Challenges Encountered During Integrated Modelling Across Multiple Catchments, Neville D. Crossman, Brett A. Bryan Jul 2006

Challenges Encountered During Integrated Modelling Across Multiple Catchments, Neville D. Crossman, Brett A. Bryan

International Congress on Environmental Modelling and Software

There has been a recent trend in natural resource management decision making toward target setting and the use of models to identify geographic priorities to meet those targets. However, measurable and quantitative targets for assessing progress toward achieving management and policy goals tend not to be established. This may be due in large part to a lack of clarity in data and model availability, and geographic prioritisation processes. The long history of extensive human activity and modification of natural resources in the Murray Darling Basin of southern Australia has led to a myriad of natural resource management problems, particularly dryland …


Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown Jul 2006

Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown

International Congress on Environmental Modelling and Software

Uncertainty pervades all aspects of environmental policy making. Numerous typologies and techniques have been developed to conceptualise, classify, assess (qualitatively and quantitatively), propagate, control, reduce and communicate uncertainty. Such assessments are a necessary but insufficient condition for reducing uncertainty in environmental decision making. In this paper we discuss how uncertainty is translated into decisions. Since this entails numerous value judgements and trade-offs which are sensitive to how policy problems are framed, we argue that perceptions of uncertainty cannot be viewed independently of the (quality of) the policy process that it intends to inform. Thus, uncertainty management should not be limited …

Application Of Mesocasimir: Assessment Of Baetis Rhodani Habitat Suitability, A. M. Mouton, M. Schneider, I. Kopecki, Peter L. M. Goethals, N. De Pauw

International Congress on Environmental Modelling and Software

The assessment of the ecological status of running waters at a mesohabitat scale is commonly based on fish. Nevertheless, due to their strong dependence on a good physical and chemical habitat, macroinvertebrate species can also be used for this assessment. A new approach is presented by applying the MesoCASiMiR module of the CASiMiR modeling system. In this way, the habitat suitability for the mayfly Baetis rhodani was modeled at a mesohabitat scale in the river Zwalm (Flanders, Belgium). The model inference system was based on fuzzy logic. Fuzzy variable sets and rules were derived from expert knowledge and from a …

A Protocol For The Development, Evaluation And Application Of Environmental Models In Decision Making, Noha Gaber, Pasky Pascual, Gary Foley, Neil Stiber, Elsie Sunderland

International Congress on Environmental Modelling and Software

Models have emerged as essential tools in environmental management, whether used to further the understanding of complex environmental processes or to inform decisions for environmental planning, remediation, protection or regulation. However, their utility aside, there is also an acknowledgment of their limitations. The question is not whether or not to use models, but rather how best to develop and use models to arrive at credible, defensible and robust decisions and what attributes make a model useful for a given situation. To understand the role of models and decision support tools in environmental management, we must first consider the different types …

Two-Dimensional Hydraulic Modeling Approach To Linking Stream Morphology And Aquatic Habitat Quality, J. S. Clark, W. C. Hession, Donna M. Rizzo, J. P. Laible, M. C. Watzin

International Congress on Environmental Modelling and Software

A two-dimensional hydrodynamic model (River2D) was utilized to evaluate the relationship between geomorphic condition (as estimated using an existing rapid assessment protocol) and instream habitat quality in small Vermont streams. Six stream reaches ranging in geomorphic condition from good to poor according to the protocols were utilized for this study. We conducted detailed topographic surveys, quantified bed substrate, and measured velocity values during baseflow conditions. The reach models were calibrated with realistic roughness values based on field observations and pebble counts. After calibration, the flows were scaled up to median and bankfull flows for additional analysis. The weighted usable area …


Generic Simulation Models For Facilitating Stakeholder Involvement In Water Resources Planning And Management, Daniel P. Loucks Jul 2006

Generic Simulation Models For Facilitating Stakeholder Involvement In Water Resources Planning And Management, Daniel P. Loucks

International Congress on Environmental Modelling and Software

The models discussed in this workshop have many features in common, and some that differ. All are what we commonly call decision support systems for analyzing alternative water, and, in some cases, watershed management alternatives. All are interactive, i.e., they use graphic interfaces and are menu driven. After some training interested stakeholders can explore questions and assumptions using these tools. Each model is designed to be flexible enough to fit most if not all water resource systems no matter where located. Each is a tool that can be used, at least as a first step, in the identification and evaluation …

Landscape Modeling And Spatial Optimization Of Management Practices To Restore Water Quality In The St. Albans Bay Watershed, Vermont, Erica Gaddis, Alexey Voinov

International Congress on Environmental Modelling and Software

Diffuse (non-point source) pollution from urban stormwater and agricultural runoff are among the leading causes of water pollution in the United States. Currently, most management plans that address diffuse pollution are driven by dissociated economic, political and ecological interests that are difficult to reconcile. Integrated watershed management aims to protect and improve water resources while considering economic and social concerns in the community. Participatory environmental management requires tools, such as landscape models, that can be used to visualize and evaluate the possible outcomes of various management strategies. The overall objective of this project is to develop and implement a framework …


Bottom-Up, Decision Support System Development : A Wetland Salinity Management Application In California's San Joaquin Valley, N. W. T. Quinn Jul 2006

Bottom-Up, Decision Support System Development : A Wetland Salinity Management Application In California's San Joaquin Valley, N. W. T. Quinn

International Congress on Environmental Modelling and Software

Seasonally managed wetlands in the Grasslands Basin of California’s San Joaquin Valley provide food and shelter for migratory wildfowl during winter months and sport for waterfowl hunters during the annual duck season. Surface water supply to these wetland contain salt which, when drained to the San Joaquin River during the annual drawdown period, negatively impacts downstream agricultural riparian water diverters. Recent environmental regulation, limiting discharges salinity to the San Joaquin River and primarily targeting agricultural non-point sources, now addresses return flows from seasonally managed wetlands. Real-time water quality management has been advocated as a means of matching wetland return flows …

Modeling Short-Term Epidemics And Intervention Strategies In Cities, Valeriy Perminov, M. Kornilina

International Congress on Environmental Modelling and Software

Individual-based model (IBM) for simulation of urban influenza epidemic is constructed. In comparison with the past similar models the proposed model has new features: 1)it bases on a real demographical and social infrastructure statistical data; 2)its contacts network is built up with the help of daily routines of different age and social groups of residents. Test simulations were carried out with the use of demographical data on the population of Dresden (Germany). The results obtained showed that the proposed model can be used for the simulation of different epidemics and intervention strategies to contain epidemic or to weaken its consequences.

Uncertainty Management, Spatial And Temporal Reasoning, And Validation Of Intelligent Environmental Decision Support Systems, Miquel Sànchez-Marrè, Karina Gibert, Rick Sojda, Jean-Philippe Steyer, Peter Struss, Ignasi Rodríguez-Roda

International Congress on Environmental Modelling and Software

There are inherent open problems arising when developing and running Intelligent Environmental Decision Support Systems (IEDSS). During daily operation of IEDSS several open challenge problems appear. The uncertainty of data being processed is intrinsic to the environmental system, which is being monitored by several on-line sensors and off-line data. Thus, anomalous data values at data gathering level or even uncertain reasoning process at later levels such as in diagnosis or decision support or planning can lead the environmental process to unsafe critical operation states. At diagnosis level or even at decision support level or planning level, spatial reasoning or temporal …

Neural Identification Of Fuzzy Anomalies In Pressurized Water Systems, Joaquín Izquierdo, R. Pérez, P. A. López, P. L. Iglesias

International Congress on Environmental Modelling and Software

The objective of a Water Supply System (WSS) is to convey treated water to consumers through a pressurized network of pipes. A number of meters and gauges are used to take continuous or periodic measurements that are sent via a telemetry system to the control and operation centre and used to monitor the network. Using this typically limited number of measures together with demand predictions the state of the system must be assessed. Suitable state estimation is of paramount importance in diagnosing leaks and other anomalies in WSS. But this task can be really cumbersome, if not unattainable, for human …

Future Solutions: Integrated Models For Sea And Other Land-Use Decision-Making., Ruth Waldick, David Brunckhorst, Ian Campbelld, Jeff Carmichael

International Congress on Environmental Modelling and Software

Since policies should reflect societal values and aspirations, decision-making would benefit from tools that allow consideration of all entities that contribute to, or are affected by decisions. At a minimum, policy should include those key economic, social, and environmental activities taking place within a geophysically relevant area. The barriers that impede the development of integrated modeling programs that try to include many of the processes and outcomes of interest in studying a problem represent a series of common challenges associated with most integrative and cross-jurisdictional projects. Although computer-based modeling and scenario tools can inform the decision-making process, the scope of …

A Model For Investment Decision Support Based On Multicriteria Analysis, Irina Glazyrina Jul 2006

A Model For Investment Decision Support Based On Multicriteria Analysis, Irina Glazyrina

International Congress on Environmental Modelling and Software

The conventional implementation of polluter pays principle (PPP) in many countries is based on the use of an environmentaltax, which is determined proportionally to the amount of emissions of the polluting substances. Using aspecific mathematical model this study shows that this practice is not adequate for the real negative impact if thepollutant accumulates to a stock in the environment. Moreover, in many cases there is a danger of an unavoidableconflict between the interests of society as a whole and the interests of private business, generated by these proceduresof PPP implementation. This paper also presents a mathematical formula (obtained as an …
