Recharge <br>are difficult to measure directly and the field-based methods are time consuming, expensive, and require large <br>number of skilled manpower. Application of remote sensing and geographical information system (GIS) has <br>wide application and good result in delineating recharge zone and various other fields. The present study aim <br>to delineating potential recharge zone using GIS based on Indonesia Regulation with comparison of water <br>balance modelling (NRECA and FJ Mock) in Cisadane watershed Indonesia. Water balance model is used for <br>generating rainfall data into monthly discharge (base flow and direct runoff) with validation of 3 discharge <br>station (Genteng, Batubeulah and Serpong) as representative of upstream, middle and downstream of Cisadane <br>watershed. Rainfall is a dynamic and sensitive factor for generating potential recharge zone, there is a <br>significant changing of potential recharge zone between using 3 parameters and 4 parameters, potential <br>recharge zone can increase or decrease based on annual rainfall. The accuracy of NRECA and FJ Mock model <br>and result fairly good validation with acceptable NSE (0.52-0.61) and R values (0.76-0.87). Potential recharge <br>zone map using 4 parameters (land use, slope, soil and rainfall) is suitable with the results of baseflow <br>percentage of NRECA and FJ Mock model. Cisadane watershed is dominated by medium (33.62%) to high <br>potential recharge (55.49%)</p> ER -
