An experimental investigation on the flow resistance over a porous gravel-bed surface and its non-porous counterpart
Navaratnam, Christy Ushanth; Aberle, Jochen; Qin, Jie; Henry, Pierre-Yves T (Journal article; Peer reviewed, 2018)This paper presents preliminary results from laboratory experiments which were specifically designed to determine the flow resistance over a water-worked gravel-bed and its impermeable counterpart (cast-bed). The technique ... -
Assessment of random wave energy dissipation due to submerged aquatic plants in shallow water using deep water wave conditions
Myrhaug, Dag; Henry, Pierre-Yves T (Peer reviewed; Journal article, 2021)This article addresses the random wave energy dissipation due to submerged aquatic plants in shallow water based on deep water wave conditions including estimation of wave damping. The motivation is to provide a simple ... -
Beyond equilibrium: Re-evaluating physical modelling of fluvial systems to represent climate changes
Baynes, Edwin R.C.; van de Lageweg, Wietse I.; McLelland, Stuart J.; Parsons, Daniel R.; Aberle, Jochen; Dijkstra, Jasper; Henry, Pierre-Yves T; Rice, Stephen P.; Thom, Moritz; Moulin, Frederic (Journal article; Peer reviewed, 2018)The interactions between water, sediment and biology in fluvial systems are complex and driven by multiple forcing mechanisms across a range of spatial and temporal scales. In a changing climate, some meteorological drivers ... -
Experimental and Numerical Determination of the Head Loss of a Pressure Driven Flow through an Unlined Rock-Blasted Tunnel
Aberle, Jochen; Henry, Pierre-Yves T; Kleischmann, Fabian; Navaratnam, Christy Ushanth; Vold, Mari; Eikenberg, Ralph; Olsen, Nils Reidar Bøe (Peer reviewed; Journal article, 2020)The friction loss in a part of the rock-blasted unlined tunnel of the Litjfossen hydropowerplant in Norway was determined from experimental and numerical studies. Remote sensing datafrom the prototype tunnel provided the ... -
Hydraulic physical model production with Computer Numerically Controlled (CNC) manufacturing techniques
Henry, Pierre-Yves T; Aberle, Jochen; Navaratnam, Christy Ushanth; Ruther, Nils (Journal article; Peer reviewed, 2018)Physical models are a well-accepted tool in hydraulic engineering, allowing for the detailed characterisation of flow processes and the validation of structure designs with complex boundary conditions. The methods used to ... -
Influence of Gravel-Bed Porosity and Grain Orientation on Bulk Flow Resistance
Navaratnam, Christy Ushanth; Aberle, Jochen; Qin, Jie; Henry, Pierre-Yves T (Journal article; Peer reviewed, 2018)This paper presents results from experiments that were carried out to study the effect of porosity and grain orientation on flow resistance. Experiments were performed over three rough surfaces; a water-worked gravel-bed, ... -
Variability and similarities in the structural properties of two related Laminaria kelp species
Henry, Pierre-Yves T (Journal article; Peer reviewed, 2018)Kelps of the genus Laminaria have long been studied and shown to exhibit a seasonal shift in growth and morphology, as nutrients and light levels change during the year. However, the variation of kelp biomechanical properties ...
