Workshop 1: Surface Water Quality Modeling with CE-QUAL-W2
Sunday, November 6 | 8:30 AM - 12:30 PM ET
$49/person | Registration Limit = 20 attendees

Only water and coffee will be available in the room; breakfast and lunch are available on your own.

Meet the Presenters:

Zhonglong Zhang, PhD, PE, PH
Research Professor Department of Civil & Environmental Engineering
Portland State University

Todd Steissberg, PhD, PE
Research Environmental Engineer
Environmental Laboratory
U.S. Army Engineer Research & Development Center (ERDC)


To provide attendees with the knowledge to effectively utilize the latest CE-QUAL-W2 model to perform two-dimensional water quality modeling and analysis in support of reservoir and riverine water quality, environmental impact assessment, and ecosystem restoration projects. The workshop is designed for practicing engineers and scientists in consulting engineering, city, state and federal agencies, research organizations, and academic institutions.


8:30 AM - Welcome and introductions
8:45 AM - Overview of CE-QUAL-W2
9:30 AM - Break
9:40 AM - Water quality data requirements, model development, calibration, demo
10:40 AM - Break
10:50 AM - Model utility intro and Hands-on exercises, etc.
12:30 PM - Adjourn


CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships. The current model release is Version 4.5. CE-QUAL-W2 can be freely accessed and downloaded from the Portland State University website: http://www.ce.pdx.edu/w2/.


Topics to be covered include an overview of CE-QUAL-W2 model; hydrodynamics and transport modeling; water quality capabilities in CE-QUAL-W2; water quality model data requirements and inputs; setting up a water quality model for simulating water temperature, general constituents, and nutrients; water quality model calibration and sensitivity analysis.

Take Aways:

Having completed this course, attendees will gain a working knowledge of the CE-QUAL-W2 water quality model. Through a combination of lectures and hands-on exercises, attendees will learn to use CE-QUAL-W2 to set up, calibrate, and validate a river water quality model and perform an analysis of water temperature, general constituents, and eutrophication.

Attendee Requirements:

Attendees are encouraged to bring their own notebook computer. In addition participants should have administrator privileges on their computer in order to install the software. HOWEVER, participants are welcome to attend the workshop without a computer with the understanding that one will not be provided.

Workshop 2: Using A Temporal-based Approach to Quantify Streamflow Properties
Sunday, November 6 | 10:00 AM - 12:00 PM ET
$29/person | Registration Limit = 20 ATTENDEES

Meet the Presenter:

Richard Koehler, PhD, PH
CEO of Visual Data Analytics and a certified professional hydrologist
Visual Data Analytics


This workshop is for anyone working with streamflow time-series where the classic properties of magnitude, frequency, duration, timing, and change-in-flow (a.k.a. flashiness) are important to quantify. Specifically, the workshop will give an overview of autocorrelation lag(k) plots and their conventional use. The discussion will then transition to sequence summations and how these values are tied to streamflow properties. Topics covered include autocorrelation, theoretical development of the technique presented, interpretation of results, and the use, limitations, and application of this technique. NOTE: Students must bring their own computers preloaded with MS Excel (minimum requirement). Additional Window-based software will be provided.

Learning Objectives:

  1. Recognize the additional information available in lag(k) plots.
  2. Execute a spreadsheet-based alternate sequential-based analysis.
  3. Identify the uses and limitations of the techniques presented.
  4. Interpret the resulting graphic products for hydrologic importance.

Conference & Workshop Registration

Workshop Registration Only


All conference participants (presenters, moderators, panelists, etc.) must register at the appropriate registration rate. AWRA Gateway members are not eligible for discounted conference rates. The registration fees are the major source of funding for the Conference, and the sharing of registrations is prohibited - every person attending the conference must register. For presenters, if two or more individuals will be presenting, each individual must register for the conference. This includes: all technical session presenters; all panel session presenters; and all poster session presenters.

All conference participants must adhere to the AWRA Code of Conduct. Cancelations must be made in writing. Refunds are not allowed for Early Bird Rates. We can transfer your registration to someone else by October 19, 2022. Those cancelations received by October 19, 2022 will be subject to a processing fee of 25% of total fees. No refunds will be given after October 19, 2022 - no exceptions! Abstract submission fees are nonrefundable. Refunds will be processed after the conclusion of the conference.


If you actively engage in our community, your career and organization will benefit. We offer multiple opportunities for engagement via conferences, social media, webinars, committees and publications.
