UNIL is a leading international teaching and research institution, with over 5,000 employees and 15,500 students split between its Dorigny campus, CHUV and Epalinges. As an employer, UNIL encourages excellence, individual recognition and responsibility.


To complete the team, the Institute of earth surface dynamics of the Faculty of geosciences and environment is looking for a PhD student on Instream wood dynamics monitoring.

Job information

Expected start date in position : 01.08.2020 (approximately, flexible)

Contract length : 1 year, renewable 1 x 3 years, maximum 4 years

Activity rate : 100%

Workplace : Lausanne-Mouline (Géopolis)

Your responsibilities

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“, fouded by the SNSF Eccellenza Professorial Fellowship Program.

Instream wood (i.e., downed trees, trunks, 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, 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 gathering direct/field observations of instream wood dynamics by establishing a network of cameras and tracking devices in several alpine rivers.

The PhD project will answer the following research questions :

  • What are the most suitable wood mobility monitoring techniques ?
  • How much instream wood is stored in Swiss rivers ? What is the residence time of instream wood in Swiss rivers ?
  • How is wood mobility in Swiss rivers ? What are the geomorphic characteristics of channel reaches that exhibit high wood dynamics ?
Your qualifications

The chosen candidate will have a master’s degree in geosciences, environmental sciences, physical geography, engineering or a related domain.

A requirement for this position is a good base in fluvial processes (e.g., sediment dynamics) and fluvial geomorphology. The work will require fieldwork in selected rivers in Switzerland.

Knowledge in geomorphic processes monitoring, statistics, GIS, and remote sensing are advantages.

Candidates will be committed to conducting a PhD thesis on instream wood dynamics.

Excellent skills in written and oral English are required.

What the position offers you

We offer a nice working place in a multicultural, diverse and dynamic academic environment. Opportunities for professional training, a lot of activities and other benefits to discover.
