This research aimed to generate watershed recharge zone with weighted value, and determine the effect of rainfall factor for watershed recharge zone assessment. Determining watershed recharge zone is one of essential part in integrated water resources management. Watershed recharge zone is used for preventing land use conversion that mostly happened in urban area watershed. In Indonesia, Ministry of public works and housing was determined recharge zone spatial criteria as stated in Ministry regulation number 10/2015, consist of following factors: rainfall, slope, land use and soil texture and use weighted method to generate recharge zone. The selection of Cisadane Watershed for case study based on watershed varying characteristics and was determined to be one of priority watershed in Indonesia. Each factors (rainfall, slope, landuse and soil texture) will be further analysed with spatial classification as a grid with 2 modelling scheme: modelling with slope, land use and soil texture as internal factor and modelling with rainfall as external factor. These scheme result rainfall is sensitive factor to generate watershed recharge zone and increase potential water recharge from domination of ‘average-good’ to ‘moderate-good’ in Cisadane Watershed. This research is a desk study and further can be developed with ground test validation.
