The properties of sediment grain shape provide valuable information about the transport mechanisms in different sedimentary and geomorphological environments. With emergence new, high-resolution analytical techniques, it has become possible to quickly examine a large number individual mineral grains. In this study, we used automated image analysis (Malvern Morphologi G3SE-ID) investigate particles four types from depositional environments (sand sheet (1), floodplain (2) fluvial channel...

ABSTRACT The paper investigates environmental conditions prevailing at the southern margin of European periglacial domain in NW Hungary (Kemeneshát area) during Late Pleistocene. Samples sediments infilling sand wedges and their host were analyzed by examining grain‐size distributions, as well morphology microtextural characteristics (250–500 μm) quartz grains. surface 460 grains with a scanning electron microscope to infer sedimentary processes that affected sediments. number frost‐induced...

Wedge structures and involutions suggest that L ate P leistocene frozen ground, either permafrost or deep seasonal frost, extended at least as far south latitude 47° N in central E urope (the annonian B asin). Optically stimulated luminescence dating of the sand infill from a number wedges indicates emplacement occurred during (22.2–15.7 ka). This suggests this time mean annual air temperature was depressed by ∼15° C relative to present. Either continuous discontinuous probably present north...

Abstract Relict sand‐wedge polygons are described from palaeosol and gravel deposits in the Mogyoród area, Hungary. Based on previously reported periglacial features, local glacial history optically stimulated luminescence (OSL) dates, these features suggest that Pannonian Basin was underlain by permafrost during Late Pleniglacial (22 000–18 000 years ago) may have been continuous.

The availability of global coverage digital surface models (like ASTER GDEM or SRTM) and the variation fused based on these EU-DEM) still has a great impact scientific researches, as they provides fairly good base dataset with low production time expenses. However, validation reports initial DSMs convinced different characteristics errors, thus it is essential to examine height datasets prior application. A verifying process for EU-DEM more important, because been published without formal...

Abstract The Pannonian Basin was located in the southernmost, disputed limit of permafrost during Last Glacial Maximum (LGM). In western part basin, over an area 1,200 km 2 , more than 150 sites with polygonal patterned ground were surveyed, and 72 sediment samples from forms identified as relict sand wedges collected. Ten optically stimulated luminescence ages obtained infills, while morphometric analyses also carried out on satellite images. Our study revealed that networks developed...

Abstract This article presents results from the survey conducted on Dunaszekcső loess bluff after last major rotational sliding event in 2008. The study area is a region of 25×30 m located close to recent scarp. relative elevation change surface was surveyed 2.5×5 grid network relation marked base point. using simple equipment such as analogue theodolite and leveller with regular time interval during year control measurements were taken six months. It assumed that nearest cm are sufficient...

There are several common tools and practices to record surface displacement, monitor characterise landslide development. However, is it possible use only total station monitoring network gain useful information for mass movement detection characterisation? In our study, we focus on the field of Castle Hill area (south-eastern Transdanubia, Hungary) provide a methodology displacement processes. A 5 × m resolution grid was set up cover active stable parts hill surveyed 27 times between 2011...

Increasingly severe hydrological extremes are predicted for the Pannonian Basin as one of consequences climate change. The challenges extreme droughts require adaptation agriculture especially during intense growth phase crops. For dryland farming, selections optimal land use type and sustainable agricultural management potential tools facing posed by increased aridity. To this end, it is indispensable to understand soil moisture (SM) dynamics under different types over drought-affected...

Abstract Morphometric indices from high-resolution DEMs can contribute to the estimation of flash flood susceptibility in mountainous areas. We have screened 25 morphometric commonly used literature, and based on a correlation matrix, selected those which showed strongest relationship with generation: area ( A ), drainage texture (Rt), density (Dd), elongation ratio (Re), form factor (Ff), lemniscate method k Gravelius coefficient (GC), forested (Fa) relief (Rr). Among them Dd, Rt Rr had...

Over the past decades, in mountainous, hilly and/or urban areas of Hungary several high-intensity storms were followed by severe flash flooding and other hydrologic consequences. The overall aim this paper was to upgrade national flood susceptibility map first published Czigány et al. (2011). One elementary watershed level (FFSIws) three settlement maps (FFSIs) constructed using 13 environmental factors that influence generation. FFSI verified 2,677 documented events. In total, 5,458...

Increasingly severe weather extremes are predicted as one of the consequences climate change. According to climatic models, extremities induce higher risks for both flood and drought in Carpathian Basin. Throughout 19th 20th centuries, control relied on cost-intensive engineering structures, but recently ecological solutions have come fore. Flood hazard major rivers could be mitigated if multiple cumulative water retention opportunities exploited upper sections tributary catchments....

Terroir refers to the geographical origin of wines. The landscape factors (topography, parent rock, soil, microbial life, climate, natural vegetation) are coupled with cultural (cultivation history and technology, cultivars rootstock) all together define a terroir. physical can be well visualized by slope profile developed into pedosequence showing regular configuration relevant for wine district. In present study generalized topographic (or catena) GIS spatial model Villány Hills,...

Comprehensive field survey of the physiographic context and channel morphology is a key to distinguish characteristic hydrogeomorphic reaches watercourse. In this analysis data were collected during seasonal campaigns following protocol developed in Polish Carpathian Mountains. Complementary information was conducted from cartographic materials digital elevation model map diverse sections semi-natural Váralja Stream Eastern Mecsek Geological, geomorphological anthropogenic effects had be...

Adaptation to climate change demands the optimal and sustainable water management in agriculture, with an inevitable focus on soil moisture conditions. In current study we developed ArcGIS 10.4. platform-based application (software) model spatial temporal changes a soy field.

Small catchments in mountainous regions affect downstream rivers as a primary source of sediment supply and also generate flash swasfloods, especially during extreme events. These floods have significantly shaped the small streams Mecsek Hills some rural areas over past two decades. However, there has been no previous study examining hydromorphology headwater low mountain environments Hungary. The present was meant to investigate fundamental hydrogeomorphological properties first-order...

Many nature reserves and protected areas are found in the Southern Transdanubian Region (SW Hungary) they partly belong to operational area of Duna-Dráva National Park (DDNP). In current paper we review potential geohazards that may affect area. Our results indicate predominant include large riverine floods on alluvial plains, while a high-degree vulnerability is generated owing high relief. High relief trigger intense runoff following rainfall events downpours, where consequences, such as...
