Stormwater Management Case Studies and White Papers

  1. White Paper: Evolution Of An Integrated 1D/2D Modeling Package For Urban Drainage
    Recent flooding events in North America have revealed deficiencies in existing stormwater infrastructure and management practices. The development of effective and efficient designs requires a comprehensive understanding of flooding in urban areas and complex open channel and overland flow systems. By XP Software
  2. Case Study: 1D And 2D Modelling Of Urban Drainage Systems Using XP-SWMM And TUFLOW
    As part of the on-going development of the XP-SWMM modeling system to enhance its functionality and its capability to model urban drainage systems the TUFLOW 2D hydrodynamic model is being incorporated as a layer into an XP-SWMM2D package. By XP Software
  3. Case Study: XP Software Water Re-Use At The Sydney Olympics
    Based on our prior preparation of the stormwater management strategy and concept design for stormwater infrastructure at the Homebush Bay Olympic Site in Sydney, XP Software has been engaged since 1995 to provide specialist advice to the Olympic Co-ordination Authority (OCA) on a project by project basis. The scope of each project, inputs, approach, and outputs were agreed with OCA prior to commencing to ensure an integrated management approach. By XP Software
  4. Case Study: Bioecods Modelling Using SWMM
    The Bio-Ecological Drainage System (BIOECODS) is a pilot project that meets the requirement of Storm Water Management Manual (MSMA), which is designed for water quantity and quality controls. BIOECODS has been constructed at Engineering Campus, University Sains Malaysia, Nibong Tebal, and Pulau Pinang. BIOECODS forms an alternative to storm water management practice and built in environmentally friendly manner. By XP Software
  5. Case Study: XP Software Kawana Waters Project
    XP-Storm has been used successfully by Cardno MBK to model very large urban catchments with multiple outlets and complex major storm flow paths. By XP Software
  6. White Paper: An Integrated Modeling Approach To Predict Flooding On Urban Basin
    Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of river during severe rainfall event. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural development, and therefore, the correct prediction of surface runoff is becoming a challenging issue. By Dr Ashis Kumar Dey and Seiji Kamioka
  7. Case Study: Creating A Comprehensive Stormwater Model In A Challenging Environment
    Data including location coordinates, crown elevation, and invert depths were collected for each structure, and information such as structure dimension and composition were collected for each pipe using Global Positioning System (GPS) technology. As soon as the inventory was finished, it was converted into database format that could then be imported into the stormwater models. By Matthew Luth, Civil Engineer, Burns & McDonnell
  8. Case Study: XP Software Cape Coral Canal Project
    Develop a Storm Water Management Model using XP-SWMM to simulate a scenario of one-foot higher elevation for selected weirs. By Southern DataStream
  9. Case Study: Vancouver Public Library Green Roof Monitoring Project
    The Vancouver Public Library’s (VPL) Central Branch building and green roof were constructed in 1995. The 2,600 m2 (28,000 sq.ft.) roof includes an extensive green roof with a gross area of 1850 m2 (20,000 sq.ft.) and a net area of 1,500 m2 (16,150 sq.ft). The green roof was designed and completed by architect Moshe Safdie and Landscape Architect Cornelia Hahn Oberlander. By Chris Johnston P.Eng., Kathryn McCreary B.A.Sc., Cheryl Nelms, B.Eng.
  10. Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection

    The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation
