Development Of An Agent Based Coupled Economic And Hydrological Model Of The Deep Creek Watershed In British Columbia, Canada., John Janmaat, Markandu Anputhas Jul 2010

Development Of An Agent Based Coupled Economic And Hydrological Model Of The Deep Creek Watershed In British Columbia, Canada., John Janmaat, Markandu Anputhas

International Congress on Environmental Modelling and Software

Deep Creek is an important tributary of the Okanagan River system in Southern British Columbia. The creek drains a watershed with sediments deposited by multiple glacial events, resulting in a complex pattern of surface and groundwater connections throughout the basin. Further, the basin is experiencing changes in agricultural enterprises as well as population growth, and may be heavily impacted by climate change. The MIKE SHE integrated hydrological modeling system is being used to develop a model of the basin hydrology. The watershed is relatively small – with only a couple of hundred agricultural water users – lending itself to a …

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 …

Linking Wildfire Behaviour And Land-Use Modelling In Northern Mongolia, Christian Schweitzer, Joerg A. Priess Jul 2010

Linking Wildfire Behaviour And Land-Use Modelling In Northern Mongolia, Christian Schweitzer, Joerg A. Priess

International Congress on Environmental Modelling and Software

Numerous approaches of modelling wildfires have been published covering the regime itself, ignition probabilities, spreading patterns, risks and impacts. However, there is less research linking these validated mature approaches to dynamics of the terrestrial environment. We contribute to filling this gap via integrating a newly developed wildfire module into a land-use model, enabling us to include wildfire-impacts in dynamic simulations of socio-environmental systems. In the forest steppe region of Northern Mongolia, wildfires are a major concern, threatening grassland and forest areas, which are already under pressure of droughts, heavy grazing, (illegal) logging and increasing firewood demand. We employ the generic …

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 …

Qualitative Reasoning In Participatory Spatial Planning: The Use Of Osiris In The Yellow River Delta, P. J. F. M. Verweij, M. Van Eupen, J. Roos-Klein Lankhorst, W. Nieuwenhuizen

International Congress on Environmental Modelling and Software

Societies see the emergence of new governance concepts, based on the assumption that processes of planning and decision taking are no longer hierarchical but the product of complex interactions between governmental and nongovernmental organizations, and the general public (the model of ‘co-production of knowledge’; Callon, 1999). All involved are seeking to influence the collectively binding decisions that have consequences for their interests. To account for this changing governance and the increased number of stakeholders involved, decisions need to be assessed in an integrated context. This paper discusses the OSIRIS modeling environment for knowledge rule based reasoning on spatial information. The …

Choosing The Right Data Mining Technique: Classification Of Methods And Intelligent Recommendation, Karina Gibert, Miquel Sànchez-Marrè, Víctor Codina

International Congress on Environmental Modelling and Software

One of the most difficult tasks in the whole KDD process is to choose the right data mining technique, as the commercial software tools provide more and more possibilities together and the decision requires more and more expertise on the methodological point of view. Indeed, there are a lot of data mining techniques available for an environmental scientist wishing to discover some model from her/his data. This diversity can cause some troubles to the scientists who often have not a clear idea of what are the available methods, and moreover, frequently have doubts about the most suitable method to be …

Modelling The Complexity Of The Cropping Plan Decision-Making, J. Dury, F. Garcia, Arnaud Reynaud, O. Thérond, Jacques-Eric Bergez Jul 2010

Modelling The Complexity Of The Cropping Plan Decision-Making, J. Dury, F. Garcia, Arnaud Reynaud, O. Thérond, Jacques-Eric Bergez

International Congress on Environmental Modelling and Software

Every year farmers have to allocate their fields to different crops and crop management. These choices depend on multiple spatial and temporal factors, farmers’ strategy and risk behaviour. To support farmers in these complex decisions and efficiently allocate scarce resources, we studied cropping plan decisions in arable farms with the aim of simulating contextual changes. A deeper understanding of these processes at farm level is then a start to model and design flexible and environmental-friendly cropping systems. We propose a stepwise approach to study and formalize the complexity of the decision-making processes based on farmer’s interviews and on modelling approach …

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 Jul 2010

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.

Unexpected Side-Effects Of Winter Feeding: Learning From Mahalanobis Distances Factor Analysis In The Case Of Red-Crowned Cranes In Hokkaido, Japan, Yi-Liang Kuo Jul 2010

Unexpected Side-Effects Of Winter Feeding: Learning From Mahalanobis Distances Factor Analysis In The Case Of Red-Crowned Cranes In Hokkaido, Japan, Yi-Liang Kuo

International Congress on Environmental Modelling and Software

Winter feeding has become a critical approach to sustain animals in high latitude,but little literature has investigated possible side-effects in terms of ecological niches. Toexplore whether winter feeding might affect species distributions at regional scale, weemployed a novel spatial model, Mahalanobis Distances Factor Analysis, in the case ofRed-crowned Cranes (Grus japonensis) in Hokkaido, Japan. This model features betterprediction ability with more explicit ecological significance compared to conventionalmethods. Furthermore, particularly innovative is that axes are used to define ecologicalniches, with a minimal set of habitual variables to calculate habitat suitability in thealgorithm. In results, winter feeding seemed to considerably impact the …

Modelling Human Health By Levels Of Biological Organization, Wilfred R. Cuff, Clifford Clark, Paulette Richard, Venkata R S K Duvvuri

International Congress on Environmental Modelling and Software

The hierarchy of levels in the organization of matter, or the “hierarchy of life”, is a fundamentalconcept in biology, and biologists are used to thinking about their work asbeing at a particular level. Yet medicine, in both research and application, operatessomewhat independently of this concept, working almost exclusively at levels at or belowthe individual. Through the relatively-recent expansion of epidemiology, medicinedoes reach up to the level of the population - but medicine at higher levels of biologicalorganization remains under-developed. In this paper we review the biological idea ofhierarchy of life and explore what medical research and practice might look like …

Agent Based Modelling Of Caribou Environmental Interactions In The Canadian Arctic, Glen Lesins, Kaz Higuchi

International Congress on Environmental Modelling and Software

Agent or individual based modelling (IBM) is recognized as an important tool in biological modelling for simulating animal behaviour and interactions with the environment at the level of the individual while maintaining a collective perspective. The method allows rules to be programmed for the interactions between like and unlike species, responses to geographic factors and impacts from human activities. By emphasizing the development of appropriate rules for the individual, one can avoid imposing ad hoc assumptions concerning the population as a whole and instead allow emergent phenomena to unfold at the larger scale. Here we report on preliminary results using …
