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.

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 the U.S. Army Corps of Engineers' water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. CE-QUAL-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/ or from its GitHub website: https://github.com/EnvironmentalSystems/CE-QUAL-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 PT
$29/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 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.


Workshop 3: Water Conflict Management and Transformation
Sunday, November 6 | 1:30 PM - 5:00 PM PT
$199/person | Registration Limit = 30 Attendees

Only water and coffee will be available in the room.

Meet the Presenters:

Todd Jarvis, Oregon State University
Todd Votteler, Texas Water Journal, Austin
Aaron Wolf, Oregon State University

"Water Conflict Management & Transformation” offers an opportunity for water resources professionals regardless of background to learn about current and leading-edge ways to work effectively in contentious water situations. It explores conflict tolerance, prevention, management, and transformation through collaborative structures as well as through models of negotiation and dialogue. Water management is conflict management. Regardless of the scale, ensuring that the needs of the people and ecosystems that rely on this critical resource are met effectively requires comprehensive understanding of both water science and water conflict management, including dispute mitigation, transformation, and resolution. To address these needs, the instructors have designed a highly interactive approach to capacity-building, including theoretical approaches, case studies, role plays, and serious gaming. The goal of this course is to broaden the scope of approach to the conflicts inevitable in the water world, and to provide a more theoretical dimension to conflict, engage multi-level scales of conflict dimensions and strengthen skills through highly experiential learning opportunities.

Learning Objectives:

  • Increase participants’ understanding of the issue of shared waters from various perspectives and scales.
  • Develop the ability of participants to reframe interpersonal differences and apply this within the context of shared waters.
  • Increase skills of participants to analyze stakeholders, issues and conditions for negotiations within a shared waters context.
  • Introduce the participants to a wide range of negotiation tools, models and frameworks.
  • Provide a space for participants to practice and demonstrate their negotiation/mediation skills.


Workshop 4: Informed Risk Management: Building Probabilistic Water Management Models using GoldSim
Sunday, November 6 | 8:30 AM - 4:30 PM PT
$49/AWRA Members; $149/Non-members; Students = Free | Registration Limit = 20 Attendees

*Participate for a cause! All proceeds will be donated to AWRA for student scholarships.* Lunch is provided.

Meet the Presenter:

Jason Lillywhite, P.E.

This hands-on training session is designed for engineers and scientists involved in modeling and decision support for water resources applications. The focus will be on dynamic simulation and modeling techniques for incorporating uncertainty and evaluating the risk and reliability of water resources. We will use GoldSim software during the class to facilitate learning the concepts. Through hands-on examples, you will practice building your own water management model with a custom user interface, data input, model functions, and result processing for evaluating climate uncertainty and its impact on water quality and quantity of a typical water system. In addition, you will be introduced to scenario analysis, optimization, and results post-processing. If you are new to GoldSim, we recommend that you become familiar with it by working through GoldSim’s free online course.

Course Outline:

  • 8:30 AM – 9:00 AM: Setup
  • 9:00 AM – 10:00 AM: Introduction to dynamic simulation and GoldSim
  • 10:00 AM – 12:00 PM: Building a simple water management model
  • 12:00 PM – 1:00 PM: Lunch (free for all attendees)
  • 1:00 PM – 2:00 PM: Water management control logic
  • 2:00 PM – 3:00 PM: User interface and results
  • 3:00 PM – 4:00 PM: Incorporating uncertainty and simulating risk
  • 4:00 PM – 4:30 PM: Scenarios and post processing
