Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)
Journal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

The Tromsø Nappe Contact with the Nakkedal Nappe Complex NE of Tromsdalstind : Shear kinematics and relationship with metamorphism. [PDF]
, 2011 The tectonic contact between the Nakkedal Nappe Complex and the Tromsø Nappe crops out NE of Tromsdalstind, 5 km E of Tromsø, Norway. Petrological- and structural analysis of the contact have been undertaken in order to contribute to a better ...

Nappe flow regime energy loss in stepped chutes equipped with reverse inclined steps: experimental development [PDF]
, 2015 With advances in technology and the invention of the Roller-Compacted Concrete (R.C.C) technique, stepped spillway construction has become much faster than in the past. Due to this, designers have become more interested in using this kind of chute as one

Mitigation investigation of flow-induced vibrations at a rehabilitated spillway [PDF]
, 2014 Linville Land Harbor Dam was recently rehabilitated and provided with a labyrinth spillway to increase flood passage capacity. Nappe vibration, a condition that can occur at hydraulic structures with a free overfall, has been observed for low flows.

GeogacetaThe study of fracturing at Ain Bouchermou, Ain Maârouf, and Ain Boujaoui water sources used satellite image analysis, isobase analysis, and structural field study to reveal new data on hydrological flows and water storage in karsts and breccias. Mapping the fracture network identified three groups of oriented fractures: N-S, NESW, and NW-SE, with the ...

Causes and Countermeasures for Nappe Oscillation: An Experimental Approach
, 2014 Weirs are commonly used as spillways to release flows from a reservoir. The freefalling jet on the downstream side of the weir is called the nappe. Under certain hydraulic conditions, determined mainly by the size, design, and construction of the weir ...

Quantification of nitrate removal by a flooded alluvial zone in the Ill floodplain (Eastern France) [PDF]
, 1999 The nitrate reducing capacity of a flooded system in the Ill floodplain (Eastern France) was investigated for a period of 2 years. The methodology used consisted of a spatio-temporal monitoring of stream flow and nitrate concentrations in the groundwater

Global dynamics analysis of nappe oscillation
, 2014 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 absence of surface tension effects ...
