Abstract

The application of the polder system for flood control in DKI Jakarta has become a must for coastal areas, especially with the construction of sea dikes along the coast of Jakarta as a solution to anticipate tidal flooding. One thing to consider when using a polder system in flood control is how much pump capacity and reservoir are needed. To answer this quetions, a hydrological analysis has been carried out with several method approaches, starting from determining the rainfall design in the form of a depth duration frequency curve in 1 hour to 48 hours, and then applied area reduction factor (ARF) to corrected rainfall design. Natural Resources Conservation Service (NRCS) method are uses to calculated runoff or effective rainfall and then with the unit hydrograph by time area method to produce a runoff hydrograph. Based on this approach, the Sentiong Polder plan has been carried out with the result that the required pump capacity for a 25-year return period is 32 m3/s and 50 m3/s for a 100-year return period with a storage capacity used of 1,507,500 m3. If you want to reduce the pump capacity, it is necessary to increase the storage capacity.

Abstract

The empirical methods of intensity duration frequency are most often used with limited data. Its information is needed to design a drainage system. This study aims to obtain the best empirical method that can describe the curve of intensity duration frequency in Bekasi. These methods use the Mononobe, van Breen, and Bell methods and are then calibrated with intensity duration frequency curves derived from short-duration data (observation). The result shows that no empirical techniques best fit the words. However, the Mononobe method has fewer results than the Bell, van Breen, and observations. When the three practical methods were compared with the comments, the Bell method was the most suitable approach for determining the rain intensity for a return period of under five years. In contrast, the van Breen method was for a return period of more than five years.
