Workshop on WDN analysis WDNetXL (see flyer)

Registration: CCWI online store (see instructions)

Date:
Sunday 4th September 12:00 – 17:00 hrs

Location: Peter Chalk Centre, University of Exeter

Leaders: Professor Orazio Giustolisi, Technical University of Bari, Professor Dragan Savic and Zoran Kapelan, University of Exeter.

Developers of WDNetXL: Dr. Luigi Berardi and Dr. Daniele Laucelli, Technical University of Bari.

Description
This seminar is intended for practitioners and researchers and its objective is to provide key ideas and tools for WDN analysis and design within a comprehensive and consistent framework using excel as the interface. The problem of WDN hydraulic simulation will be tackled by using both a classic demand-driven approach and the most recent pressure-driven upgrades. Water leakages will be introduced in pressure-driven hydraulic simulation. The seminar will identify the association between isolation valves and pipe segments and the automatic detection of connected WDN topology, after valve shutdowns. The optimal design of pipe diameters and of a system of isolation valves in a WDN will be considered.

During the seminar the WDNetXL will be presented and distributed to participants. WDNetXL offers a complete range of MS-Excel functions including several analyses of WDNs. The key features of WDNetXL are:

  • It is self standing and readily usable without any additional software application;
  • It is fully integrated in MS-Excel format;
  • It sets parameters, input and output data intuitively arranged in MS-Excel spreadsheets.

A Workshop on Stormwater Pollution Modeling for Urban Water Management Systems and An Introduction to WinSLAMM, The Source Loading and Management Model

Registration: CCWI online store (see instructions)

Date: Sunday 4th September 2011; 12:00 - 17:00 hrs

Location: Peter Chalk Centre, University of Exeter

Leaders:

  • Robert Pitt, PhD, PE, BCEE, D.WRE, Cudworth Professor of Urban Water Systems in the Department of Civil, Construction, and Environmental Engineering, University of Alabama. Robert Pitt is an internationally recognized authority on the modeling, detection, and control of contaminants in urban drainage systems. He has been recognized for his work on the development of new analytical methods for the rapid and sensitive detection of toxicants. He is the author of more than 100 books, journal articles, and reports, and recipient of numerous honors and awards from various national engineering and environmental organizations.
  • John Voorhees, PE, PH, Senior Water Resource Engineer, AECOM. John Voorhees is co-developer of WinSLAMM. He has 21 years of experience on many aspects of stormwater management in both the public and private sectors, with extensive experience working on innovative stormwater control design, regulatory compliance, and evaluation of stormwater control effectiveness.

Description
This seminar will introduce stormwater pollution modeling for urban watersheds based around the WinSLAMM simulation and decision analysis tool. It is intended for practitioners and researchers’ and will include some hands-on computer-based demonstrations of how to use WinSLAMM to assess source area stormwater controls to maintain or create hydrologically functional landscapes that mimic natural watersheds’ hydrologic functions (volume, frequency, recharge, and discharge). By integrating source area controls into site design and leveraging small catchment hydrology together with historical time series rainfall, you can approach the pre- development site’s ability to retain water and pollutants.

Participants will be introduced to various stormwater quality management issues, including:

  • Introduction to stormwater pollution modeling in complex urban watersheds;
  • Predicting the performance and impact of interacting development and control options;
  • Calculating pollutant loads and runoff volumes from examples of structural and non-structural management scenarios.

About WinSLAMM
WinSLAMM is a Windows-based, continuous simulation computer program, that helps water resources professionals and environmental engineers make effective decisions by modeling the stormwater impacts of new or existing developments and evaluating the benefits of various control measures. The WinSLAMM model has been continuously developed and expanded since the 1970s and is used to calculate urban stormwater runoff volume, pollution loads, and assess a wide range of management measures, including: public works practices of street and catchbasin cleaning, grass swales, roof and pavement disconnections, beneficial use of stormwater, sedimentation devices such as wet detention ponds and hydrodynamic devices, bioretention/biofilters and infiltration devices, green roofs, and media filtration. The model enables accurate planning-level and design-level analyses, including life-cycle costs. Wisconsin’s Department of Natural Resources for example has adopted the model for regulatory compliance purposes. The WinSLAMM batch processor provides data for decision makers to select the most cost-effective alternative stormwater control practices. WinSLAMM is typically used in continuous simulations of at least one year of local rain events to examine these issues over a wide range of actual site conditions.

Programme
The half-day course will cover:

  • Stormwater Pollution Modeling - terminology and preparing to model;
  • WinSLAMM  - theory, practice, model features and navigation
  • Analyzing  example urban developments for stormwater volume & TSS loads and retrofit controls
  • Examples of stormwater control modeling including , grass swaless, biofilters/infiltration devices, and proprietary filters

Prerequisite
This workshop requires attendees to have a laptop computer with them for use during the session. Attendees will be provided a temporary license of the model for use during the course. WinSLAMM can be run on a PC with Windows XP, Vista, or Windows 7, and will need a USB port to load the program (or an Internet connection to download the trial version). You will need administrative privileges for the computer if the program is not pre-loaded. It is recommended that participants pre-load the model before attending the workshop to ensure that proper computer administrative authority for the operating system has been obtained. The trial version is available at: http://www.winslamm.com/winslamm_updates.html. Contact John Voorhees to obtain the limited term license for the trial version at: This e-mail address is being protected from spambots. You need JavaScript enabled to view it . It is anticipated that the new Version 10 of the model will be used during this workshop.
