Heat Source Methodology Review


Heat Source is a computer model used by Oregon DEQ to simulate stream thermodynamics and hydrology. It was developed in 1996 as a Masters Thesis at Oregon State University in the Departments of Bioresource Engineering and Civil Engineering. DEQ currently maintains the Heat Source methodology and computer programming. Appropriate model use and application are the sole responsibility of the user.
