Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 3042-3055, June 2026.
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 ...

Low sediment retention efficiency limits delta formation in tectonically confined high‐energy coastal systems

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
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

Rapid changes of the lava‐delta coastlines formed by the 2021 volcanic eruption on La Palma, Canary Islands

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
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

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
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

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
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

open access: yesGlobal Challenges, Volume 10, Issue 6, June 2026.
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 ...
