  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • Canarina DESCAR software · water pollution dispersion model · algorithms 1

    8. Mathematical algorithms The application uses two different mathematical models: Buoyant jet model or Stratified model. The Buoyant model is ideal for pollutant discharges located in the proximities of the coast and in rivers, (using little depth). This model is based on a time-independent Gaussian equation which simulates the pollutant dispersion in the water. The Stratified ...

    8.1 Buoyant Jet model A type of mathematical model that has been developed for sumerged round buoyant jets is the length-scale model.  Discharges flows can be divided into different regimes each dominated by particular flow properties. Within each regime, the flow may be approximated with simple mathematical relations describing the simplified problem. A model that uses ...

  • 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 ...

  • The open real-time control (RTC)-Tools software framework for modeling RTC in water resources sytems

    Real-time control-Tools is a novel software framework for modeling real-time control and decision support in water resources systems. It integrates different control paradigms ranging from simple feedback control strategies with triggers, operating rules and controllers to advanced optimization-based approaches such as model predictive control (MPC). A key feature of the package is the modular ...

  • Wallingford Software’s solutions match flood report modeling requirements

    Water UK’s report on ‘Lessons learned from summer floods 2007’ highlights a need for better flood forecasting tools that Wallingford Software’s InfoWorks CS, RS and FloodWorks are perfectly aligned to meet. The water industry’s trade body set up a review after the devastating flooding that hit many parts of the country and overwhelmed the Mythe water treatment works in Gloucestershire, leaving ...

  • Spatial analysis of water quality using a combination of GIS and statistical software

    GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between ...

  • Canarina DESCAR software · marine pollution modeling · algorithms 7

    The stratification phenomena is the existence of two homogeneous water layers and separated by a thin thermocline layer. In such a case, we can say that the water is stratified. There is no exchange of pollutants through this pycnocline layer. In case we suppose that a pycnocline layer exists, we will be able to check the stability by means of the application of the following equation: ...

  • Graph-based approach for generating virtual water distribution systems in the software VIBe

    Application of virtual case studies (VCS) is a well established technique in environmental engineering to test measures, approaches, models or software. However, preparation of VCS for an infrastructure network is a tedious task. In literature, approaches can be found which generate very simplified VCS, which are only partly comparable with real world case studies. VCS which are more comparable ...

  • Methodology of functionality selection for water management software and examples of its application

    When developing new software products and adapting existing software, project leaders have to decide which functionalities to keep, adapt or develop. They have to consider that the cost of making errors during the specification phase is extremely high. In this paper a formalised approach is proposed that considers the main criteria for selecting new software functions. The application of this ...
