CANCELLED: Workshop 3: River Water Quality Modeling with HEC-RAS 5.1
Instructors: Zhonglong Zhang, Portland State University; Todd Steissberg, U.S. Army Engineer Research and Development Center; Dan Rucinski, LimnoTech
To provide attendees with the knowledge to effectively utilize the latest HEC-RAS software to perform one-dimensional river water quality modeling and analysis in support of Total Maximum Daily Load (TMDL) development, environmental impact assessment, and ecosystem restoration projects. The course is designed for practicing engineers and scientists in consulting engineering, city, state and federal agencies, research organizations, and academic institutions.
HEC-RAS software is a river analysis model developed and maintained by the U.S. Army Corps of Engineers. HEC-RAS is an industry standard hydraulic tool that has been used worldwide. HEC-RAS can be freely accessed and downloaded from the HEC website: http://www.hec.usace.army.mil. A set of plug-in water quality modules have been integrated into the latest version of HEC-RAS and released from HEC-RAS 5.1.
Topics to be covered include an overview of HEC-RAS software; river hydraulics and unsteady flow modeling; transport and water quality modules in HEC-RAS; water quality user interface, 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.
Having completed this course, attendees will gain a working knowledge of the HEC-RAS water quality model. Through a combination of lectures and hands-on exercises, attendees will learn to use HEC-RAS to set up, calibrate, and validate a river water quality model and perform an analysis of water temperature, general constituents, nutrients, and eutrophication.
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. Experience with HEC-RAS and water quality is a plus.
