Project Site

In high mountain and deep river valley areas, geological materials of river valley evolution are often missing or incomplete. To address this problem, tectonic movements at project site are analyzed using mathematical statistics based on the analysis of formation and evolution history of river terraces, and then a new method to determine the thickness of river incision layers is proposed. Taking Jiata dam area at the Western Route of South-to-North Water Transfer Project in China for an example, the reliability and reasonability of the proposed method are validated through a case study.

The Impact

The growing interest in mountainous areas is accompanied by the expansion of the process of involving unique landscapes in economic circulation, which often leads to a disruption of the natural balance. Consequently, the need for a change in the inertial paradigm, reorientation of the development of society to the path of constructing a sustainable system of environmental management is becoming more acute. This idea can be realized through the creation of ecological and economic zones, which imply the implementation of the concept of landscape organization and proportionality on the basis of the conservation and functionality of mountain landscapes. Background. The main purpose of the article is to actualize the urgent need to find a compromise between the market aspirations of various categories of nature users and the system of protected areas in the mountainous zone of the Kabardino-Balkarian Republic (KBR). To achieve this goal, the following tasks were solved: identification of the peculiarities of mountain valley landscapes in relation to the concepts of "threshold" and "capacity"; analysis of the possibilities of ecological optimization of the use of functional landscapes; Евразийский Союз Ученых (ЕСУ) # 12(81), 2020                                                                  5 search for a compromise option for co-development of the main types of landscapes that are of practical importance. Methods. In accordance with the intended goal and tasks, the authors relied on the following research methods: using the cartographic method, the centers of the impact of large hazardous natural processes on functional landscapes were considered and their paragenetic connections with adjacent fragments of geosystems were analyzed; the route method made it possible to trace the indicative connections between disturbed geo-complexes and anthropogenic pressure on the mountain-valley complexes Bashil - Chegem section of the high-mountain reserve; based on the predictive method, it is recommended to impose an additional tourist and recreational function on mountain-meadow landscapes; on the basis of an experimental method, the achievement of a critical level of sparseness and death of ageold pines within the forest park landscapes of the Elbrus region was confirmed. This publication is based on theoretical and empirical studies of Russian and foreign scientists: Isachenko A.G., Kochurova B.I., Beruchashvili N.L., supplemented by the specification of the territory under consideration.

Recent Project

Mountain glaciers represent an important hydrological and touristic resource, and their recent evolution provides a dramatic evidence of climate change for the general public. Glacier inventories, quantifying glacier characteristics and evolution, are an important tool to describe and manage high mountain glacier environments and Italy has developed a long tradition in this sector. Our country was the first to provide itself with a glacier inventory, compiled by Comitato Glaciologico Italiano and CNR, showing a glacier surface of 530 km2. A recent project, coordinated by Università Statale di Milano with the support of private bodies and the cooperation of Comitato EvK2CNR and Comitato Glaciologico Italiano, led to the development of the new Italian Glacier Inventory, a national atlas produced from the analysis of color orthophotos at high resolution acquired between 2005 and 2011. The New Italian Glacier Inventory lists 903 glaciers, covering an area of 370 km2. The largest part of glacier area is located in Val d’Aosta (36.15% of the total), followed by Lombardia and South Tyrol. 84% of glaciers (considering the number of glaciers) have an area lower than 0.5 km2 and jointly account for 21% of the total glacier surface. Glaciers larger than 1 Km2 make up 9.4% of the total number, but cover 67.8% of the total glacier area. The comparison between data from the New Italian Glacier Inventory and the CGI-CNR inventory (1959-1962) shows a 30% reduction in glacier area in Italy; considering instead the World Glacier Inventory or WGI, published at the end of the ‘80s, which reported 1381 glaciers and an area of 609 km2, glacier loss sums up to 478 glaciers and an area of 239 km2 (-39%). This shrinkage has led to rapid and significant changes to high mountain landscapes, notably glacier fragmentation, an increase in deglaciated areas, the formation of proglacial lakes and the development of pioneer vegetation.

The Arun River shows antecedent characteristics but almost all tributaries show consequent characteristics. The drainage system of the Arun River Valley (ARV) is influenced by local geological structures in number of ways. The sharp bending, sudden high gradient, narrow valleys that suddenly become wide are common. In the ARV, major tributaries are of sixth order, as the order becomes higher, total number of stream segments becomes progressively smaller, but physical dimensions of the streams increase gradually. In some areas, the divides are low and indistinct, while in others they form high mountain systems. Valley deepening is affected by various factors such as- hydraulic action, corrosion/abrasion of the valley base and weathering of the stream bed increased by subsequent removal of weathered materials. Valley deepening is very high between Pisu la and the Barun Dovan; between the Num and Yamchung as well as Leguwaghat and Barachetra. Valley widening process is predominant near Kimathanka, between Tumlingtar and Surtibari and Sattare areas. The Arun River, flowing in the state of channel equilibrium condition partially modified after local recent tectonic events. In the near future there is very low risk of vast channel shifting phenomena in the valley. The paper describes major morphometrical analysis of the Arun River Valley, eastern Nepal.
