Model Based Sediment Quality Management On River Basin Scale, Bernhard Westrich

International Congress on Environmental Modelling and Software

Contaminated sediment mobility plays an important role in river engineering and water resources management. Numerical models are powerful tools to be used for analysis, prediction and remediation issues in sediment management. Erosion stability plays a key role for contaminated sediment mobility assessment. Experimental investigations on erosion stability of undisturbed sediments reveal a large spatial variability of sediment properties. A 1-d and a 2-d numerical transport model is applied to analyse erosion and sedimentation processes of contaminated sediments in the Upper River Rhine reservoirs and in the river Elbe focussing on the effect of the near bank low flowing water zones.

Qualitative Modelling Of Limiting Factors For A Salmon Life Cycle In The Context Of Sustainable River Rehabilitation, R. A. A. Noble, B. Bredeweg, P. Salles, I. G. Cowx

International Congress on Environmental Modelling and Software

This paper describes aspects of a Qualitative Reasoning (QR) model which was developed as part of the EU funded NaturNet-Redime (NNR) project (Sixth Framework Program, Project no. 004074 http://www.naturnet.org ). This project contributed to the European Union’s Strategy for Sustainable Development [European Commission 2001] in the context that the NNR project revolved around developing new technologies (of which QR is one example) for use within a general educational setting, for exploration of sustainable development issues. One of the goals of the NNR project was to improve the Garp3 QR software tool and to construct guidelines for a standardised approach to …

Ecosystem Stability In Integrated Catchment Management, Peter A. Khaiter, Marina G. Erechtchoukova

International Congress on Environmental Modelling and Software

Freshwater is vital for human civilization. Growing population and societal development demand for more water resources. Freshwater is not considered globally scarce, but its distribution across the planet is not even and many countries suffer from water shortage. Human activities constantly produce an impact upon natural waters causing their destruction, degradation and pollution. Freshwater is a multi-purpose resource and this circumstance dictates a need to coordinate the interests of various water users. Integrated catchment management is a framework with the explicit objective to improve natural resources management on a catchment basis. Water resources are an integral part of ecosystems and …

Aqquastudy – Enabling Remote Access To Model-Based Software Tools For Supporting The Design And Operation Of Wwtps, I. Irizar, M. De Gracia

International Congress on Environmental Modelling and Software

Making use of mathematical programming algorithms, a software library (AqLib) has been built for automatically optimising the design and operation of wastewater treatment plants. Currently, AqLib implements seven configurations for nitrogen removal (DN, DN2, RDN, SDN, DRDN, RSDN and DRSDN), five configurations for phosphorous removal (A2O, Bardenpho, Johannesburg, UCT and MUCT), and the anaerobic digestion process. Moreover, an Internet-based service (AqquaStudy) has been deployed so that AqLib can be remotely accessed from any standard web-browser.

The Benchmark Simulation Models – A Valuable Collection Of Modelling Tools, John B. Copp, Ulf Jeppsson, Peter A. Vanrolleghem

International Congress on Environmental Modelling and Software

Over a decade ago, the concept of a tool that could be used to objectivelyevaluate the performance of control strategies through simulation using a standard modelimplementation was introduced for activated sludge wastewater treatment plants. Thatconcept resulted in the development of the Benchmark Simulation Model No 1 (BSM1),the subsequent BSM1_LT and most recently BSM2. Debate about the need and applicationof these models has dogged the development effort since it first began with practitionerssuggesting that these models are only academically applicable, have been conceived of forpublication generation purposes and provide limited benefit to the applied modellingcommunity. The authors of this paper, as …

Cost Effectiveness Analysis For Renewable Energy Sources Integration In The Island Of Lemnos, Greece, A. Angelis-Dimakis, P. Trogadas, G. Arampatzis, D. Assimacopoulos

International Congress on Environmental Modelling and Software

The development of more efficient and least cost energy management interventions is of great importance for isolated energy systems. Islands are typical examples of isolated regions, often highly dependent on imported fossil fuels but with a significant and often unexploited Renewable Energy (RE) potential. This paper presents a least cost planning approach towards the integration of Renewable Energy Sources (RES) in such systems, which is applied to the island of Lemnos, Greece. The approach involves the application of Cost-Effectiveness Analysis (CEA) and Incremental Cost Analysis (ICA) for screening possible alternatives and determining the most economically efficient and effective plan for …

Developing Bayesian Network Models Within A Risk Assessment Framework, C. A. Pollino, Barry T. Hart

International Congress on Environmental Modelling and Software

The risk assessment framework is increasingly being applied to examine both human and non-human stressors on ecological systems. Risk-based decision-making aims to quantify the likelihood of a threat occurring, the consequences of this to an ecological system, process or value, and the associated uncertainty in the predictions. Until recently, the ability to predict changes in dynamic ecosystems due to stressors was limited by both the poor understanding of the drivers of ecological processes and structure, and the lack of modelling tools that could represent such complexity with associated uncertainties. However, the recent growth in the use of Bayesian network tools …

Bayesian Challenges In Integrated Catchment Modelling, Vikas Kumar, A. Holzkämper, B. Surridge, P. I. Rockett, M. Niranjan, D. N. Lerner

International Congress on Environmental Modelling and Software

Bayesian Networks (BNs) are increasingly being used as decision support tools to aid the management of the complex and uncertain domains of natural systems. They are particularly useful for addressing problems of natural resource management by complex data analysis and incorporation of expert knowledge. BNs are useful for clearly articulating both the assumptions and evidence behind the understanding of a problem, and approaches for managing a problem. For example they can effectively articulate the cause-effect relationships between human interventions and ecosystem functioning, which is a major difficulty faced by planners and environment managers. The flexible architecture and graphical representation make …

Trajectories’ Mining Between Subprocesses In A Wastewater Treatment Plant, Karina Gibert, G. Rodriguez Silva, Ignasi Rodríguez Roda

International Congress on Environmental Modelling and Software

In this work the Trajectories’ Mining between subprocesses is presented in regards to the dynamics of a Wastewater Treatment Plant (WWTP). This kind of Environmental Systems involves a high complexity inherent to its own characteristics. Intelligent Environmental Decision Support Systems (IEDSS) can improve the decision making process, assisting decision makers in the evaluation of alternatives and improving management and control of Environmental Systems in general and for this particular application of WWTP. Our line of work is based on the development of methodologies of Artificial Intelligence and Statistics to solve problems of Knowledge Discovery of Data as is shown by …

Assessment And Management Of Environmental Risks Resulting From Operation Of Large-Scale Irrigation Delivery Systems: A Case Study In Southern Italy, D. Zaccaria, M. Scimone

International Congress on Environmental Modelling and Software

The cumulative effects of irrigation delivery schedule on aquifer and onagricultural soils were analysed in a study conducted on a large-scale irrigated area locatedin southern Italy. These effects likely result from the inadequate operation of the largescaleirrigation delivery system. Agriculture in the study area is market-oriented and tightlydependant on irrigation, due to hot and dry climatic conditions and to the poor distributionof seasonal rainfall. The study area is characterized by fairly high levels of groundwatersalinity likely due to intensive exploitation of the aquifer by farmers especially during peakirrigation demand periods. The concentration of groundwater pumping during these periodsresults most likely …

Towards A Simulation-Based Study Of Grassland And Animal Diversity Management In Livestock Farming Systems, G. Martin, Michel Duru, Roger Martin-Clouaire, Jp Rellier, Jp Theau, O. Thérond, L. Hossard

International Congress on Environmental Modelling and Software

In less-favored areas, livestock production involves the management of native vegetation as a resource base. A challenging issue in such systems regards the design of efficient and sustainable management strategies that make it possible to exploit the diversity of grasslands and herd batches over different time scales. This paper describes the conceptual approach that supports the representation and simulation of farm-scale models of grassland-based livestock systems in the SEDIVER project. It enables the coupling of species-rich grasslands and livestock models with sophisticated decision-making models. The latter embed a representation of management strategies that specify in a flexible and adaptive manner …

Intelligent Environmental Decision Support System For Integrated Operation Of Membrane Bioreactors, Ignasi Rodríguez-Roda, Joaquim Comas, Hèctor Monclús, J. Sipma, Manel Poch

International Congress on Environmental Modelling and Software

The target of this paper is to present a prototype of Intelligent Environmental Decision Support System (IEDSS) that guarantees robust and independent monitoring and real-time control of membrane bioreactors, and at the same time allows remote supervision of the integrated operation of the biological process and the physical separation by the membranes. The rule-based and model-based systems include empirical and tacit knowledge to relate parameters of biological control to the membrane unit operation. At the same time, the IEDSS is meant to be equipped with an automatic learning module of the membranes life cycle that records and analyses accumulated experiences …

Addressing Cultural And Institutional Barriers To Data And Model Interoperability, P. Dibner, David Arctur

International Congress on Environmental Modelling and Software

Despite recent technological advances, proliferation of online databases and community data collection and modeling efforts, the environmental observatory and modeling communities remain fragmented due to the lack of summaries of available observations data, differences in information models and metadata, lack of common data discovery and access protocols tuned to model requirements, and significant semantic differences in data description. However, purely technical solutions for interoperability are insufficient for establishing a shared interoperable infrastructure. The establishment of any technology in a population of potential adopters takes place within a context of social and economic processes. A community cannot become instantaneously aware of …

Grassland Songbird Survival And Recruitment In Agricultural Landscapes: Implications For Source-Sink Demography, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

Population growth and decline are particularly sensitive to changes in three key life-history parameters: annual productivity, juvenile survival, and adult survival. However, for many species these parameters remain unknown. For example, although grassland songbirds are imperiled throughout North America, for this guild, only a small number of studies have assessed these parameters. From 2002 to 2006, in the agricultural landscape of the Champlain Valley of Vermont and New York, USA, we studied Savannah Sparrow (Passerculus sandwichensis) and Bobolink (Dolichonyx oryzivorus) demography on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- …
