Alluvial geomorphology is the study of landforms and processes associated with the deposition and erosion of sediment in riverine and floodplain environments. It examines the interactions between water flow, sediment transport, and landscape evolution, focusing on how these factors shape the physical characteristics of alluvial systems over time.

Key research themes

1. How can digital elevation models (DEMs) and GIS algorithms be utilized to accurately delineate and analyze alluvial fan geomorphology on Earth and extraterrestrial surfaces?

This research area focuses on the development and application of remote sensing techniques, particularly DEM analysis and GIS-based algorithms, to identify, map, and characterize alluvial fans and related fluvial geomorphic features. Accurate delineation of alluvial fans assists in understanding sediment transport dynamics, hazard assessment, and planetary geomorphology comparisons, including on Mars. Automated or semi-automated methods are crucial to handle large spatial datasets and to enable consistent, reproducible analyses across terrestrial and planetary surfaces.

Key finding: Introduced a semi-automated GIS algorithm integrating spatial analysis of drainage networks, slope, and curvature from DEMs to accurately map alluvial fan apexes and deposits on Earth and Mars, demonstrating high accuracy in... Read more
Key finding: Compared two globally available multiresolution DEM products (MERIT and FABDEM) for watershed delineation and morphometric analysis, assessing differences in derivable parameters essential for alluvial geomorphology studies.... Read more
Key finding: Reviewed fluvial and fluvial-like channelized features on Earth and planetary bodies, emphasizing the role of high-resolution remote sensing and analogy with terrestrial alluvial landforms in interpreting morphological... Read more

2. What are the sedimentological and morphodynamic processes governing the formation, architecture, and evolution of alluvial and fluvial fans in tectonically and climatically diverse settings?

This theme investigates the physical and depositional mechanisms shaping alluvial fan systems, focusing on sediment transport pathways, depositional processes, autogenic lobe switching, and their responses to tectonic, climatic, and base-level changes. Understanding the morphodynamics of alluvial fans informs on catchment-basin interactions, landscape evolution, and stratigraphic record formation over different timescales and environmental conditions.

Key finding: Established that alluvial and fluvial fans form dominantly where laterally confined catchments transition to open basins, controlled by autogenic sediment transport path switching and depositional lobe formation. The paper... Read more
Key finding: Formulated a systematic morphodynamic framework describing erosional, depositional, and equilibrium fluvial sedimentary patterns arising from free-boundary instabilities and hydrologic forcing. The work elucidated mechanisms... Read more
Key finding: Documented fluvial sedimentology and alluvial architecture of volcaniclastic deposits, revealing spatial variability in channels and floodplain facies controlled by proximal-distal basin position and tectonics. The study... Read more

3. How do tectonic activity, climatic fluctuations, and sediment supply interplay to control the stratigraphy, architecture, and evolution of alluvial depositional systems and paleoenvironments?

This area explores the influence of tectonics, climate variability, and sediment provenance on alluvial fan and fluvial system development, including accommodation space changes, sedimentation rates, paleosol formation, and landscape tilting. It integrates stratigraphic, geomorphic, and geochronological data to reconstruct paleoenvironmental conditions and understand alluvial system responses to external forcing over geological timescales.

Key finding: Identified four morphostratigraphic phases in the Sone megafan evolution driven by climatic oscillations and basement fault activity. Demonstrated that basement fault tilting controls sediment redistribution and that... Read more
Key finding: Characterized a 45 m-thick alluvial succession with well-developed composite paleosols reflecting episodic sediment aggradation and subaerial exposure under semi-arid climatic conditions influenced by local tectonics and... Read more
Key finding: Discussed how the geologic history of planetary surfaces, including tectonic settings and volatile cycling, influences fluvial landform formation. Highlighted the fundamental epistemological challenges in attributing surface... Read more
