9. STORM SURGE
SIMULATION
The JMA Storm Surge Model is a numerical model
developed by the Japan Meteorological Agency (JMA)
to simulate and predict storm surges
mainly caused by tropical cyclones.
10. Parameters for Storm Surge Modeling
Storm track
Maximum wind speed,
Central atmospheric pressure,
Bathymetry.
13. NOAA Comet Program Difference between a storm surge and storm tide.
NOAA Comet Program difference between a surge on a steep seafloor and gently-sloping seafloor.
19. STRUCTURALLYCONTROLLED
LANSLIDE SIMULATION
Coltop3D – simulates a 3D model of the DEM showing the dip and dip direction
of its different discontinuity sets.
Matterocking - computes and estimates the locations where rock instabilities
can occur based on the identified discontinuity sets that allow sliding

Supertyphoon Yolanda (international name Haiyan) made aninitial landfall in Guian, Eastern Samar then made its second landfall in Tacloban, Leyte at 0700H on November 7.It left a trail of devastation that resulted in 4,011 persons dead, 18,557 injured and 1,602 missing. It also inflicted a total damage of nearly PhP12.5 billion with PhP1.9 billion for infrastructures and PhP10.5 billion foragriculture NDRRMC.

The poorly drained soils in Leyte are found in the following areas: low lying areas around Palo,Tanauan, and Alangalang (Pawing Series);and around the municipality of Palo, extending to the inner regions at the foot of the central Cordillera near Jaro and DagamiAlangalang and Barugo on the north and in Abuyog on the south (Palo Series). Pawing and Palo series developed from recent alluvial deposits and both have minimal soil prole development.The moderately drained at lowland soils belong to the soil series of San Manuel, Umingan, Dagami, Mandawe, and Bantog series. These soils are found in the following areas: Babatngon, Palompon, Hilongos; alluvial soil formation on Western Leyte from Ormoc to Baybay; in the municipality of Dagami; along the Hilongos and Bangerahan rivers; and in the municipality of Villaba. These soils developed from alluvial deposits, show moderate soil prole development, and have level to nearly level topography. These soils are mostly cultivated for agriculture.
The storm track is the path being followed by the center of the tropical cyclone.Wind speed is the rate of change of horizontal air in a given moment or amount of time.Bathymetry is the study of the oor beds of bodies of water or is simply described as the depth of ocean relative to the sea level.
