Hydromorphological processes in aquatic environments such as rivers, estuaries as well as lakes and reservoirs, include entrainment, transport, deposition and sorting processes which are key features for various research disciplines, e.g. geomorphology and paleoclimatology or hydraulics and river engineering. An accurate evaluation of entrainment, transport and deposition transport rates as well as limited supply processes like e.g. scouring or grain sorting, effecting channel morphology and bed composition, is fundamental for an adequate development of conceptual sediment budget models and for the calibration and validation of numerical tools. With improved algorithms as well as an increasing computational power, it became feasible to simulate the interaction of water, sediments and air (multiphase flows) with high resolution in space and time. In addition, with an increasing quantity and quality of validation and verification data, both from laboratory experiments and field studies, numerical models become more accurate and it is possible to gain new insight in complex physical processes, e.g. dune development, river bed armoring or density driven transport.

The main goal of this session is to bring together the community of scientists, scholars and engineers, investigating, teaching and applying novel measurement techniques, monitoring concepts and numerical models, which are crucial to determine sedimentary and hydro-morphological processes in rivers, lakes and reservoirs, estuaries as well as in coastal and maritime environments. Within the focus of this session are the evaluation, quantification and modelling of bed load and suspended load, flocculation, settling, and re-suspension/erosion of such processes relevant to morphological channel changes as bed form development, horizontal channel migration, bed armouring and colmation.

Public information:
Welcome to our EGU online session
HS9.3/GM2.11 Measurements, monitoring and modelling of hydro-morphological processes in open-water environments.

As the format of presenting our research content in a chat is quite new to all of us, we would like to provide some brief information which will be updated on Tuesday evening, according to the response of the authors we got until then.

Our chat session is divided into two sections ( Wed, 06 May, 10:45–12:30 and Wed, 06 May, 14:00–15:45).
There are already many presentations uploaded, some are also open for discussion already. Please feel free to use this option and also check out the presentations prior to the chat session. If possible, prepare your questions in advance so that you can quickly copy / paste them when it is time to do so.

Every author who is interested to participate in the chat will be given a slot where she / he can briefly introduce the work and then answer questions.
The Displays will be presented in the same order as their numbering. Based on the feedback from the authors we set up a rough schedule, which you can find in the document "session material". Please be aware that some spontaneous adaptions might be needed.

Regarding the chat itself:
• All authors have the possibility to introduce their work in 3-4 sentences first. Then we will ask the participants to start with their questions.
• If possible, attendees should prepare their questions in advance so that you can copy / paste them
• For questions: please start your answer by @authorname. If it is related to the display, please indicate the slide's number. That will help to keep track of the discussion.
• When the timeslot is over there is still the possibility to ask / answer questions in the general EGU chat (instead of the session chat).
• The session chat is NOT recorded / stored anywhere.
• Do not forget to use the comment 's function on EGU2020 website .
• Please keep polite and patient, as we might face some technical issues, this procedure is quite new to al

Thanks a lot for your interest and hope to chat with you on Wednesday
