An Open Source Package to Create Input Files for Simulations using the Stream Network Temperature (SNTEMP) Model

The DOS based Stream Network Temperature (SNTEMP) model is a comprehensive physics-based model can be very difficult to run because it requires seven formatted input files that are very time consuming and difficult to create. A general open source package, SNTempInput was developed to create the required SNTEMP input files from a defined stream network, meteorological, and hydrological data required to drive the SNTEMP simulations. The software is intended to reduce the amount of time required to set up and run SNTEMP simulations to facilitate stream temperature related research and practice. This paper describes how to format the required data files and use SNTempInput to create properly formatted input files for SNTEMP. The paper provides guidance as to how and where to make any necessary modifications to the source code so that SNTEMP can be coupled with output from any hydrologic modeling software.
