  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • Delta drainage and irrigation system, complex multifunction hydraulic system analysis

    Introduction: Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) ...

  • Experimental and numerical investigation of interactions between above and below ground drainage systems

    This paper presents the results of the experimental and numerical investigation of interactions between surface flood flow in urban areas and the flow in below ground drainage systems (sewer pipes and manholes). An experimental rig has been set up at the Water Engineering Laboratory at the University of Sheffield. It consists of a full scale gully structure with inlet grating, which connects the ...

  • Comparison between InfoWorks hydraulic results and a physical model of an urban drainage system

    Urban drainage systems are frequently analysed using hydraulic modelling software packages such as InfoWorks CS or MIKE-Urban. The use of such modelling tools allows the evaluation of sewer capacity and the likelihood and impact of pluvial flood events. Models can also be used to plan major investments such as increasing storage capacity or the implementation of sustainable urban drainage ...

  • Multi-objective rehabilitation of urban drainage systems under uncertainties

    Urban drainage systems are subject to many drivers which can affect their performance and functioning. Typically, climate change, urbanisation and population growth along with aging of pipes may lead to uncontrollable discharges and surface flooding. So far, many researchers and practitioners concerned with optimal design and rehabilitation of urban drainage systems have applied deterministic ...

  • The hydrogeochemistry of the Lake Waco drainage basin, Texas

    The origin of surface water chemistry in highly impacted drainage basins must be investigated on a drainage-basin scale if the causes of the pollution are to be elucidated. This study characterizes and deciphers the surface water chemistry of a nutrient polluted river system in central Texas. Four tributaries of the Lake Waco reservoir were chemically characterized temporally and spatially in ...

  • Rain water meets thermal water – Drainage system in wellness-oasis

    The new “Kristall swim and health spa” in Ludwigsfelde is going to be the “finest spa resort” in Europe, the investor believes. On 4 November 2005, only five months after laying the foundation, the work was finished. The celebration crown was mounted on top of the wooden frame for the transparent dome roof, under which visitors will enjoy Mediterranean wellness delights. 300,000 visitors are ...

  • 1D & 2D modelling of urban drainage systems using xpswmm and Tuflow

    Introduction: The release of a revised New South Wales (NSW) Floodplain Management Manual in 2001 established a new direction for urban flood management in NSW. This new direction was created by a redefinition of the floodplain as the area bounded by the Probable Maximum Flood (PMF) – this poses a challenge to estimate PMF flooding in highly urban areas and particularly in piped ...

  • Development of a regression model to predict copper toxicity to Daphnia magna and site‐specific copper criteria across multiple surface‐water drainages in an arid landscape

    The water effect ratio (WER) procedure developed by the U.S. Environmental Protection Agency is commonly used to derive site‐specific criteria (SSC) for point‐source metal discharges into perennial waters. However, experience is limited with this method in ephemeral and intermittent systems typical of arid climates. This study presents a regression model to develop WER‐based SSC for a network ...

  • GIS applications in urban drainage master planning

    Introduction: The City of Stratford, Ontario, located 150 km (94 mi.) west of Toronto, initiated the development of an infrastructure asset database in the early 1990’s and continues to develop digital mapping to support the maintenance and management of municipal services. In continuing these efforts, the City initiated the City-Wide Storm System Master Plan (the Study) in 2002 to ...

  • Characterization of the hydraulic performance of a gully under drainage conditions

    During rainfall events with low return periods (1–20 years) the drainage system can provide some degree of protection to urban areas. The system design is based not only on good hydraulic performance of the surface and the sewer network but also on their linking elements. Although the linking elements are of utmost importance as they allow the exchange of flow between the surface and the ...

  • Automated Measurement of Slurry Surface Settlement

    An automated float method for measuring slurry surface settlement is described. The system consists of a Perspex float which is denser than water but lighter than the slurry into which it penetrates slightly and floats on the slurry/water interface. Settlement of this float is then automatically tracked using an LVDT. Comparison with direct cathetometer measurement demonstrates that except for ...

  • Treatment of heavy metals by iron oxide coated and natural gravel media in Sustainable urban Drainage Systems

    Sustainable urban Drainage Systems (SuDS) filter drains are simple, low-cost systems utilized as a first defence to treat road runoff by employing biogeochemical processes to reduce pollutants. However, the mechanisms involved in pollution attenuation are poorly understood. This work aims to develop a better understanding of these mechanisms to facilitate improved SuDS design. Since heavy metals ...

  • Use of InfoWorks CS to build an integrated urban drainage model

    Creation of a single integrated InfoWorks CS model covering foul, surface and river systems is proving invaluable in understanding the complex interactions within a flood-prone urban catchment in north west London. The three systems had originally been held in separate models, with the foul and surface networks each modeled in InfoWorks CS and the rivers in ISIS. “There has been a lot of careful ...
