Detailed SR Function Description
Functional relationship between steelhead survival and stream temperature from laboratory experiments (orange dots, Bear et al. 2007). Points are results of experiments in Bear at al. (2007); blue line is the functional relationship for the productivity multiplier used in the steelhead life-cycle model.
Note: the equation in the Beechie et al. paper has an error in the equation, it is 1+e, not 1-e.
Function Derivation

Function Type
continuous
