Analysis of potential water availability of the Baumata spring protected area in Baumata Village, Taebenu District, Kupang Regency, Indonesia

Abstract

Baumata water resources are subsurface water resources that come out as springs naturally, which are continuously used to meet the needs of clean water/raw water, industry/companies, and food crop agriculture. Changes in land use of protected areas are one of the factors that affect the discharge conditions of the availability of natural available Baumata spring water resources. This research uses the existing Water Balance Hydrological Model package for the rain to surface run off and subsurface flows (springs). The Hydrological Model Package used in the research to be carried out is the Mock Hydrological Model. The research variable is the availability of water resources for the land use of the Baumata spring protected area. Variables of availability of water resources include data: climate, rain. Baumata spring discharge and characteristics of protected areas to evaluate the potential availability of existing water resources. The results showed that the availability of Baumata spring is continuous because the flow is steady. Utilization of Baumata spring for the raw water needs of the local community AURI PDAM Mineral water, for agriculture/ plantation, for PT Semen and Shipping. The continuity of availability is strongly supported by the potential of natural protected areas that exist in response to rain events/events on the natural protected areas .
