701-1240-00L | Modelling Environmental Pollutants Number of participants limited to 50. | O | 3 KP | 2G | M. Scheringer, C. Bogdal | |

Kurzbeschreibung | Modeling the emissions, transport, partitioning and transformation/degradation of chemical contaminants in air, water and soil. | |||||

Lernziel | This course is intended for students who are interested in the environmental fate and transport of volatile and semi-volatile organic chemicals and exposure to pollutants in environmental media including air, water, soil and biota. The course focuses on the theory and application of mass-balance models of environmental pollutants. These models are quantitative tools for describing, understanding, and predicting the way pollutants interact with the environment. Important topics include thermodynamic and kinetic descriptions of chemical behavior in environmental systems; mechanisms of chemical degradation in air and other media; novel approaches to modeling chemical fate in a variety of environments, including lakes and rivers, generic regions, and at the global scale, and application of mass balance modeling principles to describe bioaccumulation of pollutants by fish and mammals. | |||||

Inhalt | Application of mass balance principles to chemicals in a system of coupled environmental media. Measurement and estimation of physico-chemical properties that determine the environmental behavior of chemicals. Thermodynamic and kinetic controls on the behavior of pollutants. Modeling environmental persistence, bioaccumulation and long-range transport potential of chemicals, including a review of available empirical data on various degradation processes. Current issues in multimedia contaminant fate modeling and a case study of the student's choice. | |||||

102-0617-01L | Methodologies for Image Processing of Remote Sensing Data | O | 3 KP | 2G | I. Hajnsek, O. Frey, S. Li | |

Kurzbeschreibung | The aim of this course is to get an overview of several methodologies/algorithms for analysis of different sensor specific information products. It is focused at students that like to deepen their knowledge and understanding of remote sensing for environmental applications. | |||||

Lernziel | The course is divided into two main parts, starting with a brief introduction to remote sensing imaging (4 lectures), and is followed by an introduction to different methodologies (8 lectures) for the quantitative estimation of bio-/geo-physical parameters. The main idea is to deepen the knowledge in remote sensing tools in order to be able to understand the information products, with respect to quality and accuracy. | |||||

Inhalt | Each lecture will be composed of two parts: Theory: During the first hour, we go trough the main concepts needed to understand the specific algorithm. Practice: During the second hour, the student will test/develop the actual algorithm over some real datasets using Matlab. The student will not be asked to write all the code from scratch (especially during the first lectures), but we will provide some script with missing parts or pseudo-code. However, in the later lectures the student is supposed to build up some working libraries. | |||||

Skript | Handouts for each topic will be provided. | |||||

102-0488-00L | Water Resources Management | O | 3 KP | 2G | A. Castelletti | |

Kurzbeschreibung | Modern engineering approach to problems of sustainable water resources, planning and management of water allocation requires the understanding of modelling techniques that allow to account for comprehensive water uses (thereby including ecological needs) and stakeholders needs, long-term analysis and optimization. The course presents the most relevant approaches to address these problems. | |||||

Lernziel | The course provides the essential knowledge and tools of water resources planning and management. Core of the course are the concepts of data analysis, simulation, optimization and reliability assessment in relation to water projects and sustainable water resources management. | |||||

Inhalt | The course is organized in four parts. Part 1 is a general introduction to the purposes and aims of sustainable water resources management, problem understanding and tools identification. Part 2 recalls Time Series Analysis and Linear Stochastic Models. An introduction to Nonlinear Time Series Analysis and related techniques will then be made in order to broaden the vision of how determinism and stochasticity might sign hydrological and geophysical variables. Part 3 deals with the optimal allocation of water resources and introduces to several tools traditionally used in WRM, such as linear and dynamic programming. Special attention will be devoted to optimization (deterministic and stochastic) and compared to simulation techniques as design methods for allocation of water resources in complex and competitive systems, with focus on sustainability and stakeholders needs. Part 4 will introduce to basic indexes used in economical and reliability analyses, and will focus on multicriteria analysis methods as a tool to assess the reliability of water systems in relation to design alternatives. | |||||

Skript | A copy of the lecture handouts will be available on the webpage of the course. Complementary documentation in the form of scientific and technical articles, as well as excerpts from books will be also made available. | |||||

Literatur | A number of book chapters and paper articles will be listed and suggested to read. They will also be part of discussion during the oral examination. | |||||

Voraussetzungen / Besonderes | Suggested relevant courses: Hydrologie I (or a similar content course) and Wasserhaushalt (Teil "Wasserwirtschaft", 4. Sem. UmweltIng., or a similar content course) for those students not belonging to Environmental Engineering. |
