Linking Governance Storylines With The D-Expanse Model To Explore The Power System Transition Pathways, 2014 University College London, UCL Energy Institute
Linking Governance Storylines With The D-Expanse Model To Explore The Power System Transition Pathways, Evelina Trutnevyte
International Congress on Environmental Modelling and Software
In 2008 United Kingdom adopted an ambitious target to reduce its greenhouse gas emissions by 80% by 2050, compared to the levels of 1990. This is an unprecedented challenge to the power sector and multiple energy-environment-economic modeling activities have been undertaken to inform the energy policy to deliver this low-carbon transition. The role of governance, choices and strategies of the key actors is increasingly acknowledged as an influential determinant of such transition, but traditional energy-environment-economic models can hardly analyze these aspects. This paper proposes a methodological approach to integrating the governance aspects into energy-environment-economic modeling. In the Realizing Transition Pathways …
Innovative Techniques For Quantitative Scenarios In Energy And Environmental Research: A Review, 2014 University College London, UCL Energy Institute
Innovative Techniques For Quantitative Scenarios In Energy And Environmental Research: A Review, Evelina Trutnevyte, Célene Guivarch
International Congress on Environmental Modelling and Software
Quantitative scenarios form the core of the future analysis in the energy, climate and other environment-related fields. A growing number of researchers worldwide start using innovative techniques for developing, analysing and choosing quantitative scenarios. Some of these techniques involve a large number of scenarios. Different rationales motivate these strands of research: better system understanding, uncertainty analysis, development of robust strategies, selection of a small set of scenarios, ability to link storylines with quantitative scenarios and other. These techniques are argued to provide both novel research insights and policy-relevant scenario exercises. A workshop, organised by UCL Energy Institute and Cired, on …
Qualitative Reasoning Models To Summarize And Compare Metapopulation Theories, 2014 University of Brasilia
Qualitative Reasoning Models To Summarize And Compare Metapopulation Theories, Isabella Gontijo Sá-Leão, Adriano Souza, Fernando Goulart, Paulo Salles
International Congress on Environmental Modelling and Software
A better understanding of population dynamics is needed in the face of accelerating changes and modifications of natural landscapes. Qualitative Reasoning based models have been considered as a tool for integration and exploration of conceptual knowledge in ecological systems and population dynamics. The objective of the present work is to develop a set of qualitative models in order to capture, formalize, summarize, and compare knowledge about different approaches to metapopulation theory. Three types of approaches were modelled: 1) the classical concepts developed by Levins; 2) Pulliam's view on source and sink populations; and 3) an integrated model of conservation, based …

International Congress on Environmental Modelling and Software
In recent years, innovative applications exploiting Linked Open Data (LOD) and the Semantic Web have opened up, combined and cross referenced high volumes of high-quality data and created tremendous new opportunities for data users as well as data providers. However, in order to serve the broadest community of users, technologies need to be developed that can manage large, constantly updated datasets and streams that are published in formats that were not designed with cross source linking in mind.
The EU-FP7 project SemaGrow aims to tackle this challenge by developing novel algorithms and methods for querying distributed triple stores, scalable and …
Testing Site-Specific Parameterizations Of Longwave Radiation Integrated In A Gis-Based Hydrological Model, 2014 University of Calabria
Testing Site-Specific Parameterizations Of Longwave Radiation Integrated In A Gis-Based Hydrological Model, Giuseppe Formetta, Olaf David, Riccardo Rigon
International Congress on Environmental Modelling and Software
Incoming (Rli) and outgoing (Rlo) longwave atmospheric radiation are very important components of the global radiation balance. They influence many hydrological processes such as evapotranspiration, soil-surface temperature, energy balance, and snowmelt. Field measures of Rli and Rlo are extremely rare except for a few sites and experimental watersheds. Many parameterization schemes were proposed in order to model Rli and Rlo by using easily available meteorological observations such as air temperature, relative humidity, incoming solar radiation and cloud cover.
In this work 10 methods of parameterizing clear sky radiation for the estimation of Rli and Rlo were integrated in the GIS …
Trade-Offs Of Biogas Production: Comparing Crop RoTations Under Different Climate Scenarios, 2014 University Bonn, Institute for Geodesy and Geoinformation, UFZ Helmholtz Centre for Environmental Research
Trade-Offs Of Biogas Production: Comparing Crop RoTations Under Different Climate Scenarios, Sven Lautenbach, Martin Volk, Micheal Strauch, Gerald Whittaker, Ralf Seppelt
International Congress on Environmental Modelling and Software
While increasing biofuel production is worldwide on the political agenda, concerns about the involved trade-offs are on the rise. However, the quantification of these trade-offs is typically based on the comparison of a limited number of plausible alternatives. We extended the analysis by applying a multi-objective genetic algorithm to estimate the set of Pareto optimal solutions which describe the trade-offs between the objectives. The Pareto solutions represent the (estimated) best options given the model and the specified control options. Our analysis studied food and fodder based crop rotations and two alternative biogas crop production schemes: a corn based production scheme …
An R Package For Implementing Multiple Evapotranspiration Formulations, 2014 University of Adelaide
An R Package For Implementing Multiple Evapotranspiration Formulations, Danlu Guo, Seth Westra, Holger R. Maier
International Congress on Environmental Modelling and Software
The use of multiple evapotranspiration (ET) models is critical for exploring the ambiguity in the representations of ET processes. Although ensemble ET models are increasingly used to address this ambiguity, practical issues include: 1) the diversity of process representations, which require different input data and constants; 2) the diversity of nomenclature, terminology and units used in the literature; and 3) the complexity of some formulations, requiring significant time for coding and leading to potential user errors. We describe an R package that estimates both actual and potential ET from 17 well-known formulations. Results are presented as summary text and plots, …
Using Locally Distributed Computing To Aid Water Quality Modelling, 2014 Occoquan Watershed Monitoring Laboratory (OWML), Virginia Tech
Using Locally Distributed Computing To Aid Water Quality Modelling, Saurav Kumar, Adil N. Godrej, Thomas J. Grizzard
International Congress on Environmental Modelling and Software
Watershed managers and other experts frequently use water quality models to manage and study watershed-waterbody systems. Many modern water quality models have become increasingly complex and require significant amount of computational resources to execute. This situation is further exacerbated by linked models, which require sequential execution of multiple models to simulate the entire system, along with data conversion to transfer data between the linked models. Many tasks, such as evaluations of the robustness of the modelling system through sensitivity analysis and applications of water quality models as a tool to aid decision-making, require multiple executions of water quality models and …
Characterizing Spatial Random Fields Through A Bayesian Inverse Modeling Framework And The High Throughput Computing Software - Htcondor, 2014 Brigham Young University
Characterizing Spatial Random Fields Through A Bayesian Inverse Modeling Framework And The High Throughput Computing Software - Htcondor, Carlos Osorio-Murillo, Daniel P. Ames, Heather Frystacky, Yoram Rubin
International Congress on Environmental Modelling and Software
Spatial Random Fields (SRFs) are used to characterize the behavior of variables which are difficult to measure everywhere. In the case of hydraulic conductivity used in groundwater models, heterogeneity can be modeled through structural parameters of the random fields – parameters that define the field’s spatial distribution. Characterization of these structural parameters using a stochastic inverse method requires the evaluation of thousands of potential realizations of the SRF which is a time consuming and challenging task – reducing the adoption of stochastic models. To address this issue, this paper presents the integration of high throughput computing using HTCondor with the …

Parallel Simulation Of Environmental Phenomena, Ralf Denzer, Peter Fitch, Ioannis N. Athanasiadis, Daniel P. Ames
International Congress on Environmental Modelling and Software
This paper discusses the current situation with respect to the parallel simulation of environmental phenomena. It is not based on a complete and thorough investigation of the state-of- the-art in this domain and is more driven by observations, experiences and ideas of the four contributors who see the need to raise awareness towards a more systematic approach in the future. It is meant as a discussion paper to stimulate a more systematic approach towards parallel simulation in the environmental domain. While examples are mostly taken from hydrology, they are only used as illustration of a generic situation. The section on …

Software Engineering For Scientific Application: Effort Report On The Community Land Model Within The Earth System Modeling Framework, Dali Wang, Yang Xu
International Congress on Environmental Modelling and Software
One key factor in the improved understanding of earth system science is the development and improvement of high fidelity models. Along with the deeper understanding of earth system processes, the software complexity of those modelling systems becomes a barrier for further rapid model improvements and validation. In this paper, we present our experience on better understanding of the community land model (CLM) within an earth system modeling framework. After the science and software background of CLM, we represent three groups of CLM software engineering practices, which aim to 1) better understand the software system for rapid software system development on …
Balancing Externalities And Industrial Costs In Air Quality Planning, 2014 University of Brescia, Italy
Balancing Externalities And Industrial Costs In Air Quality Planning, Claudio Carnevale, Giorgio Guariso, Enrico Pisoni, Marialuisa Volta
International Congress on Environmental Modelling and Software
When adopting regional plans aimed at improving air quality, environmental authorities are often faced with the relevant costs that the adoption of abatement measures implies. On the other hand, scientific literature has well documented damages due to air pollution impact on human health and ecosystems. This paper proposes a tool that allows balancing these two viewpoints by defining the efficient set of measures in a multi-objective perspective. Despite both external (health related) and internal (industrial/emission abatement related) costs can be measured in the same unit, namely money, it appears unacceptable to add them together as in a cost-benefit analysis, since …

Modelling The Impact Of Microbial Loop On Aquatic Food Webs, 2014 Jinan University - China, The University of Western Australia
Modelling The Impact Of Microbial Loop On Aquatic Food Webs, Yu Li, Liancong Luo, Vardit Makler-Pick, Emily K. Read, Matthew R. Hipsey
International Congress on Environmental Modelling and Software
In order to control algal blooms, it is necessary to better understand microbial interactions in aquatic ecosystems. Based on the traditional "Nutrients-Phytoplankton-Zooplankton-Detritus" (NPZD) model, the "Nutrients-Phytoplankton-Zooplankton-Detritus+Bacteria" (NPZD+B) model has been developed to investigate the impact of the microbial loop on aquatic food webs via nutrient cycling processes. The results of the NPZD+B model showed the positive impact of the microbial loop on phytoplankton growth, and illustrated the importance of "bottom-up" (resource) control of algal blooms in aquatic ecosstems. The study concludes that the microbial loop is an important model component for simulating water quality dynamics when nutrients are limited in …

International Congress on Environmental Modelling and Software
Stormwater runoff is one of the major transporters of fecal indicator bacteria (FIB) contaminant in the downstream areas. The development of models to predict FIB concentrations in stormwater runoff are important because it is impractical to monitor and analyze every different microorganism at all monitoring sites. Understanding the correlation of hydrological characteristics such as antecedent dry days (ADD), total rainfall (RAIN), average rainfall intensity (AVGINT), runoff duration (RUNDUR) and runoff volume (RUNVOL), is important in development of such models. In this study, the samples were collected from three different monitoring sites which include agriculture (Site 1); mixed catchment (site 2) …

Long-Term Numerical Simulation For Stability Within The River Mouth; Case Study: Rosetta Promontory, Egypt, Ali Masria, Abdelazim Negm, Moheb Iskander, Oliver C. Saavedra, M. A. Bek
International Congress on Environmental Modelling and Software
Estuaries are very sensitive and vulnerable to any interventions in coastal dynamics. Most of these inlets experience coastal problems such as severe erosion and accretion. Rosetta promontory, Egypt, is an example of such an environment. It suffers from coastline erosion and sedimentation inside the inlet. The shoaling of the inlet leads to hindering the navigation process of fishing boats, negative impacts to estuarine and salt marsh habitat and decreases the efficiency of the cross section to transferring the flood flow to the sea.
This paper aims to reach a new condition of stability of Rosetta Promontory by using coastal measures. …
