Landscapes Live
EGU-GM Online Seminars in Geomorphology
Embedded Files
Landscapes Live is a weekly online seminar series freely accessible to the international scientific community interested in various aspects of geomorphology. Our talks take place on Zoom every Thursday, starting at 4pm time of Paris/Berlin/Amsterdam. Check your local time here.
Landscapes Live is affiliated to the Geomorphology (GM) division of EGU and contribute to develop its virtual activities. Indeed, EGU is pioneering a new CampFire concept to bring together the geoscience community in between General Assemblies. We hope that this helps us in our transition to a greener future and ensure that our community better serve the needs of all scientists regardless of international mobility.

Land is mostly diffusive and eroding: global studies of source-to-sink and geomorphic process domains
While geomorphology and sedimentology have historically characterized local-to-regional scale systems, the geospatial data revolution and computational advances now allow us to consider problems on global scales. In this talk, I will present two new tests of old community hypotheses. Firstly, open many introductory Earth science textbooks and you will see Earth’s surface depicted as a source-to-sink profile. However, despite the importance of this paradigm, we had not tested whether the modern Earth actually resembles classic source-to-sink conceptual models. We produced a global database of Earth’s source-to-sink systems and showed that Earth’s land area is mostly erosional (59%), with bypass (22%) and depositional (19%) domains less common and large parts of the world not describable by the source-to-sink model. Even in areas that do resemble the classic textbook progression, there is exceptional variability between catchments and down the world’s major rivers. While the source-to-sink paradigm remains useful, as it stands it cannot describe the sedimentologically inactive areas that make up much of the world.
Secondly, landscape evolution models use mass transport functions to model the sediment erosion, transport, and deposition processes that shape Earth’s dynamic surface. However, most models represent only two processes: diffusive soil creep and bedrock river incision. Moreover, it is unknown if these two processes alone can represent Earth’s evolution. We mapped the global distribution of geomorphic process domains and found that ¾ of land is soil-mantled hillslopes or flatlands. While both can likely be represented by diffusive soil creep, flatlands are understudied and have no accepted transport functions. The other domains (glacial, lacustrine, alluvial riverine, aeolian, and bedrock hillslope) make up little of Earth’s land area but most of its annual mass flux to oceans. This work provides a roadmap toward global Earth surface models with more representative geomorphic process domains for Earth’s past, present, and future.
