The importance of granular processes and segregation in geophysical flows
December 5, 2017
Ms. Sally FENG

Dear Colleagues,


Please consider submitting an abstract to the session GM1.5 (co-organized HS11.17/NH1.22/SSP3.18),


The importance of granular processes and segregation in geophysical flows: implications for landscape evolution and hazard analysis (co-organized)

                Convener: Philippe Frey  | Co-Conveners: Nico Gray , Alexandre Valance


at the forthcoming EGU General Assembly taking place in April, 8-13, 2018 in Vienna, Austria.


The deadline for the receipt of abstracts is 10 Jan 2018, 13:00 CET


The abstract for the session  follows:


Modelling of Earth and planetary surface processes from channel dynamics to erosion of landscapes has made good use of the continuum framework, rather than directly dealing with particle scale processes, partly because of the typical large scale of the problem. Experiments, field observations, and modelling have shown the dynamics of discrete particle interactions, sometimes referred to as ‘granular physics’, plays an important role in erosion, transport, deposition and more generally in the evolution of landscapes and hazard analysis.
In particular, segregation by size, density and other properties largely modifies fluxes and results in complex patterns observed in many geophysical flows and landscapes. Examples include in fluvial geomorphology, armouring, downstream fining and drastic change in bedload and suspended sediment transport ; in debris flows, the coarsening of the front and levees ; and in Aeolian transport the internal structure of dune fields. Segregation also plays a role in hazards associated with snow avalanches, pyroclastic flows, rock avalanches, gravity currents and other geomorphic flows.
This session welcomes experimental, theoretical, numerical and field-based contributions within different environments, including coasts, estuaries, rivers, mountains enhancing our understanding of granular processes as well as their upscaling into continuum-like frameworks able of representing large-scale systems.

EGU session on Measurement and monitoring techniques for sedimentary and hydro-morphological process
December 1, 2017
Ms. Estíbaliz Serrano
Dear Colleagues,

For the fourth time in a row, we are organizing a session on Measurement and monitoring techniques for sedimentary and hydro-morphological processes in open-water environments. As made in the past years very successfully, we want to bring together researchers and practitioners as well as developers for open discussions on state-of-the-art measuring instrumentation and methods. A solicited talk will be announced soon and a special issue in a peer-reviewed journal, composed by a selection of the abstracts from the 2017 and 2018 sessions, is under negotiation.

We invite you to submit an abstract to our session until 10th January 2018. Details on the session can be found here:

HS9.1/GM8.10 :: Measurement and monitoring techniques for sedimentary and hydro-morphological processes in open-water environments 

Convener: Mário J. Franca   
 Kordula Schwarzwälder, Nils Rüther, Stefan Haun, Axel Winterscheid, Stephan Dietrich, Stefan Achleitner

As before, we co-organize a sister session on Numerical modelling of hydro-morphological processes in open water environments. We invite you also to consider submitting an abstract to this session which will tentatively be held back-to-back with the first one, promoting thus the interaction of both strongly related fields of research.
Session HS9.2/GM8.9 :: Numerical modelling of hydro-morphological processes in open water environments

PhD Studentship in Hydro-environmental Research Centre at Cardiff University, UK
December 1, 2017
Ms. Estíbaliz Serrano

This PhD project will focus on research in the areas of computational fluid dynamics (CFD) for interfacial and multiphase flows in environmental & industrial applications. Research areas include two-phase interfacial flows with interface capturing method (Volume of Fluid, Level set, and combination of both), turbulence modelling using large-eddy simulation, complex geometries with immersed boundary and Cartesian cut-cell methods, and fluid-structure interaction with single/multiple body motions of six-degrees of freedom. In-house codes will be refined and applied to civil and mechanical engineering applications such as turbulent breaking waves for coastal hydrodynamics, wind-wave-current impact on floating bodies for marine renewable energy, or turbulent open-channel flows over deformable bedforms. 

The PhD project will be supervised by Dr Zhihua Xie and Professor Thorsten Stoesser. Potential candidates should contact Dr Zhihua Xie (zxie@cardiff.ac.uk) to discuss the project in the first instance. The studentship is open to Home and EU candidates. However, international students can be recommended for Vice-Chancellor's International Scholarship for Research Excellence and China Scholarship Council  at Cardiff University.

Special Issue on "Beyond the Channel—Investigating Processes at Crucial Fluvial Interfaces"
November 30, 2017
Ms. Sally FENG

Dear colleagues,

The journal Geosciences (an open-assess journal indexed by Scopus, ESCI (formerly Web of Science), etc. ISSN 2076-3263) is currently running a Special Issue entitled "Beyond the Channel—Investigating Processes at Crucial Fluvial Interfaces".
http://www.mdpi.com/journal/geosciences/special_issues/fluvial_interfaces .

Due to climate change and anthropogenic impacts, many rivers worldwide have experienced regime shifts in fluvial processes, which often affects their health and delivery of services. Complementary to flow and sediment regimes in the main channel, several processes of paramount importance are occurring at the environment interfaces such as the air-water, water-sediment, water-vegetation, and freshwater-seawater interfaces. The overall goal of this Special Issue of Geosciences is to explore the processes at these crucial interfaces of the fluvial environment, that also play important role in river geomorphology and in maintaining the health and functioning of rivers and interfacing ecosystems. For this Special Issue papers reporting theoretical, observational, experimental, and numerical investigations on these processes as well as on their implications for river management and restoration are welcome.

This special issue aims to cover, without being limited to, the following areas:
• gas-transfer at free-surface;
• sediment transport and morphodynamics in streams and rivers;
• hyporheic fluxes;
• flows at river confluences;
• vegetated flows;
• estuarine hydrodynamics and morphodynamics;
• riverine eco-hydraulics.

Please feel free to contact us if you would like to contribute a paper for this special issue. The submission deadline is 30 June 2018. You may send your manuscript now or up until the deadline. Submitted papers should not be under consideration for publication elsewhere. Manuscripts should be submitted through the online manuscript submission and editorial system at:

We look forward to hearing from you.


Best regards,

Investigation of sediment transport processes due to geophysical flows (co-organized)


Dear colleague,

we would wish to draw your attention to a session on the "Investigation of sediment transport processes due to geophysical flows", at the forthcoming EGU General Assembly, to be held in Vienna, 8-13 April 2018.


The session focuses on a broad range of applications of geophysical (specifically fluvial, coastal and aeolian) flows, as well as flows around built infrastructure. It aims to shed light into the dynamics of transport processes of earth material due to the action of turbulent flows, addressing some of the most fundamental problems in water/hydraulic engineering, hydro-geomorphological sciences and earth-surface research.


We are looking forward to welcoming any presentations relevant to the above theme. 


Please note the deadline for abstract submission is on the 10th of January 2018.


Looking forward to seeing you at the EGU18!
