Remote sensing of the earth system provides information about land surfaces, water bodies and their corresponding ecosystems. Infrared Thermal imaging has been proven as a highly reliable source of gather important information that cannot be seen easily by the naked human eye. Ground-penetrating radars give us water table depth and information about water levels based on change in the dielectric constant of overlying material. Spatial patters of stream temperature at the ground scale are relevant towards issues related to water quality. The objective of this study was to conduct experiments to measure and report the data collected using long wave 7 – 14 μm IR thermographs and 500 MHz ground-penetrating radar signals to model stream temperatures across the banks of Spring Creek, Centre County, Pennsylvania and the properties thereof. Multiple data sets were collected in the field and experiments were carried out to measure the temperature profiles between the two banks and soil moisture along the banks of Spring Creek. Pixelated models of radar signals along measured distances and infrared images were created with calculations of statistical timelines of temperature and soil moisture variation. This thesis highlights the methodologies, the instrumentation, the data analysis and statistical techniques used to discusses the results obtained, along with the inferences that can be drawn based on this study.
