Abstract

Spatial information about the water availability in a region is very important in the management of sustainable water resources. Geographic information systems allows spatial information about water availability in watersheds to be assessed and monitored over time and within a predefined unit of space. This paper describes the application of GIS to assess the water availability and water demands spatially in the Cianten watershed, Bogor District, West Java. The availability of water for each sub-watershed was assessed using the water balance equation. Rainfall and temperature data for the 2007-2016 period, data of elevation, slope, soil type and land use for research area were used to calculate the water availabiliy, both annual and dry season. While the data on population size and land use were used to calculate water demands (domestic and non-domestic) for each sub-watershed based on the standards issued by the Ministry of Public Works and Agriculture. The analysis results using GIS platform shows a spatial variation of annual water availability and dry season. The water availability ranges from 9266 m3 / ha to 15,991 m3 / ha, while the dry season ranges from 2285 m3/ha to 4147 m3 / ha. Comparing water availability and water demands show that during the dry season most subwatersheds in the study area experienced a high to low water deficit.
