Environmental Damage Assessment Applied To Process Analysis. A Decision Support Alternative, I. Herrera, L. Kulay, Laureano Jiménez, Marta Schuhmacher Jul 2002

Environmental Damage Assessment Applied To Process Analysis. A Decision Support Alternative, I. Herrera, L. Kulay, Laureano Jiménez, Marta Schuhmacher

International Congress on Environmental Modelling and Software

Nowadays the environmental studies are increasingly important in the process analysis and design. These studies not only can be used to quantify the environmental damage, but also, as optimisation criteria together with technical and economical evaluations. In the present study, we develop a methodology based on several techniques (Risk Assessment (RA), Design Support Framework (DSF), and Endpoints Indicators Applying). This methodology which links the main aspects of process analysis and environmental damage assessment, comprehends three main steps: the first one involves the accomplishment of an inventory of raw material and energetic streams, which may be predicted or computed depending on …

Parallel Processing For A Better Understanding Of Equifinality In Hydrological Models, A. Hreiche, D. Mezher, C. Bocquillona, A. Dezetter, E. Servat, W. Najem Jul 2002

Parallel Processing For A Better Understanding Of Equifinality In Hydrological Models, A. Hreiche, D. Mezher, C. Bocquillona, A. Dezetter, E. Servat, W. Najem

International Congress on Environmental Modelling and Software

The aim of conceptual modeling of watersheds is to realize a numeric scheme for determining rainfallrunoff at the outlet of a basin. This modeling consists of a number of parameters that are identified by calibration methods using a series of measured rainfall-runoff data. One of the difficulties of this method is due to equifinality problems. The definition of the parameters, and their relation with the data, extends the space of acceptable parameters (zone of equivalence), which in turn makes the combination of acceptable parameters very large. In addition, the calibration methods currently used simplify the parameter hyper-space and yield equally …

An Application Of Queuing Theory To Waterfowl Migration, Richard S. Sojda, John E. Cornely, Leigh H. Fredrickson Jul 2002

An Application Of Queuing Theory To Waterfowl Migration, Richard S. Sojda, John E. Cornely, Leigh H. Fredrickson

International Congress on Environmental Modelling and Software

There has always been great interest in the migration of waterfowl and other birds. We have applied queuing theory to modelling waterfowl migration, beginning with a prototype system for the Rocky Mountain Population of trumpeter swans (Cygnus buccinator) in Western North America. The queuing model can be classified as a D/BB/28 system, and we describe the input sources, service mechanism, and network configuration of queues and servers. The intrinsic nature of queuing theory is to represent the spatial and temporal characteristics of entities and how they move, are placed in queues, and are serviced. The service mechanism in our system …

Comparing Basal Area Growth Models, Consistency Of Parameters, And Accuracy Of Prediction, J. J. Colbert, Michael Schuckers, Desta Fekedulegn

International Congress on Environmental Modelling and Software

We fit alternative sigmoid growth models to sample tree basal area historical data derived fromincrement cores and disks taken at breast height. We examine and compare the estimated parameters forthese models across a range of sample sites. Models are rated on consistency of parameters and on theirability to fit growth data from four sites that are located across a longitudinal gradient across the states ofDelaware, Pennsylvania, West Virginia, and Ohio in the USA. We then examine the differences among thesemodels in their abilities to predict short-term (decade) and longer-term growth of trees. Accuracy andpotential effects of bias are discussed relative …

Integrated Modelling And Decision Support Tools: A Mediterranean Example, T. Oxley, N. Winder, Brian Mcintosh, M. Mulligan, Guy Engelen

International Congress on Environmental Modelling and Software

A great deal of new knowledge and research material has been generated from research carried out under the auspices of the EU. However, only a small amount has been made available as practical policysupport tools. In this paper we describe how EU funded research models and understanding has been integrated into an interactive Decision Support System addressing physical, economic and social aspects of land degradation in the Mediterranean. We summarise the 10 constituent models that simulate hydrology, human influences, crops, natural vegetation and climatic conditions. The models operate on very different spatial and temporal scales and utilise different modelling techniques …

Implementing A Process-Based Decision Support Tool For Natural Resource Management - The Geowepp Example, C. S. Renschler, D.C. Flanagan Jul 2002

Implementing A Process-Based Decision Support Tool For Natural Resource Management - The Geowepp Example, C. S. Renschler, D.C. Flanagan

International Congress on Environmental Modelling and Software

Practical decision-making in spatially distributed natural resource management is increasingly based on process models linked to Geographical Information Systems (GIS). Geo-spatial environmental data and decision support tools can now be made available to a much larger audience by using powerful personal computers and internet-accessible mapping tools. Traditionally decision support tools based on process models were not typically developed for applications across a wide range of spatial and temporal scales of interest, utilizing commonly available data of variable precision and accuracy, and Graphical User Interfaces (GUIs) to communicate with a diverse spectrum of users with different levels of expertise. To implement …

Agent Based Simulation In Integrated Assessment And Resources Management, Claudia Pahl-Wostl Jul 2002

Agent Based Simulation In Integrated Assessment And Resources Management, Claudia Pahl-Wostl

International Congress on Environmental Modelling and Software

Resource management problems have become more and more complex. The traditional approach to solving isolated environmental problems with technological fixes and end-of-pipe solutions has started to shift towards a more thoughtful and integrated attitude. Hence it becomes more and more important to develop appropriate means for representing the human dimension in integrated models and in the development of resource management regimes. This involves the development of integrated approaches to problem solving and thus to include as well stakeholder perspectives. Stakeholder should be included in the process of developing and adopting any resource management plan. In order to improve stakeholder-based policy …

Participatory Decision Making In Reservoir Planning, R. Soncini-Sessa, A. Castelletti, E. Weber Jul 2002

Participatory Decision Making In Reservoir Planning, R. Soncini-Sessa, A. Castelletti, E. Weber

International Congress on Environmental Modelling and Software

The technologies and methods for integrated planning and management of water resource systemshave matured considerably over the past decades. However, relatively few of them have been actually and regularlyapplied in real world decisional processes. We feel this is essentially due to a general lack of engagementof stakeholders and decision makers at every stage of the decisional process. Innovative methodologies andtools to improve participation are presented, with focus on water reservoir systems

The Control Of Algal Bloom Damages To Clam Yield In A North Adriatic Coastal Lagoon (Sacca Di Goro, Italy), F. Cellina, G. A. De Leo, M. Bartoli, P. Viaroli Jul 2002

The Control Of Algal Bloom Damages To Clam Yield In A North Adriatic Coastal Lagoon (Sacca Di Goro, Italy), F. Cellina, G. A. De Leo, M. Bartoli, P. Viaroli

International Congress on Environmental Modelling and Software

During the last twenty years the economic activity of clams exploitation has been intensively developed in the southernmost coastal lagoon of the Italian Po river delta, Sacca di Goro. Still, clam breeding is in danger because of frequent summer algal blooms, due to Ulva rigida macroalgae. These blooms cause anoxic crises leading clams to collapse, with a consequent deep impact on the whole economic sector of clams exploitation. Several strategies have been developed to avoid the loss of commercial production, yet none of them has been assessed on a mathematical basis. In this work we develop a simple stochastic mathematical …

An Agent-Group-Role Based Modelling Framework For Participative Water Management Support, Geraldine Abrami, Olivier Barreteau, Flavie Cernesson Jul 2002

An Agent-Group-Role Based Modelling Framework For Participative Water Management Support, Geraldine Abrami, Olivier Barreteau, Flavie Cernesson

International Congress on Environmental Modelling and Software

Agent-based modelling can be used as a tool for participative water management support. Within this framework, we want to develop architectural features that can improve system understanding at the collective and individual levels. We present a modelling framework which aims at bringing particular insights into the interrelations between temporal, spatial and social scales of the resource management process. To study these links, we adopt an approach based on the notions of role, group and agent: roles represent the functions of agents as members of a group; a group consists of a set of agents that interact in a process through …

The Economic Consequences Of Voluntary Environmental Information Disclosure, Nike O. Gozali, Janice C. Y. How, Peter Verhoeven

International Congress on Environmental Modelling and Software

A significant body of accounting and finance literature has witnessed an increase in the demandfor company’s environmental information over the past few decades. Using data of Australian companiesfrom 1998 to 2000, this study provides an analysis of environmental disclosure in companies’ annual reports.The evidence indicates that companies do respond to the increased demand for environmental disclosure byproviding more environmental-related information in their annual report. Although the requirement todisclose environmental information in annual reports has not kept pace with the legislative reform, there hasbeen a significant increase of these disclosures from 1998 to 2000. We also find that most of the …

How Bad Isn't The Agent-Based Model Catchscape?, N. Becu, P. Perez, Olivier Barreteau, A. Walker

International Congress on Environmental Modelling and Software

Due to mounting human pressure, stakeholders in northern Thailand are facing crucial natural resource management issues. The impact of upstream irrigation management on the downstream agricultural viability is a common source of conflict. It has often both biophysical and social origins. CATCHSCAPE has been developed as an Agent-Based model that enables us to describe the whole catchment: hydrology, farmers’ behaviour and water management rules. It is meant to simulate scenarios based on assumptions about value of these features as well as some assumptions about context, such as levels of prices for various commodities or climate. The biophysical modules are made …

Probabilistic Ecological Risk Assessment Framework For Chemical Substances, F. A. M. Verdonck, J. Jaworska, C. R. Janssen, Peter A. Vanrolleghem Jul 2002

Probabilistic Ecological Risk Assessment Framework For Chemical Substances, F. A. M. Verdonck, J. Jaworska, C. R. Janssen, Peter A. Vanrolleghem

International Congress on Environmental Modelling and Software

The goal of probabilistic ecological risk assessment (PERA) is to estimate the likelihood and the extent of adverse effects occurring to ecological systems due to exposure(s) to substances. It is based on the comparison of an exposure concentration distribution (ECD) with a species sensitivity distribution (SSD) derived from chronic toxicity data. A PERA framework was proposed and illustrated with a case study on the pesticide atrazine in the surface waters of Flanders. The risk and its uncertainty or confidence interval can be visualised in a pie chart. A probabilistic approach results in a more realistic environmental risk assessment and therefore …

Outlook-Based Concept For The Population And Updating Of A Meta-Information System In Environmental Administration, P. Fischer-Stabel, R. Krieger, E. Rietzke Jul 2002

Outlook-Based Concept For The Population And Updating Of A Meta-Information System In Environmental Administration, P. Fischer-Stabel, R. Krieger, E. Rietzke

International Congress on Environmental Modelling and Software

Metadata is essential in retrieving information about the environment located at differentlydistributed organisational units of governmental administration. The population of the meta-informationsystem may be done based either on a centralised concept (e.g. with support of external interviewers) or on anon-centralised concept requiring a software tool accessible at each desktop computer where the dataholdercan enter the data directly. Often the implementation of such a tool is linked with a high effort in installationand training, especially if hundreds of clients have to be served. To overcome these disadvantages wedeveloped a software tool based on MS Outlook supporting the non-centralised maintenance concept. Thesoftware …

Integrating Structural Changes In Future Research And Modelling On The Seine River Basin, H. Kieken Jul 2002

Integrating Structural Changes In Future Research And Modelling On The Seine River Basin, H. Kieken

International Congress on Environmental Modelling and Software

For years policy makers and researchers involved in the management of the Seine river basin haveshared a common representation of the system's structure and behaviour: Paris, in the centre, divides thewatershed into two very unequal parts, a "clean" upstream and the downstream where environmentalproblems occur due to Paris sewage. This representation resulted in both (1) a focus of the attention and theefforts of policy makers on the downstream area and (2) the structuring of scientific research on the SeineRiver in a very dissymmetric way, including the features of the models developed within the 12-year old andstill ongoing research programme dedicated …

A Bayesian Network For Investigating The Decline In Fish Catch In Switzerland, M. E. Borsuk, Patricia Burkhardt-Holm, Peter Reichert

International Congress on Environmental Modelling and Software

Catches of brown trout have decreased about 50% in many rivers and streams in Switzerland in the past 15 years. Additionally, the health status of numerous brown trout populations has been assessed to be impaired. In order to evaluate the causes for these phenomena, a nationwide interdisciplinary project named “Fischnetz” was launched in 1999. Twelve hypotheses for the fish population declines were proposed and laboratory and field research projects were initiated to investigate these suggested causes. To apply the results of these investigations to the task of discerning the relative causal importance of each of the hypotheses, a Bayesian probability …

Implementing Soil And Water Conservation Production Systems At The Farm Level, Ted L. Napier, Silvana M. Napier Jul 2002

Implementing Soil And Water Conservation Production Systems At The Farm Level, Ted L. Napier, Silvana M. Napier

International Congress on Environmental Modelling and Software

Factors influencing adoption of soil and water conservation production systems at the farm level arediscussed in the context of their influence for motivating land owner-operators to adopt and to use conservationtechnologies and practices. Research focused on United States (US) farmers are examined to assess how social,economic, farm structure, and conservation program-participation factors affect adoption behaviors at the farmlevel. Research findings suggest that contemporary conservation programs that place emphasis on the provision ofinformation, education, technical assistance, and economic subsidies probably will not be successful in achievingsocietal conservation goals. Study findings basically demonstrated that factors commonly argued to influenceadoption of conservation production …

An Enterprise-Based Grid Resource Management System, Mark J. Clement, Joseph Ekstrom, Quinn O. Snell, Kevin B. Tew

Faculty Publications

As the Internet began its exponential growth into a global information environment, software was often unreliable, slow and had difficulty in interoperating with other systems. Supercomputing node counts also continue to follow high growth trends. Supercomputer and grid resource management software must mature into a reliable computational platform in much the same way that web services matured for the Internet. DOGMA The Next Generation (DOGMA-NG) improves on current resource management approaches by using tested off-the-shelf enterprise technologies to build a robust, scalable, and extensible resource management platform. Distributed web service technologies constitute the core of DOGMA-NG’s design and provide fault …
