  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...

  • 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 ...

  • IberWQ: new simulation tool for 2D water quality modelling in rivers and shallow estuaries

    This paper presents a new freeware simulation tool (IberWQ) for 2D water quality modelling in rivers and non-stratified estuaries. The model computes the spatial and temporal evolution of several species and variables which are relevant for the evaluation of the environmental status of rivers and estuaries, including: Escherichia coli, dissolved oxygen, carbonaceous biochemical oxygen demand, ...

  • 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 ...

  • Comparison of autoregressive moving average and state space methods for monthly time series modelling of Labrador and South-East Quebec river flows

    Time series data such as monthly stream flows can be modelled using time series methods and then used to simulate or forecast flows for short term planning. Two methods of time series modelling were reviewed and compared: the well-known auto regressive moving average (ARMA) method and the state-space time-series (SSTS) method. ARMA has been used in hydrology to model and simulate flows with ...

  • 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 ...

  • A GIS-supported 3D approach for flood risk assessment of the Qu'Appelle River, Southern Saskatchewan

    This research introduces a hybrid approach for flood risk assessment through GIS. The developed approach is based on the integration of hydraulic simulation and GIS analysis, which allows spatial-based visualisation and prediction of flood disaster. In particular, the Hydraulic Engineering Center River Analysis System (HEC-RAS) model is employed to simulate multi-scenario flood cases within a ...

  • Open MI: linking models

    Traditionally sewers and rivers have been modelled separately using different software applications, with outputs from one model being fed into the other. However this does not fully represent the continuous interaction between the two modeled elements. Assessing the impact of sewerage discharges and overland flows from urban areas to watercourses and the subsequent effects of watercourse levels ...

  • Hydraulic modeling trends in 2003

    It is traditional as a New Year dawns to review the old year and draw some conclusions. Not to be left out, we asked a number of our industry experts to reflect on key developments in their area of specialism based on their observation of the activities and issues facing users around the world during 2003. We cover in turn each of our key areas – Collection Systems, Water Supply, River Systems, ...

  • 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.'
