Abstract
Guam is a strategic location for the United States of America, which is located in the western Pacific. Guam’s economy is mainly supported by tourism and military related activities. Because of buildup activities and increasing population of tourists in the following few years, much pressure has been imposed on water resources and water quality in Guam. With about 5,000 marines relocated to Guam from Okinawa in the next few years, the Finegayan area will be a concerned area for buildup activities. Therefore, the study area for the project is located in the Finegayan area, and the research concentrates on application of LiDAR data to figure out sinkholes in the Finegayan area, and application of GIS in evaluating salinity levels from drinking wells, and locating wells with problems with salinity in the study area. More concerns are focused on relationship between sinkholes and salinity, and whether sinkholes affect salinity levels in the study area.
Highlights
Guam, an unincorporated U.S territory in the western Pacific, is the largest and southernmost island in the Mariana Islands chain
Since around 5,000 marines will be relocated to Guam, the Finegayan area in the few years, it’s very important to evaluate whether relocation of the marines and their dependents, and related activities will affect the quantity and quality of the water resources, especially groundwater resources
This research mainly focuses on how to use LiDAR data to figure out sinkholes in the Finegayan area, and application of GIS in evaluating salinity levels from drinking/monitoring wells, and locating wells with problems with salinity in the study area
Summary
An unincorporated U.S territory in the western Pacific, is the largest (about 541.3 km2) and southernmost island in the Mariana Islands chain. Since around 5,000 marines will be relocated to Guam, the Finegayan area in the few years, it’s very important to evaluate whether relocation of the marines and their dependents, and related activities will affect the quantity and quality of the water resources, especially groundwater resources. Some recent research on impacts of human induced activities on water quality and historical evaluation of the factors contributing to changes of groundwater salinity in the Northern Guam Lens Aquifer are discussed by Wen [5] and Simard et al [6] respectively. This is no profound research on relationship between. Findings from the project will help local and federal government agencies, and other interested parties in better understanding and management of the Finegayan Area, and will facilitate buildup activities in the area
