An updated version of the SZ-plugin: from space to space-time data-driven modeling in QGIS
Published: 2025-01-14
Subjects: Geology, Geomorphology, Software Engineering, Statistical Models
The geospatial community usually makes use of GIS environments to handle databases and pre-process their information. Actual analyses, especially data-driven ones, are performed outside GIS platforms. This interrupts the flow of information and the processing chain in a number of I/O operations that inevitably slow down the overall analytical protocols. The first version of the SZ-plugin [...]
Is the Suez Rift in its post-rift phase?
Published: 2025-01-03
Subjects: Earth Sciences, Geology, Geomorphology, Physical Sciences and Mathematics, Tectonics and Structure
Failed rifts are widely assumed to enter post-rift quiescence after termination of intracontinental rifting. However, this remains largely untested and a comprehensive evaluation of the rates and patterns of post-rift tectonic (in)activity is lacking. Our novel, rift-scale geomorphic analysis reveals “post-rift” rifting across the archetypal failed rift of Suez, in Egypt. Stacked topographic [...]
Sea level rise submergence simulations suggest substantial deterioration of Indian River Lagoon ecosystem services by 2050, Florida, U.S.A.
Published: 2025-01-03
Subjects: Climate, Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Geology, Geomorphology, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability, Water Resource Management
The Indian River Lagoon is a 250-km long Estuary of National Significance located along the east central Florida coast of the USA. NOAA tidal records generated at a station located in the central reaches of the estuary indicate sea level rise has accelerated over the past 20 years to an average of 9.6 ± 1.6 mm yr−1 (2003–2022) and it is expected to continue accelerating over the duration of this [...]
Functional regression for space-time prediction of precipitation-induced shallow landslides in South Tyrol, Italy
Published: 2024-12-10
Subjects: Applied Statistics, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geology, Geomorphology, Hydrology, Multivariate Analysis, Statistical Models
Shallow landslides are geomorphic hazards in mountainous terrains across the globe. Their occurrence can be attributed to the interplay of static and dynamic landslide controls. In previous studies, data-driven approaches have been employed to model shallow landslides on a regional scale, focusing on analyzing the spatial aspects and time-varying conditions separately. Still, the joint assessment [...]
Towards centimeter precision SAR-RFID localization
Published: 2024-11-20
Subjects: Engineering, Geomorphology, Physical Sciences and Mathematics
Radio-Frequency Identification (RFID) shows great potential for earth-sciences applications, notably for landslide surface monitoring at a high spatio-temporal resolution with long-term robustness to meteorological events (rain, fog, snow). The ability to localize RFID tags using Unmanned Aerial Vehicles (UAV) in a Synthetic Aperture Radar (SAR) approach, would offer new possibilites for [...]
DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region
Published: 2024-10-20
Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Geomorphology, Physical Sciences and Mathematics
Retrogressive Thaw Slumps (RTS) and Active Layer Detachment Slides (ALD) are widespread thermal mass-wasting hillslope failures triggered by thawing permafrost. Despite increasing rates of these failures, knowledge about their pan-arctic spatial and temporal distribution remains limited. We present the Database of AI-detected Arctic RTS and ALD footprints (DARTS), the largest hillslope [...]
Interseismic deformation fingerprints on the hyperarid coastal landscape in North Chilean subduction
Published: 2024-10-10
Subjects: Earth Sciences, Geology, Geomorphology, Geophysics and Seismology, Tectonics and Structure
Along-strike seismotectonic behavior of subduction megathrusts feeds back into the forearc deformation as elastic and permanent deformation. However, whether and how short-term elastic deformation reflects long-term permanent deformation in the forearc and shapes the coastal region remains unclear. To evaluate the forearc deformation, we analyze the interseismic surface deformation obtained from [...]
Landscape evolution of the Black Forest: From the Variscan orogeny to the modern era
Published: 2024-09-28
Subjects: Geomorphology, Glaciology, Soil Science
With a maximum elevation of 1493 m above sea-level, the Black Forest (Schwarzwald in German) is the second highest mountain range in Germany. It is subdivided in three main natural regions, the northern, central, and southern Black Forest. The Variscan basement of the Black Forest consists of plutonic and metamorphic rocks. Sedimentary rocks formed during the Mesozoic under marine and terrestrial [...]
High-resolution geophysical monitoring of moisture accumulation preceding slope movement – a path to improved early warning
Published: 2024-09-25
Subjects: Environmental Monitoring, Geomorphology, Geophysics and Seismology, Hydrology
Slope failures are an ongoing global threat leading to significant numbers of fatalities and infrastructure damage. Landslide impact on communities can be reduced using efficient early warning systems to plan mitigation measures and protect elements at risk. This manuscript presents an innovative geophysical approach to monitoring landslide dynamics, which combines Electrical Resistivity [...]
Topographic analysis for mapping dunes and assessing dune field resilience using multitemporal LiDAR at White Sands, New Mexico
Published: 2024-09-25
Subjects: Geomorphology
Sand dune morphology is indicative of complex system interactions at a wide range of spatial and temporal scales that govern dune topographic structure. We created an object-oriented topographic framework based on slope attitude, curvature, and contextual analysis to map and characterize sand dune morphology at White Sands National Park, New Mexico, USA that limits empiricism and reliance on a [...]
Al Hawi, a 4-km-wide impact structure in northern Saudi Arabia

The northern region of Saudi Arabia hosts several impact craters and structures. This paper describes the discovery of a 4-km-wide complex impact structure located in the paleozoic sedimentary rocks of northern Saudi Arabia 210 kilometers north east of the city of Tabuk. The impact structure is composed of a central peak displaying intense folding and shock metamorphism surrounded by an inner [...]
Uncertainty aware sample mass determination of coarse-grained soils for particle size analyses

Determining particle size distributions (PSD) of soils is a basic first step in manygeotechnical analyses and guidance is given in different national standards. Forambiguous reasons, the recommended minimum sample mass (m_min) for the PSD-analyses of soils with a main component of gravel or greater is based on equationsincluding the soil's maximum grain diameter (D_max). We claim that the [...]
Novel landforms: integrating people as key drivers of process and form in geomorphology
Published: 2024-08-14
Subjects: Earth Sciences, Environmental Sciences, Geomorphology
People alter the earth’s surface in diverse and prolific ways, from enhancing physical and chemical erosion to controlling water transport across drainage networks. These modifications are often faster, more extensive, and wholly novel when compared to natural landscape evolutionary processes. Existing literature largely portrays people as independent of a landscape’s geologic and climatic [...]
Reconstructing past sea-level changes from storm-built beach ridges
Published: 2024-08-12
Subjects: Earth Sciences, Geology, Geomorphology, Sedimentology
Storm-built beach ridges, built by waves on sedimentary coasts, can be used as geomorphological indicators of past sea level. However, quantifying the relationship between the geomorphological elements of the ridge and the paleo sea level at the time of deposition is difficult, as a beach ridge is primarily correlated to wave energy and only secondarily to the position of sea level. In this work, [...]
Using Hydrogeomorphic Features to Quantify Structural and Functional Hydrologic Connectivity in a Coastal Plain Headwater Stream
Published: 2024-08-02
Subjects: Geomorphology, Hydrology
Headwater streams comprise most of the global river length, and hydrologic processes occurring in headwaters affect the chemical, physical, and biological functions of downstream aquatic ecosystems. However, we do not have a clear understanding of the spatial scales that drive hydrologic processes across headwater systems, particularly in Coastal Plain landscapes. We address this gap by [...]
