RNWDC -RNWDC,PCOL,QTS. Where: F - NWDC format flow in one set of units G - same data in altered set of units CAUTION: Use the editor to change the units in the title line of the output file. RUNITS allows conversion of the units in a flow time series from acre-feet per month (AF/mo) to average cubic feet per second (CFS), from CFS to AF/mo, from 1000 AF/mo to CFS, or from CFS to 1000 AF/mo. These conversions are useful in manipulating various data sources to provide flow time series to use in generating habitat time series. Be sure the units in your file title are correct. RHBTMP -RHBTMP,PCOL,F,G,C,HBMOD Where: F - habitat time series from RHABTS for a given study location. G - temperature time series in NWDC format for the same site. C - suitability-of-use criteria values for temperature MODTP - temperature modified habitat time series file for specified location in the stream system • Files F,G,C,and HBMOD may be substituted. CAUTION: The temperature suitability curve values should exceed the range of temperatures anticipated at the study site. Extend the curve as needed. RHBTMP modifies a single life stage fcs for a specified location by adding another multiplicative suitability-of-use factor based on temperature. This assumes a uniform temperature distribution across the width and depth of the stream at the selected site. The effect of this temperature modification will be to reduce habitat area during the months when adverse temperature conditions exit for the selected life stage at the study site. The file containing coordinates of a temperature suitability-of-use curve may be input using procedure RTPREF. RTP RE F -RTPREF,PCOL,F Where: F - file of the coordinates of a temperature suit- ability-of-use curve created by this procedure RTPREF allows the user to interactively build a suitability-of-use curve file for temperature. • 42
