Peak Flood

One of the bridge crossing of the Ciliwung River at the upstream side entered DKI-Jakarta area is MT. Haryono Bridge, where the bridge has the heavy and jam traffics. Every rainy season, water level of Ciliwung River flood always increase, where the peak point of the flood was occured on February in 2007, the water level exceeded the bridge deck level.  Therefore, it would be necessary to determine a height standard of the bridge deck of MT.Haryono bridge against to the water level of Ciliwung River when the peak flood occured, the existing of the elevation at the below of the bridge deck is + 18.50 meter and the elevation above the bridge deck is + 19.50 meter. Hydrology analysis using Log Pearson type III performed to determine the data of average daily and yearly rainfall around of catchment area of Ciliwung River with using the water level control point near Kalibata Bridge and the flood hydrograf was calculated using synthetic hydrograph method from Nakayasu. Hydraulic analysis utilized the of HEC-RAS software (4.1) using the maximum value of hydrograph unit and consists of two simulations, where the first is simulation of calibration model of Ciliwung River at the upstream side based on the flood occured on February 04th 2007 (called as Q2007) and the second simulation using some scenarios for some return period of 2, 5, 10, 20,50, 100 years. Every result of both simulations generates the height of bridge deck from the water level of flood according to the exsisting requirements. From these results, it could be determined the elevation of bridge deck for return period of flood for the peak flood 2007 and for 2, 5, 10, 20, 50, 100 yearly, and, such as +19.50, +20.50, +21.00,  +21.10, +21.80, + 22.10 dan 22.00 meter.

Jambi River is one of the rivers located in the Muaro Jambi Temple Complex Area, Muaro Jambi Regency, Jambi Province. Muaro Jambi Temple is one of the tourist attractions in Jambi Province. This study aims to find the capacity of Jambi River tested by planned flood discharge utilizing (synthetic unit hydrograph) HSS Nakayasu method for a return period of two, five, ten, twenty-five, fifty and hundred years. HEC-RAS software used to analyse the water level in the Jambi River towards the flood potential that causes the submerging of the Kedaton Temple building. This research used the log Pearson type III method to calculate the planned rain return period and used the Nakayasu synthetic unit method to calculate the planned flood discharge. The analysis showed that the Jambi River could not load the flood discharge in the five, ten, twenty-five, fifty, and one hundred years return period at several measurement points: river sta-1, river sta-2 and river sta-5. The floodwater level did not cause the Kedaton Temple building to be flooded from the simulation result

The Relationship

Water demand should be balance with water availability. The population of Bogor City was increased every year, so that water demand become increased. Currently, Government of Bogor City only utilizes the Cisadane river as a source for drinking water, but Bogor City has 2 rivers there are Cisadane river and Ciliwung river. So, Ciliwung river can be solution for this problem. Water discharge and rainfall influence water availability.  Distribution log pearson type 3 used to predict the water discharge and rainfall and linier regression analyzed the relationship between water discharge (dependent variable) with rainfall as X1 and water level as X2 (independent variable). The result of distribution log pearson type 3 every return period 2, 5, 10, 25, dan 50 years is water discharge and rainfall were increased. Average increase of water discharge every return period is 1.6 m3/s and average increase of rainfall every return period is 251 mm. Partially, water discharge influenced by water level 97.7% and 2% by rainfall. But,  = 0.000 <  = 0.05. it is mean rainfall and water level cannot be ignored because it can influence water discharge with regression model  = -3.01 + 0.000 X1 + 0.202 X2.

Abstract: Belawan River Basin is one of the watershed, which currently change the land use because of the increasing population and industrial development. Rainfall with high intensity can cause rapid runoff, causing flood around the plains of the river cross section. The purpose of this research is to determine the flood water level of Belawan Watershed and flood discharge return period. Scope of activity in this research is analyzing daily rainfall Belawan watershed with the flood-discharge return period. Scope of activity in this research is analyzing maximum daily rainfall Belawan Watershed, and simulating flood water level with HECRAS. The result of the study shows that the potency of Belawan watershed flood water level is caused by flood discharge at 25 to 100 years especially in the middle to downstream of river cross section that is between 0.7 m and 3.3 m. Keywords: Flood Discharge, Flood Level, Belawan Watershed, Software HECRAS. Abstrak: Daerah Aliran Sungai Belawan adalah salah satu DAS yang pada saat ini mengalami perubahan tata guna lahan seiring bertambahnya jumlah penduduk dan perkembangan industri. Curah hujan yang tinggi dapat mengakibatkan limpasan sehingga menimbulkan tinggi muka air banjir di sekitar dataran penampang sungai. Tujuan dari penelitian ini adalah untuk mensimulasi tinggi muka air banjir DAS Belawan dengan debit banjir periode kala ulangnya. Lingkup kegiatan dalam penelitian ini yaitu menganalisa curah hujan harian maksimum rata-rata DAS Belawan dan menganalisa debit banjir kala ulang 2 sampai dengan 100 tahun, mensimulasi tinggi muka air banjir dengan HECRAS.
