BREEZE is the market-leading air dispersion modeling software used by environmental professionals around the world Receptors are specific locations, set up in air quality dispersion models, where ambient concentration estimates or deposition values are needed. ...
While most air dispersion modeling is conducted using meteorological data from recent past years and historical or projected emissions data, models can also be used with real-time or short-term forecast meteorological and emissions data to estimate impacts at the present time and in the near future. In order to develop these custom real-time air dispersion modeling and forecasting systems, ...
An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a ...
This paper has improved on Khan et al.'s established model (see Khan et al. (2009) ‘Analyzing complex behavior of hydrological systems through a system dynamics approach’, Environmental Modeling & Software 24, 1363–1372) by adding water production functions for three main crops (winter wheat, ...
Multimedia environmental fate models are valuable tools for investigating potential changes associated with global climate change, particularly because thermodynamic forcing on partitioning behavior as well as diffusive and nondiffusive exchange processes are implicitly considered. Similarly, food‐web bioaccumulation models are capable of integrating the net effect of changes associated with ...
In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements ...
Modeling of multimedia environmental issues is extremely complex due to the intricacy of the systems with the consideration of many factors. In this study, an improved environmental multimedia modeling is developed and a number of testing problems related to it are examined and compared with each other with standard numerical and analytical methodologies. The results indicate the flux output of ...
Surface-based monitoring programs provide the foundation for associating air pollution and causal effects in human health studies, and they support the development of air quality standards and the preparation of emission reduction strategies. While surface-oriented networks remain a key tool for addressing traditional single pollutant human exposure challenges, these networks in isolation are not ...
This study proposes a robust optimisation capacity expansion planning model that yields a less sensitive solution due to variations in model parameters such as demand and fuel prices. By adjusting the penalty parameters, the model can accommodate the decision maker's risk aversion and yield a solution based upon it. The proposed model is then applied to Ontario Power Generation, the largest power ...
Abstract Measurements of Nitrous Acid (HONO) mixing ratios and other compounds were made in the north-east periphery of the town of Ashdod (south of Tel Aviv, Israel) during two campaigns in the autumn of 2004 and the summer of 2005. This work was part of a bilateral Italian-Israeli cooperation on environmental technologies, project “Modeling system for urban air pollution”. Statistical analysis ...
Abstract For over two decades, the Industrial Source Complex (ISC) dispersion model has been the primary model used to predict ambient air impacts from stationary sources. Recent advances in dispersion modeling theory have resulted in the creation of a new type of modeling algorithm referred to as the American Meteorological Society/U.S. Environmental Protection Agency Regulatory Modeling System ...
Overview Environmental policy is in transition. Many observers believe that the existing regulatory system, though it has accomplished great improvements in environmental quality, is approaching the limits of its effective ness. Government regulators and policy analysts are seeking better ways to address the many issues, like non-point source pollution, that remain largely unregulated. Most ...
' Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most ...
