Spatial-temporal evolution of landslides spanning the impoundment of . . . The impoundment began in April 2021 and raised the water level by more than 165 m within six months, triggering many new and accelerating old landslides, such as the Wangjiashan landslide (Chen et al , 2023), the Wulipo landslide (Shi et al , 2023), and the Tuandigou landslide (Cheng et al , 2023) The formation of these new landslides is
Impoundment-induced stoichiometric imbalance exacerbated phosphorus . . . Nonetheless, research remains relatively limited on phytoplankton limiting factors and nutrient stoichiometry interactions in subtropical impoundment reservoirs This study fills a critical gap in the current research by providing a comprehensive assessment of the influences of N and P on phytoplankton biomass in Lake Qiandaohu, China
Mitigating adverse impacts of reservoir impoundment on lake ecology: A . . . However, the impoundment of the reservoirs reduces the release during the impoundment period and directly alters the runoff, sediment, and water quality in downstream rivers, which have become a most critical factor that leads to the decline of lake resources and threaten the ecological health of lakes (Liu et al , 2017; Zhang et al , 2020
Anthropogenic sediment retention: major global impact from registered . . . The accumulated impoundment capacity of the LRs analyzed here is nearly 5000 km 3 (Table 2), which is noteworthy from the standpoint of representing more than four times the mean instantaneous standing stock of water held globally by river networks without impoundment (Covich, 1993) Mean, discharge-weighted residence time change for the 633
Response of a landslide to reservoir impoundment in model tests The influences of reservoir impoundment on the thrust load, time to failure, deformation pattern, and slip surfaces within the landslide were measured and are presented The results of soil pressure measurements were helpful in detecting progressive soil movements within the landslide and for obtaining the slip surface location
Investigating the hydrodynamic and biogeochemical evolutions of the . . . Before impoundment, the riverbed elevation and multi-year average river level in the dam site area are around 357 m and 370–395 m, respectively After impoundment, the upstream reservoir and downstream river levels are between 540–600 m and 370–390 m, respectively
Reservoir impoundment alters surrounding plant physiological activities . . . For reservoir engineering impoundment, there will be variations in fog conditions before and after impoundment, which may potentially influence the 18 O enrichment of plant leaves Additionally, sunlight and the atmosphere and CO 2 concentrations are also the most important factors influencing the plant physiological activities ( Siegwolf et al
Carbon footprints of pre-impoundment clearance on reservoir flooded . . . Pre-impoundment clearance of a reservoir area to be flooded is a commonly applied engineering measure in the site-preparation phase of dam construction, particularly in large hydro-projects In most cases, pre-impoundment clearance refers to the removal of vegetation such as trees and shrubs in areas to be flooded
Catastrophic mass flows resulting from tailings impoundment failures . . . Helicopter videos of the impoundment captured 8 h after failure showed active sheet erosion of tailings, dendritic drainage channels and cirque-like arcuate headscarps (Fig 6; Morgenstern et al , 2015) As the steep scarps kept migrating headward due to fluvial erosion, the height drop in the headscarp enhanced pond drainage from farther ends
Macroinvertebrate community responses to river impoundment at multiple . . . River impoundment by the construction of dams and the creation of reservoirs is considered one of the most significant forms of river regulation (Petts, 1984; Zarfl et al , 2015) Today, there are an estimated 58,500 large dams (higher than 15 m) worldwide (ICOLD, 2017)
