  • Modeling BMP’s in Sensitive Areas with xpswmm - King’s Beach Watershed Improvement Project - Case Study

    Introduction Located on the border of California and Nevada, Lake Tahoe (the Lake) is the largest alpine lake in North America. It is known for its scenic beauty and outstanding lake clarity. However, the clarity of the Lake has been declining since the mid-1960s because of the deposition of fine particles and nutrients from urban runoff and the growth of aquatic organisms that feed off the ...

  • Numerical and experimental study of the fundamental flow characteristics of a 3D gully box under drainage

    Numerical studies regarding the influence of entrapped air on the hydraulic performance of gullies are nonexistent. This is due to the lack of a model that simulates the air-entrainment phenomena and consequently the entrapped air. In this work, we used experimental data to validate an air-entrainment model that uses a Volume-of-Fluid based method to detect the interface and the Shear-stress ...

  • History of sanitation and hygiene technologies in the Hellenic world

    Sanitation and hygiene technologies have existed in ancient Hellas since the Bronze Age (ca. 3200–1100 bc), when extensive sewerage and drainage and other elaborate sanitary structures were known in Minoan palaces and towns. Classical and Hellenistic periods should be considered as the most progressive eras in the design of sanitary engineering. At that time anatomically shaped ...

  • How to choose open cell or closed cell articulated concrete blocks

    Are you wondering what the best, most cost-effective solution is for erosion control at your construction site? There are a variety of solutions available, but we always highly recommend the use of articulated concrete blocks. These systems are a great alternative to what can otherwise be a costly, time-consuming task in erosion control. Articulated concrete block systems can be used in a wide ...

  • Automating drainage direction and physiographic inputs to the CEQUEAU hydrological model: sensitivity testing on the lower Saint John River watershed, Canada

    CEQUEAU is a process-based hydrological model capable of simulating river flows and temperatures. Despite an active user base, no facility yet exists for the automatic assembly and input of watershed data required for flow simulations. CEQUEAU can therefore be time-consuming to implement, particularly on large (≥104 km2) watersheds. We detail a new MATLAB toolbox designed to remove this ...

  • WaStop Inline Check Valve protects Hull from Flooding - Case Study

    Location:  Hull, United Kingdom Client:  The Environmental Agency, Hull City Council & Associated British Ports Problem:  In December 2013 a storm surge caused water to over top the existing flood defence along the Humber frontage and on the Albert dock causing flooding and widespread damage. Once the water had over topped the ...

  • Membrane technology applied to acid mine drainage from copper mining

    The objective of this study is to evaluate the treatment of high-strength acid mine drainage (AMD) from copper mining by nanofiltration (NF) and reverse osmosis (RO) at pilot scale. The performances of two commercial spiral-wound membranes – NF99 and RO98pHt, both from Alfa Laval – were compared. The effects of pressure and feed flow on ion rejection and permeate flux were evaluated. The ...

  • Case study - Airport platform

    Mexico City's international airport was built over a lake; the soil is expansive clay with water content approaching 200%. Settlement is a severe problem and several airport runways necessitated a 4m asphalt layer thickness. A recently constructed airport platform using a conventional pavement was expected to settle 3 cm at the 3 vertical loading points of the airplane over two years. In fact it ...

  • What Are The Benefits of Commercial Pipe Bursting?

    Repairs become more difficult when commercial aspects are involved. Aside from being disruptive for businesses and time consuming, they can also pose some safety and health hazards for the employees and customers. Trenchless technology has introduced a no-dig solution that can turn a potential sewage or drain problem into one that’s relatively seamless and quick. ...

  • Experimental study of hydraulics and sediment capture efficiency in catchbasins

    Catchbasins (also known as gully pot in the UK and Australia) are used to receive surface runoff and drain the stormwater into storm sewers. The recent interest in catchbasins is to improve their effectiveness in removing sediments in stormwater. An experimental study was conducted to examine the hydraulic features and sediment capture efficiency in catchbasins, with and without a bottom sump. ...

  • Lost in calibration: why people still do not calibrate their models, and why they still should – a case study from urban drainage modelling

    From a scientific point of view, it is unquestioned that numerical models for technical systems need to be calibrated. However, in sufficiently calibrated models are still used in engineering practice. Case studies in the scientific literature that deal with urban water management are mostly large cities, while little attention is paid to the differing boundary conditions of smaller ...
