Coastal embankments often collapse due to the tremendous destructive energy of an overtopping tsunami flow a deep scour by nappe flow. Hence, clarify formation condition overtopping, series tests were carried out within laboratory flume with immobile settings lowering downstream surface angle embankment model while keeping upstream slope constant (1:1) five non-dimensional depths and six differ...

A labyrinth weir allows for higher discharge capacity than conventional linear weirs, especially at low hydraulic heads. In fact, this is an alternative the design or rehabilitation of spillways. It can even be used as a strategy in problems related to dam safety. sequential method based on optimal geometric parameters and results flow analysis using Computational Fluid Dynamics experimental st...

Based on the LA-ICP-MS U-Pb zircon ages of four metamorphic samples, we discuss geochronology and provenance Guadaiza nappe, an allochthonous unit that underlies Ronda peridotites (Betic Cordilleras, Spain). The nappe is composed Triassic marbles overlying a metapelitic sequence with schists migmatites. Zircons from quartzite interlayered yield maximum depositional age ca. 289 Ma supports age. ...

new structural, metamorphic, finite strain and kinematic vorticity data for granitic gneiss and metavolcano-sedimentary rocks of thetanumaharea in the arabian shield in saudi arabia reveal a history of deformation reflecting different tectonic regimes. kinematic analysis shows their relationship to the nappe contacts between the granitic gneiss and metavolcano-sedimentary rocks and explains the...
