The PhD work will be developed in the context of the project “Towards a new understanding of fluvial ecosystems : integrating wood regime across multiple scales“, foudend by the SNSF Eccellenza Professional Fellowship Program.
Instream wood (i.e., downed trees, trunk, rootwads and branches, usually >1 m in length and >10 cm in diameter) significantly influences river morphology and sediment dynamics, and it plays an important role in supporting biodiversity, influencing the nutrient cycle, and providing a variety of physical habitats. Moreover, instream wood is an important element of the organic carbon budget. However, the transport of large quantities of instream wood during floods may enhance related damages. Instream wood research has grown considerably over the last years, but important gaps still exist. This project will address some of the most important ones.
In particular for this position the candidate will focus on where does wood come from, and hos is stored in the river network.
The PhD project aims at :
- Assessing instream wood characteristics alond different alpine rivers
- Studying the influence that different riparian forest stands has on instream wood characteristics distribution
- Infering wood origin by applying dendrochemistry and fingerprinting at the watershed scale
