TOPOGRAPHY
Cavite is divided into four (4) physiographical areas, namely:
The lowest lowland area, lowland area, the central hilly area and the upland mountainous area. The lowest lowland area is the coastal plain in particular. These areas have extremely low ground level of EL. 0m to EL. 2m compared to the high tide level of about EL. 0.8m from the Mean Sea Level (MSL). These are the municipalities of Bacoor, Kawit, Noveleta and Rosario.
The lowland area consists of the coastal and alluvial plains. These areas have flat ground slope of less than 0.5% and low ground elevation of EL. 2m to EL. 30m. The alluvial plain can be found in the municipality of Imus and southern part of General Trias. Into these municipalities forms the transition area between the coastal plain and the central hilly area. It also covers some areas of Bacoor, Kawit, Noveleta, Rosario and Tanza.
The third topography type is the central hilly area, generally found on the mountain foot slope. It forms the rolling tuffaceous plateau. This topography includes steep hills, ridges and elevated inland valley. The plateau is characterized with ground elevation ranging from 30m to nearly 400m. Its ground slope ranges from 0.5 to 2%. The city of Trece Martires and the municipalities of Dasmariñas, Indang and Silang have this kind of topography.
The last topography type is upland mountainous area, found in Amadeo and Tagaytay City. They are situated at a very high elevation above EL. 400m with slopes of more than 2%. The Tagaytay ridge has a peak elevation of 650m.
