Remote sensing technologies, involving drone and satellite imagery, have recently begun to be used in hydrologic research with various applications. The technology is relatively easy to obtain, is noninvasive, and helps minimize cost, access, and safety concerns related to the study of wetlands. The thermal and multispectral imagery can provide unique datasets that expand understanding into groundwater and surface water interactions. As part of this project, we are exploring remote sensing applications within the hydrology of wetlands surrounding Utah Lake, a large freshwater lake within Utah Valley. The project has involved the collection of thermal and multispectral drone imagery from 2021 to 2023. Thermal imagery collected in these areas has assisted in the determining of hot and cold spring locations and how these springs have shifted due to changes in groundwater levels and lake levels. In addition, this imagery has shown how physical anthropogenic influences have also impacted the location and stream channels associated with these springs. Multispectral imagery is used to understand the health of phreatophytes near the lake during dry and wet years to be used as an indicator for groundwater level changes. Even though much of the data is still preliminary and part of a long-term study these remote sensing technologies are already showing how these groundwater systems adapt to seasonal and anthropogenic changes.
