HFLUX is a one-dimensional transient model that calculates stream temperatures with respect to space and time using the mass and energy balance equations for temperature transport in streams. It uses initial spatial and temporal temperature boundary conditions, stream dimension information, discharge data, and meteorological data to calculate stream temperature using a finite difference method. HFLUX is written as a set of functions that run in the MATLAB environment. More information can be found in the HFLUX Documentation.

Updates from HFLUX 3.0 to 3.1: Line 61 of the hflux_sensible.m file was modified to replace “z” with “z_met.” The equation was modified to use the height at which the wind speed is measured, rather than the elevation of the station, which was an error in the code.
