Multivariate Spatio-Temporal Clustering (Mstc) As A Data Mining Tool For Environmental Applications, Forrest M. Hoffman, William W. Hargrove, Richard T. Mills, Salil Mahajan, David J. Erickson, Robert J. Oglesby

International Congress on Environmental Modelling and Software

The authors have applied multivariate cluster analysis to a variety of environmental science domains, including ecological regionalization; environmental monitoring network design; analysis of satellite-, airborne-, and ground-based remote sensing, and climate model-model and model-measurement intercomparison. The clustering methodology employs a k-means statistical clustering algorithm that has been implemented in a highly scalable, parallel high performance computing (HPC) application. Because of its efficiency and use of HPC platforms, the clustering code may be applied as a data mining tool to analyze and compare very large data sets of high dimensionality, such as very long or high frequency/resolution time series measurements or …

Towards An Agent-Based Design For The Management Of Urban Wastewater Systems, M. Aulinas, Manel Poch, Ulises Cortés

International Congress on Environmental Modelling and Software

Urban Wastewater Systems (UWS) have an important role in nowadays growing and urbanized areas. The management of the water and wastewater cycle in these areas is complex since wastewater sources are both heterogeneous and rapidly changing. Moreover, it implies to deal with different spatial and temporal references and to adapt to the changing conditions that might appear in both natural and urban environments. New paradigms are required to be undertaken when designing and modelling this complex dynamic system, since the need to communicate the embedded elements is essential for an efficient and effective management and a better understanding of the …

An Activity Based Cellular Automaton Model To Simulate Land Use Changes, Jasper Van Vliet, Hedwig Van Delden Jul 2008

An Activity Based Cellular Automaton Model To Simulate Land Use Changes, Jasper Van Vliet, Hedwig Van Delden

International Congress on Environmental Modelling and Software

This paper proposes a spatial explicit model for land use dynamics, based on activities, which can represent for example population or jobs. In land use models based on constrained cellular automata (CA), the total area per land use is defined exogenously, while the model computes the allocation based on transition rules. The activity based model is a CA model, but it is constrained by activities instead of areas. Each time step, activities are distributed over cells based on transition rules. The CA transition rules comprise the effects of the activity in the neighbourhood, the land use of a cell, externalities …

Evolvable Biological Interfaces: An Outline Of The New Computing System, Igor Balaž, Dragutin T. Mihailović Jul 2008

Evolvable Biological Interfaces: An Outline Of The New Computing System, Igor Balaž, Dragutin T. Mihailović

International Congress on Environmental Modelling and Software

In this paper, we represent architecture of a new individual-based model of evolvable biological interfaces. The model is based on three parts: mutable coding sequence, individual agents produced by the coding sequence and external environment represented by various virtual substances. Agents are able to recognize external substances and to perform transformations on them. However, unlike general computational scheme currently used in evolutionary computation which is based on predefined list of actions, where each action have predefined fitness value defined strictly within current problem, the recognition and corresponding transformation in this model are organized in completely different way. Here we merged …

On The Role Of Pre And Post-Processing In Environmental Data Mining, Karina Gibert, Joaquín Izquierdo, Geoffrey Holmes, Ioannis N. Athanasiadis, Joaquim Comas, Miquel Sànchez-Marrè

International Congress on Environmental Modelling and Software

The quality of discovered knowledge is highly depending on data quality. Unfortunately real data use to contain noise, uncertainty, errors, redundancies or even irrelevant information. The more complex is the reality to be analyzed, the higher the risk of getting low quality data. Knowledge Discovery from Databases (KDD) offers a global framework to prepare data in the right form to perform correct analyses. On the other hand, the quality of decisions taken upon KDD results, depend not only on the quality of the results themselves, but on the capacity of the system to communicate those results in an understandable form. …

Creating Robust Sensor Networks - Architecture And Infrastructure, Gerald Schimak, Thomas Usländer, D. Havlik, R. M. Argent

International Congress on Environmental Modelling and Software

Significant unregulated development is occurring in sensor devices, protocols and sensor networks especially in the areas of air and water quality monitoring and management where the focus has been on human health and exposure impacts. Satellite technology is well established as a means of deploying sensors. However, for monitoring of air and water we lack the interconnectivity of both in-situ and remote sensing devices that link to interoperable information systems. One reason for this deficiency is the lack of a sensor network infrastructure generic enough to support this interoperability and interconnectivity. This workshop will explore the architectural aspects of creating …

Influence Of The Uncertainties Of Monitoring Data On Model Calibration And Evaluation, A. Ullrich, Martin Volk, G. Schmidt Jul 2008

Influence Of The Uncertainties Of Monitoring Data On Model Calibration And Evaluation, A. Ullrich, Martin Volk, G. Schmidt

International Congress on Environmental Modelling and Software

The model-based prediction of the impact of different land management on nutrient loading requires measured nutrient flux data. Thereby the accurate calibration and evaluation of the models need an adequate data base in form of monitoring data. Uncertainties in the monitoring data influence the calibration and thus the parameter settings which affect the modelling results. Hence, we compared three different time-based sampling strategies and four different load estimation methods for model calibration and compared the results. For our study we used the river basin model SWAT (Soil and Water Assessment Tool). Study area is the intensively used loess-dominated Parthe watershed …

Evaluating Consistency Of Biosphere Models: Software Tools For A Web-Based Service, G. A. Alexandrov, T. Matsunaga Jul 2008

Evaluating Consistency Of Biosphere Models: Software Tools For A Web-Based Service, G. A. Alexandrov, T. Matsunaga

International Congress on Environmental Modelling and Software

A biosphere model is a geographical extension of an ecosystem model, and so modelling ecosystems at global scale we are facing the same problem as at the local scale -- structural uncertainty. The structural uncertainty includes competing conceptual frameworks, lack of agreement on model structure, ambiguous definitions of system boundaries, inadequate description of significant processes. The typical approach to this problem is assessing the maturity of the underlying science through retrospection of modelling efforts. This displays either consensus building or paradigm shift. In this paper we present a general scheme and software tools for performing such analysis, discuss how this …

Deposition And Resuspension Of Sediments In Near Bank Water Zones Of The River Elbe, S. Prohaska, Bernhard Westrich

International Congress on Environmental Modelling and Software

Catchment processes, such as spatially and temporally distributed rainfall, influence quantity and quality of river runoffs and thus, the transport of particulate sediments and associated contaminants in a river network. During flood events resuspension of contaminated sediments impacts the water quality and thus, it is important to determine the erosion probability of such deposits. The research is focused on the River Elbe deposits in groyne fields and their sediment dynamics. High percentage of contaminated deposits in the groyne fields originate from the tributary Mulde, which discharges high concentrations of arsenic and lead into the Elbe [Kraft, 2007]. Various hydrological scenarios …

Predicting Winners And Losers: Translating Air Pollution Policy Initiatives Into Indicators Of Habitat Quality Change, E. C. Rowe, C. D. Evans, S. Smart, B. A. Emmett

International Congress on Environmental Modelling and Software

Damage to semi-natural habitats due to air pollution has hitherto been quantified using biogeochemical indicators, but predictions of species change are necessary to relate impacts on ecosystems to the habitat quality metrics used in conservation and policy communities. Ongoing pollution by reactive nitrogen (N) is delaying the recovery of acidsensitive ecosystems from sulphur (S) pollution, and causing additional damage through eutrophication. Dynamic soil chemistry models are currently used to set national emissions thresholds for acid pollutants in a UNECE process, using simple targets based on soil pH or acid-base balance. These indicators are however poorly related to conservation targets based …

Two Interacting Environmental Interfaces: Bifurcation In Coupled Asymmetric Logistic Maps, Dragutin T. Mihailović Jul 2008

Two Interacting Environmental Interfaces: Bifurcation In Coupled Asymmetric Logistic Maps, Dragutin T. Mihailović

International Congress on Environmental Modelling and Software

The field of environmental sciences is abundant with various interfaces and it is the right place for application of new fundamental approaches leading towards better understanding of environmental phenomena. For example, following definition of environmental interface by Mihailovic and Balaž [2007], such interface can be placed between natural or artificially built surfaces and atmosphere. In this case, visible radiation provides almost all of the energy received on the environmental interface. Since all the energy transfer processes occurs in the finite time interval the energy balance equation for this environmental interface can be written in terms of finite differences of ground …

Monitoring The Effects Of Human Activities And Environmental Change On A Population System, M. Gámez, I. López, J. Garay, Z. Varga

International Congress on Environmental Modelling and Software

The monitoring and analysis of the processes taking place in an ecosystem is a key issue for a sustainable human activity. A system of populations, as the biotic component of a complex ecosystem is usually affected by the variation of its abiotic environment. Even in nearly natural ecosystems an abiotic effect like climatic implications of global warming may cause important changes in the dynamics of the population system. In ecosystems involving field cultivation or any industrial activity, the abiotic parameter in question may be the concentration of a substance, changing e.g. as a result of pollution, application of a pesticide …

Challenges Of Alpine Catchment Management Under Changing Climatic And Anthropogenic Pressures, Carmen De Jong, P. Masure, T. Barth Jul 2008

Challenges Of Alpine Catchment Management Under Changing Climatic And Anthropogenic Pressures, Carmen De Jong, P. Masure, T. Barth

International Congress on Environmental Modelling and Software

Water resources in mountain areas are particularly important with respect to new and increasing pressures in the headwater areas of catchments. Climate change has resulted in a decrease in precipitation and decrease in groundwater recharge in the western and southern Alps over the last few decades. This is coupled with changing anthropogenic pressures such as an increase in water abstraction for tourism and artificial snow in addition to the water demands of agriculture and hydroelectricity. Water consumption by tourism in winter is several times higher than that of the permanent population. To avoid the development of water shortages with relation …

Comparison Of Control Strategies For Multiobjective Control Of Urban Wastewater Systems, G. Fu, David Butler, Soon-Thiam Khu Jul 2008

Comparison Of Control Strategies For Multiobjective Control Of Urban Wastewater Systems, G. Fu, David Butler, Soon-Thiam Khu

International Congress on Environmental Modelling and Software

In recent years much attention has been paid to integrated management and control of urban wastewater systems. With the application of integrated system modelling tools, overall system performance can be improved to a great extent in terms of receiving water quality, through development of optimal control strategies. Most studies to date, however, have used a single objective to demonstrate the potential benefits. Control of urban wastewater systems is actually a multiple objective optimisation problem, involving balancing different, possibly conflicting objectives required by stakeholders with different interests. This paper compares three different control strategies for multi-objective optimal control of the urban …

Community Modelling, And Data-Model Interoperability, Alexey Voinov, Ilya Zaslavskiy, David Arctur, C. J. Duffy, Ralf Seppelt Jul 2008

Community Modelling, And Data-Model Interoperability, Alexey Voinov, Ilya Zaslavskiy, David Arctur, C. J. Duffy, Ralf Seppelt

International Congress on Environmental Modelling and Software

Community modelling is a promising paradigm to develop complex evolving and adaptable modelling systems that can share methods, data and models more easily within specialized communities. Why then are cooperative modelling communities still quite rare and do not propagate easily? Why has open source been so successful for software development, yet open models are still quite exotic? One difference between software and models is that software shares some common language. Models often use very different principles, theories, and semantics. For example hydrodynamic models, ecological models, and decision support models may have limited commonalities, In these cases, the disciplinary problem being …
