- KonferenzbeitragA Case Study on an Automated Generation of Environmental Reports(The Information Society and Enlargement of the European Union, 2003) Marx-Gómez, Jorge; Rautenstrauch, Claus; Isenmann, RalfDie unterschiedlichen Dokumente, die im Rahmen einer Umweltberichterstattung von Unternehmen erstellt werden, basieren auf ähnlichen und teilweise überlappenden Informationen. Oft können die für ein bestimmtes Umweltdokument zusammengetragenen Informationen allerdings nicht oder nur mit großem Aufwand für andere Zielsetzungen wieder genutzt werden. Die in den Dokumenten enthaltenen Umweltdaten müssen regelmäßig (z. B. entsprechend dem Berichtszeitraum) aktualisiert werden. Eine rechnergestützte und zumindest teilweise automatisierte Berichterstattung erscheint daher sinnvoll. In diesem Beitrag wird ein Ansatz zur teilweise automatisierten Umweltberichterstattung vorgestellt. Der Schwerpunkt liegt hierbei in der automatischen Überführung von Ökobilanzdaten in eine XML-Form und der Integration in einen Umweltbericht. Dies wird am Beispiel des Softwaretools Umberto illustriert.
- KonferenzbeitragA CORBA-Based Polymorph Software Architecture for Applications Serving the Quality and Environmental Management Systems(The Information Society and Enlargement of the European Union, 2003) Tsanov, NikolayWhile in recent years the Quality and Environmental Management backbone has experienced substantial growth through the introduction of ISO 14001:1996 and ISO 9000:2000 families of standards, little has changed in the information-computing systems serving the Quality Management Systems (QMS) and the Environment Management Systems (EMS). Through the present contribution, author introduces the Acsymiry © 2001 project developed at the Department of Computer Systems and Technologies of the Technical University of Gabrovo, Bulgaria. Acsymiry © stands for ‘Adaptive Computer System for Managing and Controlling the Information Resources Inside Quality Management Systems’.
- KonferenzbeitragA Coupled Model for Transport, Geochemistry and Redox Processes(The Information Society and Enlargement of the European Union, 2003) Horner, Christoph; Holzbecher, Ekkehard; Wiese, Bernd; Nützmann, GunnarA reactive multicomponent chemical transport model to describe redox processes during bank-filtration dealing with equilibrium chemistry and Kinetics of biodegradation is presented. The model approach considers hydrodynamic transport, biodegradation kinetics and equilibrium chemistry speciation. Due to their different mathematical character the transport and reaction model subsets are coupled by a two step procedure (“operation splitting”). The multi species hydrodynamic advection-dispersion subset is a partial differential equation system, the Kinetics subset are ordinary differential equation systems, and the equilibrium subset is a nonlinear algebraic equation system. The model was set up using user friendly software tools as ModelMaker 3 an MATLAB4 which offer powerful tools to solve partial differential and ordinary differential equation systems. The model is demonstrated to three test-cases typical for river bank-filtration and verified by available geochemical software. Topic: Modelling and simulation of environmental systems
- KonferenzbeitragA Generic Procedure for Simultaneous Estimation of Monotone Trends and Seasonal Patterns in Time Series of Environmental Data(The Information Society and Enlargement of the European Union, 2003) Hussian, Mohamed; Grimvall, AndersMost of the currently used methods for time series analysis have been developed for official statistics and economic forecasting. This article is devoted to new non-parametric procedures that take into account some very widespread features of environmental data. In particular, we propose an algorithm for simultaneous estimation of monotone temporal trends and smooth seasonal patterns. Similar algorithms may also be used to combine the extraction of trend and seasonal components with removal of natural fluctuations that can be attributed to meteorological and other physical forcings of the environmental system under consideration.
- KonferenzbeitragA GIS — Based Tool for Detailed Planning Works for Enhancing the Ecomorphological Quality of Running Waters(The Information Society and Enlargement of the European Union, 2003) Fischer, Michael; Barnikel, Günter; Haase, Michael; Westbomke, JörgDie Gewässerentwicklung stellt gegenwärtig und auch in Zukunft insbesondere im Zusammenhang mit der europäischen Wasserrahmenrichtlinie ein zentrales Aufgabenfeld der Wasserwirtschaft dar. Sie umfaßt alle Maßnahmen, die darauf ausgerichtet sind, die wasserwirtschaftliche und ökologische Funktionsfähigkeit, das landschaftliche Erscheinungsbild sowie den Erlebniswert der Gewässer und ihrer Aue zu erhalten oder nachhaltig zu verbessern. Die Umsetzung der naturnahen Gewässerentwicklung erfolgt im Land Baden-Württemberg mittels des Instrumentariums der Gewässerentwicklungsplanung. Diese besteht aus dem Gewässerentwicklungskonzept (einer überörtlichen Rahmenplanung) und dem Gewässerentwicklungsplan (einer detaillierten Planung für den örtlichen Bereich). Der nachfolgende Aufsatz beschreibt ein Instrument zur GIS-gestützten Erstellung von Gewässerentwicklungsplänen.
- KonferenzbeitragA GIS-Based Integrated Simulation Environment for Linking Land Use Patterns to Ecosystem Processes(The Information Society and Enlargement of the European Union, 2003) Schaldach, RüdigerProzesse der Landnutzung und deren Änderung haben einen starken Einfluss auf die biogeochemischen Stoffkreisläufe von Forstund Agrarökosystemen und sind damit eine wichtige treibende Kraft für die Emission und die Festlegung (Senken) von Treibhausgasen. ISE (Integrated Simulation Environment) ist ein Simulationssystem, das ein räumlich explizites Landnutzungsmodell mit Modellen zur Berechnung von Emissionen des Treibhausgases N2O aus der Landwirtschaft und zur Abschätzung des Sequestrierungspotenzials von CO2 im Boden und in oberirdischer Biomasse koppelt. Simulationsstudien werden auf regionaler Ebene für das Bundesland Hessen in einem Zeithorizont bis 2020 durchgeführt. Die technische Umsetzung erfolgt als ein Dienst-orientiertes Konzept auf Basis der GIS Software ArcGIS und dem Component Object Model (COM).
- KonferenzbeitragA Meta-Model for Water Quantity and Water Quality(Integration of Environmental Information in Europe, 2010) Gnauck, Albrecht; Pillmann, WernerThe management of water resources requires simulation models for different time horizons and spatial scales as well as different types of information systems as GIS or Water Information Systems. Mathematical models integrate former experiences and theoretical knowledge about a system with actual information gained by natural processes and man-induced activities. Because of the great variety and complexity of processes considered for water management and their natural or anthropogenic origins different structural dynamic models have to be combined. The questions that must be answered for water management options are how much water is available, for what purposes it will be used, who are the actors and stakeholders, and what kind of consequences follow from distinguished management options for the public, agriculture and industry, and what kind of environmental (or ecological) responses result from anthropogenic activities. For this reason, and to make different subsystems comparable, a Meta-Model is used. In the paper, an overview is given on the methodology how to construct a water quantity and quality meta-model as a tool to manage water systems, and as a base for decision making.
- KonferenzbeitragA Method to Optimise Sampling Strategies — Key Study Goitsche, Bitterfeld, Germany(The Information Society and Enlargement of the European Union, 2003) von Tümpling, Wolf; Horst, Franziska; Schultze, MartinScientific investigations are often combined with sampling campaigns over a large time period at a set of sampling places. To answer the analytical question a problem or investigation oriented and adapted sampling strategy is thereby a fundamental condition for an optimal acquisition of needed information. Without detailed previous knowledge intensive and complex preliminary investigations are necessary. From the results of these investigations an optimised sampling strategy for the following routine investigations can be developed, in order to avoid redundancies and to win the necessary information costand working time optimised. Exemplary of a sampling strategy optimisation the time series analysis will be discussed for water chemical investigation during the flooding of the Mining lake Goitsche near Bitterfeld between 1999 and 2002.

- KonferenzbeitragA Software Tool for Assessing the Effect of Traffic on Wildlife Populations(The Information Society and Enlargement of the European Union, 2003) Finke, Jens; Köster, Frank; Frank, Karin; Sonnenschein, MichaelThe software tool presented in this paper, named AniTraX, was developed in close cooperation of the Oldenburg Research and Development Institute for Tools and Systems in Computing Science (OFFIS) and the Centre for Environmental Research Leipzig-Halle (UFZ). It is intended to support researchers and managers in the field of species conservation and landscape planning, who have limited experience in modelling or programming. AniTraX implements a generic model for the assessment of wildlife mortality, which is caused by anthropogenic impacts such as road traffic. Though the primarily application of AniTraX is the assessment of quantities such as the number of animals killed or the individual mortality, the tool can also be used as a module for assessing effects on higher hierarchical levels, e.g. population size or viability.
