly describe methodologies, data sources, scales of analysis, and implications for management and adaptation.
