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.

Web-based Near-real Time Flood EViDEns for Lake Mainit

flood_evidensThe Phil-LiDAR 1.2.14 Team has developed a preliminary version of an application for flood extent visualization/inundation monitoring for Lake Mainit. Called the Web-based Near-real Time Flood Extent Visualization and Damage Estimations (Flood EViDEns), the app utilizes (at the moment) a 10-meter SAR DEM as source of topographic information. The concept behind the Lake Mainit Web-based Near-real Time Flood EViDEns is that lake water inundation extent can be generated by utilizing water surface elevation (WSE) data recorded by water level monitoring stations in combination with a DTM. Since the lake WSE is known, then we can find those areas within and in the vicinity of the lake whose elevations are equal to the lake WSE. These areas can be considered as inundated. Moreover, as lake WSE is constantly provided by monitoring stations, then it is possible to create and update in near-real time a map of lake water inundated areas.

The Google Map below reflects the initial output of the Lake Mainit Web-based Near-real Time Flood EViDEns. To know the date and time of inundation information, please click on the blue lines.

Satellite-based land-cover mapping of Cabadabaran, Mainit-Tubay and Tago River completed

The land-cover maps of Year 1 project areas namely Cabadbaran, Mainit-Tubay and Tago River Basins have been completed. The maps were generated through analysis of year 2014 Landsat 7 ETM+ and Landsat 8 OLI satellite images.

Information on the type and distribution of land-cover within a river basin is an important requirement for flood model development. Land-cover information is utilized in two aspects: (i) to compute how runoff is generated in the upstream watersheds during a rainfall event, and (ii) to determine how smooth or rough the surfaces are within the river basin which is necessary in quantifying the propagation speed and volume of flooding in the floodplains.

Phil-LiDAR 1.B.14 reviews recent accomplishments, conducts planning workshop

The Phil-LiDAR 1.2.14 Project Team conducted an out-of-town workshop last May 5-6, 2014 at Villa Paraiso Resort in Mambajao, Camiguin province.
