The Baihetan hydropower station is the second largest worldwide. It began to store water in April 2021. We conducted a dense hybrid gravity and GNSS survey at 223 stations, obtained free-air Bouguer anomalies, inversed lithospheric density structure, calculated isostatic additional force (IAF) borne by lithosphere reservoir area. Moreover, we studied change Coulomb stress around due impoundment...

Patterns in the temporal composition, abundance and diversity of the phytoplankton community of the Paraná river prior to and after the initial filling phase of the Yacyretá reservoir are analyzed. The study site is located 220 km downstream from the Yacyretá reservoir and 30 km downstream from the confluence with the Paraguay river. Because both rivers remain separate and unmixed at the study ...

Vanderkloof Dam was periodically sampled between November 2014 and April 2016 for a range of water quality parameters to assess the potential cage culture rainbow trout, Oncorhyncus mykiss. The dam is strongly stratified in summer autumn, although upper column temperatures remain relatively cool, largely <25°C. considered oligotrophic, characterised by phosphorus limitation primary productio...

A series of field studies were conducted to gain a better understanding of the bioaccumulation and dynamics of polychlorinated biphenyl (PCB) congeners in the aquatic food web of the Kalamazoo River flood plain. Representative species of passerine birds, mammals, fish, aquatic plants, invertebrates, and colocated sediments were collected from areas located within submerged portions of the forme...

Induced seismicity has been observed near Monticello Reservoir, South Carolina, since December 1977. Deployment of a seismic network before impoundment allowed for detection and accurate location of pursuant seismicity since its inception. Corroborative fault-plane solutions, together with geological and borehole data on fracture orientations, made it possible to determine the structures associ...

Current paradigms of reservoir ontogeny suggest that water-level fluctuations may increase sedimentary nutrient release, causing long-term eutrophication of water bodies formed by dryland flooding. Less is known of the changes in nutrient status following conversion of natural lakes into reservoirs. Here, we use historical hydrological and limnological data and paleolimnological records of sedi...

River dynamics and sediment budget play a crucial role in shaping geomorphic variability of river channels deltaic environments. Basin-scale human activities, including dam construction, induce alterations flow the downstream to delta, quantification source shift along fluvial-deltaic systems is often uncertain. This study analyzed regime changes typical sediment-laden system—the lower Yellow (...

Water resources, although renewable, are limited and threatened by climate change anthropic activities. Assessment and forecasting of these resources can provide valuable information for water resource planners. This study aims to quantify the surface water resources used for sugarcane production in sugar complexes Ferkessedougou. This is based on morphological characterization river Morri...

The Nile River stretches from south to north throughout the Basin (NRB) in Northeast Africa. Ethiopia, where Blue originates, has begun construction of Grand Ethiopian Renaissance Dam (GERD), which will be used generate electricity. However, impact GERD on land deformation caused by significant water relocation not been rigorously considered scientific research. In this study, we develop a nove...
