A Proposed Approach To The Development Of Federated Model Sets, Kenneth M. Bryden
International Congress on Environmental Modelling and Software
Integrated modelling is a critical environmental modelling tool that brings together sets of models and data to describe the impacts of various management practices and choices within the environment. Although each model may (or may not) run on separate hardware, typically these model sets are organized together as a large integrated, centralized model. These integrated models share a single conceptual schema and semantic framework. Additionally, information flow and convergence of boundary conditions between the models are generally built on a fixed framework. Although this is a logical approach that has proven to be effective, it has several limitations. The models …

Kernel Density Independence Sampling Based Monte Carlo Scheme (Kismcs) For Inverse Hydrological Modeling, Mojtaba Shafiei, Shervan Gharari, Saket Pande, Sandjai Bhulai
International Congress on Environmental Modelling and Software
Posterior sampling methods are increasingly being used to describe parameter and model predictive uncertainty in hydrologic modelling. This paper proposes an alternative to random walk chains (such as DREAM-zs). We propose a sampler based on independence chains with an embedded feature of standardized importance weights based on Kernel density estimates. A Markov Chain Monte Carlo sampling algorithm is proposed with Metropolis-Hastings (M-H) updates using an independence sampler. The independence sampler ensures that candidate observations are drawn independently of the current state of a chain, thereby ensuring efficient exploration of the target distribution. The M-H acceptance-rejection criterion is used to sample …

Accounting For Groups Of Animals In Qmra Of Recreational Waters, Richard W. Muirhead, Vanessa M. Cave
International Congress on Environmental Modelling and Software
The development of QMRA for recreational waters often involves assessing the inputs from multiple sources, including human sewage, agricultural sources and wild animals. The concentrations of microorganisms in faeces from individual animals are highly variable leading to a broad spectrum of risk. When modelling the load of faecal microbes from a group of animals, based on data from individuals, the group distribution must be correctly accounted for. A further complication to QMRA is that pathogen concentrations in faeces have a high proportion of non-detects making them difficult to model using standard mathematical distributions. Moreover, when only limited concentration data are …

International Congress on Environmental Modelling and Software
Many point-based models have been designed to simulate hydrology, gas flux, nutrient dynamics, and/or plant growth processes at a single point on the landscape. However, these environmental processes are known to be spatially variable. Simulations at different spatial locations therefore require adjustment of model input parameters to reflect specific conditions at each location. Increased availability of geospatial data sets, including remote sensing images, land cover maps, digital soil surveys, crop yield maps, and vehicle-based plant or soil maps, can support spatial model parameterization efforts. However, tools are needed for processing geospatial data layers and interfacing the data with the simulation …

International Congress on Environmental Modelling and Software
The objective of this research is to develop and to model an indicator of social vulnerability as part of a multidimensional, multivariable and non linear process. Social vulnerability can be considered as a complex system, in which many relationships in society and environment can be described by considering individual and structural factors. Numerous studies provide tools to analyze and revise social systems but these tools were developed generalizing and overviewing the relationship among many intermediate realities, for another type of systems, more formalized and conceptualized. Social systems do not have this classical formalization. The development of the SocIaL Vulnerability I …

International Congress on Environmental Modelling and Software
Headwater streams are the most abundant portion of the river network but the least monitored. As such, we have a limited understanding of headwater stream behaviours and how they are influenced by catchment properties such as topography, geology, and vegetation. Given the lack of runoff monitoring within headwater streams, improving an understanding of how catchment properties influence hydrologic behaviour is necessary for transferring information from instrumented areas to ungauged sites. We utilize this concept to understand physical controls on similarities and differences in hydrologic behaviour for five adjacent sub-catchments located in the Tenderfoot Creek Experimental Forest in central Montana with …

Estimating The Benefits Of Early Warning Systems In Reducing Urban Flood Risk To People: A Spatially Explicit Bayesian Model., Stefano Balbi, Ferdinando Villa, Vahid Mojthaed, Carlo Giupponi
International Congress on Environmental Modelling and Software
Flood risk assessment usually focuses on damages to material objects (indirect tangible costs) and downplays the broader socio-economic aspects of flood-prone systems. Such aspects are crucial for an accurate assessment of risk to human receptors and of the benefits of non-structural measures. For example, an early warning system (EWS) that reduces the amount of direct tangible costs only partially could: (i) save lives (direct intangible costs); (ii) help avoid long-lasting trauma (indirect intangible costs); (iii) prevent post-disaster evacuation costs (indirect tangible costs). We present a methodology to assess flood risk to people, which integrates people's vulnerability and ability to cushion …

Managing the water quality in an urban environment is extremely challenging. While it flows, the water picks up pollutants such as lawn care chemicals, oil, and pet waste bacteria. In fact, topography plays a factor in where water runoff goes. However, there are many other factors, such as urban density, impermeable surface coverage, weather events and tidal patterns which all have the potential to impact not only the final destination of a particular pollutant but also the rate of travel along the route. In this paper, we propose a system, named AMADEUS (Azure Marketplace of Applications for Diverse Environmental Use …

According to EEA (European Environmental Agency), flood is the most dangerous natural hazard in Europe in terms of economic losses. The KULTURisk Project (EU FP7) has developed a novel methodology for evaluating the integrated benefits of risk prevention of water related natural hazards: SERRA (i.e. Socio-Economic Regional Risk Assessment). The proposed methodology enhances the traditional flood risk assessment. Several case studies across Europe allowed for the consolidation, validation, and refinement of SERRA. This paper presents the results of its application to assess the benefits derived from the installation of an Early Warning System in Vipacco river basin in Friuli Venezia …

Investigating Parameter Sensitivity For Management In Snow-Driven Watersheds, Elizabeth Houle, Joseph Kasprzyk
International Congress on Environmental Modelling and Software
Recent projections of environmental change have shown possible variation to temperature and precipitation patterns due to climate change. In snowmelt-dominated watersheds, adapting to such environmental changes requires a detailed understanding of hydrological processes in addition to historical snow cover and streamflow data. Snow models are often incorporated as an additional component of hydrological modeling studies that inform research and operations management. However, previous research and parameter estimation approaches using snow models assume that parameters have a single optimal value and that each parameter is sensitive. This paper demonstrates that an improved understanding of snow model parameter sensitivity can aid in …

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 …
