Subject:
basins; dams (hydrology); models; power generation; research; river flow; rivers; water; water power; watersheds; Amazon River; Brazil
Abstract:
... Hydropower dams have received increased global attention due to their detrimental socioenvironmental ramifications. Such attention has led to an increase in studies on the impacts of reservoir operation on river flow; however, a holistic understanding of the compounded effects of hydropower dams on different hydrological characteristics is lacking, especially for large river basins such as the Ama ...

Abstract:
... Hydropower dams are associated with adverse impacts on biodiversity, yet there remains a lack of robust scientific evidence documenting the magnitude of these impacts, particularly across highly biodiverse tropical waterways. Aquatic and semi‐aquatic vertebrates are disproportionately affected by human changes to aquatic environments and hydropower expansion is an increasing threat to the Endanger ...

Abstract:
... A river is an ecosystem where fish fauna represents an important structural element. To re-establish connectivity, it is imperative to allow movement between functional habitats. Due to the hydromorphological complexity of large anthropized rivers and the lack of study techniques that can be used in such environments, relevant data with regard to fish ecology are scarce. On the River Meuse, Belgiu ...

Abstract:
... The role of fish translocation upstream of dams, for the conservation of migratory species, is controversial. An important but still unaddressed question is whether migratory patterns are affected, after the translocation events, by a hydropower dam. In existing dams, a useful means to test this might be to compare the behaviour of translocated fish with those in undammed river segments in the sam ...

With increasing upscaling factors, richer and more abundant details can progressively be obtained. However, in comparison with natural images, the complex spatial distribution of remote sensing data increases the difficulty in its reconstruction. Furthermore, most SR reconstruction methods ...

Abstract:
... Restoring active bedload transfer in human-impacted rivers has received increasing attention in recent years, notably in response to the European Water Framework Directive (WFD), which requires that the continuity of rivers not be disturbed by anthropogenic features such as dams or weirs. The Bocq River (233 km²), a moderate-gradient stream in Wallonia, Belgium, has a hydraulic resource that was f ...

Abstract:
... River-sea transition plays a key role in global geochemical cycles. The Yangtze River Estuary of China was selected as the research area, and the Section-Segmented Method was applied to determine the nutrient discharge from the Yangtze River to the East China Sea. A 3-D numerical model for the estuary was established and validated against the field investigated data. By numerical experiments the d ...

Abstract:
... The discharge and sediment loads of the Mekong River (MR) have been significantly altered because of natural processes and anthropogenic activities. We examined the impacts of dams in the MR basin on changes to the long-term discharge and sediment loads from upstream of dams in China (e.g., Jiuzhou) to the Vietnamese Mekong Delta (VMD) at daily, monthly, and annual scales over a 55-yr period (1961 ...

Abstract:
... The present study examines the extent of erosion and deposition along the banks of the lower reaches of the Krishna River (India) between 1973 and 2015, by analyzing the shifts in the bank lines using Landsat images of the years 1973, 1991 and 2015. The analysis is limited to the river segment downstream of the Nagarjuna Sagar Dam up to the Krishna Delta (318 km). The results indicated that the to ...

Abstract:
... Ecosystems provide climate-change adaptation opportunities including ecosystem services, adaptation benefits and livelihood improvement especially for natural resource dependent communities. To contribute to the understanding of location specific adaptation processes of predominantly agro-pastoralists, a study was carried out in the central cattle corridor of Uganda to characterise ecosystem-based ...
