Project Summary: The nature of the water source commonly determines the planning, design, and operation of the collection, purification, transmission, and distribution works. The two major sources used to supply community and industrial needs are referred to as surface water and groundwater. Fena Lake within Talofofo Watershed is one of major drinking water resources for Guam. Thus, information on hydrological characteristics of both Talofofo Watershed and Ugum Watershed is essential to manage the water resources. The overall objective of this study is to provide better understanding of these watersheds with soil erosion and nutrient transportation dynamics in time and space. The proposed project is based on a combination of experimental and numerical approaches: i) collection of water quality parameters and ii) development of a watershed management model based on the Soil and Water Assessment Tool (SWAT) for estimating daily streamflow and the concentrations of suspended solids and nutrients from the river system. By the limited timeframes, the water quality parameters will be collected through the Phase 1.
