CABRAL WEENJEL P. and HERRERA JHON LAURENCE B. Delineation of Cafias Watershed in Cavite, Philippines Using Geographic Information System and Remote Sensing with Field Validation. Undergraduate Thesis. Bachelor of Science in Environmental Science. Cavite State University, Indang, Cavite. April 2016. Adviser: For. Junser P. Magpantay.
The study was conducted to delineate Callas River Watershed using Geographic Information System and Remote Sensing from July 2015 to February 2016. Specifically it aimed to: 1. delineate Carias River Watershed using Digital Elevation Model and Arc tool in ArcMap 10.2.1; 2. conduct a field survey in different areas within Carias River Watershed to validate its boundaries and river network; and, 3. describe the physical attributes of Callas River Watershed in terms of area, geographic location, drainage system, and existing land use. Watershed delineation was done in ArcMap 10.2.1 to determine Callas River Watershed using the Shuttle Radar Topography Mission — Digital Elevation Model (SRTM-DEM). The same data was also used to describe its slope, aspect, elevation APO model, land use map and total land area. The existing land use of Carias River Watershed was determined using a 2014 LandS at Image from the United State Geological Survey (USGS). Political boundary map was overlaid in order to identify the municipalities and barangays within the Canas River Watershed. A handheld GPS (Ashtec Mobile Mapper Field 10) was used to collect GPS coordinates to validate the river networks of Carias River Watershed. GPS coordinates were collected randomly within the watershed close to the physical river networks that are accessible. Watershed boundaries were validated by collecting GPS coordinates randomly in the road networks. Catias River Watershed runs from south to north before draining to Manila Bay. The headwaters of Callas River Watershed are found in Tagaytay. The river network passes through the municipalities of Indang and Amadeo. It continues down to Trece Martirez, General Trias and Tanza. It exits in the municipality of Rosario Cavite. The watershed traversed seven municipalities/cities within the Province of Cavite. These municipalities/cities are Rosario, Tanza, General Trias, Trece Martires, Amadeo, Indang, and Tagaytay. Within these seven municipalities/cities are 95 barangays located inside Callas River Watershed. The watershed has a total land area of 11,075 hectares with elevation ranging from 0 to 713 masl. The lowest slope of the watershed was 0-3 degrees and its calculated highest slope was 35-46 degrees. The aspect map of the Catias River Watershed was delineated using ArcMap 10.2.1 and has a mean value of 184.61.
