ADVANCING STREAM TEMPERATURE MODELING USING TOPO-BATHYMETRY LIDAR AND THERMAL INFRARED DATA
Airborne thermal infrared (TIR) and topographic lidar are essential data sources for studying stream temperature regimes and restoration designs. The combination of these technologies provides valuable high-resolution, spatially explicit information to identify stream thermal refugia, cold/warm inflows, riparian vegetation, above-water terrain, and the associated parameters for solar loading and shading. However, submerged channel morphology has remained reliant on extensive on-site fieldwork efforts to augment remote sensing data. Such field-based survey efforts, to collect channel transects for example, are time-consuming, costly, and limited to accessible sites along the stream yielding sporadic, low resolution data. Recent developments in lidar technology have introduced a new generation of topo-bathymetric sensors, which combines near-infrared (NIR) and green wavelength laser technology (green wavelength laser penetrates the water column in shallow water environments). This new technology not only reduces the required fieldwork, but also provides high-resolution maps of terrestrial and in-stream digital elevation models. In turn, the need for field-collected channel transect are theoretically eliminated. In this presentation, Quantum Spatial will showcase examples of utilizing topo-bathymetry lidar data in stream temperature models, highlighting the opportunities to improve our understanding of the processes dictating in-stream conditions.
