Abstract:

AbstractThe objective of the present study is to evaluate the relation between the spatial and temporal dynamics of Land Use and Land Cover (LULC) and the hydro-geomorphological processes and their impacts. The study area is the city of Leiria, in central Portugal, within the period 1958–2018 based on the historical record of floods and landslides disasters. The LULC analysis shows an accentuated increase in the artificial areas and a continuous decrease in the agricultural areas. With regard to hydro-geomorphologic disaster occurrences, a total of 124 occurrences were identified, having caused a set of impacts. The obtained results allow one to characterize the artificialization process, its intensity and territorial dispersion, as a consequence of urban sprawl and peri-urbanization, along with its consequences in exposure to hydro-geomorphological processes. The analysis concludes that changing the risk drivers resulted in an increase in frequency and spatial dispersion of hydro-geomorphologic disasters over the analysed period.

Abstract:

Main issues related to the geomorphological mapping of quarries are discussed. The stages of creating these maps are characterized. The first stage is the analysis of raw materials and prefield mapping. The relief in contours with a relatively small value of horizontal crossing (2 m) is depicted in surveying and topographic maps and plans of mines (scale 1:500–1:5000). According to topographic maps and plans of mining the boundaries of main elements of relief can be quite easy to distinguish, and sometimes their genesis can be set. Space photos help to identify not only the major but also the minor (small) elements and forms of relief and micro-relief surfaces (flat, hilly etc.). As a result of preparatory (prefield) the geomorphological map-hypothesis (preliminary geomorphological map) is worked out, the main morphological elements of relief are highlighted there to the most possible extent. The second most important, phase is field mapping. The main task is to identify the complete and final elements and landforms. Four major components of the quarry relief, which are represented on geomorphic maps (its morphology, genesis, age and dynamics) are analysed. The relief morphology is the most essential part of the content of geomorphologic maps of quarries. The morphological criteria define the boundaries of cells and landforms, and confirm or deny the previously allocated limits, specify them (including changes in the relief that have occurred in recent years) and circumstance them. The genesis of quarries relief, in general, is purely anthropogenic. Depending on the relief forming factor (anthropogenic denudation or accumulation) the main genetic categories of relief are distinguished respectively: excavated (or denudational) and accumulative. The age of the relief is determined by the fund and literary sources, topographic and surveying maps, remote materials. Additional criteria that can be found in field studies can also be used, such as: 1) herbage (amount of turf); 2) forestry (approximate age of trees); 3) the severity of morphological forms. Contemporary geomorphological processes in quarries are the natural and anthropogenic processes that occur in man-made terrain, but act as natural. From the experience of personal research, the most common processes include landfall-landslides processes, linear erosion, sheet erosion, upheaval, suffusion. Some other characteristics that are represented on geomorphological maps include geological structure, vegetation, hydrological features. The main geological characteristic is the lithology of deposits, first and foremost the lithology of career ledges (loam, sand, marl, limestone, sandstone etc.). Vegetation on geomorphic maps of quarries is of secondary importance. Its presence indicates the relative maturity of the human terrain, insignificant activity of modern exogenous processes. Hydrological features of quarries usually consist in the amount of water on separate areas (bottoms of quarries) and waterlogging. The last stage is drawing the legend and mapping of the geomorphological map. Legend to the geomorphological map consists of the following components: 1) the types of human terrain, which are divided into key elements (rarely forms) of relief; 2) small (minor) elements and landforms; 3) the contemporary geomorphological processes (contemporary morphodynamics); 4) other markings. The most essential in the legend is the first part that actually describes the main elements and landforms of quarry relief grouped according to genetics and further divided by age and morphology, topography, geological and hydrological characteristics, vegetation. There are no specific standards as to geomorphological maps mapping. There are black and white and colour versions of the maps. Key words: quarry, anthropogenic relief, geomorphological mapping, geomorphological maps stages of construction, contemporary morhpodynamics

Abstract:

AbstractThe Mema is a semi-arid region in central Mali with a rich archaeological heritage indicating the former existence of large urban settlements. The archaeological data suggest millennia of occupation history of the Méma preceding relatively sudden abandonment by the 14th or 15th century AD. Population numbers have remained low since then and today’s human presence in the area is sparse and largely mobile. Geomorphologically, the Méma can be characterized as a graben hosting various generations of aeolian landforms and (presently mostly dry) interdunal channels and lakes, linked to the neighbouring Inland Niger Delta floodplain. Given this setting, and the variability of the Sahelian climate, climatic contributions to the region’s sudden abandonment are likely. A geomorphological survey of the region, and interpretation of the observed geomorphological record in terms of climatic history, aimed at providing a basis for understanding the intensive occupation and subsequent abandonment of the Méma. The results of this study underscore dramatic Holocene climatic variability, leading to the region’s present geomorphological diversity, but also suggest that neotectonic movements constitute an important additional cause of regional desiccation. Both may have encouraged prehistoric people to abandon the Méma after a long period of occupation.

Abstract:

Abstract. Riparian zone delineation is a central issue for managing rivers and adjacent areas; however, criteria used to delineate them are still under debate. The area inundated by a 50-yr flood has been indicated as an optimal hydrological descriptor for riparian areas. This detailed hydrological information is usually only available for populated areas at risk of flooding. In this work we created several floodplain surfaces by means of two different GIS-based geomorphological approaches using digital elevation models (DEMs), in an attempt to find hydrologically meaningful potential riparian zones for river networks at the river basin scale. Objective quantification of the performance of the two geomorphologic models is provided by analysing coinciding and exceeding areas with respect to the 50-yr flood surface in different river geomorphological types.

Abstract:

The paper has two main aims. Firstly, to postulate a physical geodatabase model of a geomorphological information system based on the already existing logical geodatabase model. Secondly, to define processes of geomorphological analysis based on the physical geodatabase model. The structure of the physical model follows the logical model and is divided into three parts: adopted layers (hydrology, geology, topography and others), basic layers (elementary forms, digital elevation model and derivatives, documentation materials, genetic groups of landforms, morphodynamic phenomena, basin based features and geomorphic network) and special layers (morphostructural analysis, comprehensive geomorphological analysis and so on). The geodatabase modelling methodology was used for developing the physical geodatabase model. The geomorphological analysis is based mainly on the layer of elementary forms (defined according to their morphology and morphometry) and the derived layer of morphogenetical forms (determined by genesis of landforms). The traditional methods of geomorphological mapping and also more recent concepts of geomorphological analysis were used. The concept is presented in the context of research in the surroundings of Prášilské jezero (lake) in the Šumava (Mts.). ESRI products were used to carry out the project.

Abstract:

<p>Geomorphology depicts the qualitative and quantitative characteristics of both terrain and landscape features combined with the processes responsible for its evolution. Soil erosion by water involves processes, which removes soil particles and organic matter from the upper sheet of the soil surface, and then transports the eroded material to distant location under the action of water. Very few studies have been conducted on the nature and dynamics of soil erosion in the different geomorphologic features. In the present investigation, an attempt has been made to assess the control of geomorphologic features on the soil loss. Universal Soil Loss Equation (USLE) was used to determine soil loss from the various geomorphological landforms. Principal component analysis (PCA) was implemented on the USLE parameters to determine the degree of association between the individual principal components and the USLE-derived soil loss. Results obtained from the investigation signify the influence of the various landforms on soil erosion. PC5 is found to be significantly correlated with the USLE-derived soil loss. The results ascertained significant association between the soil loss and geomorphological landforms, and therefore, suitable strategies can be implemented to alleviate soil loss in the individual landforms.</p>

Abstract:

The main focus of the article is the significance of the geomorphological method for the reconstruction of paleogeographic events that took place in the Late Pleistocene and Holocene. The specific data obtained as a result of applying this method are given. A reasonable curve of the Caspian Sea level fluctuations in the Holocene was compiled. A risk zone has been defined, within which the level of the Caspian Sea will fluctuate in the future, under modern physics-geographical conditions, which is fundamental importance when planning any economic measures in the coastal zone. Predictions were made and later justified of the Caspian Sea level fluctuations in the 20thearly 21st centuries. The climatic nature of the Caspian transgressions was confirmed. Obtained were new data on the evolution of the shores of the Caspian Sea under rising level conditions, which can be used when forecasting the development of the shores of other seas in the conditions of the present-day rise of the World Ocean level.

Abstract:

Landforms on the earth surface are so expensive to map or monitor. Remote Sensing observations from space platforms provide a synoptic view of terrain on images. Satellite multispectral data have an advantage in that the image data in various bands can be subjected to digital enhancement techniques for highlighting contrasts in objects for improving image interpretability. Geomorphological mapping involves the partitioning of the terrain into conceptual spatial entities based upon criteria. This paper illustrates how geomorphometry and mapping approaches can be used to produce geomorphological information related to the land surface, landforms and geomorphic systems. Remote Sensing application at Razzaza–Habbaria area southwest of Razzaza Lake shows the different geomorphologic units and the land use maps that were delineated from Landsat ETM+ Image. Digital Image unsupervised classification was adopted to delineate the different classes by applying ERDAS 8.4 software. According to this classification five classes were selected and delineated in different colors.

Abstract:

The article presents a methodological approach to assessing the geomorphological safety of sea coasts based on the close interdependence between geomorphological conditions and active coastal recreational activities. One of the key stages of the proposed assessment is recreational-geomorphological zoning, which results in separation of regions, districts and local areas in relation to relief homogeneity and recreational situation. The suggested approach is based on the quantitative indicators of the environment — conditions of relief formation and the geomorphological properties of the territory. Group of criteria for the situation of relief formation includes lithological, hydrometeorological, human and social factors. Among the group of geomorphological criteria are: morphometric characteristics of the coast, the dynamics of the coast and the activity of slope processes. Resultant geomorphological safety was classified into three classes: the most suitable areas for recreation; territories subject to further refinement; and inconvenience territories that cannot be used at all. The results of the geomorphological safety assessment are designed to increase the effectiveness of recreational environmental planning. The suggested principles of geomorphological assessment can be used not only for the Baltic region, but almost for any coastal region, which may require some correction of criteria.

Abstract:

Albania is characterized by a typically alpine accidented mountain relief. About half of the country (48.1 %) belongs to 200-1000 m altitude belt, and 28.5 % belongs to the levels higher than 1000 m. The average altitude is 708 m., i. e., twice more than high average of Europe. As a result the horizontal Smosh coefficient is more than 3 km/km2. There are formed some genetical types of relief, and namely, structural-erosional, karstic, river-erosional, erosional-denudated, glacial, seacoast. Geological-tectonical evolution, varied kinds of rocks, climate changes and countinuos action of the atmospheric agents have influenced the formation of different kinds of morphological forms of the relief. In such a manner are formed a number of geomorphological sites of natural aesthetic and scientific importance or with climate-curative features. The very dense river net with common tendence from east to west caused formation of many erosional sites. The large surface of carbonate rocks (6600 km2) and evaporite ones favoured formation of karstic plateaus, fields, holes, and caves. Glacial events have their traces as well, especially on the high mountains of Albania. They form lakes, circus, morains, lagoons, etc. often of geomonumental values. Geomorphological sites in Albania are widespread mainly in the Northern Mountain Region (Albanian Alps), central and southern mountain units and less in the hilly-field near the Adriatic sea coast. They are of local, district’s, national and some of Balkan or European importance.

Abstract:

Abstract. This work deals with the elaboration of flood hazard maps. These maps reflect the areas prone to floods based on the effects of Hurricane Mitch in the Municipality of Jucuarán of El Salvador. Stream channels located in the coastal range in the SE of El Salvador flow into the Pacific Ocean and generate alluvial fans. Communities often inhabit these fans can be affected by floods. The geomorphology of these stream basins is associated with small areas, steep slopes, well developed regolite and extensive deforestation. These features play a key role in the generation of flash-floods. This zone lacks comprehensive rainfall data and gauging stations. The most detailed topographic maps are on a scale of 1:25 000. Given that the scale was not sufficiently detailed, we used aerial photographs enlarged to the scale of 1:8000. The effects of Hurricane Mitch mapped on these photographs were regarded as the reference event. Flood maps have a dual purpose (1) community emergency plans, (2) regional land use planning carried out by local authorities. The geomorphological method is based on mapping the geomorphological evidence (alluvial fans, preferential stream channels, erosion and sedimentation, man-made terraces). Following the interpretation of the photographs this information was validated on the field and complemented by eyewitness reports such as the height of water and flow typology. In addition, community workshops were organized to obtain information about the evolution and the impact of the phenomena. The superimposition of this information enables us to obtain a comprehensive geomorphological map. Another aim of the study was the calculation of the peak discharge using the Manning and the paleohydraulic methods and estimates based on geomorphologic criterion. The results were compared with those obtained using the rational method. Significant differences in the order of magnitude of the calculated discharges were noted. The rational method underestimated the results owing to short and discontinuous periods of rainfall data with the result that probabilistic equations cannot be applied. The Manning method yields a wide range of results because of its dependence on the roughness coefficient. The paleohydraulic method yielded higher values than the rational and Manning methods. However, it should be pointed out that it is possible that bigger boulders could have been moved had they existed. These discharge values are lower than those obtained by the geomorphological estimates, i.e. much closer to reality. The flood hazard maps were derived from the comprehensive geomorphological map. Three categories of hazard were established (very high, high and moderate) using flood energy, water height and velocity flow deduced from geomorphological and eyewitness reports.

Abstract. The aim of the paper is to apply an object-based geomorphometric procedure to define the runoff contribution areas and support a hydro-geomorphological analysis of a 3 km2 Mediterranean research catchment (southern Italy). Daily and sub-hourly discharge and electrical conductivity data were collected and recorded during a 3-year monitoring activity. Hydro-chemograph analyses carried out on these data revealed a strong seasonal hydrological response in the catchment that differed from the stormflow events that occur in the wet periods and in dry periods. This analysis enabled us to define the hydro-chemograph signatures related to increasing flood magnitude, which progressively involves various runoff components (baseflow, subsurface flow and surficial flow) and an increasing contributing area to discharge. Field surveys and water table/discharge measurements carried out during a selected storm event enabled us to identify and map specific runoff source areas with homogeneous geomorphological units previously defined as hydro-geomorphotypes (spring points, diffuse seepage along the main channel, seepage along the riparian corridors, diffuse outflow from hillslope taluses and concentrate sapping from colluvial hollows). Following the procedures previously proposed and used by authors for object-based geomorphological mapping, a hydro-geomorphologically oriented segmentation and classification was performed with the eCognition (Trimble, Inc.) package. The best agreement with the expert-based geomorphological mapping was obtained with weighted plan curvature at different-sized windows. By combining the hydro-chemical analysis and object-based hydro-geomorphotype map, the variability of the contribution areas was graphically modeled for the selected event, which occurred during the wet season, by using the log values of flow accumulation that better fit the contribution areas. The results allow us to identify the runoff component on hydro-chemographs for each time step and calculate a specific discharge contribution from each hydro-geomorphotype. This kind of approach could be useful when applied to similar, rainfall-dominated, forested and no-karst catchments in the Mediterranean eco-region.

Abstract:

The article reviews publications devoted to geological and geomorphological monuments of Ukraine highlights specific features of their formation in different regions and reveals their importance for the development of nature-cognitive tourism as a basis for the formation of the tourism industry. The methodological unity of the concepts "geological monuments" and "geomorphological monuments", which characterize the original course of natural processes and their results and therefore have great scientific and cognitive value are considered. Emphasis is placed on the important participation of geomorphological processes in the formation of natural monuments, which show different geological monuments on the earth's surface and reflect not only the features of geological factors but also the diversity of relief processes, their dynamics, which determines the status of most monuments as "geological and geomorphological". Important for establishing the protection status of geological and geomorphological monuments are the developed criteria for assessing the aesthetics of the relief of Ukraine, its uniqueness, the presence of features "architecture-composition", combination with other elements of the landscape, stability or mobility, imagery – photogenicity, visual effect, emotional perception, attractiveness, etc. It is noted that the category of natural phenomena "geological and geomorphological monuments" is characterized by significant conservatism compared to other components of the natural environment. Such monuments are carriers of paleogeographic and ethnocultural content, which, in addition to scientific significance, gives them the status of interesting tourist attractions. This creates an opportunity for the development of nature-cognitive tourism, which can be both independent and successfully complements all other known types of tourism. Geological and geomorphological monuments influence the nature of recreational activities. The specificity and sequence of recreational functions of the relief of Ukraine according to the special properties of endogenous, exogenous, and anthropogenic genetic varieties of recreational geological and geomorphological monuments have been established. Key words: geotourism; nature-cognitive tourism; geological-geomorphological monuments; geoheritage of Ukraine.

Abstract:

Despite of the geomorphological diversity of Central America and Costa Rica, there are few detailed geomorphological studies in the region. A 1:25,000 geomorphological analyses of the Upper General River Basin (UGRB) located in the southeast in Costa Rica is presented, based on the interpretation of aerial photographs and field geomorphological mapping. First, a morphometric analysis was performed to calculate and analyze seven variables that were merged in order to produce the flood and landslides susceptibility maps. Second, a total of 43 types of landforms divided genetically into endogenic (tectonic), and exogenic (fluvial, gravitational, and glacial) features are mapped for an area of 1560 km2. Finally, a geomorphological hazard map with the zonation of the different susceptibility levels of landslides and floods were performed. This cartography is important in terms of geomorphological evolution, disaster risk reduction as well as for land use planning for approximately 40,000 inhabitants. The presented methodology can also be applied in other developing countries for different purposes such as landscape evolution, morphogenetic detailed maps, disaster risk reduction, and land use planning.

Abstract:

Examples of relief studies by seven prominent Russian soil scientists, representatives of the Dokuchaev school, are presenterd. Geomorphological issues, ideas and concepts in the works of soil scientists of the XX century. showed their high professional interest in geomorphology. The beginning of the geomorphological research of Russian soil scientists was laid by the great Russian researcher V. V. Dokuchaev. Geomorphological views of V. V. Dokuchaev were ahead of the V. M. Davis' concept of the geographic cycle. Soil-geomorphological studies of S. S. Neustruev partially supplemented the concept of V. M. Davis. B. B. Polynov proved the necessity of attracting geomorphological methods and techniques when conducting soil studies, used geomorphological principles in the deduction of the three laws of the distribution of weathering crusts. I. P. Gerasimov created the theory of morphostructure and morphosculpture, introduced the idea of three macrocycles in the history of the formation of the Earth's landscapes. All the researchers cited in the article conducted detailed complex studies using geodesy methods. Scientists were able to identify a large array of new geomorphological data from the classification of microrelief to the adjustment of the main laws of geomorphology. The main feature of the scientific activity of Russian soil scientists-geomorphologists was the Dokuchaev school that gave rise to all them. It was from the Dokuchaev's principles and approaches that the mentioned scientists started and developed and passed to their students and followers. The well known Russian soil scientist and geomorphologist I. P. Gerasimov completed the century-long period of the geomorphological studies by soil scientists started by V. V. Dokuchaev.

Abstract:

The purpose of this work is to show the possibilities of regional geomorphological and geological-geophysical methods for studying the tectonic and geomorphological features of the structure of central-type ring structures on the territory of the Middle Urals (Tatarstan, Udmurtia, Bashkiria, Kirov Region) and adjacent regions of the Komi-Permyat Autonomous Region, allowing to study the oil and gas prospects of these territories. According to the results of geological and geophysical interpretation of the data of magnetic exploration, gravity exploration and heat flow, the deep structure of the root inhomogeneities of the Voy-Vozhsky ring geomorphological structure of the central type, one of the analyzed in the territory of the Middle Urals, is shown. It is assumed that the intersection points of tectonic faults of the Earth's crust (geomorphological liniments) located in the side zones of circular geomorphological structures of the central type on the territory of the Middle Urals and adjacent regions can be promising objects of geological and geophysical research in search of oil deposits. Gas fields can be confined to the central zones ("pipes" of mantle degassing) of circular geomorphological structures of the central type.

Abstract:

Understanding geomorphological characteristics must provide morphographic, morphometric,morphogenetic, and morphochronological information. This study aims to identify geomorphological characteristics in the Prambanan hills area compiled in the form of a geomorphological map. The research is based on maps, previous research reports, and field observations in the form of field checks on theelements studied. The geomorphological mapping system used is the ITC system. The main analysis in this research is spatial analysis in the form of overlapping spatial data. The relationship between landform units,lithology, and slopes is information that is analyzed descriptively. The results showed that on a map with a scale of 1: 30,000, 9 geomorphological units could be identified. The 9 geomorphological units are a combination of morphometry, genetics, and lithology. The combination consists of 2 landforms, namelytraditional and structural hills, and slopes; The lithology consists of 3 layers, namely the Lapili Formation of Semilir, Sand Formation of Kebo Butak, and Tuff Formation of Semilir. While the morphometry is in theform of slope units, namely 8-15%, 15-25%, 25-45%, and >45%. While the age based on lithology is Late Oligocene – Early Miocene in the Kebo Butak Formation and Early Miocene – Middle Miocene in theSemilir Formation.

Abstract:

Abstract The risk assessment of the dangerous geomorphological processes development in the Dauria steppes in conditions of pronounced cyclical fluctuations in climate and high dynamism of geomorphological systems is carried out on a five-point scale. The analysis of the spatial and temporal structure of fluvial and aeolian processes for the purposes of nature management is fulfilled. The role of extreme geomorphological events is shown, which are a serious limiting factor of conflict-free nature management in the Daurian region. The revealed catastrophic manifestations of fluvial and aeolian processes require careful planning of economic activities and serious environmental protection measures. The result of the assessment is the zoning of the Dauria territory according to the degree of geomorphological risk. The types of economic activities that do not violate the stability of the regime of geomorphological systems, and, on the other hand, are undesirable, increasing the risk of critical natural situations, are indicated.

Abstract:

During the formation of a frazil-generated ice cover, ice bridging can occur along sections of rivers that are geomorphologically suited (e.g. very sinuous, narrowing channel width, low gradient bed slope) to arrest the flow of ice pans. Bridging may occur at several locations along the river independently from one another with separate ice cover formations occurring simultaneously. Juxtaposition of incoming frazil ice and ice pans extending from the ice bridgings can cause backwater levels to rise upstream and cause flooding. The separate ice covers will eventually merge to completely cover the river sooner than if no additional bridging had occurred. This makes it difficult to predict the time required for a river to be completely ice covered and the locations and timing of related potential flood events. A geospatial model is introduced in this paper that applies a principal component analysis to cluster geomorphological features – such as sinuosity, channel width and channel slope – into typologies. Certain combinations of these typologies reveal predisposition of certain geomorphological features to ice bridging or non-bridging. The Dauphin River in Manitoba is used as a test case for the development of the model.

Abstract. Within the framework of geomorphosite assessment with reference to tourism potential, a new field of research has opened up focusing on sites used for outdoor activities, like free climbing. This line of research in particular focuses on the suitability of geological and geomorphological characteristics of a specific site for a particular sport. Concentrating on geomorphological hazard, rock quality, tourism capacity and site vulnerability, a method of assessment was designed and tested on a number of important Itahan climbing sites. Using the results of the Monteleone Rocca Dona (Sardinia, Italy), the article presents the proposed approach of assessment. Although the site in question is recognised for its «scientific», «aesthetic» and «cultural value», it has drawn attention for its attractiveness for rock climbers in particular. Thus, the aim of the assessment was to support management of the site by proposing options for utüisation that are sensitive to both the needs of the climbers and the environment in which the site is embedded. In particular, attention was given to potential geomorphologically-related risks for climbers, the impacts linked to human presence and the specific characteristics of the geomorphosite.
