    International Journal of Environment and Pollution (IJEP)

    The international Journal of Environment and Pollution is a refereed journal providing an international forum for the field of environment and pollution. One of three key journals (along with The International Journal of Environmental Technology and Management and and The International Journal of Global Environmental Issues) which together offer ...

  • International Journal of Sustainable Economy (IJSE)

    Globalisation, internationalisation, technological progress, growth of human capital, technology transfer, care for natural environment and integration processes increasingly influence economic growth and development of human societies. A very special characteristic of societal development, from economic theory point of view, is so-called ...

  • 3-D frequency-domain seismic wave modelling in heterogeneous, anisotropic media using a Gaussian quadrature grid approach

    We present an extension of the 3-D spectral element method (SEM), called the Gaussian quadrature grid (GQG) approach, to simulate in the frequency-domain seismic waves in 3-D heterogeneous anisotropic media involving a complex free-surface topography and/or sub-surface geometry. It differs from the conventional SEM in two ways. The first is the ...

  • Ecological Indicators

    The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal will provide a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative ...

  • Explicit expressions and numerical calculations for the Fréchet and second derivatives in 2.5D Helmholtz equation inversion

    In order to perform resistivity imaging, seismic waveform tomography or sensitivity analysis of geophysical data, the Fréchet derivatives, and even the second derivatives of the data with respect to the model parameters, may be required. We develop a practical method to compute the relevant derivatives for 2.5D resistivity and 2.5D ...

  • Composite boundary‐valued solution of the 2.5-D Green’s function for arbitrary acoustic media

    Theoretically, the Green’s function can be used to calculate the wavefield response of a specified source and the Fréchet derivative with respect to the model parameters for crosshole seismic full‐waveform inversion. In this paper, we apply the finite‐element method to numerically compute the 2.5-D Green’s function for an arbitrary acoustic medium ...

  • Explicit expressions for the Fréchet derivatives in 3D anisotropic resistivity inversion

    We have developed explicit expressions for the Fréchet derivatives or sensitivity functions in resistivity imaging of a heterogeneous and fully anisotropic earth. The formulation involves the Green’s functions and their gradients, and it is developed from a formal perturbation analysis and by means of a numerical (finite-element) method. A ...

  • Environmental Modeling & Assessment

    There is a growing interest in the field of modeling and quantitative assessment of environmental problems. For some years now results of environmental models and assessment analyses have been influencing environmental regulation and policies at local, national and international levels. Therefore the need to understand both the power and ...

  • Ecological Modelling

    The journal is concerned with the use of mathematical models and systems analysis for the description of ecosystems and for the control of environmental pollution and management of resources. It combines mathematical modelling, systems analysis, thermodynamics and computer techniques with ecology and management of the environment and its natural ...

  • Crosshole seismic inversion with normalized full‐waveform amplitude data

    We investigate a simple scheme for full‐waveform amplitude spectrum inversion of crosshole seismic data with an unknown source wavelet. The method is based on our 2D/2.5D finite‐element method of acoustic‐wave modeling. The normalized amplitude data, defined as the spectral ratio of the original trace amplitude to the average amplitude for the ...

  • 2.5D modelling of elastic waves in transversely isotropic media using the spectral element method

    The spectral-element method provides an accurate alternative to the finite-element method for modelling elastic waves in anisotropic media. With the aim of reducing the high computational overheads of 3D modelling, we have implemented 2.5D spectral-element modelling of elastic waves, initially for vertically transversely isotropic media, and then ...

  • Environmental Fluid Mechanics

    Environmental Fluid Mechanics is an interdisciplinary journal devoted to the publication of basic and applied studies broadly relating to natural fluid systems, particularly as agents for the transport and dispersion of environmental contamination. Understanding transport and dispersion processes in natural fluid flows, from the microscale to the ...

  • International Journal of Ecological Economics and Statistics

    The main aim of the International Journal of Ecological Economics and Statistics (IJEES) publishes refereed, well-written original research articles, and studies that describe the latest research and developments in ecological economics and ecological statistics. IJEES is an interdisciplinary research journal in the area of environmental economics ...

  • Environmental Modelling & Software

    Environmental Modelling & Software publishes research articles, review papers and short communications on recent advances in environmental modelling and software. It seeks presentation of generic techniques and issues which apply across or integrate a range of disciplines, as well as model applications in specific sectors of the environment, as ...
