  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • Arctic Polar Research - A Global Responsibility

    Due to climate change and geopolitical trends, the Polar Regions (particularly the Arctic) are increasingly becoming the focus of scientific, political, and economic interests. Much of the global climate is driven by forces that originate in the Arctic. The Arctic sea ice is receding faster than climate models have predicted, and the movement of freshwater into and around the Arctic plays an ...

  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Water Resources Management and Modeling

    Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the ...

  • Rold Model Water Recycling Program

    ABSTRACTThe Viejas Band of Kumeyaay Indians, a federally recognized tribe, vested with authority by the U.S. Environmental Protection Agency (USEPA), form the Tribal Government to regulate all activities concerning water quality issues within the reservation boundaries. The Reservation has 400 non-transient residents and an average of 5,000 transient residents. The transient population visits the ...

  • Hydraulic modeling and water quality monitoring

    Untitled Document The 2004 IMTech conference held in Baltimore, Maryland, April 18-20, attracted hundreds of water professionals interested in the application of IT solutions in water supply and distribution ...

  • Integrated modeling on water resource management

    World is facing a water crisis and increasing in recent years. It is necessary to understand the water system from source to sink and about 10% of total annual runoff is being used. Agriculture is found largest direct user of water. Asia is consuming about 23%, highest percentage of available water resources. Various steps for efficient water resources management are discussed. Decision support ...


  • Modelling the urban water system of Alexandria using the Aquacycle model

    As in other cities in Egypt, water demand in the metropolitan area of Alexandria is rapidly increasing over time, as a result of urban expansion, amelioration of living standards and industrial development. As the River Nile is the main source of freshwater supply, concerns arise regarding a potential reduction in Alexandria's allocation quota, which could affect population growth at the ...

  • Combining multimedia models with integrated urban water system models for micropollutants

    Integrated urban water system (IUWS) modeling aims at assessing the quality of the surface water receiving the urban emissions through sewage treatment plants, combined sewer overflows (CSOs) and stormwater drainage systems. However, some micropollutants tend to appear in more than one environmental medium (air, water, sediment, soil, groundwater, etc.). In this work, a multimedia fate and ...

  • On the effect of scaling conceptual model complexity on stochastic response for water quality modeling

    This paper extends previous work comparing the response of water quality models under uncertainty. A new model, the River Water Quality Model no. 1 (RWQM1), is compared to the previous work of two commonly used water quality models. Additionally, the effect of conceptual model scaling within a single modelling framework, as allowed by RWQM1, is explored under uncertainty. Model predictions are ...

  • Water balance modelling of alternate water sources at the household scale

    Alternate water sources are being implemented in urban areas to augment scheme water supplied by a water utility to homes. These sources include residential wells, rainwater tanks and greywater systems. Greater water efficiency can be achieved when these systems are designed to match a water source to a given demand based on both water quantity and quality parameters. In this way the use of an ...

  • Application of the urban water use model for urban water use management purposes

    The aim of this work is to present an application of the urban water use (UWU) model, which is a support decision tool to define the best group of efficient water use measures for UWU management purposes. Therefore, the UWU was developed under integrated urban water management (IUWM) and strategic planning principles to promote a systemic approach for decision taking. The IUWM considers the ...

  • Urban-Water Harmony model to evaluate the urban water management

    Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The ...
