“Introduction to CE-QUAL-W2” – free webinar EPA’s Water Quality Modeling

EPA’s Water Quality Modeling Workgroup is hosting a series of webinars to help water quality professionals better understand surface water quality modeling and how models can be used to solve common problems that face water quality regulators. The webinars are focused on modeling as it applies to the Total Maximum Daily Load (TMDL), Standards, and Water Quality Permitting Programs, but they are applicable to a wide range of audiences. These two hour webinars cover everything from modeling basics (e.g., model setup and calibration) to applied water quality modeling of different pollutants.

The webinar, titled “Introduction to CE-QUAL-W2”, is scheduled for Thursday, November 15 at 1pm Eastern.  This webinar will introduce CE-QUAL-W2, a 2-dimensional hydrodynamic and water quality model that has been applied to a wide range of water quality problems in rivers, lakes, reservoirs, and estuaries. The model provides time-varying simulation of conventional water quality parameters including temperature, nutrients, algae, dissolved oxygen, pH, and sediment. Originally created by the Corps of Engineers, the current release was developed under supervision of Dr. Scott Wells at Portland State University. Topics to be addressed during this webinar include W2’s basic functionality and application, limitations of W2, typical applications, development efforts, case examples (stratified reservoirs, river system with riffles and stratified pools), and 2 example problems.
