Linking Water Resource Network Models To An Open Data Management Platform, Phillipp Meier, Stephen Knox, Julien Harou
Linking Water Resource Network Models To An Open Data Management Platform, Phillipp Meier, Stephen Knox, Julien Harou
International Congress on Environmental Modelling and Software
The development of models for complex water resources systems frequently involves cus- tomising model formulations to fit unique institutional or physical problems. Linking existing model components is part of this process. As an alternative to pre-packaged models or building models based on components that comply to the same standard interface we present a model platform where network resource models (water, energy, transport, etc.) are linked to a data manager in a generic way. A modular architecture is achieved using a server for data storage. Clients connecting to the server, called Apps, provide import and export functions from and to various …
Defining The Spatiotemporal Surveillance Space For Alien Species' Invasions Using Approximate Bayesian Computation, Grant Hamilton, Rune Rasmussen, Jana Mullerova, Jan Pergl, Petr Pysek
Defining The Spatiotemporal Surveillance Space For Alien Species' Invasions Using Approximate Bayesian Computation, Grant Hamilton, Rune Rasmussen, Jana Mullerova, Jan Pergl, Petr Pysek
International Congress on Environmental Modelling and Software
The spatiotemporal dynamics of an alien species invasion across a real landscape are typically complex. While surveillance is an essential part of a management response, planning surveillance in space and time present a difficult challenge due to this complexity. We show here a method for determining the highest probability sites for occupancy across a landscape at an arbitrary point in the future, based on occupancy data from a single slice in time. We apply to the method to the invasion of Giant Hogweed, a serious weed in the Czech republic and throughout Europe.
The Data Processing Inequality And Environmental Model Prediction, Steven V. Weijs
The Data Processing Inequality And Environmental Model Prediction, Steven V. Weijs
International Congress on Environmental Modelling and Software
Prediction in environmental systems, such as hydrological streamflow prediction, is a challenging task. Although on a small scale, many of the physical processes are well described, accurate predictions of macroscopical (e.g. catchment scale) behavior with a bottom-up mechanistic approach often remains elusive. On the other hand, conceptual or purely statistical models fitted to data often perform surprisingly well for prediction. The data processing inequality, from the field of information theory, says that processing data with statistical procedures can only decrease, and not increase the information content of the data. This seems to contradict the intuition that our knowledge of physical …
Agent-Based Virtual Laboratories For A Novel Experimental Approach To Socio-Environmental Synthesis, Nicholas R. Magliocca, Mary Shelley, Mike Smorul
Agent-Based Virtual Laboratories For A Novel Experimental Approach To Socio-Environmental Synthesis, Nicholas R. Magliocca, Mary Shelley, Mike Smorul
International Congress on Environmental Modelling and Software
The number of agent-based modeling (ABM) applications within the socio-environmental context has exploded over the last decade. Most of these ABMs have been designed to deepen our understanding of the decision-making processes and human-environment interactions that lead to emergent community- and/or landscape-level outcomes in specific locations and contexts. While these 'case-based' ABMs have generally been successful in this aim - to which their popularity attests - little progress has been made through this case-based approach towards the ultimate goal of building coherent theory about the structure, dynamics, and sustainability of socio-environmental systems. Moving away from case-based ABMs, this paper will …
The Qmra Wiki: A Social Media Tool For Interdisciplinary And Interagency Collaboration For Quantitative Microbial Risk Assessment, Jade Mitchell, Mark H. Weir, Wietske Van Osch, Joan Rose
The Qmra Wiki: A Social Media Tool For Interdisciplinary And Interagency Collaboration For Quantitative Microbial Risk Assessment, Jade Mitchell, Mark H. Weir, Wietske Van Osch, Joan Rose
International Congress on Environmental Modelling and Software
This study presents a web-based social media system that supports quantitative microbial risk assessment (QMRA) and collaboration among interdisciplinary scientists and interagency stakeholders, namely the QMRA wiki. The QMRA wiki is intended to aid the development of risk assessments by providing a collection of raw data, models and calculators as well as a platform for exchange and cross-fertilization between the QMRA community and its stakeholders. The wiki is organized around the exploration of the QMRA paradigm including the following five components: hazard identification, dose-response assessment, exposure assessment, risk characterization and risk management. Additionally, the wiki houses a number of case …
