1DTempPro: A program for analysis of vertical one-dimensional (1D) temperature profiles


1DTempPro is a computer program for the analysis of one-dimensional vertical temperature profiles. The program is a graphical user interface (GUI) to the previously published USGS code VS2DH, which numerically solves the flow and heat-transport equations. The program allows users to visually calibrate VS2DH models against measured data to estimate vertical groundwater/surface-water exchange and also hydraulic conductivity for cases where hydraulic head is known. 1DTempPro is written in C# for execution in a MS Windows .NET environment.

How to Cite

This USGS software has two citations associated with it.

  1. The report citation is for the original report or article documenting the underlying theory, methods, instructions, and (or) applications at the time the initial version of the software was released. This digital object identifier (DOI) is for the report.
  2. The software release citation is for the software/code itself (now referred to by USGS as a "Software Release") and references a specific version of the code and associated release date. This DOI links to the code.

In instances where an author is citing use of this software, it would be appropriate to cite both the report documenting the code and the specific software release version that was used.
