Mining Heritage

Geotourist evaluation of thirteen small geological, geomorphological and mining heritage objects was carried out in a small v alley of the Upper Łagowica River and in its surroundings (Holy Cross Mountains, Poland). The point grading method was used, which is functional in the case of evaluation of small geotourist objects. It was shown that the analysed objects are characterized by high and medi um geotourist attractiveness. When analysed together, they strengthen their own individual values. They are suited to mark out geotourist trails ( geotrail), and additionally become a source of information about spatial changes of geodiversity. They also determine the uniqueness of this type of small river valleys of the Holy Cross Mountains on a regional and supra-regional scale. The evaluation of these objects and the proposal of a geotourist trail in the Upper Łagowica River valley may contribute to the activation of local communities and government authorities in the promotion of geoeducation and geotourism, draw their attention to the need for preservation and protection of the geodiversity of small va lleys of the Holy Cross Mountains, and, what is especially important, may give information about the investment attractiveness of the area.

A map of reconstructed Eocene physiography and drainage directions is presented for the southern Interior Plateau region, British Columbia south of 53°N. Eocene landforms are inferred from the distribution and depositional paleoenvironment of Eocene rocks and from crosscutting relationships between regional-scale geomorphology and bedrock geology of known age. Eocene drainage directions are inferred from physiography, relief, and base level elevations of the sub-Eocene unconformity and the documented distribution, provenance, and paleocurrents of early Cenozoic fluvial sediments. The Eocene landscape of the southern Interior Plateau resembled its modern counterpart, with highlands, plains, and deeply incised drainages, except regional drainage was to the north. An anabranching valley system trending west and northwest from Quesnel and Shuswap Highlands, across the Cariboo Plateau to the Fraser River valley, contained north-flowing streams from Eocene to early Quaternary time. Other valleys dating back at least to Middle Eocene time include the North Thompson valley south of Clearwater, Thompson valley from Kamloops to Spences Bridge, the valley containing Nicola Lake, Bridge River valley, and Okanagan Lake valley. During the early Cenozoic, highlands existed where the Coast Mountains are today. Southward drainage along the modern Fraser, Chilcotin, and Thompson River valleys was established after the Late Miocene.

Abstract Based on palaeobotanical analyses of organic deposits, as well as geomorphological and geological studies at four sites in various geomorphological locations in relation to tributaries of the Bzura River, the presence of traces of human activity, its intensiveness, and classification to cultural levels were analysed. A pattern of later and later settlement in areas remote from the axis of the Warsaw-Berlin streamway was observed along with the gradual introduction of settlement from river valley bottoms to watershed zones.

River valley bottoms have hydrological, geomorphological, and ecological importance and are buffers for protecting the river from upland nutrient loading coming from agriculture and other sources. They are relatively flat, low-lying areas of the terrain that are adjacent to the river and bound by increasing slopes at the transition to the uplands. These areas have under natural conditions, a groundwater table close to the soil surface. The objective of this paper is to present a stepwise GIS approach for the delineation of river valley bottom within drainage basins and use it to perform a national delineation. We developed a tool that applies a concept called cost distance accumulation with spatial data inputs consisting a river network and slope derived from a digital elevation model. We then used wetlands adjacent to rivers as a guide finding the river valley bottom boundary from the cost distance accumulation. We present results from our tool for the whole country of Denmark carrying out a validation within three selected areas. The results reveal that the tool visually performs well and delineates both confined and unconfined river valleys within the same drainage basin. We use the most common forms of wetlands (meadow and marsh) in Denmark’s river valleys known as Groundwater Dependent Ecosystems (GDE) to validate our river valley bottom delineated areas. Our delineation picks about half to two-thirds of these GDE. However, we expected this since farmers have reclaimed Denmark’s low-lying areas during the last 200 years before the first map of GDE was created. Our tool can be used as a management tool, since it can delineate an area that has been the focus of management actions to protect waterways from upland nutrient pollution.

Based on the NPP products of MODIS data, the spatial and temporal distribution characteristics of grassland NPP and its response to climatic factors in the vegetation growing season of the main river valleys in the southern slope of Qilian Mountains from 2000 to 2016 were carried out by correlation analysis and spatial interpolation. The research further provides a scientific basis for the quality evaluation of grassland ecosystems on the southern slope of Qilian Mountain and the rational use of grassland resources along the river. The results show that: (1) With the increasing distance of buffers on both sides of the river, the NPP of grassland in each year shows the characteristics of “single-peak” distribution, which is increased first and then decreased; (2) the NPP of grassland in the main river valley of the southern slope of Qilian Mountain The spatial distribution characteristics show a trend of increasing from northwest to southeast. (3) The spatial distribution of NPP and air temperature in the main river valleys of the southern slope of Qilian Mountains is gradually increasing from northwest to southeast, but the spatial distribution correlation coefficient of NPP and precipitation in the river valley grassland of vegetation growing season basically shows a trendof decreasing from northwest to southeast.

The Republic of Serbia is а continental country located in the western part of the Balkan Peninsula, in Southeast Europe. In terms of physical characteristics, Serbia is divided into two parts: Pannonian part and mountainous part. The northern part of the country is located in the valley of the Middle Danube, the Sava River valley and the Tisza River valley. In the middle part of the country, the river valleys of the Drina, the Kolubara and the Morava are located. For the purposes of this research, the authors have used the annual precipitation data from 15 meteorological stations distributed throughout the Republic of Serbia. The data from these meteorological stations for the period between 1991 and 2019 has been provided by The Serbian Institute of Meteorology and Hydrology. This data has been used to calculate the annual amount of precipitation, and the trends in annual precipitation.

Satellite-based land cover products play a crucial role in sustainability. There are several types of land cover products, such as qualitative products with discrete classes, semiquantitative products with several classes at a predetermined ratio, and quantitative products with land cover fractions. The proportions of land cover types in the grids with coarse resolution should be considered when used at the regional scale (e.g., modeling and remote sensing inversion). However, uncertainty, which varies with spatial distribution and resolution, needs to be studied further. This study used MCD12, ESA CCI, and MEaSURES VCF land cover data as indicators of qualitative, semiquantitative, and quantitative products, respectively, to explore the uncertainty of multisource land cover data. The methods of maximum area aggregation, deviation analysis, and least squares regression were used to investigate spatiotemporal changes in forests and nontree vegetation at diverse pixel resolutions across China. The results showed that the average difference in forest coverage for the three products was 8%, and the average deviation was 11.2%. For forest cover, the VCF and ESA CCI exhibited high consistency. For nontree vegetation, the ESA CCI and MODIS exhibited the lowest differences. The overall uncertainty in the temporal and spatial changes of the three products was relatively small, but there were significant differences in local areas (e.g., southeastern hills). Notably, as the spatial resolution decreased, the three products’ uncertainty decreased, and the resolution of 0.1° was the inflection point of consistency.

The study covered 10 small rivers in the North-Eastern part of the Samara Volga region. The author studied the vegetation cover, which is understood as a set of phytocoenoses and their constituent plant species. On the territory of Pokhvistnevsky District, there are two groups of river valleys that are heterogeneous in geobotanical terms. The first group includes the rivers with forested valleys (Kutlugush, Murakla, Karmalka). Their slopes are more or less symmetrical and steep. The vegetation cover of an undeveloped floodplain is usually uniform, and there is usually no belt. The valleys of the second group are treeless; their slopes are sharply asymmetrical (Amanak, Tergala, Talkish). The right-bank tributary of the Maly Kinel River the Lozovka River with its length of 20 km and the left tributary Kuvayka River with its length of 16 km were studied on the territory of Kinel-Cherkassky District. The Padovka and Zaprudka rivers and the right tributaries of the Bolshoi Kinel River (Kinelsky District) were also studied. The most common associations are (Salix fragilis heteroherbosa, Scirpus sylvaticus purum, Agrostis stolonifera Amoria repens, Elytrigia repens + Poa angustifolia heteroherbosa). In total, 19 types of phytocoenoses were noted, 4 of them are found in half of the studied rivers. In the plant communities of small river valleys there are 232 species of higher wild plants, which belong to 139 genera from 48 families. This is 60% of the total number of higher plants registered in the flora of small river valleys of the Samara Region. Rare protected plant species are registered here: Adonis volgensis Steven ex DC., Cacalia hastata L., Delphinium cuneatum Stev. ex DC., Globularia punctata Lapeyr.
