Saint-Venant's tw...

Sediment transport in basins disturbs the ecological systems of water bodies and leads to reservoir siltation. Its evaluation is crucial for managing resources. The practical application process-based model can confront some limitations noticed lower accuracy during validation process due lack reliable physical datasets. In this study, we attempt apply machine-learning-based modeling (ML) predi...

Water supply systems that use rivers with high sedimentation levels may experience issues such as reservoir siltation. The suspended sediment concentration (SSC) of experiences interannual variation and nonlinearity due to its close relationship meteorological factors, which increase the mismatch between river water source urban demand. raw system scheduling problem is expressed a pump station ...

Abstract The Yellow River (YR) is famous for its ‘hanging river’ due to the high sedimentation rate in lower reaches. Reservoir sediment retention (RSR) and water–sediment regulation (WSR) of Xiaolangdi (XLDR) contribute mitigating siltation adjusting bankfull channel geometry (LYR). However, few studies have been conducted quantify contribution RSR WSR medium-sized shaping. In this paper, we a...

All over the world, dam managers are constantly confronted with siltation of reservoirs. This natural phenomenon represents a menace to safety dam; because sediments deposited amplifies load applied and shut off dam’s bottom outlet. It also reduces usable capacity reservoir degrades quality water stored (pollution, eutrophication, turbidity, etc.). In arid semi-arid countries like Morocco, de-s...

Abstract Mining activities have significantly affected the Neotropical freshwater ichthyofauna, most diverse in world. However, no study has systematized knowledge on subject. In this review, we assembled information main impacts of mining crude oil, gold, iron, copper, and bauxite aquatic ecosystems, emphasizing fishes. The obtained shows that generate several different disturbances, mainly vi...

With the rapid development of agricultural economy, people are paying more and attention to how apply high-efficiency technologies that save resources improve production efficiency, so water-saving irrigation technology has gradually developed. China’s is relatively backward. In addition inappropriate methods systems, problems such as siltation, seepage, frost heave damage in canals have seriou...

Benthic macroinvertebrates respond to several factors characterizing the physical habitats, as water depth, current and streambed substrate. Thus, anthropogenic disturbances altering these may have different effects on benthos, also depending mesohabitats. These include sediment flushing operations, commonly carried out recover reservoir capacity, investigating their at mesohabitat scale could ...

Seagrasses cover about 0.1–0.2% of the global ocean, and develop highly productive ecosystems which fulfil a key role in the coastal ecosystem. Widespread seagrass loss results from direct human impacts, including mechanical damage (by dredging, fishing, and anchoring), eutrophication, aquaculture, siltation, effects of coastal constructions, and food web alterations; and indirect human impacts...
