Upstream part of Ciliwung watershed spread from Pangrango Mountain region to <br /> <br /> the Katulampa’s weir that serves as to protect and buffer main watersheds that <br /> <br /> affect the potential flooding in Jakarta . Meteorological factors associated with the <br /> <br /> river discharge, water level and rainfall intensity. River discharge used to <br /> <br /> determine the occurrence of floods and flood mitigation process. For mitigation <br /> <br /> and discharge data processing, the data required as height of water that can be <br /> <br /> obtained at the actual time. Discharge measurements manually by the operator is <br /> <br /> particularly vulnerable to errors in reading the data so it can produce a fatal error <br /> <br /> when the data recorded is not the actual data . Therefore, we need a water level <br /> <br /> gauges that can take practical data and can transmit data at any time. <br /> <br /> Measurements carried out in the Katulampa weir area. Water level data is <br /> <br /> converted to discharge data using manning method. Rainfall data is converted to <br /> <br /> discharge data using HEC HMS models and overall data will be compared to <br /> <br /> obtained correlation and RMSE between data. Overflow water calculated by <br /> <br /> Muskingum method. <br /> <br /> Based on discharge results of the HEC HMS models with rainfall , land use and <br /> <br /> soil type as input data are compared with the calculated discharge with manning <br /> <br /> method using instrumentation tool and also weir station discharge data. Land use <br /> <br /> and soil type which is dominated with latosols influence the amount of water that <br /> <br /> entering the river caused by the rain. All flow data from devices processed by the <br /> <br /> manning method compared with data result on discharge data from weir station <br /> <br /> and have a good correlation result. In this study, a high correlation between the <br /> <br /> data of water equipment with water height data from weir station have 0.89 in the <br /> <br /> result, it states that the automatic water level measurements sensor is feasible <br /> <br /> sensor to use while calibration field done, because it has the same pattern in the <br /> <br /> movement of data, whereas the water level RMSE value of AWLR 25,9cm states <br /> <br /> that the sensor still need to calibrate to makes the best accuracy of the data so the <br /> <br /> sensor to be more fit for use as a counter height of water in the field by <br /> <br /> performing a calculation field as needed .
