International Congress on Environmental Modelling and Software
The majority of process-based models of thecarbon cycle in forest ecosystems aredeterministic. Very few components have beenimplemented in these models to represent theuncertainty that may result from natural variation,model structure and parameter estimates. Thereare many sources of natural variation in thecarbon cycle of forest ecosystems. The mainsources of variation occur in the soil organicmatter (SOM) in terms of quantity and quality,both of which vary according to vegetation type,climatic conditions, soil characteristics (textureand structure) and carbon fluxes. For instance, thelitterfall rate and periodicity influencesignificantly the carbon input in the soil organicand mineral horizons. The litter carbon andnutrient contents affect both the …
Cell-Devs Modeling Of Environmental Applications, Gabriel Wainer
Cell-Devs Modeling Of Environmental Applications, Gabriel Wainer
International Congress on Environmental Modelling and Software
Recently, different research teams used Cellular models for the analysis of environmental systemsusing Cellular models. Some of these techniques are based on Cellular Automata, which have some problemsconstraining its power, usability and feasibility for studying large complex systems. In other cases, the CellularAutomata have been combined with the DEVS (Discrete-Event Systems Specifications) formalism, which requiresexpertise in advanced programming techniques, visualization, distributed computing, etc. Instead, theCell-DEVS formalism and the CD++ toolkit Cell-DEVS simplify the construction of complex cellular modelsby allowing simple and more intuitive model specification. We present the definition of different models, focusingon how to define such applications using Cell-DEVS …

A Dynamic Model For Sustainable River Basin Management., Paula A. Silva, Paula Antunes, Daniel Borrego, Jojo Rocha, Nuno Videira, Rui Santos
International Congress on Environmental Modelling and Software
The European Water Framework Directive (WFD) introduced an integrated perspective in water resources management, based on an approach where the river basin is the management unit and the active involvement of all affected parties by its river basin management plan is clearly encouraged. The integrated perspective is required to develop sustainable resource management strategies adapted to the institutional, cultural and legal tradition in a region, taking into account the human dimension of the problem. A dynamic model capable of integrating quantitative and qualitative data and relationships between technical, ecological, economic and social driving forces, typical of water resources management problems, …

The Role Of Artificial Neural Network Models In Developing A Regional Wastewater Reclamation Facility For Beaufort, Sc, Usa, Paul A. Conrads, Edwin Roehl, William Martello, Edward Saxon
International Congress on Environmental Modelling and Software
Beaufort and Jasper Counties are two rapidly growing coastal counties in South Carolina. According to the 2000 census, the region grew by 40 percent during the preceding 10 years. The population growth has increased the quantity of wastewater in the area. The Beaufort River is a complex tidal river system that is home to shellfish grounds, fisheries nursery habitats, and extensive recreation by the local community. The river also serves as receiving water for treated wastewater from military and civilian wastewater reclamation facilities (WRF). Although not uncommon for coastal areas, the river is on the South Carolina list of impaired …
Problems And Solutions In Up- And Down-Scaling In Environmental Modelling For The Policy Scale, Ulrich Leopold, Peter Finke, Reimund Roetter
Problems And Solutions In Up- And Down-Scaling In Environmental Modelling For The Policy Scale, Ulrich Leopold, Peter Finke, Reimund Roetter
International Congress on Environmental Modelling and Software
Environmental models are mostly developed to study processes at a certain scale. They are increasingly applied for analyses to support decision making of policy makers on natural resource and environmental risk management. Usually the policy scale differs from the scale the models are developed for as processes have to be taken into account occurring at various scales. In addition, many models were developed for research purposes rather than for policy support. As a consequence, several models are often combined into model chains to arrive at estimates for the policy scale, each sub-model describing a sub set of processes and only …

Current Development And Application Of The Modular Java Based Model Jams To Meet The Targets Of The Eu-Wfd In Germany., Ulrike Bende-Michl, Manfred Fink, Sven Kralisch, Wolfgang-Albert Flügel, Peter Krause
International Congress on Environmental Modelling and Software
The European Water Framework Directive (EU-WFD), implemented in the year of 2000, requires general ecological protection and a minimum chemical standard to be obtained in all European surface waters at different spatial and temporal scales. To meet these requirements the knowledge of spatially distributed sources and movements of contaminants, e.g. nutrients entries on stream systems is essential. In Germany some major water quality problems are related to non-point sources of nitrogen export. For a collaborative pilot study the need was identified to integrate solute turnover and transport processes into the object-oriented Java based JAMS modeling framework (Jena Adaptable Modelling System). …
Modelling Farmer Decision Making For Natural Resource Management Outcomes, Brett A. Bryan, J. Ward, Neville D. Crossman
Modelling Farmer Decision Making For Natural Resource Management Outcomes, Brett A. Bryan, J. Ward, Neville D. Crossman
International Congress on Environmental Modelling and Software
This paper presents a conceptual modelling and simulation methodology that incorporates dryland farmer decision making into regional- and landscape-level natural resource management (NRM) planning. Decision making for many NRM on ground actions is made at the farm level so it makes sense to incorporate farmer behaviour into regional planning for meeting regional environmental objectives. Our model applies multi-attribute farmer utility functions within an agent-based simulation environment to model temporal change in land use and landscapes resulting from farmer implementation of on ground NRM actions. Farmer decision profiles are characterized using a survey of over 500 farmers. Landscape futures can also …
Comparison Of Linear And Non-Linear Pls Methods For Soft-Sensing Of An Sbr For Nutrient Removal, K. Villez, D. S. Lee, C. Rosen, Peter A. Vanrolleghem
Comparison Of Linear And Non-Linear Pls Methods For Soft-Sensing Of An Sbr For Nutrient Removal, K. Villez, D. S. Lee, C. Rosen, Peter A. Vanrolleghem
International Congress on Environmental Modelling and Software
Despite of promising results in research, advanced control strategies fail to gain trust in wastewater treatment practice. Due to the sensitivity of the biological processes to disturbances, operators are often unable to find the causes of faults due to the lack of effective real-time on-line monitoring. Strategies for on-line monitoring are therefore essential to enhance biological process control. Therefore, a suitable multivariate soft-sensor is desired for fault detection and control for a pilot-scale sequencing batch reactor (SBR) system to allow effluent quality to be estimated well before off-line analysis is finished. For this purpose, several multivariate methods are available, including …

Spatial Estimations Of Air Pollution In Street Canyons By Lidar Measurements, L. Matejicek, Jana Konradova
International Congress on Environmental Modelling and Software
Air pollution of urban areas can be explored by direct monitoring, mathematical modeling and physical simulation in the wind tunnels. Complex analysis requires using of all mentioned approaches together. To integrate the data inputs and outputs, which include spatio-temporal interactions, the Geographic Information System (GIS) is used for database management and spatial analysis. The geodatabase is primarily developed to support spatial interpolations of LIDAR measurements in the street canyons. The LIDAR measurements provide the information about the distribution of pollutants in the points along the beam trajectories. As the examples, the sets of NO2 spatial measurements are performed in the …
Mike Basin, David Wood
Mike Basin, David Wood
International Congress on Environmental Modelling and Software
MIKE BASIN addresses water allocation, conjunctive use, reservoir operation, or water quality issues. It couples ArcGIS with hydrologic modeling to provide basin-scale solutions. The MIKE BASIN philosophy is to keep modeling simple and intuitive, yet provide in-depth insight for planning and management. In MIKE BASIN, the emphasis is on both simulation and visualization in both space and time, making it appropriate for building understanding and consensus. MIKE BASIN is a quasi-steady-state mass balance model, allowing for routed river flows. The water quality solution assumes purely advective transport. Decay during transport can be modeled. The groundwater description uses the linear reservoir …

Confronting Edss-Maintenance Validation, Clàudia Turon, Joaquim Comas, Ulises Cortés, Manel Poch
International Congress on Environmental Modelling and Software
Daily operation and maintenance tasks are needed to guarantee the correct performance of Constructed Wetlands (CWs). The definition of these activities is a complex task since these actions vary according to the technology, the configuration and the design of the wastewater treatment plant, the community characteristics and the features of the receiving media. To support the definition of these actions an Environmental Decision Support System (EDSS) has been constructed (EDSS-maintenance). The methodology used to develop EDSS-maintenance is based on the following 5 steps: environmental problem analysis, data and knowledge acquisition, model selection, model implementation and validation. The first 4 steps …

Model-Based Identification And Scaling Indicators Of Landscape Processes: State-Of-The-Art And Problem-Oriented Solutions, Martin Volk, K. Schulz, Ralf Seppelt, Sven Lautenbach
International Congress on Environmental Modelling and Software
The ability to transfer processes, local conditions and assessment methods between different spatial scales plays an important role in various fields of environmental sciences and planning practice. Besides a fundamental lack of general scaling theories different approaches are currently used and investigated. First, local scale process understanding is simply used at larger scales and spatial explicit information are derived by suitable indicators or transfer functions. In order to represent small scale spatial variability at larger scales sophisticated aggregation methods have been developed, but due to very restrictive assumptions, have only successfully been applied in very few areas (e.g. groundwater hydrology). …
Sensitivity Analysis Of Historical Aerial Photography: A Case Study Of Barrier Island Marshes, Joanne N. Halls, Lindsey M. Kraatz
Sensitivity Analysis Of Historical Aerial Photography: A Case Study Of Barrier Island Marshes, Joanne N. Halls, Lindsey M. Kraatz
International Congress on Environmental Modelling and Software
Barrier islands and coastal salt marshes are complex ecosystems that move and change throughtime in response to many factors. For example, hurricanes bring strong winds, rain, and storm surge whichcan greatly change the distribution of surficial deposits. Through time the islands can migrate and inletschange their positions. A study of back-barrier salt marshes in southeastern North Carolina, USA, wasconducted to map changes in the distribution and fragmentation characteristics of the marshes. Topsail Islandand Masonboro Island were chosen as comparative study sites since Topsail has had increasing urbanizationsince the 1930s while Masonboro is a protected, undeveloped, island. By gathering, rectifying, interpreting,and …
Model Averaging, Equifinality And Uncertainty Estimation In The Modelling Of Ungauged Catchments, J. P. C. Reichl, F. H. S. Chiew, A. W. Western
Model Averaging, Equifinality And Uncertainty Estimation In The Modelling Of Ungauged Catchments, J. P. C. Reichl, F. H. S. Chiew, A. W. Western
International Congress on Environmental Modelling and Software
The problem of estimating runoff in ungauged catchments remains an important but elusive one. Previous studies suggest that there are two important properties common to rainfall-runoff models: over-parameterisation, leading to parameter covariance; and equifinality, the existence of multiple parameter sets which reproduce the streamflow adequately. Both reduce parameter identifiability, impeding identification of relationships between model parameter values and catchment characteristics that would otherwise be useful for regionalisation. This study investigates the use of a model averaging framework to circumvent this problem. Multiple behavioural parameter sets arising from Monte-Carlo simulation are used from each catchment in order to retain information about …

International Congress on Environmental Modelling and Software
Land cover changes over large areas can be monitored using remote sensing (RS) technology. These changes are one of the key driving forces for ecosystem carbon (C) dynamics. We applied the General Ensemble Biogeochemical Modeling System (GEMS) using a top-down, remote sensing (RS) driven mechanism to estimate forest C fluxes in the Laurentian Plains and Hills ecoregion in the northeastern United States for the period of 1972-2000. Disturbances such as forest stand replacement were detected on 30 randomly-located 10-km by 10-km sampling blocks using Landsat imagery at 60-m resolution. Spatially explicit modeling of carbon dynamics in GEMS was organized using …

Tools To Support A Model-Based Methodology For Benefit/Cost/Risk Analysis Of Wastewater Treatment Systems, Lorenzo Benedetti, Davide Bixio, Filip Claeys, Peter A. Vanrolleghem
International Congress on Environmental Modelling and Software
This paper presents a set of tools developed to support an innovative four-step methodology to design and upgrade wastewater treatment systems. For the first step of data collection and data reconstruction, two different tools have been developed, one for situations where data are available (using data reconstruction methods) and another for situations where no data are (yet) available (based on a simple draining catchment model driven by actual local rain series). The second step, i.e. model building, implied the development of a new simulation platform and of grid software to deal with the considerable simulation load generated by the third …
Numerical Simulation Of Flow And Tracer Transport In A Disinfection Contact Tank, C. Gualtieri
Numerical Simulation Of Flow And Tracer Transport In A Disinfection Contact Tank, C. Gualtieri
International Congress on Environmental Modelling and Software
Chlorine is extensively used to disinfect drinking water supply. However, the design of chlorine contact tank is usually based on the volume displacement criterion, paying attention that detention time would be at least of half an hour. This criterion relies upon the assumption that plug-flow conditions hold along the tank. However, the existence and arrangement of baffles in the tank, and the tank inlet and outlet configurations can result in a much more complex flow pattern, where turbulent mixing, dead-zones and short-circuiting exist. This situation could result in an inefficient use of chlorine due to the formation of potentially carcinogenic …

Imagine – Scenario Development For Environmental Impact Assessment Studies, T. Wagener, Y. Liu, S. Stewart, H. Hartman, M. Mahmoud
International Congress on Environmental Modelling and Software
Scenario analysis is a process of evaluating possible future events through the consideration of alternative possible (though not equally likely) outcomes (scenarios). The analysis is designed to enable improved decision-making and assessment through a more complete consideration of possible outcomes and their implications. The development of strategies for water resources planning and management and the assessment of impacts of potential environmental change are often guided by analyzing multiple future scenarios within an Integrated Modeling (IM) framework, usually driven by forcing derived from global climate models and/or possible future socio-economic changes. The process of scenario development involves making explicit and/or implicit …

International Congress on Environmental Modelling and Software
The aim of this paper is to discuss scientific challenges and new possibilities for a better modelling of consequences of land use changes in heterogeneous landscapes on ecosystem functions in space and time. The landscape or regional scale means an area of about 100 km2 up to some 1000 km2. Main problems on this scale are high complexity, structural diversity, ecological heterogeneity and uncertainty in data, in understanding of the process dynamic and by uncertainty in models.
Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson
Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson
International Congress on Environmental Modelling and Software
Experimental data mining and image segmentation approaches are developed to add insight towards aerial image interpretation for defoliation survey procedures. A decision tree classifier generated with a data mining package, WEKA [Witten and Frank, 2005], based on the contents of a small number of training data points, identified from known classes, is used to predict the extents of regions containing different levels of tree mortality (severe, moderate, light and non attack) and land cover (vegetation and ground surface). This approach is applicable to low quality imagery without traditional image pre-processing (e.g., normalization or noise reduction). To generate the decision tree, …

Tornado: A Versatile And Efficient Modelling And Virtual Experimentation Kernel For Water Quality Systems, Filip Claeys, Dirk J. W. De Pauw, Lorenzo Benedetti, Ingmar Nopens, Peter A. Vanrolleghem
International Congress on Environmental Modelling and Software
Recently, a new kernel for modelling and virtual experimentation (i.e. any evaluation of a model) in the domain of water quality management was developed. This kernel was named “Tornado” and will be included in the new generation of the WEST product family, as well as in several other products (e.g. DHI’s MOUSE-TRAP) and projects. Most important issues during development were versatility and efficiency. This paper focuses mainly on the rationale for the new development, and the major features of the resulting kernel. It is argued that classical approaches (such as the adoption of MATLAB/SIMULINK, custom FORTRAN codes and/or domain-specific simulators) …

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 …

Nesting Genetic Algorithms To Solve A Robust Optimal Experimental Design Problem, Dirk J. W. De Pauw, Peter A. Vanrolleghem
International Congress on Environmental Modelling and Software
When calibrating a (dynamic) model, one is often faced with a lack of information-rich data. Without such data, there is little hope in obtaining accurate parameter estimates. In order to improve the situation, optimal experimental design for parameter estimation (OED-PE) can be employed. The main drawback of the classical OED-PE methodology is that values for the model parameters need to be provided in order to obtain an optimal design. If the values of the model parameters are highly uncertain, robust OED-PE should be preferred, yielding a design which guarantees a certain information content given the parameter uncertainty. This approach adds …

International Congress on Environmental Modelling and Software
The Riparian Particulate Model (RPM) [Newham et al., 2005] is a simple conceptual model of particulate trapping in riparian buffer zones. The model represents the key processes of settling, infiltration and adsorption which control particulate trapping. The model is intended for use by catchment managers and researchers to quantify the effectiveness of riparian buffers at site and catchment-scales. Application of the model enables assessment of the likely effects of riparian buffer establishment and assists in the prioritisation of investment. The RPM operates at a daily time interval. It is sensitive to the effects of consecutive pollutant loading events and variations …
