10:15 Opening
10:30-11:30 Dr. Anirban Mukhopadhyay, Kazimierz Wielki
University, Poland — The geo-dynamics of the Ganges River using Remote sensing
The Ganges River exhibits complex geomorphological dynamics driven by sediment flux variations, fluvial erosion-deposition processes, and anthropogenic modifications. This lecture employs advanced remote sensing techniques, including Synthetic Aperture Radar (SAR) interferometry for detecting sub-pixel-scale riverbank erosion and multi-temporal optical and microwave satellite datasets for high-resolution floodplain analysis. Geospatial machine learning algorithms, such as random forest and convolutional neural networks (CNNs), are integrated with hydrodynamic models to assess sediment transport pathways and predict future channel migration trends. Furthermore, time-series analysis of Landsat and Sentinel imagery, coupled with spectral indices like the Normalized Difference Water Index (NDWI) and Modified Normalized Difference Suspended Sediment Index (MNDSSI), facilitates the quantification of sediment-laden water dispersion. By leveraging these cutting-edge techniques, we enhance the precision of spatiotemporal assessments of the Ganges’ hydro-geomorphic evolution, supporting sustainable river basin management and resilience planning.

10:00-11:30 Prof. Sergey Chalov, Kristina Prokopeva, LMSU, Russia — Remote sensing modelling of large river suspended sediment transport: introduction to GEE tools and applications
In this lecture we will discuss remote sensing approach to derive water surface reflectance from continuous time series of Landsat and Sentinel images and how to calibrate it with the onsite field measurements of suspended sediment concentration. Most of the procedures rely on Google Earth Engine (GEE) applications and codes. Based on examples from Lena, Kolyma, Selenga rivers we will capture seasonal variability of suspended sediment changes over anabranching channels and deltas, build a maps of suspended sediment concentration over extended river reaches for the period from 1989.

09:00-10:00 Dr. Alexander Osadchiev, Institute of Oceanology, Russia — Satellite monitoring and numerical modelling of river-borne sediments in coastal sea
This lecture will be focused on spreading of river discharge in the coastal sea associated with formation of river plumes. Initial spreading of river-borne suspended sediments (as well as all dissolved and floating river-borne material) after it is emerged from river to sea is governed by dynamics of river plumes. Complex dynamics of river plumes is governed by interaction of estuarine, atmospheric and ocean forcing. In this lecture, we will discuss usage of remote sensing (satellite and aerial) for detection of river plumes in coastal sea and will consider their synoptic and seasonal variability. Finally, we will touch numerical modelling of delivery and fate of river-borne sediments in coastal sea.

16:00-17:00 Prof. Edgardo Latrubesse, Federal University of Goiás-UFG-Brazil — Remote sensing of sediments applied to hydro-geomorphic studies in large rivers.
The lecture focuses on remote sensing from a hydro-morphological perspective and how it is applied to sediment transport in large fluvial systems and related processes and landforms. It will present methods and techniques on sediment budgets, channel morphologies, channel-floodplain interactions, hydro-sedimentary connectivity, confluences, and hydro-geomorphological mapping, discussing examples and results from several large rivers around the world.
