“…anthropogenic uses, such as (a) drinking water supply, (b) power supply, (c) flood protection, (d) tourism and (e) navigation (Habersack & Walling, 2013;Piégay, Cottet, & Lamouroux, 2020;Schiemer, Drescher, Hauer, & Schwarz, 2018). In order to meet the various human demands, rivers have undergone significant anthropogenic changes over recent centuries, with a loss of up to 90% of their floodplain area, compared to the original extent documented for Central and Southern Europe (e.g., the Rhine, Po, and Danube) (Drescher, 2018).…”

The Vjosa River in Albania represents one of Europe's last free-flowing wild rivers, comprising a mosaic of various habitats and forming a highly dynamic natural ecosystem for flora and fauna, that has largely disappeared from other European rivers outside of Russia. However, due to economic interests, this sensitive and heterogeneous river system is under pressure from potential future use in hydropower, threatening the good hydromorphological and ecological status of the river with reservoir flushing, hydropeaking, colmation, loss of habitats and loss of connectivity. Beside the ecological impacts, this study aims to point out the boundaries for technical and economic issues related to hydropower. Hence, for the first time, sediment transport in the Vjosa River was measured. The results indicate possible consequences of a disturbed sediment regime and loss of capacity caused by the sedimentation of reservoirs. Moreover, subsequent consequences, such as river bed incision downstream of dams as well as progressive coastal erosion, are discussed. By combining data from direct bedload and suspended sediment measurements with long-term hydrological data, an attempt is made to describe the sediment characteristics of the Vjosa catchment and evaluate potential hydropower plants and resulting reservoir sedimentation using limited data. Based on the presented study, it is aimed to define sediment monitoring standards for requested environmental impact assessments and to highlight possible negative impacts of hydropower projects across the entire Balkan region.

“…For this purpose, high-density LiDAR points and different remote sensing techniques, such as aerial photogrammetry, were used. This analysis also included morphometric variables that account for the fluvial dynamics of the system, such as the distribution of heights and slopes, relief ratios, and the sinuosity of the main stream [30][31][32].…”

Evolutionary analysis of the fluvial landscape provides relevant inputs for the environmental management of a territory, in such a way that the understanding of the dynamics of fluvial spaces becomes a preponderant factor in the definition of protection and management strategies. Although the development of geographic information systems is a step forward in the study of the landscape, it is necessary to establish methodological frameworks that make remote sensing techniques available at multiple spatio-temporal scales, especially in basins with high levels of intervention. In the present study, we develop a methodology for the analysis of the fluvial landscape development in the last century of a highly modified water body, through the detailed study of hydrogeomorphic elements, using remote sensing techniques including high-density surface data (LiDAR) and historical aerial imageries; when supported by fieldwork, these allow for the identification of the sequence of sedimentation–erosion zones, differentiating in detail the zones denominated as areas of current erosion, accretion zones, and historical erosion zones. An application of the methodology was carried out in the Larrodrigo stream, located in Salamanca, Spain.

“…At the same time, we should also support the construction of the internal water system. Traditional water systems should be preserved, while new tools for their economic viability should be designed to establish acceptable compromises between water uses and riverine ecosystem requirements (Piégay, Cottet, & Lamouroux, 2020). Water quality and flood control monitoring techniques should also be introduced to ensure water security within settlements (Poledniková & Galia, 2020).…”

With the overall improvement of China's rural settlements, the spatial form of villages has undergone dramatic changes. The Dong villages in the mountainous regions of southwest China are closely tied to rivers and have always maintained remarkable water adaptability even under the intense development and construction disturbances of the past 30 years, providing a direct model for the sustainable development of modern communities. This paper takes the Gaojin‐Bazhai valley, Guizhou Province, and the eight Dong villages in it as a case study, using multisource data such as high‐resolution historical satellite imagery, participatory spatial mapping, interviews with key figures, and ethnography, and integrates the research methods of spatial analysis and anthropological field surveys to trace village spatial development at three levels: valley, village, and building groups. The study reveals the interaction between the Dong villages and the water environment over a long time period, and reveals a coupled artificial–natural interaction mechanism with water adaptation as the core, which is specifically interpreted as restriction, induced, adjustment, and synergy effects. With the aim of promoting a more effective succession of this mechanism, we also propose policy recommendations for the development of the water environment in the river basin as a response to the challenges arising from the ecological and ethnological conflict brought by modernization and tourism.
