Guidelines For Good Practice In Bayesian Network Modelling, Serena H. Chen, C. A. Pollino Jul 2010

Guidelines For Good Practice In Bayesian Network Modelling, Serena H. Chen, C. A. Pollino

International Congress on Environmental Modelling and Software

Bayesian networks (BNs) are used increasingly to model environmental systems, for reasons including their ability to: integrate multiple issues and system components; utilise information from different sources; and handle missing data and uncertainty. For a model to be of value in generating and sharing knowledge or providing decision support, it must be built using good modelling practice. This paper provides such guidelines to developing and evaluating Bayesian network models of environmental systems. The guidelines entail clearly defining the model objectives and scope, and using a conceptual model of the system to form the structure of the BN, which should be …

Development And Validation Of A Decision Support System For The Integrated Operation Of Membrane Bioreactors, Joaquim Comas, Hèctor Monclús, Giuliana Ferrero, Ignasi Rodríguez-Roda, Luis Sancho, Eduardo Ayesa Jul 2010

Development And Validation Of A Decision Support System For The Integrated Operation Of Membrane Bioreactors, Joaquim Comas, Hèctor Monclús, Giuliana Ferrero, Ignasi Rodríguez-Roda, Luis Sancho, Eduardo Ayesa

International Congress on Environmental Modelling and Software

Membrane bioreactor technology in wastewater treatment and re-use is currently challenging traditional wastewater methods. However, although this technology presents many advantages as in most membrane filtration processes the permeate flux and permeability declines during filtration due to membrane fouling. Therefore controlling membrane fouling is the key issue in MBR operation. Nevertheless, membrane fouling is a very complicated phenomenon that results from multiple causes. Thus an intelligent Decision Support System for the integrated operation of membrane bioreactors has been developed. This Decision Support System, based on empiric and heuristic knowledge, gathers on-line and off-line information about both the biological and physical …

Multi-Scale Modelling Of Ecosystem Services – An Iterative Approach, M. S. Castellazzi, I. Brown, L. Poggio, Alessandro Gimona Jul 2010

Multi-Scale Modelling Of Ecosystem Services – An Iterative Approach, M. S. Castellazzi, I. Brown, L. Poggio, Alessandro Gimona

International Congress on Environmental Modelling and Software

Ecosystems are dependent upon the interactions between the natural environment and human factors. Each different ecosystem service is also associated with varying spatial scales related to their functioning and human benefits. Thus, key requirements for an ecosystem-based approach (EBA) are i) multiple scales, especially landscape scale, ii) flexible method for adaptive response and iii) stakeholders participation. Understanding complex inter-relationships between ecosystem functions and their services requires tools to handle change and uncertainty, notably scenarios and sensitivity analysis. We propose an iterative approach, which is multi-scale and userfocused based upon the LandSFACTS toolkit to generate a suite of land use change …

What Can We Learn From Systems Based Approaches: From Systems Biology To Earth Systems Science?, C. J. A. Macleod

International Congress on Environmental Modelling and Software

Systems based approaches have been developed and applied in a broad range ofdisciplines. These cover a wide range of processes, structures and scales. Ludwig vonBertalanffy is often credited with establishing and developing ‘general systems theory’.The ecosystem based approach to ecology developed by the Odum brothers (EugenePleasants and Howard Thomas) instigated approaches to understanding ecological systemsthat are still advancing within the frameworks of ecosystem services and ecologicalthermodynamics. West Churchman and Russel Ackoff were early pioneers in the field ofoperations research following on from techniques developed during the Second WorldWar. Jay Forrester was also influenced by his work on feedback systems during …

Parameter Optimization And Bayesian Inference In An Estuarine Eutrophication Model Of Intermediate Complexity, P. Ding, C. E. S. Hoyle, M. E. Borsuk

International Congress on Environmental Modelling and Software

The Neuse River Estuary, North Carolina, has been experiencing severe consequences of eutrophication in recent years including excessive algal blooms, low levels of dissolved oxygen, declining shellfish populations, large fishkills, and outbreaks of toxic microorganisms. As in many other marine systems, nitrogen has been identified as the pollutant of concern in the estuary because it is believed to stimulate the excessive algal growth that is at the root of other ecological problems. A model incorporating the mechanisms of algal growth and nutrient consumption in the Neuse River Estuary is formulated mathematically and implemented in the computer software AQUASIM. Key model …

Towards Adaptive Control Of Landscape Biodiversity, J. Gary Polhill, Andrew Jarvis, Alessandro Gimona, Nicholas M. Gotts Jul 2010

Towards Adaptive Control Of Landscape Biodiversity, J. Gary Polhill, Andrew Jarvis, Alessandro Gimona, Nicholas M. Gotts

International Congress on Environmental Modelling and Software

This paper reports work using a coupled agent-based model of land use changeand species metacommunity model (FEARLUS-SPOMM) to explore biodiversity incentivemechanisms using adaptive control algorithms. Existing work at the LancasterEnvironment Centre has shown that such algorithms can help in analysing the adaptivecapabilities of climate-related policy interventions under uncertainty. In particular,feedback control is a practical approach that mimics many recognisable features of adaptivedecision making processes, including the sequential review of models and policies in thelight of new observations. In a companion paper, we show that FEARLUS-SPOMM showsnonlinear dynamics in the relationship between agricultural incentives and biodiversityoutcome. In this pilot study, we …

Carma: Scalability With Approximate-Model-Based Adaptation, John D. Hastings, Alexandre V. Latchininsky, Scott P. Schell Jul 2010

Carma: Scalability With Approximate-Model-Based Adaptation, John D. Hastings, Alexandre V. Latchininsky, Scott P. Schell

International Congress on Environmental Modelling and Software

Many complex physical systems such as biological systems are characterized both by incomplete models and limited empirical data. Accurate prediction of the behavior of such systems requires exploitation of multiple, individually incomplete, knowledge sources. Our approach, called approximate-model-based adaptation, utilizes case-based reasoning to provide an approximate solution and model-based reasoning to adapt this approximation into a more precise solution. This approach is implemented in CARMA, a decision-support system for grasshopper infestation advising which models experts and has been successfully used since 1996. Initially focused on rangeland grasshoppers within the state of Wyoming, CARMA’s capabilities have been extended to support the …

Environmental Flow Requirements (Efrs) Related To Preference Of Phytoplankton In The Yellow River Estuary (Yre) Based On An Ecohydrodynamic Model, R. Zhao, Z. F. Yang, T. Sun

International Congress on Environmental Modelling and Software

The response of ecological processes to hydrological processes is a critical issue in the assessment of environmental flow requirements in estuaries. Considering its representative function of the primary productivity in estuaries, the phytoplankton community was selected as the bioindicator to indicate the variation of ecosystems influenced by hydrological processes in estuaries. Based on the regression analysis, a response relation model was established for describing the relationship between characteristics of phytoplankton communities (chlorophyll a, Fucoxanthin, chlorophyll b, and pyridinin) and indicating factors including salinity, COD, ammonia nitrogen, and dissolved oxygen. The biomass objective of high nutritional level organisms, the biomass of …

International Congress on Environmental Modelling and Software

Brazilian psiculture has been increasing about 30% per year, having as main factors its profitability and source of quality protein. Its strong interaction with water resources and its interference on the biodiversity turns it both potentially exposed to, as well as, source of negative environmental impacts, requiring the adoption of less impactant management practices. The producer needs information on these practices and computer tools that allow access to them in a single repository could motivate the fast incorporation of these activities to the property. Despite of African origin, the tilapiculture is nowadays present at a large part of Brazilian territory, …

A Geosimulation Tool To Assess Intervention Scenarios In Relation To The Spread Of Infectious Disease And Environmental Factors, Mondher Bouden, Bernard Moulin, Pierre Gosselin Jul 2010

A Geosimulation Tool To Assess Intervention Scenarios In Relation To The Spread Of Infectious Disease And Environmental Factors, Mondher Bouden, Bernard Moulin, Pierre Gosselin

International Congress on Environmental Modelling and Software

Several approaches have been proposed to model and simulate the spread ofinfectious diseases such as the West Nile virus (WNV). However, these approaches such asmathematical modeling and cellular automata have some weaknesses when trying to modeland simulate the influence of geographic and climatic features on the disease spread and thespatio-temporal interactions of various kinds of actors (e.g. mosquitoes, birds, mammalsand humans in the WNV case). In this context, we propose to apply a geosimulationapproach to remedy some shortcomings of current methods. Using such an approach wedeveloped WNV-MAGS, a tool allowing public health decision policy makers to assessseveral intervention scenarios in …

Soil Total Organic Carbon, Δ13c Values And Their Responses To The Soil Core Transferring Experiment From High- To Low-Elevation Forest Along Natural Altitudinal Transect Of Old Temperate Volcanic Forest Soils, Zhang Xin-Yu, Meng Xian-Jing, Fan Jin-Juan, Gao Lu-Peng, Sun Xiao-Min

International Congress on Environmental Modelling and Software

In this study, the responses of soil organic carbon and δ13C values to soil warming were conducted by relocating intact soil cores from high- to low-elevation forests for one year along a natural altitudinal transect in the northern slope of Changbai Mountain. As expected, the soil-core relocation caused significant increase in soil temperature but made no significant effect on soil moisture. The results showed that after one year incubation, soil relocation significantly decreased TOC contents, and δ13C decreased. Pearson correlation analysis demonstrates that TOC content was negatively related to soil temperature but positively related to soil moisture. After one-year simulated …

Development Of A Modular Environmental Decision Support System For The Integrated Management Of The Urban Wastewater Cycle At River Basin Scale, D. Murlà, A. Monistrol, Manel Poch, D. Sunyer

International Congress on Environmental Modelling and Software

Most of Urban Wastewater Systems (UWS) have been managed separately, without considering any interaction between sewer systems, Wastewater Treatment Plants (WWTPs) and the receiving waters. Nowadays, the conventional practice has changed, introducing the integrated management concept into the river basin scale. The goal of the project is to develop a modular Environmental Decision Support System (EDSS) to optimise the integrated management of the UWS based on a rule based system as the reasoning core and a Knowledge Base, easily represented by means of decision trees and fully opened. The EDSS, based upon expert knowledge and simulation results, will allow proposing …

The Northern-Global Climate Change Adaptation Dialogue, J. I. Maclellan Jul 2010

The Northern-Global Climate Change Adaptation Dialogue, J. I. Maclellan

International Congress on Environmental Modelling and Software

Although climate change adaptation can occur over various political, social, and institutionalscales, the majority of adaptation decisions take place at the local level where an intimate understanding ofthe particularities of local circumstances (i.e. successful responses to past extremes events) exist alongsidea lack of formalised expertise in projecting and analyzing future possibilities. The relationship between theexperts who produce counterfactual knowledge, and the individuals who apply it, is thus central to thechallenge of responding to climate change successfully. I present a deliberately polarized caricature of thisrelationship in an attempt to facilitate knowledge exchange (i.e. to identify barriers to knowledgeexchange). Through bibliometric analysis …

Evaluation Of The Changed Properties Of Aquatic Animals After Dam Construction Using Ecological Network Analysis, Chen Shaoqing, Liao Xueqin, Yang Jin, Chen Bin Jul 2010

Evaluation Of The Changed Properties Of Aquatic Animals After Dam Construction Using Ecological Network Analysis, Chen Shaoqing, Liao Xueqin, Yang Jin, Chen Bin

International Congress on Environmental Modelling and Software

Dam construction results in variations of hydrology, river morphology and habitat and thebiota associated with the reservoir change significantly compared to the assemblage before damconstruction in order to match these changed environmental conditions. Some attempts so far havebeen made to ascertain the changed properties of aquatilia due to dam construction. Most of them,however, were focused on perturbances to single factors, such as rearing habitats, reproduction andmigration routes, etc. Few have been done on the performance of aquatilia from the whole-ecosystemperspective. Herein, we evaluate the structural properties of aquatic animals and their complexecological relationships within the ecosystem before and after dam …

The Application Of Artificial Neural Network For Forecasting Dam Spillage Events., Anita Talib, Yahya Abu Hasan Jul 2010

The Application Of Artificial Neural Network For Forecasting Dam Spillage Events., Anita Talib, Yahya Abu Hasan

International Congress on Environmental Modelling and Software

Artificial Neural Network (ANN ) is applied for forecasting of dam spillage using a 10year hydrological dataset of Ahning Dam in the northern Malaysia at the Pedu-Mudaarea. During the rainy season, the Ahning Dam will overflow due to heavy rainfall.Increased siltation due to logging could contribute to worsen the overflow during thistime. This will lead to increasingly destructive floods downstream. Rainfall in the Pedu-Muda area is not constant. It is highly influenced by the monsoon seasons. During the dryseason, the dams may dry up. Siltation will further hamper the dams’ capability to storewater for irrigation.This study has shown that a …

Fast Variable Selection For Extreme Values, A. Phatak, C. Chan, H. Kiiveri Jul 2010

Fast Variable Selection For Extreme Values, A. Phatak, C. Chan, H. Kiiveri

International Congress on Environmental Modelling and Software

In this paper, we outline and explore the use of RaVE, a sparse variable selectionmethod that can be used for selecting variables when modelling extreme values. We illustrate itsuse by modelling the location parameter of a series of length 49 of annual rainfall maxima at twostations in North-West Western Australia. The ensemble of potential predictors consists of 1980atmospheric variables. Preliminary results show that RaVE can produce parsimonious yet sensiblemodels. Future work will focus on devising criteria to select the best choice of hyperparametersand on methods to choose groups of spatially contiguous variables so as to aid interpretation.

Overcoming Data Constraints To Create Meaningful Ecological Models, Rebecca E. Lester, Peter G. Fairweather Jul 2010

Overcoming Data Constraints To Create Meaningful Ecological Models, Rebecca E. Lester, Peter G. Fairweather

International Congress on Environmental Modelling and Software

Many techniques used to model ecosystems cannot be meaningfully applied tolarge-scale ecological problems due to data constraints. Disparate collection methods, datatypes and incomplete data sets, or limited theoretical understanding mean that a wide rangeof modelling techniques used to model physical processes or for problems specific tospecies or populations cannot be used at an ecosystem scale. In developing an ecologicalresponse model for the Coorong, a South Australian hypersaline estuary, we combinedseveral flexible modelling approaches in a statistical framework to develop an approach wecall ‘ecosystem states’. This model uses simulated hydrodynamic conditions as input topredict one of a suite of states per …

Uncertainty Propagation Throughout An Integrated Water-Quality Model, Gabriele Freni, G. Mannina, G. Viviani Jul 2010

Uncertainty Propagation Throughout An Integrated Water-Quality Model, Gabriele Freni, G. Mannina, G. Viviani

International Congress on Environmental Modelling and Software

In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements in the different parts of the system. Uncertainty basically propagates throughout a chain of models in which simulation output from upstream models is transferred to the downstream ones as input. The overall uncertainty can differ from the simple sum of uncertainties generated in each …

Interacting Environmental Interfaces: Synchronization In Substance Exchange Between Environmental Interfaces Regarded As Biophysical Complex Systems, Dragutin T. Mihailović, M. Budincevic, D. Perisic, Igor Balaž, A. Firanj

International Congress on Environmental Modelling and Software

In modeling environmental interfaces regarded as biophysical complex systems, one of the main tasks is to create an operative interface with the external environment. The interface should provide a robust and prompt translation of the vast diversity of external physical and/or chemical changes into a set of signals that are understandable for a biophysical entity. Although the organization of any system is of crucial importance for its functioning, it should not be forgotten that in biophysical systems we deal with real-life problems where a number of other conditions must be satisfied in order to put the system to work.
