  • 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
  • Creep parameter inversion and long-term deformation prediction of a . . .
    In the impoundment period, with a time step of 1 day, based on the historical and future water level time series, the seepage field for each time step is obtained through interpolation of the hydraulic head under characteristic water levels of EL 1640 m, 1800 m, 1840 m, and 1880 m (Chen et al , 2016a, Chen et al , 2016b) According to the
  • 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
  • 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
  • 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
  • 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
  • Identify and map coastal aquaculture ponds and their drainage and . . .
    As shown in Fig 6, during both drainage and impoundment phases, Dynamic World showed drawbacks by commonly identifying non-water as water, thus failing to accurately extract all coastal aquaculture ponds and underestimating drainage phase Furthermore, the temporal resolution of Dynamic World was lower because it was based on Sentinel-2 images
