Abstract

Abstract: Various kinds of buildings in civil engineering require careful planning. For example, in the planning of a water building needed a method to calculate the design flood discharge before starting to plan the dimensions of the building to meet the effectiveness of the water structure. Design flood discharge can be determined using several hydrograph methods that have been used in water building planning in Indonesia. One of the popular hydrograph method used is the Nakayasu Synthetic Unit Hydrograph method. In this case, the design flood discharge is located in the Garang watershed, precisely in Semarang City, province of Central Java, using rainfall data for the past 16 years. Hydrological analysis is carried out first before determining the design flood discharge with a return period of 2, 5, 10, 25, and 50 years. The results of the design flood discharge using Nakayasu method respectively were 305,522 m3/s, 390,742 m3/s, 447,783 m3/s, 520,560 m3/s, and 574,912 m3/s.

Abstract

The study of the maximum water level control of the Jatibarang reservoir is to avoid the possibility of overtopping due to flooding after 100 years return period, therefore it is necessary to take into account the changes in land use, which were once shrubs turned into settlements. Changes in land use result in an increase in the drainage coefficient which results in an increase in surface runoff so that the flood discharge in the river becomes even greater. Jatibarang Dam in Semarang at the time of planning was still designed to use flood discharge return period of Q 50 years; whereas the water structure has included a hazard level classification, so flood safety standards should have been used return period of the Q 100 years. The aims of this study are (1) to analyze the maximum CWL value in the main spillway of the Jatibarang dam based on the analysis of flooding due to Q 100 years; and (2) comparing the maximum CWL value of the main overflow dam Jatibarang results of planning using Q 50 years with the maximum CWL value of the main overflow dam due to flood discharge Q 100 years.This type of research was a survey. Data collection methods used were observation and documentation. The observation method was used to determine the coordinates of the dam spillway, which was then used to make a Jatibarang dam spillway watershed map and directly observe the Jatibarang dam spillway construction. The documentation method was used to collect rainfall data.The inflow flood hydrograph for a 100 year return period is 1838.84 m3/s, while the outflow is 227.57 m3/s, thus the Jatibarang reservoir can accommodate or store flood discharge of 1611.27 m3/s. The maximum elevation of the Jatibarang dam spillway is +155.3. The flood routing results show that the highest elevation is +154.05 at ten time. Comparison between the highest elevation of Q 100 years flood routing results which is equal to +154.05 is lower when compared to the maximum elevation of the Jatibarang dam spillway which is equal to +155.3; so that the main spillway elevation is still able to overcome of Q 100 years. Thus the Jatibarang dam spillway is still safe against the highest elevation of flood Q 100 years.
