AbstractThe field course consist of an introductory part and two days of field work focusing on a lake system. The students will gather insights into sensor technology for quantifying hydrological and chemical processes. They learn how to evaluate data series and to apply simple models in order to address questions of water management.
ObjectiveThe studens get familiar with in-situ measurements and sampling of water and sediments. They use their knowledge in chemistry and systems analysis in order to address questions of ecosystem functions and the management of a lake in an intensively modified environment.
ContentThe introduction (3 hours) covers the basic themes of
* lakes as biogeochemical systems, stratrification of the water column, variability of in- and outflows, sediment archives,
* typical measurement systems for hydrological and chemical parameters,
* working groups for the field days and workplan.

In the field course the students work in groups on three different topics
1. The lake reflects its catchment: The students analyze nutrient loads in the inflows and the outflow and use existing data to construct a mass balance

2. Sediment archives: We retrieve sediment cores in order to estimate sedimenation rates and to reconstruct the changes in water quality over the last century.

3. From light to darkness: Using profiling equippment the students analyze the vertical stratification of the lake and the varibility of light and chemical parameters.

4. Think about it! In the fourth part the students assemble the different facts in order to draw some practical conclusions.
Lecture notesA guide for the field work and electronic data series will be avialable.

AbstractStudents work in teams to develop an interdisciplinary research question on the basis of a current environmental topic. They research the literature necessary to answer it and create an overview of the scientific facts. On this basis, they then produce information material for a non-scientific audience in a selected media form.
ObjectiveStudents are able to
- develop a question on a given interdisciplinary environmental topic by researching the current research literature and documenting it in a literature management program
- summarise the scientific facts relevant to a given question in a collaborative approach
- prepare and communicate scientific facts for a given question in a suitable form for a non-scientific audience

AbstractThe ability to critically evaluate original (scientific) literature and to summarize the information in
a succinct manner is an important skill for any student. This course aims to practice this ability, requiring each student to write a term paper on a topic of relevance for research in the areas of biogeochemistry and pollutant dynamics.
ObjectiveThe goal of the term paper is to train the student's ability to
critically evaluate a well-defined set of research subjects, and to
summarize the findings concisely in a paper of scientific quality. The
paper will be evaluated based on its ability to communicate an
understanding of a topic, and to identify key outstanding questions.
Results from this term paper will be presented to the fellow students and
involved faculty in the following semester (Term paper seminars)
ContentEach student is expected to write a paper with a length of approximately 15 pages. The students can choose from a list of topics prepared by the supervisors, but the final topic will be determined based on a balance of choice and availability. The students will be guided and advised by their advisors throughout the term. The paper itself should contain the following elements: Motivation and context of the given topic (25%), Concise presentation of the state of the science (50%), Identification of open questions and perhaps outline of opportunities for research (25).
In addition, the accurate use of citations, attribution of ideas, and the judicious use of figures, tables, equations and references are critical components of a successful paper. Specialized knowledge is not expected, nor required, neither is new research.
Lecture notesGuidelines and supplementary material will be handed out at the beginning of the class.
LiteratureWill be identified based on the chosen topic.
Prerequisites / NoticeEach term paper will be reviewed by one fellow student and one faculty. The submission of a written review is a condition for obtaining the credit points.
There is no final exam. Grade is assigned based on the quality of the term paper and the submission of another student's review.

AbstractThis seminar focuses on the technical, economic, and political challenges of dealing with water allocation and pollution problems in large international river systems. It examines ways and means through which such challenges are addressed, and when and why international efforts in this respect succeed or fail.
ObjectiveAbility to (1) understand the causes and consequences of water scarcity and water pollution problems in large international river systems; (2) understand ways and means of addressing such water challenges; and (3) analyse when and why international efforts in this respect succeed or fail.
ContentBased on lectures and discussion of scientific papers and reports, students acquire basic knowledge on contentious issues in managing international water resources, on the determinants of cooperation and conflict over international water issues, and on ways and means of mitigating conflict and promoting cooperation. Students will then, in small teams coached by the instructors, carry out research on a case of their choice (i.e. an international river basin where riparian countries are trying to find solutions to water allocation and/or water quality problems associated with a large dam project). They will write a brief paper and present their findings towards the end of the semester.
Lecture notesSlides and reading materials will be distributed electronically.

AbstractStudents write an individual term paper on technical, economic, and political water challenges in an international context. Coached by one of the instructors, students develop and write a case study that examines ways and means to address a specific challenge, and to evaluate success or failure of international collaboration.
ObjectiveIn developing their individual term paper, the students broaden their overview of (1) causes and consequences of water scarcity and water pollution problems in an international context; (2) they assess concepts and policies to mitigate a specific water challenge, and (3) they analyze determinants of success or failure of international collaboration in the water sectors.
ContentIn the basic course on Cooperation and Conflict... 860-0012-00L the students students acquire basic knowledge on contentious issues in managing international water resources, on the determinants of cooperation and conflict over international water issues, and on ways and means of mitigating conflict and promoting cooperation.
In this course, which is reserved to STP students, the participants will be individually coached by one of the instructors and do research and develop a case-study paper on an international water challenge of their choice. The topic should avoid overlap with the work in course 860-0012-00L.
