An Experimental Study of Hydraulic Jump in a Gradually Expanding Rectangular Stilling Basin with Roughened Bed [PDF]

open access: yes, 2017
The paper presents the results of an experimental study carried out to investigate the effect of geometric and hydraulic parameters on energy dissipation and location of the hydraulic jump, with a change in the height of roughness elements and the ...

Dissipation of Hydraulic Energy by Curved Baffle Blocks [PDF]

open access: yes, 1999
Experimental evaluation of the effects of relative size, curvature and location of curved floor baffle blocks in the dissipation of energy and control of hydraulic jump is presented.

(Architectural) measures to control wave overtopping inside harbours [PDF]

open access: yes, 2012
One of the weak zones in the safety of the coastal city Oostende, Belgium, are the quays in the inner harbour which are rather low. A storm wall is an easy and effective measure to reduce wave overtopping and prevent the city from flooding.

A Review of Accidents and Failures of Stepped Spillways and Weirs [PDF]

open access: yes, 2000
Recent advances in technology have permitted the construction of large reservoirs and chutes. These developments have necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Numerical investigations of stilling basin efficiency downstream radial gates – A case study of New Assuit Barrage, Egypt [PDF]

open access: yesJournal of Water and Land Development
Radial gates are more common than vertical sluice gates for a number of reasons. They are simpler to use, cause less flow disturbance, require less lifting force, and deliver better discharge.

Simulations of snow distribution and hydrology in a mountain basin [PDF]

open access: yes, 1999
We applied a version of the Regional Hydro‐Ecologic Simulation System (RHESSys) that implements snow redistribution, elevation partitioning, and wind‐driven sublimation to Loch Vale Watershed (LVWS), an alpine‐subalpine Rocky Mountain catchment where ...

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and
