Geophysical and Other Data From an Irrigation Monitoring Experiment at Haddam Meadows, CT, July 2019
October 21, 2022
An irrigation monitoring experiment was performed in Haddam Meadows State Park, Connecticut, on July 16, 2019. Prior to this experiment, ground penetrating radar (GPR), frequency domain electromagnetics (FDEM), and electrical resistivity tomography (ERT) geophysical data were collected over a 20 meter by 10-meter grid to provide baseline information. A vertical soil moisture probe was installed in the center of this area that recorded volumetric water content, temperature, and electrical conductivity at 9 discrete depths down to 1 meter below land surface. Over the next 8 hours, 5,300 liters of irrigation water (with specific conductance of 1,000 microSiemens per centimeter) was sprayed as evenly as practical over an 8 meter by 3-meter area in the center of the study grid. During this time, 3 ERT datasets were collected. At the end of the experiment, another ERT dataset was collected, as well as a final GPR and FDEM data grid. Finally, a push-style probe was used to gather post-irrigation soil moisture conditions from several points and depths (maximum of 0.75 meters below land surface) within the study grid (62 total data points were collected).

Field evaluation of semi-automated moisture estimation from geophysics using machine learning
Geophysical methods can provide three-dimensional (3D), spatially continuous estimates of soil moisture. However, point-to-point comparisons of geophysical properties to measure soil moisture data are frequently unsatisfactory, resulting in geophysics being used for qualitative purposes only. This is because (1) geophysics requires models that relate geophysical signals to soil moisture...
