The 7th CREATE Congress was held with the theme CREATE: Committed to a Resilient And Technologically-Empowered Society (or CREATE CREATES). It was aimed to provide Engineering, Architecture and Technology Educators updates in the topics of Disaster Risk Reduction thru the application of RS/GIS; to provide avenue for the students to showcase and present their projects and researches; and to provide students and faculty with the latest trend in Engineering, Architecture and Technology.

UPD Phil-LiDAR 1 DPPC visits CSU LiDAR 1

The Data Pre-Processing Component (DPPC) of the University of the Philippines-Diliman (UPD) Phil-LIDAR 1 project visited the CSU LiDAR 1 office last March 11-13, 2015. The visiting team was composed of Engr. Sarah Jane Samalburo, Chief Science Research Specialist; Engr. Gladys Mae Apat, Supervising Science Research Specialist; Engr. Harmond Santos, Senior Science Research Specialist; and Engr. Kechy Solidum, Senior Science Research Specialist.

Kechy Solidum (UP Phil-LiDAR 1 DPPC), Engr. Harmond Santos (DPPC), Engr. Sarah Jane Samalburo (DPPC), Engr. Gladys Mae Apat (DPPC), Engr. Meriam M. Santillan (CSU LiDAR 1 Project Leader), Engr. Jojene R. Santillan (CSU LiDAR 1 CSRS), Engr. Presley Carl Oconer (DPT), and Engr. Jesiree Servianco (DPT).

The purpose of the visit was to address and discuss existing LiDAR data processing issues and concerns encountered by CSU LiDAR 1’s Data Processing Team (DPT). The visit was very important considering that all LiDAR data being processed by the DPT (i.e., preliminary Digital Terrain Models – DTMs, Digital Surface Models – DSMs) all came from UPD DPPC which they generate through pre-processing of raw LiDAR datasets. These preliminary DTMs and DSMs are being edited and mosaicked by the DPT to produce geometrically accurate, calibrated and validated DTMs and DSMs. These final outputs are then utilized by the DPR or extraction of features (buildings, roads, bridges), and by the Flood Modeling Team (FMT) for flood model development. The UPD Phil-LiDAR 1 DPPC Team also presented how they do the LiDAR data pre-processing: from data download from the LIDAR sensor, georeferencing, LiDAR classification, and generation of preliminary DTMs and DSMs.

During the visit, several issues and concerns were discussed that includes coverage of available LiDAR data, status and progress of LiDAR DTM and DSM editing and mosaicking, technical problems encountered during editing and mosaicking, and DTM and DSM quality checking.

CSU LiDAR 1 now on its Year 2; conducts project orientations in Surigao del Sur

The Phil-LiDAR 1.2.14 Project of Caraga State University, also called the CSU LiDAR 1 project, is now on its second year of implementation. CSU LiDAR 1 is one of several projects under the “Phil-LiDAR-1. Hazard Mapping of the Philippines using LiDAR” program funded by the Philippine Council for Industry, Energy and Emerging Technology Research and Development – Department of Science and Technology (PCIEERD-DOST). Projects under this program are being implemented nationwide by several state universities and colleges (SUCs) and higher education institutions (HEIs). CSU LiDAR 1 in particular will generate flood hazard maps of the river basins and watershed of Caraga Region (except the Agusan River Basin which has been covered by the UP DREAM program).

This 2015, the project will cover the river basins of Tandag, Hubo-Otieza, Hinatuan, and Bislig, all in the province of Surigao del Sur. As its first major activity for the year, the CSU Phil LiDAR  1 Project conducted project orientation and courtesy visits to four (4) municipalities and two (2) cities of Surigao del Sur which are covered by the Year 2 river basins. The visits were conducted last January 28-29, 2015. On the 28th, the municipality of San Agustin and the city of Tandag were visited while the municipalities of Barobo, Tagbina, Hinatuan and the city of Bislig were visited on the following day.

During the conduct of the project orientation, the project team was able to meet the local government officials and staff of the Mayor’s office, local planning and development office and the disaster risk reduction management office. The conduct of the activity also served as an avenue for the project team to request from the Municipal Mayors or representatives for a focal person whom the project members will be contacting if and when the project will be conducting a fieldwork within the city/municipality. Each municipality and city were provided with printed maps of Digital Surface Models (DSMs) as tokens of appreciation for welcoming and accommodating the project team.

Simulations of Flooding Due to ‘Agaton’ and ‘Seniang’ in Cabadbaran River

Preliminary and unvalidated 2D simulations of the January 2014 Typhoon Agaton and December 2014 Typhoon Seniang flood events in Cabadbaran River, Agusan del Norte, Philippines. The purpose of these simulations is to provide preliminary visualizations of the differences in the magnitude and extent of flooding during the two typhoons.

The simulation was generated using the Environmental Fluid Dynamics Code or EFDC, with inflow hydrographs computed using HEC HMS and tidal data as boundary conditions. The 2D model utilized LiDAR-derived DTM provided by UP DREAM/Phil-LiDAR Data Preprocessing Team of UP Diliman. The river bed topography/bathymetry of Cabadbaran River is not yet integrated into the DTM used during the simulation. The model simulations will be updated once river bed topography/bathymetry of Cabadbaran River is available.

PCIEERD visits LiDAR 1.2.14, conducts project monitoring

On December 18, 2014, the Phil-LIDAR 1.2.14 project office was visited by representatives from DOST PCIEERD headed by Engr. Nelson Beniabon, Chief of Emerging Technology Development Division (ETDD) and Ms. Sonia P. Cabangon, Chief of Finance and Administrative Division (FAD). The visit was part of PCIEERD’s project monitoring activities. The team inspected the facilities and equipment purchased by the project, as well as financial documents. During the visit, the Project Leader, Engr. Meriam M. Santillan, reported to the PCIEERD team not only the latest progress and accomplishments of the project, but also important project concerns such as the problems and difficulties encountered.

Field testing of water level loggers and 2D velocity meters

Last October 22, 2014, the Phil-LiDAR 1.2.14 team conducted a field testing of water level loggers and 2D velocity meters that were recently purchased by the project in Taguibo River which is approximately 4 kilometers from CSU campus.

The said sensors will be utilized for long term measurements of water level and velocity in specific locations along the Cabadbaran, Mainit-Tubay, and Tago Rivers. The long term measurements combined with cross-section data at the deployment stations will be processed to compute discharge hydrographs. These hydrographs together with rainfall data will then be utilized to calibrate and validate the HEC HMS-based hydrologic models of the Year 1 river basins. The HEC HMS models consist a major component of the flood models that will be produced by the project.
