DOST conducts river profiling research


The Caraga State University (CSU) Phil LiDAR-1 research team, using various equipment, takes the profile of Cabadbaran River in Agusan del Norte. One tool used here is the Acoustic Doppler Current Profiler, the gadget that looks like a small boat carried by a research team member, which measures how fast water is moving across an entire water column. Anchored to the seafloor, it can measure current speed not just at the bottom but also at equal intervals all the way up to the surface. The information gathered by this profiler is beamed by a bluetooth antenna to a laptop that records the data. According to Meriam M. Santillan, project leader based at CSU, profiling a river enables the creation of 3D flood hazard maps that can help prepare communities during weather disturbances that may trigger floods. CSU Phil LiDAR-1 of the Nationwide Phil LiDAR 1 Program is a component of the Department of Science and Technology’s Project NOAH.
