A geomorphological approach for enhancing environmental management and conservation of landforms as protected nature objects in the Upper Daugava spi…
2015
<p class="R-AbstractKeywords"><span lang="EN-GB">This paper describes the application of geomorphological approach for environmental management and conservation of landforms. Specifically, we discuss the contribution of geomorphological field survey and adapted matrix methodology (in combination with understanding of geology) to identification, study and evaluation of those abiotic nature elements which represent geological and geomorphological heritage. We describe a case study carried out in that part of the protected landscape area “Augšdaugava” which encompasses the Upper Daugava spillway valley. The study programme reported in this paper was realized to perform inventory of…
Preservation of modern and mis 5.5 erosional landforms and biological structures as sea level markers: A matter of luck?
2021
The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as tidal notches or shore platforms—are often used to define the tectonic stability of the Mediterranean coasts. We present the results of swim surveys in nine rocky coastal sectors in the central Mediterranean Sea using the Geoswim approach. The entire route was covered in 22 days for a total distance of 158.5 km. All surveyed sites are considered to…
Physiography of the Sicilian region (1:250,000 scale)
2015
Physiographic maps summarize and group the landforms of a territory into homogeneous areas in terms of kind and intensity of the main geomorphological process. These maps are often produced at semi-detailed scales, while examples at the regional scale are much less common. However, because the region is the main administrative level in Europe, physiographic maps can be very useful for land planning in many fields, such as ecological studies, risk maps, and soil mapping. This work presents a methodological example of a regional physiographic map, compiled at a 1:250,000 scale, representing the whole Sicilian region, the largest of the Mediterranean islands. The physiographic units were class…

Applicazione dell’analisi tridimensionale negli studi di Ecologia del paesaggio
2010
Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools t…

Geomorphology of the Anthropocene in Mediterranean urban areas
2019
Urban-geomorphology studies in historical cities provide a significant contribution towards the broad definition of the Anthropocene, perhaps even including its consideration as a new unit of geological time. Specific methodological approaches to recognize and map landforms in urban environments, where human-induced geomorphic processes have often overcome the natural ones, are proposed. This paper reports the results from, and comparison of, studies conducted in coastal historical cities facing the core of the Mediterranean Sea – that is, Genoa, Rome, Naples, Palermo (Italy) and Patras (Greece). Their settlements were facilitated by similar climatic and geographical contexts, with high gr…
