When rivers kiss the valley walls...

IAS Visiting Fellow Dr Jens Martin Turowski delivers a seminar on their research -

The width of channel belts and fluvial valleys and its temporal evolution is important for the hydraulics, hydrology, and ecology of landscapes, and for human activities such as farming, protecting infrastructure, and natural hazard mitigation. The width of a fluvial valley is set by the river undercutting valley walls and evacuating the resulting sediment. We have recently developed a model for the temporal evolution and steady-state valley width on the assumption of a non-standard one-dimensional random walk of channel migration. The model connects valley evolution to reach-scale hydraulic parameters. Here, I introduce the model and summarize some key results and compare model predictions to observations of natural and experimental rivers.

Arrivals from 11:45 am for a 12:00 noon start. For those joining in-person, lunch will be served after the seminar from 1:00pm.

This event is hybrid format, please use the required booking button at the bottom of the page to choose either in-person or online attendance.
(Please note that in-person spaces are limited and booking is required, so we can manage numbers for catering and also the space in the seminar room)

By booking a place at this event, attendees agree to behave in a respectful manner such that everyone feels comfortable contributing as they wish. The IAS reserves the right to eject anyone who does not abide by this policy.

IAS seminars are typically recorded, minus any Q&A sessions at the end, again to encourage contributions. The recordings are then uploaded to our website on a Fellows bio page and/or Programme page, along with our IAS YouTube Channel. If you are not able to attend a seminar live, please do still register as we will email everyone who registered to let them know once the recordings are made available.
