Summary: Distinct stages of deformation and fluid flow-related diagenetic alterations are recorded in Lower Miocene sandstone and conglomerate of the Pannonian Basin in Central Europe. Multiple generations of structural elements and host rocks were investigated using petrographical and geochemical methods, providing insights into the spatial and temporal evolution of deformation mechanisms and diagenetic processes. The integration of acquired data into a subsidence model reveals the effects of intense subsidence on basin-wide fluid-flow evolution.

Summary: Heterogeneity and anisotropy of lithological units affect hydraulic conductivity at various scales. This study presents a novel method to classify hydrostratigraphy by considering variations in sand content and depositional environment. The method was applied to fluvio-deltaic deposits in Hungary, using seismic volumes, master horizons, and well logs. The results allowed for the identification of different sand bodies and the evaluation of sand distribution patterns. The workflow, adapted from the oil-and-gas industry, successfully distinguished units of varying sand content and hydraulic conductivity, providing a robust geological model for fluid flow analysis.

Summary: This paper analyzes extreme meteorological droughts in the Pannonian Basin in central and southeastern Europe using historical data from 1981-2010. The results show that the central and northern part of Hungary and the entire territory of Vojvodina Province in Serbia experienced the longest droughts, lasting on average 55-60 days. The theoretically longest 100-year droughts could be expected in the northern part of Hungary, the eastern part of Romania, and Serbia, with a duration of up to 70 days.

Summary: This study investigates the cryogenic structuring in the watershed landscapes of the Central Russian Plain. Through the use of aerial and satellite imagery and geological investigation techniques, the researchers were able to identify and correlate three generations of wedge casts and a specific bulbous type of cast. These cryogenic features provide valuable information for paleoenvironmental reconstructions. However, the regular polygonal patterns caused by these features are almost erased in the modern topography.

Summary: Based on the analysis of cores, wire logging, and seismic data, this study reveals the characteristics of depositional systems and tectonic control during the early and late rift stages in the eastern part of the Drava Basin. The early stage is dominated by continental and lacustrine deposition, while the late stage is characterized by marine deposition and volcanic activity. Sediment transport pathways are mainly formed by ramps, basin slopes, and fault scarp slopes. This study provides an example of syn-rift tectonic control and discusses the influence of detachment geometry on basin fill.

Summary: The Pannonian Basin complex has a cumulative production of approximately 13 billion BOE. Estimates suggest that there are over 5 billion BOE of combined conventional and unconventional hydrocarbon potential remaining in this mature basin. The presence of multiple source rocks, stacked reservoirs, thick basin fill, established infrastructure, subsurface data, and access to markets make the Pannonian Basin similar to other super basins.

Summary: This study shows that morphometric indices derived from high-resolution DEMs can be used to estimate flash flood susceptibility in mountainous areas. The selected indices, including drainage density, drainage texture, and relief ratio, have a direct impact on flash flood generation, while other indices such as area and form factor are inversely related to the intensity of flash floods. The study also highlights the need for further GIS analyses to understand the anthropogenic controls on flash flood hazard.

Summary: Abrupt and large-scale climate changes during the last glaciation have been well-represented in Greenland ice core records. However, the feedbacks between atmospheric dust and these climate change events, known as Dansgaard-Oeschger events, are poorly understood. To shed light on this, a multi-technique study of Greenland dust provenance was conducted. The results challenge the existing dominant model and suggest that Greenland dust may originate from the Taklimakan Desert in western China, European glacial sources, or a mix of European and North African dust. These findings demonstrate the complexity and uncertainty of dust climate feedbacks during abrupt events.

Summary: Artificial levees are crucial for flood-risk mitigation, especially in Hungary where more than one-third of the country is threatened by floods and protected by a 4200-km-long levee system. However, these levees built in the 19th century may have undergone slow but steady deformation due to various processes. Since there is limited documentation on relevant construction works, the structure and composition of artificial levees are not well known.

Summary: This study reconstructed the formation of fluvial terraces along the middle section of the Mures/Maros River in Romania, and found that their formation was mainly controlled by climatic factors, especially the incision during climatic transitions and valley aggradation during glacial periods. The study also highlighted the influence of tectonic setting on terrace development. Therefore, the results not only explain the formation process of fluvial terraces in the study area, but also provide insights for terrace formation at other rivers in the region.
