Assessment of thermal UAV to measure beach surface moisture

Surface Moisture content is the amount of water held in the top layer of soil; it is important to aeolian geomorphology and dune development as water acts as an adhesive increasing the force of wind required to transport the sand. Accurate measurement of surface moisture content can help to determine at what point sand transport may begin to occur.
Measuring surface moisture content has long been studied using a variety of Remote Sensing techniques including aerial, pole-mounted, or handheld cameras using both traditional RBG and Infrared imagery. However, never before have scientists attempted to measure surface moisture content with an unmanned aerial vehicle (UAV). UAV’s have been used in variety of other forms of environmental research, however not for measuring surface moisture content.
UAVs have many potential advantages compared to the other surface moisture measurement methods. They are cheaper than aerial mounted cameras, can cover a larger spatial area than both pole-mounted and handheld cameras, and temporal measurements can be controlled by the researcher. Despite UAVs many perceived advantages, the accuracy and viability as a measurement method must be verified.
