  • Analyzing the turbulent flow on steep open channels

    In channels with steep slopes, the flow is supercritical and the formation of roll waves is expected. In order to evaluate the flow behaviors in steep open channels, the Azad dam spillway is simulated numerically and its flow characteristics are compared with the physical model tests. In this study, the hydraulic variables including hydraulic depth and water surface profile are studied along ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...

  • Numerical analysis of hydraulic jumps using OpenFOAM

    The present paper deals with a hydraulic jump study, characterization and numerical modeling. Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that increases the shear stress on streambeds, so promoting their erosion. A three-dimensional computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth rectangular prismatic open-air ...

  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Vibrating feeders for stockpiling and reclaim

    The expanding applications of vibratory feeders for controlling the flow of bulk materials, and their adaptation for processing requirements, have developed considerable interest in stockpiling and reclaim systems. The general design of these units consists of a material transporting trough, or platform, driven by a vibratory force system. The flexibility and variety of designs is limited only by ...

  • A no-brainer for drains

    Pre-fabricated drainage products have saved time and boosted safety on a Welsh road scheme Surface water drainage is not the most visible element of a new road scheme – after all, it’s almost entirely underground. But it is vitally important to any road and it’s one of the first priorities before work starts on the carriageway. At Costain’s £59 ...

  • Balancing growth and conservation - Precast concrete manholes become part of the stormwater solution

    When American Fork, Utah, decided to approve construction of a 175-acre commercial center, the city engineers had to consider the environmental effect it would have on a 45-acre wetland right next door. Under the EPA´s Phase II Storm Water Rules, adapted in late 1999, almost any city large enough to require a storm sewer system must balance growth with the environmental impacts of ...
