From Extension to Strike‐Slip Faulting Along the Western Continuation of the North Anatolian Fault in the Northern Aegean Sea: Structural, Geochronological and Geochemical Constraints

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

Influences of sedimentation on overflow properties of sharp-crested weir

International Journal of Sediment Research
A sharp-crested weir is the simplest type of weir and is mainly used for discharge measurement in open channels. The surface profile of an ogee weir also is designed based on the lower nappe profile of the free jet passing over a sharp-crested weir.

Polycyclic Metamorphism, Exhumation, and Recycling of Subduction Complex Rocks, Cedros Island, Baja California

Tectonics, Volume 45, Issue 4, April 2026.
Abstract High‐pressure rocks from subduction complexes are key records of the physical and chemical processes that operate on the subduction interface, but interpretation of these records requires accurate structural understanding of where they formed in the subduction zone and the mechanisms by which they were exhumed. We present new geologic mapping,

Hydrochemical characteristic and karst development in typical karst spring area, Northern China

Frontiers in Environmental Science
Karst aquifer is controlled by complex tectonics. While the tectonic effects and its relationship with chemical evolution in large-scale karst areas are always be neglected.

The calibration of sharp-crested weirs with a horizontal edge used for measuring flows in partially full pipes [PDF]

Journal of Water and Land Development
This paper presents the results of a laboratory study on the discharge capacity of sharp-crested weirs fitted with a horizontal edge in pipes during open-channel flow conditions and clean water used to measure the outflow.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, Volume 55, Issue 2, Page 517-541, April 2026.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Numerical visualization of nappe oscillation

, 2015
The unsteady global dynamics of a gravitational liquid sheet interacting with a onesided adjacent air enclosure, typically referred to as nappe oscillation, is addressed, under the assumptions of potential flow and presence of surface tension effects ...

Frequencies of Nappe Vibration for Free-overfall Structures

, 2016
peer reviewedUnder relatively low-head discharges, the occurrence of nappe oscillation, otherwise known as nappe vibration, may be observed on hydraulic structures with a free overfall, such as weirs, crest gates and fountains. This phenomenon, which has
