PROJECT DESCRIPTION:

The position is financed under the NCN SONATA BIS 13 project no. 2022/46/E/ST10/00266 entitled " Impact of global warming on large river sinuosity”. The position is fiannced for 48 months.

Taking advantage of free satellite images handled with Google Earth Engine, this project aims to investigate the impact that global warming has on large rivers, looking at changes in their sinuosity and the development of riparian vegetation within their banks. As lateral migration of river channels allows for connecting the main river with its floodplains, eventually controlling sediment deposition and carbon stock outside of the main current, a reduction in river sinuosity might have negative feedback on the greenhouse-gas budgets of the Earth through the competing effects of silicate weathering and organic matter degradation under a warming climate.

Existing studies correlating changes in river sinuosity with climate are limited to cold regions, as those regions are more sensitive to climate change, and are experiencing a faster rate of warming. However, a global dataset of changes in river sinuosity is still missing, and the present project will address this knowledge gap by analyzing large watercourses flowing at all latitudes.

During the project the following research questions will be addressed, and the associated hypotheses tested:

Q1: What key metrics can be used to infer trends in river sinuosity and vegetation encroachment, using free satellite imagery?

H1: Landsat data can be used to investigate long-term trends of large rivers, and common metrics (e.g., Normalized Difference Vegetation Index-NDVI, Modified Normalized Difference Water Index-MNDWI) can give reliable estimates of variations at non-detailed scales.

Q2: What key metrics can be used to infer trends in global warming, with particular reference to riverine environments?

H2: Satellite-derived indexes are reliable in providing large-scale trends of climate variables such as air temperature, soil moisture and precipitation.

Q3: Does global warming affect river sinuosity at spatiotemporal scales observable via remote sensing at all latitudes? Is 40-year (Landsat data) a sufficiently long period to observe climate-driven changes in the fluvial platform?

H3: A hotter climate is contributing to reducing overland flow and seepage discharge along channel banks, and favoring the encroachment of vegetation on floodplains and banks, therefore stabilizing and strengthening river channels, with a reduction in sinuosity. The Landsat dataset is sufficiently long (40 years) to observe changes regardless of latitude.

Q4: What are the key drivers of the decrease in river sinuosity?

H4: Global warming is not only increasing the frequency of extreme events such as floods, which are paramount in increasing river sinuosity, but also reducing normal flow, therefore allowing vegetation to encroach banks, and reducing river sinuosity.

Q5: Is it possible to relate changes observed now in the Arctic regions to changes observed in the past at lower latitudes?

H5: The reduction in river sinuosity happens across all climate zones, but its timing and magnitude are different. However, given that changes are relatively fast, it is possible to track their history and compare different climatic areas.

The project aims to creating

• - unique datasets on river sinuosity, vegetation development and global warming metrics;
• - develop free GEE algorithms and R codes to analyze satellite images and correlate river sinuosity with global warming metrics
• - a baseline for investigating the influence of global warming on fluvial geomorphology.

TASKS DESCRIPTION:

We are looking for a highly motivated PhD candidate to join our computational imaging research teams at the Institute of Geophysics, Polish Academy of Sciences. The candidate will work on using Google Earth Engine to recognize relationships between river planform morphology, changes in riparian vegetation, and global warming.

The student will be part of a solution-oriented dynamic international team created under the  NCN SONATA BIS 13 project no. 2022/46/E/ST10/00266 entitled " Impact of global warming on large river sinuosity”, and contribute to advancing the state-of-the-art in both theory and application of remote sensing in fluvial environments.

The student is expected to:

• analyze existing literature on using satellite imagery and Google Earth Engine for investigating riverine dynamics and climate change trends
• create and maintain a global dataset of satellite-related metrics and indexes on river dynamics and climate change
• analyze case studies in detail, eventually interacting with local stakeholders
• report the research results in related national and international scientific conferences
• co-author scientific articles and technical reports
