Using WinSLAMM Meeting Urban Stormwater Management Goals

See upcoming dates

Course Overview

This hands-on, computer-based course will demonstrate how the latest WinSLAMM software incorporates long-term local rain data along with soils, land use, source area, and other local watershed factors to quantify pollutant sources in complex urban watersheds.

Learn how to use WinSLAMM to:

  • calculate pollutant loads and runoff volumes, the cost of stormwater control practices, and runoff volume impacts from porous pavement
  • analyze outlet options for wet detention ponds, street dirt washoff and catch basin cleaning, and whether biofilters meet regulatory requirements
  • estimate the effectiveness of filter strips, rain barrels and cisterns, hydrodynamic treatment devices, stormwater media filters, and grass swale drainage systems.

Who Should Attend?

  • Design engineers
  • Architects
  • Contractors
  • Developers
  • Regulators 
  • Reviewers 
  • Regional planning staff
  • City or county staff with stormwater management responsibilities

Roger Bannerman

Roger Bannerman, environmental specialist, has worked for the Wisconsin Department of Natural Resources for over 35 years. For most of that time he has directed research projects investigating the solutions to problems caused by urban runoff. His research has served as the basis for the development of technical standards, administrative rules, and the calibration and verification of WinSLAMM.

Doug Joachim

Doug Joachim has been a water resources engineer in the private sector since 2012. He is a consulting engineer with AECOM (in Minneapolis, Minnesota), where he works on a variety of projects related to water quality and hydrologic and hydraulic modeling.

He first used WinSLAMM as a beta tester prior to the release of version 10.0, and has since had extensive experience using WinSLAMM on both small- and large-scale projects. He has been a member of PV & Associates since early 2014.

Caroline Burger

Caroline Burger, PE, AECOM water resource engineer, has years of experience in stormwater management planning, pollution modeling and monitoring, hydrologic and hydraulic modeling, stormwater permitting, ordinance development, and analysis of BMPs. She has extensive experience using WinSLAMM and has been a key part of the team involved with the calibration and development of the WinSLAMM model.

Ned Paschke

Ned Paschke, PE, DEE, is a program director and professor of practice at the University of Wisconsin-Madison, specializing in analysis and improvement of water and wastewater systems and facilities. Before joining the UW-Madison, he was director of engineering for the Madison Metropolitan Sewerage District and a hydraulic engineering consultant for national and international engineering firms.

Robert Pitt

Robert Pitt, PhD, PE, BCEE, D.WRE is Cudworth Professor of Urban Water Systems at the Department of Civil, Construction and Environmental Engineering, University of Alabama. Pitt is a nationally recognized authority on the modeling, detection, and control of contaminants in urban drainage systems and 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.

Howard Rosen

Howard Rosen is a Program Director in the Department of Engineering Professional Development, College of Engineering, at the University of Wisconsin–Madison. He specializes in developing continuing education programs on issues in public works infrastructure. Rosen’s academic research interest is in the dynamics of technological development and organizational change and he has written and taught extensively on these subjects. Rosen received his doctorate from the Division of Social Sciences of the University of Chicago. He was a member of the Stanford University (Program in Values, Technology & Society) and on the faculty of the Illinois Institute of Technology.

John Voorhees

John Voorhees, PE, PH, AECOM senior water resource engineer, is co-author of WinSLAMM (Source Loading and Management Model). 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 BMP design, regulatory compliance, and evaluation of BMP effectiveness.
