  • Recognition of karst structure using refraction tomography

    The results of location of karst wells and probable hydraulic connections between them in limestone massif using the refraction tomography are presented. Seismic modeling was based on refraction horizon recognition in the first stage and tomographic processing of P-wave and S-wave velocity changes in the second one. The studies were carried out on the terrain neighboring to the wall of abandoned ...

  • Software is the soul of a tractor

    'Each year software is playing an increasingly important role, also when it comes to tractors. It is no longer possible to count the number of lines of code, as a single hydraulic valve from an outside supplier can contain as much code as an early HiTech tractor. Advanced software also allows a tractor’s functions to be altered after production. Software development, like all other tractor ...

  • 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, ...

  • Hydraulic modeling experience in consulting practice

    Hydraulic modeling experience in consulting practice: Comprehensive Hydraulic Modeling software applications in water and sanitation engineering consultancy practice are a must and are very much essential to simplify several single line or small tree distribution iteration processes used in the olden days. Several Hydraulic models are available for Hydrology, water supply, storm ...


  • A combined hydraulic and biological SBR model

    A sequencing batch reactor (SBR) model was developed consisting of six continuous stirred tank reactors which describe the hydraulic flow patterns occurring in different SBR phases. The model was developed using the results of computational fluid dynamics (CFD) simulation studies of an SBR reactor under a selection of dynamic operational phases. Based on the CFD results, the model structure was ...

    Comprehensive Hydraulic Modeling software applications in water and sanitation engineering consultancy practice are a must and are very much essential to simplify several single line or small tree distribution iteration processes used in the olden days. Several Hydraulic models are available for Hydrology, water supply, storm water management and water shed management. For large area ...


  • Uncertainty in design flood profiles derived by hydraulic modelling

    The scientific literature has widely shown that hydraulic modelling is affected by many sources of uncertainty (e.g. model structure, input data, model parameters). However, when hydraulic models are used for engineering purposes (e.g. flood defense design), there is still a tendency to make a deterministic use of them. More specifically, the prediction of flood design profiles is often based ...

  • Mathematical modelling of a hydraulic controller for PRV flow modulation

    This paper describes the development of mathematical models, which represent static and dynamic properties of the AQUAI-MOD® hydraulic controller coupled with a standard pressure reducing valve (PRV) as well as a new experimental set-up for testing the controller and calibrating and validating the models. The purpose of the AQUAI-MOD® controller is to modulate the PRV outlet pressure according to ...

  • Hydraulic Modelling in the Middle East and North Africa

    Water is under pressure in the Middle East and North Africa, a region which houses 4% of the world’s population but possesses only 1.4% of global water resources. A naturally scarce resource at the best of times faces increasing demand from a growing population with high expectations of water quality, supply and treatment. At the same time, the price of water fails to reflect the true cost of ...

  • Integrating GIS and Hydraulic Modelling in Urban and Rural Applications

    Overview In the UK, numerical Hydraulic Modelling of the urban environment, water networks and rivers plays a vital role in providing the UK Water Industry with solutions for protecting the environment, meeting UK Government and European Regulations, meeting OPEX and CAPEX business targets, and improving the efficiency of Water Companies in managing their assets. Similarly, the UK water ...

  • Using InfoNet to build InfoWorks CS hydraulic models

    Water utilities are now using MWH Soft’s InfoNet database and network management solution to monitor data, which has in turn enabled digital models of these networks to be created in a more efficient way. Many countries are still developing modeling standards, and management tools are either basic or non-existent, so these challenges have to be faced when building models to ensure they are ...

  • Using GIS to Build Hydraulic Models Faster

    The use of hydraulic models, already widespread, continues to grow rapidly.  Modeling is used increasingly all around the world to address planning and operational issues in water supply networks, collection systems, and river management. Much of this growth results from the rapid advances in the capabilities of the best of the hydraulic modeling software solutions, which constantly improve ...

  • Recent Papers on Applied Hydraulics

    Reactor hydraulics is one of the key factors for plant performance and plant control. The residence time distribution is a good but limited indicator of reactor hydraulics. A more detailed view is obtained by direct observations within the reactor. Two different techniques (conservative tracer, reactive tracer) are discussed to ...

  • Hydraulics-based estuarine management

    Hydraulics-based estuarine management is one of the most promising estuarine management methods. It is achieved by varying freshwater inflows into an estuary such that the ecosystem or environmental conditions within the estuary become most desirable. The assumption is that freshwater inflows to an estuary can be controlled by regulating upstream reservoir releases. This article summarises recent ...

  • Experimental investigation of leak hydraulics

    In recent decades the hydraulics of leaks, i.e. the definition of the relationships linking the hydraulic quantities in pipes with leaks, has received increasing attention. On the one hand, the definition of the relationship between the leak outflow and the relevant parameters – e.g. the leak area and shape, the pressure inside the pipe and outside the leak, and the pipe material ...

  • Thermal–hydraulic modelling of LOCA accident using CONTAIN 2.0 code

    This paper has modelled one of the accidents in the Pressurised Water Reactor (PWR) reactor containment that is known as Loss of Coolant Accident (LOCA) in its worst condition that is called Large Break LOCA (LB LOCA) with the CONTAIN 2.0 code. Specific type of the LB LOCA is Double–Ended Cold Leg (DECL) break that means guillotine break in the cold leg pipe. The coolant is lost when a LOCA ...

  • Hydraulic model comparison of vertical-flow regimes in constructed wetlands

    Vertical-flow treatment wetlands have come into use because of their ability to provide highlevel secondary and tertiary wastewater treatment at a fraction of the land use of horizontal subsurface flow or free water surface wetlands. The flow regime typically selected is vertically downward, allowing wastewater to infiltrate through the system by gravity. However, recent research suggests that ...

  • Hydraulic modeling - Bethel Park Municipal Authority - Case Study

    Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions.  Many existing plants already have a minimal amount of head available for passing peak flows through the system, which ...
