The CLSU Phil-LiDAR 1 together with the Data Validation Bathymetric Component (DVBC) of UPDiliman Phil-LiDAR 1 conducted a joint bathymetric survey from July 22, 2016 to August 3, 2016 in Morong and Talisay Rivers in Bataan. Bathymetry is the measurement of water depth at various places in a large body of water. Bathymetric data will be processed to generate the riverbed topography or the terrain of river. The data are important to create hydrodynamic models such as flood depth and flood hazard map. Three of the CLSU Phil-LiDAR 1 researchers namely: Engr. Jose T. Gavino, Engr. Bennidict P. Pueyo and Mr. Christopher R. Genaro joined the bathymetric activity.
