1DTempPro V2: New Features for Inferring Groundwater/Surface-Water Exchange

Area of Science:

• Hydrogeology
• Computational Modeling
• Environmental Science

Background:

• Accurate assessment of groundwater/surface-water interactions is crucial for water resource management.
• Estimating hydraulic conductivity often requires sophisticated numerical models.
• Previous versions of 1DTempPro facilitated analysis of one-dimensional temperature profiles.

Purpose of the Study:

• To introduce a new version of the 1DTempPro computer program with enhanced functionalities.
• To extend the capabilities for analyzing vertical one-dimensional temperature profiles under saturated flow conditions.
• To improve the estimation of hydraulic conductivity and assessment of groundwater/surface-water exchange.

Main Methods:

• The enhanced 1DTempPro program serves as an interface to the U.S. Geological Survey's VS2DH model.
• New capabilities include automated parameter estimation.
• The model now incorporates layer heterogeneity and time-varying specific discharge for more realistic simulations.

Main Results:

• The updated software provides advanced tools for analyzing temperature profiles in saturated subsurface flow.
• Automated parameter estimation streamlines the process of determining model parameters.
