A Mathematical Model For Ghg From Sb-Mbr: Calibration By An Innovative Protocol, Giorgio Mannina, Alida Cosenza 2016 Universita di Palermo

A Mathematical Model For Ghg From Sb-Mbr: Calibration By An Innovative Protocol, Giorgio Mannina, Alida Cosenza

International Congress on Environmental Modelling and Software

A mathematical model to quantify greenhouse gases (GHG) (carbon dioxide, CO2 and nitrous oxide, N2O) for a membrane bioreactor (MBR) is presented. The model has been applied to a pilot plant with a pre-denitrification MBR scheme. The pilot plant was cyclically filled with real saline wastewater according to the fill-draw-batch operation. The model was calibrated by adopting a specific protocol based on extensive field dataset. Standardised Regression Coefficient (SRC) method was adopted to select the most influential model factors to be calibrated. Results related to SRC method show that among the important model factors a key role ...

Cool Farm Tool (Cft) Water: Novel Tool For Water Resource Assessment On Field Scale, Benjamin Kayatz, Gabriele Baroni, Benjamin Kuster, Stefan Lüdtke, Daniella Malin, Richard Heathcote, Carl Von Tonder, Martin Wattenbach

International Congress on Environmental Modelling and Software

At the global scale over 70 % of all fresh water used is consumed by the agricultural sector. For this reason a sustainable water management at the basin level often requires the assessment of water that is used for crop production. In this context, the characterization of green and blue water footprint showed to be a useful and efficient approach to support analysis and decisions.

However determining the water footprint is cumbersome and often linked to additional data acquisition efforts. Furthermore the water footprint is often not revealing the basin impact of crop production. To overcome these limitations we developed CFTwater ...

Anthony Castronova

Computer models are widely used in hydrology and water resources management. A large variety of models exist, each tailored to address specific challenges related to hydrologic science and water resources management. When scientists and engineers apply one of these models to address a specific question, they must devote significant effort to set up, calibrate, and evaluate that model instance built for some place and time. In many cases, there is a benefit to sharing these computer models and associated datasets with the broader scientific community. Core to model reuse in any context is metadata describing the model. A standardized metadata ...

A Simulation Platform To Assess Forest Landscape Resilience, Werner Rammer, Rupert Seidl 2016 Institute of Silviculture, Department of Forest- and Soil Sciences, University of Natural Resources and Life Sciences (BOKU)

A Simulation Platform To Assess Forest Landscape Resilience, Werner Rammer, Rupert Seidl

International Congress on Environmental Modelling and Software

Forest ecosystems suffer increasingly from pressures such as anthropogenic climatic change, while at the same time being subject to an increasing societal demand for ecosystem services. In addition to direct climate effects on tree growth and regeneration recent research suggests that climate-induced changes in disturbance regimes will likely increase the volatility of future forest trajectories. Addressing these challenges requires a coupled human and natural systems perspective, as most of Europe’s forests are heavily influenced by management, and forests are a crucial component in the emerging bioeconomy. Methodologically, assessments of the long-term socio-ecological resilience of forest ecosystems require approaches that ...

Bayesian Estimation Of Source Term Of Atmospheric Radiation Release With Interval Prior, O. Tichý, V. Šmídl, R. Hofman 2016 Institute of Information Theory and Automation, Czech Academy of Sciences

Bayesian Estimation Of Source Term Of Atmospheric Radiation Release With Interval Prior, O. Tichý, V. Šmídl, R. Hofman

International Congress on Environmental Modelling and Software

Detection of release of an atmospheric pollutant is a problem of interest in environmental sciences. We are concerned with estimation of unknown source term of the release. Formally, the problem is formulated as a linear model where measurements are explained using source-receptor- sensitivity matrix obtained from atmospheric transport model and source term vector which has to be estimated. Specifically, we estimate the release of radioactivity from measurements of gamma dose rate (GDR). The problem of isolation of activity of individual nuclides is poorly conditioned. We propose a probabilistic model with the prior information on intervals of nuclide ratios. The model ...

Advanced Clustering To Integrate Spatial Socio-Ecological Components In Decision-Making: A Case Study On Sustainable Agriculture, Stéphane Bourrelly, Antonino Marvuglia, Ian Vázquez-Rowe

International Congress on Environmental Modelling and Software

Accounting for the direct and indirect role of ecosystem services (ES) in supporting human activities is a priority among governmental targets to develop strategies of impact mitigation with the mutual effect of increasing human well-being. Although a great deal of research is currently being done on ES assessment, the volume of available data and the complexity of mechanisms make the decision-making process difficult. We highlight the strengths of unsupervised clustering for handling geographic multidimensional datasets. We explain why the outputs, both in qualitative and quantitative form, can help stakeholders to conceive sustainable policies. At the same time, we point out ...

International Congress on Environmental Modelling and Software

One of the aims of the REGARD project is to evaluate the influence of human activities in the modelling of water resources in the South-West of France, at the scale of the Garonne Watershed (~55 000 km2). Since 2009 the French government introduced a new regulation of agricultural water withdrawals, to avoid regular crisis due to water resources issues.Our approach consists in accounting for small farm dams in the Safran-Isba-Modcou (SIM) model and to evaluate their impact on river discharges. Several scenarios with different volume capacities, filling catchment sizes and filling periods were tested to assess how the ...

International Congress on Environmental Modelling and Software

This study compared two types of (offline vs. online) bias correction models applied to correct the mismatch between the predicted daily averaged PM10 concentration by the deterministic air quality forecasting system WRF-EURAD and the measured concentration at the air quality monitoring station in Porto, Portugal. The WRF-EURAD is a Eulerian system consisting of a Weather Research Forecasting (WRF) model and a European Air Pollution Dispersion (EURAD) model. Both bias correction models were linear statistical models developed with the same set of input variables. The major difference between the online or the offline models is the adaptiveness. While the coefficients ...


Modelling Small Agricultural Dams Dynamics Into The Maelia Multi-Agent Platform, Romain Lardy, Camille Truche, Olivier Therond 2016 ARVALIS - Institut du végétal, UMR 1248 AGIR, INRA-INPT

Modelling Small Agricultural Dams Dynamics Into The Maelia Multi-Agent Platform, Romain Lardy, Camille Truche, Olivier Therond

International Congress on Environmental Modelling and Software

In France, during the three last decades farmers built numerous small dams to have alternative resources for irrigation. In water deficit situations, one major question of the debate is the cumulative effect at watershed and river basin levels of small water dams on stream flows during the low flow period. This paper presents a new modelling framework to simulate hydrology and cumulative effect of small agricultural dams at river basin level that was implemented in the multi-agent modelling and simulation MAELIA platform. This modelling framework is based on the distinction of four types of small dams: connected to groundwater; disconnected ...

The coastal area has naturally attractive to population and industry due to its convenient geographical location and abundant resources. While the coastal area provides geographical advantages and resources for urban development, it also experiencing a dramatically growing vulnerability to natural hazards. For coastal mega-cities like Shanghai, typhoon storm surge presents a significant threat to both infrastructure and populations with relatively high vulnerability. Another fact about Shanghai coastal area is that the reclamation land has grown substantially due to the huge demand of land for further urban development. On the one hand, the reclamation land can alleviate the continuous growth of ...


A Multi-Disciplinary Procedure To Ascertain Biofilm Formation In Drinking Water Pipes, Eva Ramos-Martinez, Manuel Herrera, Joaquín Izquierdo, Rafael Pérez-García 2016 FluIng-IMM Universitat Politècnica de València

A Multi-Disciplinary Procedure To Ascertain Biofilm Formation In Drinking Water Pipes, Eva Ramos-Martinez, Manuel Herrera, Joaquín Izquierdo, Rafael Pérez-García

International Congress on Environmental Modelling and Software

Biofilm development in drinking water distribution systems (DWDSs) is a real problem negatively affecting service and water quality, and, thus, the satisfaction of the final consumers. It is the direct and indirect responsible for many of the DWDSs’ problems, and a lot of resources are invested to mitigate its effects. Addressing this problem has been a concern of researchers and DWDS managers for years. However, it is only recently that both technology and data have been available to support the new approach presented in this work. Our proposal is based on the combination of various existing data sets from similar ...

International Congress on Environmental Modelling and Software

Free-range and common-grazing ruminants play a major role in the functioning and the provision of ecosystem services by agro- and silvo-pastoral ecosystems in sub-Saharan Africa. To assess how landscape structure affects the nature of environment-herd-services interactions, this paper describes a Multi-Agent System (MAS) that simulates daily herd movements in a dynamic environment. The model is used to study how the overall productivity of an agricultural territory is affected by the spatial organization of its different landscape units. The originality of this model lies in fine representation, in hourly time steps, of a herd’s movements and activities over the seasons ...

A New Gpr Image Analysis Proposal Based On A Multi-Agent Approach And Properties Of Groups – Towards Automatic Interpretations, David Ayala-Cabreraa, Manuel Herrera, Joaquin Izquierdo, Rafael Pérez-García, Olivier Piller

International Congress on Environmental Modelling and Software

This paper proposes a new methodology to analyze images from subsoil surveys obtained by using ground penetrating radar (GPR) as a non-destructive method. The aim is to advance towards automatic GPR image interpretations. The main idea is to promote the inclusion of these non- destructive technologies as support in technical management in large-scale systems such as water distribution systems (WDSs). The methodology proposed in this paper uses pre-processing techniques based on a multi-agent approach and analysis of the properties of the obtained groups. In addition, a first classification (via perceptron) of the selected property in the groups is performed. The ...

Targeting Rebates In The Water-Energy Nexus, Alvar Escriva-Bou, Manuel Pulido-Velazquez, Jay R. Lund

International Congress on Environmental Modelling and Software

Water conservation is often the most cost effective source of additional water supply for water stressed regions to maintain supply reliability with increasing population and/or demands, or shorter-term droughts. In previous research we demonstrated how including energy savings of conserved water can increase willingness to adopt conservation measures, at the same time that increases energy and GHG emissions savings. But the capacity to save water, energy and GHG emissions depends fundamentally in the economic benefits for customers and utilities.

Utilities have traditionally used rebates, subsidies or incentives to enhance water conservation. But the economic benefits originated by these rebates ...


Actor-Based System Dynamics Modelling Of Win-Win Climate Mitigation Options, Dmitry V. Kovalevsky, Klaus Hasselmann 2016 Nansen International Environmental and Remote Sensing Centre (NIERSC), Saint Petersburg State University

Actor-Based System Dynamics Modelling Of Win-Win Climate Mitigation Options, Dmitry V. Kovalevsky, Klaus Hasselmann

International Congress on Environmental Modelling and Software

The actor-based system dynamics approach to Integrated Assessment modelling (IAM), seen as further development of ‘traditional’ system dynamics economic modelling, however with a stronger emphasis on describing the decision making of key aggregate economics actors, is a promising methodology for developing the comprehensive IAMs of next generations. The present paper is focused on application of actor-based system dynamics models to identification and assessment of win-win opportunities of climate mitigation policies. Modelling results outlined suggest that in a multi-country world properly designed climate mitigation policies can unite rather than divide different nations, therefore putting under question the ‘juggernaut’ of much discussed ...

Rural Livelihood, Biodiversity And Carbon Stock In Vietnam Mountains: Agent-Based Modeling To Anticipate Trade-Offs, Quang Bao Le

International Congress on Environmental Modelling and Software

Assessment of future multiple ecosystem services driven by alternative land-use policies is useful for supporting decisions about what and where to invest for the best overall environmental and developmental outcomes. The task faces a great challenge due to the inherent complexity of human- landscape systems and trade-offs between rural livelihood improvement, biodiversity conservation and carbon sequestration. Agent-based system models have been recognized to be well suited to simulate the co-evolutions of the community and landscape systems in response to policy interventions. The study applies the Land Use Dynamics Simulator (LUDAS) framework to a mountain watershed in central Vietnam for anticipating ...
