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.
