Estimation of groundwater flow rate by an actively heated fiber optics based thermal response test in a grouted borehole

The dataset contains the numerical data and the in-situ measurements in the manuscript titled "Estimation of groundwater flow rate by an actively heated fiber-optics-based thermal response test in a grouted borehole". The data is stored in MAT files, which are Binary MATLAB files. There are a series of codes used in this manuscript to estimate groundwater flow rates. The codes were written in MATLAB Live Script, version 2021b.

The numerical data contains temperatures of the heating stage in different thermal response tests in a numerical model, which considers the borehole effects. The model is set up by COMSOL Multiphysics, and a series of flow rates is set to the model respectively for different thermal response tests.

The in-situ measurements include temperatures of the heating stage in an actively heated fiber-optics-based thermal response test, which was performed in July 2021 in the grouted borehole, which is located in the lower section of the Sima bend of the Yangtze River. The temperature for the flow rate estimation was thinned to 120 s records from 10s records for the limited computing resources.

The data_process.mlx provides pre-processing for the observational data recorded by Silixa Ultima-M MK2 DTS. The estimation_process.mlx gives a groundwater flow estimation case in a grouted borehole.
