- KonferenzbeitragA Cellular Automata Model for Flow-like Landslides with Numerical Simulations of Subaerial and Subaqueous Cases(Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Avolio, Maria Vittoria; Lupiano, Valeria; Mazzanti, Paolo; Di Gregorio, SalvatoreNumerical modelling is a major challenge in the prevention of risks related to the occurrence of subaerial and subaqueous landslides. SCIDDICA-SS2 and SCIDDICA-SS2blocks are Macroscopic Cellular Automata models, developed for the simulations of combined subaerial-subaqueous flow-like landslides. SCIDDICA-SS2 was firstly validated on the 1997 subaerial subaqueous debris flow at Lake Albano (Rome, Italy). This paper outlines the last version of the model, slightly improved and which was extended in order to simulate landslide characterized by large blocks inside the main landslide debris. The paper presents applications of the model to a completely submarine landslide, occurred between November 2007 and September 2008, in the nearshore of Bagnara Calabra town (Italy) and to the catastrophic M. Pacì rock-avalanche occurred on February 6, 1783 (Scilla, Italy). Simulation results of Bagnara Calabra submarine landslide by SCIDDICA-SS2 show a strong convergence between the real and simulated areas affected by the event. Furthermore, numerical analyses by SCIDDICA-SS2blocks demonstrate the ability of the model to simulate rock avalanches characterized by large blocks.
- KonferenzbeitragA Common Reference Model for Environmental Science Research Infrastructures(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Chen, Yin; Martin, Paul; Magagna, Barbara; Schentz, Herbert; Zhao, Zhiming; Hardisty, Alex; Preece, Alun; Atkinson, Malcolm; Huber, Robert; Legré, YannickIndependent development of research infrastructures leads to unnecessary replication of technologies and solutions whilst the lack of standard definitions makes it difficult to relate experiences in one infrastructure with those of ot hers. The ENVRI Reference Model, www.envri.eu/rm, uses the Open Distributed Processing standard framework in order to model the "archetypical" environmental research infrastructure. The use of the ENVRI -RM to illustrate common characteristics of European ESFRI environmental infrastructures from a number of different perspectives provides a common language for and understanding of environmental research infrastructures, promote technology and solution sharing between infrastructures, and improve interoperability between implemented services .
- KonferenzbeitragA component based approach for overall Environmental Management Information Systems (EMIS) integration and implementation(Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Giesen, Nils; Hashemi Farzad, Tabassom; Marx Gómez, JorgeThe integration of Environmental Management Information Systems (EMIS) into the existing business information systems of an enterprise is still a complex and expensive assignment. By creating a intelligent software system, the integration and implementation of EMIS in existing systems can be simplified. By following a new procedure model and using a framework, individual solutions in integration and implementation of an environmental information management system in the enterprise wide software landscape can be realized, followed by a self-critical survey, allowing a assessment of the effectiveness of the chosen approach for the individual needs.
- KonferenzbeitragA Data Warehousing and Data Mining Tool for Environmental Accounting(Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Yu, Ting; Lenzen, Manfred; Dey, Chris; Badcock, JeremyThis paper presents an integrated intelligent system being capable of automatically estimating and updating largesize input-output tables for the environmental accounting. This system is a comprehensive solution covering from the data collection and integration, querying, analyzing and presentation. The environmental accounting addresses how to correctly measure the greenhouse gas emission of an organization. Among the various environmental accounting methods, the Economic Input-Output Life Cycle Assessment (EIO-LCA) method uses information about industry transactions-purchases of materials by one industry from other industries, and the information about direct environmental emissions of industries, to estimate the total emissions throughout the whole supply chain. The core engine of the EIO-LCA is the input-output table. This intelligent system is able to interpret and follow users’ XML-based query scripts, retrieve data from various sources and integrate for the following data mining components. The data mining component bases on a unique mining algorithm which estimates the input-output tables from the historical data and the spatial data simultaneously. This mining algorithm runs over the parallel computer to enable the system to estimate a matrix of the size up to 3000-by-3000.
- KonferenzbeitragA Plugin-Based Framework for Domain Models and Persistence in Environmental Management Information Systems(Environmental Informatics and Industrial Ecology, 2008) Busse, Thorsten; Denz, Nicolas; Page, BerndIn this paper, we present an open source framework that supports the implementation of persistable domain models in dynamic plugin-based architectures on Microsoft .NET. The framework includes a domain model service that allows plugins to provide new domain types to other plugins as well as to use, extend, and observe domain objects contributed by other plugins. Furthermore, a persistence service is provided as an abstraction from concrete repository implementations. The paper discusses our solutions to the challenges of persistence in dynamic architectures, presents an exemplary domain-specific language for material flow analysis, and compares our work to related approaches from the common software platforms .NET and Eclipse. Though the framework is in principle application- independent, we apply it primarily in the context of environmental management information systems.
- KonferenzbeitragA pre-market service to map biomass potentials on a regional level(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Tum, Markus; Günther, KurtIn the framework of the EU FP7 project ENDORSE (Energy Downstream Services Providing energy components for GMES) a pre-market service is developed to estimate the annual above ground biomass increase for forests in Germany. This development is driven by the requirements of a prime user (Forest Competence Center Eberswalde) and done in close cooperation with experts in the field of forestry. One aim of the service is to develop a cost and time efficient method to deliver yearly estimates of above ground forest biomass increase using satellite measurements and modelling techniques as the BETHY/DLR SVAT model. Another aim is to use mainly satellite observations coming from GMES services and/or GMES space components. Our yearly estimates of above ground forest biomass increase covering the time span from 2000 to 2012 will fill the gaps of the national forest inventories. In Germany the first and second National Forest Inventory (NFI) took place in the years 1987 and 2002 while the third inventory was performed in 2011 and 2012. This large-scale ground mapping of the forest status and forest productivity uses random sampling of forest parameters for the entire territory of the Federal Republic of Germany. The new pre-market service allows monitoring forest growth on a regional level with 1km x 1km spatial resolution with respect to local meteorological conditions
- KonferenzbeitragA quantitative study on transport time for sustainable road freight logistics(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Froese, JanReferring to the Institute for Energy and Environmental Research (IFEU), road freight transport will increase by 80% between 2004 and 2025. In order to reduce the negative environmental effects freight transport needs to be arranged more sustainably in future. Although rail and water transport is less climate-damaging than road freight, companies hesitate to relocate road freight transport to more environmentally friendly modes because these are slower. But at the moment it is not proven to what extent the majority of customers actually require the fastest possible delivery for their orders. In case longer transport times are accepted in the market, rail and water logistics would be an attractive and sustainable alternative. In this contribution more than 5000 freight transport orders handled in continental Europe have been analyzed in terms of time constraints given by the customers. It can be concluded that there is a significant amount of road transport which could be handled in a slower and more sustainable way. To do so, it is crucial that future transport management systems are able to identify non time-critical orders and support a modal shift.
- KonferenzbeitragA Tool for Modeling and Optimization of Residential Electricity Consumption(Environmental Informatics and Industrial Ecology, 2008) Eysholdt, Moritz; Denecke, Ulrich; Belasus, Michael; Bley, Christian; Eilers, Mark; Erlmann, Michael; Hinrichs, Christian; Hurrelmann, Malte; Bremer, Jörg; Rapp, Barbara; Sonnenschein, Michael; Vogel, UteToday's households face a huge variety of electricity consuming devices on the one hand, and increasing electricity prices and increased awareness for environmental sustainability on the other hand. Fluctuating electricity tariffs currently evaluated by electricity suppliers have the potential to make it even more complex for the electricity consumer to keep costs low. We want to help the consumer to manage this complexity and increase her or his awareness for the electricity consumption of the household's devices. Therefore, we have developed a tool which allows modelling and simulating the set of electricity consuming devices, their loads, and electricity tariffs. It is possible to create schedules for the usage of devices, calculate the resulting load curve and automatically optimize the schedule based on fluctuating power tariffs while paying attention to customer definable constraints. Furthermore, the tool allows comparing modeled and metered load curves, which is especially useful to evaluate correctness and completeness of the household's model. To decrease the modeling effort, the tool can access libraries of predefined devices and tariffs via the Internet.
- KonferenzbeitragA web-GIS tool for industrial symbiosis − Preliminary results and perspectives(Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Massard, Guillaume; Erkman, SurenCycling the use of material in product manufacturing is the conceptual framework of industrial ecology. Within this context, industrial symbiosis creates physical exchanges of materials, energy, water, and/or by-products among economic activities that are collocated or spread through a state or region. Detecting and assessing potential industrial symbiosis and promoting eco-industrial development on a multifunctional territory call for decision support methodologies and tools. Information on material flows needs to be stored in a way that allows data treatment to detect potential exchanges of residues and service mutualization and to assess their feasibility. A database was created to store data on economic activities, manufacturing processes and related material and energy flows. A clearly defined terminology allows application of algorithms for treatment and retrieval of information. In addition, a geographic information system interface (web-GIS) was developed as technical and decision support tool for engineers and territorial planners. It allows, among other things, the detection and the visualization of potential exchanges, the assessment of technical and geographical feasibility, the detection of new potential partners within the manufacturing activities and the identification of optimal location for new facilities based on material flows consideration. Interactions with other spatial layers extend the detection to other economic activities such as agriculture, housing or services. The methodology and the tool developed aim at providing useful information for a more efficient and local use of resources. They may be a valuable instrument in the hands of public and private institutions seeking information on manufactures and their organization. This paper aims at establishing how a web-GIS tool for industrial symbiosis may support decision making in industrial and territorial planning. This paper focuses on the experience initiated by the state and republic of Geneva (Switzerland). Since 2004, the state’s Agenda 21 supports a project aiming at detecting and implementing industrial symbiosis on its territory.
- KonferenzbeitragA Webbased application for crowdsourced acquisition of species data in the UNESCO MaB Biosphere Reserve Bliesgau(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Gülden, Christian; Mattern, Michael; Fischer-Stabel, PeterThe world network of nature reserves has remarkable high natural values (high ecological integrity, high biodiversity, limited human use, rather unstressed systems, resource management is not extractionoriented, etc.) and high cultural values. Especially the UNESCO biosphere reserves comprise ecosystems and people, thus reflecting the human dimension in the environment. It is a network founded upon principles of maintaining biological values while sustaining human populations. In addition, Biosphere reserves serve as laboratories for research and demonstration of ways in progressing towards sustainability of human-environment interactions (including wise-use and economic development). In addition, Biosphere reserves are part of an UNESCO interdisciplinary research program that examines the environmental, social and economic dimensions of biodiversity loss in order to conserve biological and cultural diversity. This is being achieved by providing models of land management and sites of excellence for sustainable development research, environmental monitoring, education and training. To achieve this for the biosphere reserve Bliesgau, it is necessary that a dialogue between environmentalists and the general public will take place to raise awareness of this particular region. The goal is to accomplish this with the help of a web based application that concentrates on featured species, makes them known and encourages the public to take an active part in the preservation. The users can look up detailed information about these species or even interactively assist by seeking these and register them in a map inside the application and provide important information on their finding and the locality. In this way, not only the distribution of the species is mapped, in addition, the people are incorporated into the project Biosphere Bliesgau.
