A GIS-based multiscale mapping framework to assess and visualize complex and polygenetic geomorphic systems – A novel ‘Geomorphic Entities’ approach
This paper presents a novel GIS-based methodological framework for multiscale digital mapping and database implementation in sediment dynamics assessments. It relies on the concept of ‘Geomorphic Entities’ (GEs), which are polygon objects representing complex, polygenetic geomorphic systems. GEs allow mapping ‘focal landforms’ as elementary mapping units, while the database stores hierarchical information on sediment sources/sinks classification,…
Natural landscapes preferred for the location of past watermills and their predisposition to preserve cultural landscape enclaves
This paper investigates the locations of past watermills in terms of their hydrological and geomorphological conditions. In our analysis, the natural landscape was treated as a resource of factors favouring or hindering the location of a specific mill and the possibility of their persistence as technological and economic conditions became increasingly unfavourable throughout history. An answer was provided to the question of which areas were envi…
Cavity detection using a pseudo-3D electric resistivity tomography at the Palaeolithic/Neolithic site of Scaloria Cave, Apulia, Italy
A pseudo-3D electrical resistivity tomography (ERT) survey has been carried out to detect cavities at the Neolithic/Palaeolithic site of Grotta Scaloria, close to Manfredonia, Apulia, Italy. Scaloria Cave has a rich history of archaeological research of more than 80 years and is one of the most important Neolithic complexes in the Mediterranean. Synthetic data modelling allowed to check the adequacy of the geophysical method and to develop a prop…
Policy implications of multiple concurrent soil erosion processes in European farmland
Evaluation of Gully Erosion Susceptibility Using a Maximum Entropy Model in the Upper Mkhomazi River Basin in South Africa
Soil erosion is one of the most challenging environmental issues in the world, causing unsustainable soil loss every year. In South Africa, several episodes of gully erosion have been documented and clearly linked to the presence of Quaternary colluvial deposits on the Drakensberg Mountain footslopes. The aim of this study was to identify and assess the triggering factors of gully erosion in the upper Mkhomazi River basin in KwaZulu-Natal, South …
Geomorphology of the upper Mkhomazi River basin, KwaZulu-Natal, South Africa, with emphasis on late Pleistocene colluvial deposits
We present a 1:50 000 scale geomorphological map of the upper Mkhomazi River basin, located in the foothills of the Drakensberg mountains in KwaZulu-Natal Province, South Africa. The sub-horizontal strata of the Permo-Triassic Beaufort Group forms plateau interfluves with a concave valley slope morphology. Locally, thick sequences of late Pleistocene colluvial deposits and associated buried paleosols (Masotcheni Formation) infill first-order trib…
Spatial analysis of hillfort locations in the Chełmno Land (Poland) using digital terrain analysis and stochastic data exploration
The location of hillforts is an extremely important issue in terms of understanding the functioning of the Middle Ages community. The multifaceted nature of hillfort localization factors requires an interdisciplinary approach. In this study we propose a methodology based on a detailed digital terrain analysis and the application of a predictive modelling procedure. The delineated terrain indices and present day landuse information allow for a cha…

The twofold aim of the workshop was: (1) to provide an overview of approaches and methods that are presently used to incorporate paleoenvironmental information in human–environment interaction modeling applications…
Channel planform changes along the Scrivia River floodplain reach in northwest Italy from 1878 to 2016
A detailed, quantitative, multitemporal analysis of historical maps, aerial photos, and satellite images was performed to investigate the channel planform changes that occurred along the Scrivia River floodplain from 1878 to 2016. Various channel planform features, including channel length, area, width, braiding, sinuosity, lateral migration, activity, and stability, were computed through an innovative geographic information system–based procedur…
Litho-structure of the Oltrepo Pavese, Northern Apennines (Italy)
In this article we present a detailed litho-structural map of the Oltrepo Pavese, a sector of the Northern Apennines, Southern Lombardy, Italy. Lithology and geological structures are an important basis for different disciplines of Earth Sciences. In particular, for the assessment of earth surface processes such as soil erosion, mass movements, flooding, etc. The Oltrepo Pavese is characterised by a complex geology and related tectonic settings. …
Assessment of soil erosion risk in a typical Mediterranean environment using a high resolution Rusle approach (Portofino promontory, NW-Italy)
Particularly the Liguria region in Northern Italy is highly affected by soil erosion processes. This study was conducted in the Portofino promontory in eastern Liguria, to predict potential annual soil loss using the Revised Universal Soil Loss Equation (RUSLE). Moreover, we evaluate the relative accuracy of the predictions at detailed scale, using high resolution spatial information for model calibration. The RUSLE factors were calculated for th…
Geomorphological processes, forms and features in the surroundings of the Melka Kunture Palaeolithic site, Ethiopia
The landscape of the surroundings of the Melka Kunture prehistoric site, Upper Awash Basin, Ethiopia, were studied intensively in the last decades. Nonetheless, the area was mainly characterized under a stratigraphic/geological and archaeological point of view. However, a detailed geomorphological map is still lacking. Hence, in this study, we identify, map and visualize geomorphological forms and processes. The morphology of the forms, as well a…

Explorative Spatial Analysis of Neandertal Sites using Terrain Analysis and Stochastic Environmental Modelling
In this paper we present a unique spatial dataset of Neandertal sites in Europe. Information on topographic locations with human fossils was collected in the course of our own work and from a comprehensive literature review. The fossils are classified into Pre-Neandertals, Early Neandertals and Classic Neandertals. Based on this dataset, we explored the environmentally constrained site-selection criteria of Neandertals. The site locations are des…

Relación entre el cambio de uso del suelo en la cuenca del Aconcagua y su litoral arenoso correlativo
En la cuenca del Aconcagua los procesos de modernizacin e intensificacin del uso de suelo se han traducido tanto en una reconversin agrcola como en el aumento de la superficie explotada. Tal proceso ha sido muy intenso en la medida que se han incorporado nuevos terrenos, sobrepasando los lmites del valle y orientndose hacia tierras en pendiente. Ello ha incidido en los procesos de transferencia de masa desde la cuenca hacia la desembocadura. Para…

Future long-term changes in global water resources driven by socio-economic and climatic changes
A global water model is used to analyse the impacts of climate change and socio-economic driving forces (derived from the A2 and B2 scenarios of IPCC) on future global water stress. This work extends previous global water research by analysing not only the impact of climate change and population, but also the effects of income, electricity production, water-use efficiency and other driving forces, on water stress. Depending on the scenario and cl…
