Biography
Dr. László Bertalan is an Assistant Professor at the Department of Physical Geography and Geoinformatics, University of Debrecen, Hungary.
I have received my PhD degree in Earth Sciences in 2020. My research activities are mainly focusing on fluvial geomorphology, river channel morphodynamics, bank erosion. Mainly, I use Uncrewed Aerial Systems (UAS) - or with other words: drones - for high-resolution aerial mapping.
I use UAS technology for the better understanding of fluvial, environmental, agricultural or even urban processes.

Keynote talk in Beijing
I have received a very honorable invitation from Changlin Wang, Secretary General of the International Society for Digital Earth and Professor at the Chinese Academy of Sciences, to give a keynote talk about our drone mapping research at the 1st Youth Innovation Forum in Beijing, China.
Great hospitality, excellent young scientists, great food, an everlasting experience! 🙂

ISDE Symposium 2023
We are attending the 13rd International Symposium of International Society for Digital Earth in Athens, Greece. Exciting event to discuss the most novel Earth observation and data analytics methods (i.e. Big Earth Data) within this nice society to achieve SDGs.
The Young Scientist Innovation Network within the framework of International Society for Digital Earth has just been launched in May. Details: http://www.digitalearth-isde.org/show-48-265-1.html
It was great to meet with some of my fellow Committee Members in person at the symposium.
Exciting work is ahead within this initiative.
Annual field work
As part of the preparation for the exam period, we visited the Sajó River with foreign students of my Fluvial Geomorphology course, where we examined the landforms and floodplain structure typical of alluvial rivers. Due to the overpass of the recent flood peak of the Sajó River, we had the opportunity to observe bankfull channel conditions. As a particular interest, during our visit, we also observed the continuous collapse of the river banks on the outer banks of the meanders.
Meeting with colleagues from India
EGU General Assembly brings together scientists of common interest not just from Europe!
It was great to meet finally Professor Kamal Jain (IIT Roorkee) and his PhD student Vishal Mishra from India.
We will start new collaborations using drones in geomatics.
EGU 2023
It is always the key event of the year to attend the General Assembly of the European Geosciences Union in Vienna.
We have organized the 'regular' Fluvial Systems session with great interest from attendees.

International Geomorphology Week 2023
I have participated at the International Geomorphology Week Webinar series (Eastern Europe) organized by the IAG (International Association of Geomorphologists).
My talk summarized our recent UAV-based methods for high-resolution hydromorphological mapping.
New role within ISDE
I am starting a new role as a Committee Member of the Young Scientist Innovation Network (YSIN) within the framework of International Society fo Digital Earth (ISDE).
Details soon...
Academy talks
I gave two talks about 1) novel hydromorphological mapping tools and 2) drone-based soil moisture estimation of agricultural parcels during the Celebration of Hungarian Science at the headquarters of the Hungarian Academy of Sciences in Budapest.
New book chapter published
After five years of intense activities carried out within the HARMONIOUS COST Action, the book “Unmanned Aerial Systems for Monitoring Soil, Vegetation, and Riverine Environments” is published. The book aims to share the experience gained and to provide guidance for all those that are willing to approach the use of UAS-based environmental applications. We have dedicated one specific chapter for mapping river channel dynamics too.
Autumn of Experts vol.02.
Another great memory from this field season when we hosted Hervé Piégay and Joe Wheaton along the Sajó River in Hungary. Joint research paper is on the way! We also had a field trip organized by Miloš Rusnák (Slovak Academy of Sciences) along the Belá River too.
Radio Report on my research
I have been invited to give an interview about my research on river hydromorphology at our university's radio channel, FM90 Campus Radio. It was fun! :)
Here is the recording (Hungarian only):
Abstract submission is now open for #EGU23
https://meetingorganizer.copernicus.org/EGU23/session/47017
We're leading our 'traditional' fluvial session to hear about your amazing researches about rivers, floodplains, sediments! :)
Autumn of Experts vol.01.
What an influencing fall during my fieldwork season! It was an absolute pleasure to host the legendary Prof. Gary Parker (University of Illinois Urbana-Champaign) and Dr. Jeffrey Nittrouer (Texas Tech University) from USA at Sajó River and discuss many things on my research and meandering channel morphodynamics. Thanks for the opportunity from Dr. Gergely Török (Budapest University of Technology and Economics).
