Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

Conceptual framework showing how tectonic confinement, steep monsoon‐driven river dynamics, high‐energy coastal processes and offshore sediment dispersal together limit sediment retention at the Narmada–Tapi river mouths, suppressing sustained subaerial delta formation despite high sediment supply. Abstract Although deltaic growth is commonly linked to

A new coastline formed during the 2021 eruption of La Palma quickly eroded, becoming crenellated and with pocket beaches, then retreated more gradually as resistant interiors of the lava were exposed. In contrast, a second thicker lava delta changed more gradually, highlighting the importance of lithology to coastal erosion.

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

Advanced Strategies of Salt Blocking in the Hypersaline Water
Advanced strategies of salt blocking in hypersaline water—including hydrophobic, unidirectional brine transportation, dissolution migration, edge crystallization, siphon capillary effect, and zwitterionic effect. ABSTRACT In the past decade, due to high consumption of freshwater and severe drought on the earth, human beings have experienced an ...
