Doctoral Student in Forest Management Effects on Water Quality / Doctoral Studentess in Forest Management Effects on Water Quality

Doctoral Student in Forest Management Effects on Water Quality

100%, Zurich, fixed-term

The student will be hosted between the groups WaldLab Ecohydrology and Silviculture. The WaldLab Ecohydrology group is part of the Chair of Hydrology and River System Science at the ETH Zurich Institute of Environmental Engineering, with expertise in water chemistry assessments in forested ecosystems. The Silviculture group is part of the Chair of Forest Resources Management at the ETH Zurich Institute of Terrestrial Ecosystems, with expertise in silviculture and forest management. We are seeking a reliable, enthusiastic, and highly motivated doctoral student with a passion for interdisciplinary science to join our team.

Project Background

This position is part of the project "Forest Management and Drinking Water Security under Climate Change," supported by the Swiss Federal Office for the Environment. The project investigates the critical link between forest ecosystem management and health and the quality of drinking water across Switzerland. As climate change intensifies disturbances like droughts, windthrows, and pest outbreaks, understanding how forest structure and management influence water quality outcomes is vital. Across national scales and experimental sites, the project integrates country-wide data analysis, water quality monitoring of spring networks, and detailed mechanistic insights into subsurface flow routing and transit times. The project is closely aligned with forest and drinking water stakeholders and decision-making authorities; thus, a solid understanding of Central European and Swiss forest ecosystems, including species composition, development stages, and silvicultural practices, is essential for this role. The project will be conducted in a collaborative environment between the two research groups, providing extensive technical support and interdisciplinary expertise in ecohydrology and forest management.

Job Description

The doctoral project focuses on assessing the resilience of Swiss drinking water resources to forest changes and management interventions. As the successful candidate, your responsibilities will include:

• National-Scale Data Integration: Analyzing gradients in forest cover and structure (e.g., tree species mixtures, density) in relation to long-term drinking water parameters, accounting for hydrogeology and land-use history.
• Field Monitoring & Sampling: Conducting water quality assessments across Swiss-wide spring networks to identify how management practices influence resilience during event-driven disturbances.
• Mechanistic Investigations: Monitoring intensively instrumented experimental sites to determine how forest health and structure alter subsurface flow routing and contamination pulses.
• Synthesis & Strategy Development: Developing and evaluating suitable management strategies to reduce drinking water risks.
• Stakeholder Communication: Performing statistical analyses and modeling to translate findings into actionable management recommendations for water abstractions.

The full-time position is funded for four years. Salary and social benefits are provided according to ETH Zurich rules.

Profile

The ideal candidate will have completed a Master's degree in hydrology, environmental sciences, forest sciences, ecology, or a closely related field, with experience in water chemistry, silviculture, experimental field work, and large-scale data analysis. You should possess strong statistical skills and programming experience (e.g., in R or Python). Proficiency in written and spoken English, as well as a driver's license, is mandatory. Knowledge of German and other Swiss national languages is considered an asset. Strong writing skills and the ability to work in an interdisciplinary environment are expected.

Workplace

Your work will take place in a stimulating environment that promotes collaboration and innovation at one of the leading research institutes globally.

We Offer

• An inspiring, international, and interdisciplinary work environment in a world-leading research institute.
• Opportunities to collaborate with practitioners and federal/cantonal offices.
• Chances to present research at national and international conferences.
• A supportive environment for developing your scientific career.
• Participation in and shaping a dynamic research team with supportive colleagues, fostering collaboration and mutual learning.
• Access to state-of-the-art research infrastructure.

Your job will have a significant impact: Become part of ETH Zurich, which not only supports your professional development but also actively contributes to positive societal change. Expect numerous benefits, such as public transport season tickets, car sharing, a wide range of sports offered by the ASVZ, childcare, and attractive pension benefits.
