Aug 1, 2005: Final date for authors to submit 1st draft of paper (pdf to Ostfeld)
Sep 20, 2005: Provide 1st round review comments to authors, including preliminary decision
Nov 1, 2005: Final date for authors to submit 2nd draft of paper
Nov 25, 2005: Provide 2nd round review comments to authors, including final decision

Dec 31, 2005: Editor sends approved final versions to ASCE for copyediting

Please forward this message to any additional authors who might be interested in this initiative.

Sincerely yours,

Avi Ostfeld

From HydroCAD web site:

HydroCAD-7 is a Computer Aided Design tool used by Civil Engineers for modeling stormwater runoff. HydroCAD provides a wide range of commonly used drainage calculations including:

  • SCS, NRCS, SBUH runoff hydrographs
  • Rational Method with automatic IDF curves
  • Hydrograph routing through ponds & reaches
  • Coupled ponds with automatic tailwater
  • Automatic hydraulics and culvert calculations
  • Automatic pond storage calculations, including embedded storage chambers
  • Easy management of multiple rainfall events

HydroCAD is ideal for studies using the TR-20, TR-55, or SBUH methods. HydroCAD provides a wide range of standard H&H techniques in an easy-to-use graphical form, managed by the on-screen routing diagram we pioneered in 1986.

For more information see HydroCAD web site.

From HYDRA web site:

HYDRA® software is a full-featured program used by environmental and civil engineers to model and design urban drainage systems. It helps you estimate wastewater flows, and then calculates the resulting hydraulics within the collection system. It provides tools for managing all types of flows, including sanitary wastewater, stormwater inflow, rainfall-dependent infiltration, and groundwater infiltration. It helps you understand how the whole sewer system works under various conditions — today and in the future – and identify potential problem areas. HYDRA® software creates preliminary design for new sewers and suggests improvements for existing systems. It helps you optimize your pipe network, and find the most cost-effective way to solve system problems. The HYDRA® program has been used by thousands of engineers since its first commercial release in 1973.

For more information see HYDRA web page.

4/27/2005 Cincinnati, OH – Civil and environmental engineers now have an improved software tool, the Storm Water Management Model (SWMM), to help plan, analyze, and design urban storm water drainage and sewer systems. This latest revision to SWMM includes several improvements not available in previous editions. These include a modern graphical user interface, a more intuitive modeling approach, and improved computational speed. SWMM continues to be open source and its numerical engine can easily be integrated into third-party interfaces.

From MWH Soft web site:

H2OMAP Water provides the most powerful and practical GIS platform for water utility solutions. As a stand-alone GIS-based program, H2OMAP Water combines spatial analysis tools and mapping functions with sophisticated and accurate network modeling for complete infrastructure (asset) management and business planning. It performs fast, reliable and comprehensive hydraulic and dynamic water quality modeling, energy management (with true variable speed pumping), real-time simulation and control with on-line SCADA interface, complete fire flow analysis, and unidirectional flushing. The program can also be effectively used to analyze pressurized sewer collection system.

Hydraulic Modeling Capabilities:

  • places no limit on the size of the network and number of components that can be analyzed (unlimited link version)
  • supports both English and metric (Standard International) units
  • analyzes steady-state and extended period simulations
  • computes friction headloss using the Hazen-Williams, Darcy-Weisbach, or Chezy-Manning formulas
  • includes minor (local) head losses for bends, meters, fittings, etc.
  • models constant or variable speed pumps
  • models a fixed pressure pump (FPP) that automatically adjusts its speed to maintain a user specified target pressure (or head) anywhere in the system
  • models turbines and totalizing flow meters
  • calculates Net Positive Suction Head requirements (available NPSH, required NPSH, and cavitation index) to ensure cavitation free operation
  • determines system head curves and fire hydrant rating curves
  • calculates available and design fire flows at minimum residual pressures
  • computes pumping energy and cost based on variable electricity and demand charges
  • accommodates various types of static and dynamic control valves including shutoff, check, float, pressure reducing, pressure sustaining, dual pressure regulating (maintain downstream and upstream pressures), pressure breaker, vacuum breaker, motorized throttled, general purpose, flow control, and reduced pressure backflow prevention valves
  • allows single and multiple inlet/outlet storage tanks to have any shape (i.e., diameter can vary with height)
  • models constant and variable head reservoirs
  • considers multiple demand categories at nodes, each with its own pattern of time variation
  • models pressure-dependent demand issuing from emitters (sprinkler heads)
  • automatically carries out pressure-demand analysis to compute the percentage (%) of demand supplied to each node (ratio of actual demand vs specified demand)
  • tracks flow reversals for pipe flushing
  • determines pipe sequences for unidirectional flushing
  • simulates leakage in a pipe
  • specifies system operation based on both simple node pressure, tank level, link flow, or timer controls and on complex rule-based controls
  • provides on-line SCADA interface with alarms

From the Perf-Q web site:

Performance-Q ג€“ Perf-Q for short ג€“ is a water quality model applicable to drinking water transmission and distribution systems. It is based on an event-driven advection and mixing model, and includes the capability to simulate the propagation and transformation of physico-chemical and microbiological parameters throughout water networks.

Perf-Q uses Epanet standard script input files to perform a complete hydraulic and water quality extended-period simulation. It models chlorine (free and combined), suspended bacteria, organic matter and travel time, taking account of such ambient variables as pH, temperature and pipe biofilm load. The event-driven Lagrangean advection and mixing model provides a basis for taking account of all such parameters and variables simultaneously and model their transformation taking into consideration both their inter-relationships and the influence of hydraulic variables such as flow velocity.
