Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3515-3545, December 2022., 2022 Glacial geomorphology and postglacial landforms, derived from LiDAR‐based digital terrain models, together with radiocarbon‐dated sediment sequences, form the basis for landscape reconstruction spanning c. 2000 years (10,500–8500 cal. bp). After formation of streamlined terrain and ribbed moraine tracts followed intense glaciofluvial activity at ...

Earth, Planets and Space, 2021 We propose a new waveform inversion method to estimate the 2D S-wave velocity structure of deep sedimentary layers using broadband Love waves. As a preprocessing operation in our inversion scheme, we decompose earthquake observation records into velocity

Particle saltation trajectories in supercritical open channel flows: Roughness effect
Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3588-3610, December 2022., 2022 This study investigates single particle trajectories in supercritical open channel flows under different hydraulic and roughness conditions. Therefore, it helps to get a better understanding on the mechanics and prediction of bedrock incision and hydro‐abrasion occurring in steep bedrock rivers and hydraulic structures.

Engineering Geology, 2023 In probabilistic inversion of geophysical data, one must describe the expected noise in the system, and any prior information. In a geoscience context, prior information can provide a quantitative description of the expected spatial variability and correlations of the geology.

Earth Surface Processes and Landforms, Volume 48, Issue 1, Page 215-229, January 2023., 2023 This paper uses a numerical landscape evolution model to reconstruct the topographic history of Madagascar since the Late Cretaceous. The model is optimised by balancing the volumes of onshore erosion and offshore sedimentation; the former is predicted with erosion laws and based on uplift history inferred from elevated planation surfaces.

Geology-geophysics integrated inversion in Mount Isa South, Queensland
, 2023 Taking advantage of all available information including geological and geophysical datasets is important to understand the subsurface. Integration of geological and geophysical datasets is commonly limited to the interpretation of areaspecific case studies and has seldom been addressed by automated techniques. Considering, the geometry of rock units as

Elastic waveform inversion in the frequency domain for an application in mechanized tunneling [PDF]
arXiv, 2022 The excavation process in mechanized tunneling can be improved by reconnaissance of the geology ahead. A nondestructive exploration can be achieved in means of seismic imaging. A full waveform inversion approach, which works in the frequency domain, is investigated for the application in tunneling.

Earth, Planets and Space, 2020 Prospective Proterozoic units in the southern Mount Isa Province are concealed by a poorly defined extent of younger basin cover, leading to poor exploration success.

Geoarchaeology, Volume 38, Issue 1, Page 57-75, January/February 2023., 2023 Abstract Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological samples from Egypt, modern geoscientific studies in the Nile Delta lack the possibility of dating the investigated ...

Seismic Inverse Modeling Method based on Generative Adversarial Network [PDF]
arXiv, 2021 Seismic inverse modeling is a common method in reservoir prediction and it plays a vital role in the exploration and development of oil and gas. Conventional seismic inversion method is difficult to combine with complicated and abstract knowledge on geological mode and its uncertainty is difficult to be assessed.
