Abstract

Bendung merupakan suatu bangunan sungai yang mempunyai peranan penting bagi kehidupan. Dalam pembangunan suatu bendung, harus memperhatikan keseimbangan ekosistem yang ada agar ekosistem tetap terjaga, salah satunya dengan cara membangun bangunan pelengkap sungai berupa tangga ikan (fishway). Untuk mengetahui efisiensi bentuk fishway yang dapat dibangun, pada penelitian ini dilakukan percobaan dengan menggunakan ikan sidat (Anguilla bicolor, sp) yang kemudian akan dilakukan pengujian pada alat fishway dengan kemiringan dan dua tipe pijakan yang berbeda, yaitu tangga sekat dan vertical pool passes yang kemudian akan dibandingkan dengan tipe pijakan pipa PVC yang telah dilakukan pada penelitian sebelumnya. Dari penelitian yang telah dilakukan, terjadi penurunan rasio aktivitas seiring bertambahnya sudut kemiringan pada fishway dan diperoleh nilai rasio tertinggi pada percobaan dengan sudut kemiringan 25° dengan rasio sebesar 4,40 untuk tipe pijakan tangga sekat dan 3,72 untuk tipe pijakan vertical pool passes. Sedangkan jika dibandingkan antara tipe pijakan tangga sekat, vertical pool passes dan pipa PVC diperoleh nilai rasio tertinggi yaitu pada penggunaan pipa PVC 0,5 inch dengan rasio sebesar 4,50.

Abstract

The Way Besai River is located in Sumber Jaya District, West Lampung Regency. River discharge is an indicator of watershed function in transforming rain into stream flow. River discharge is generally presented by hydrograph. There are two methods to derive unit hydrograph, i. e. Measured Unit Hydrograph method (HST) and Synthetic Unit Hydrograph method (HSS). Synthetic Unit Hydrograph is used if the watershed does not have sufficient hydrometry data for calculating flood discharge. The purpose of this study is to analyze Synthetic Unit Hydrograph Gama I, Synthetic Unit Hydrograph SCS (HEC-HMS), and measured unit hydrograph for Way Besai River. The method used in this study includes Synthetic Unit Hydrograph Gama I, Synthetic Unit Hydrograph SCS (HEC-HMS), and Measured Unit Hydrograph. The results of this study show that Unit Hydrograph derived from Synthetic Unit Hydrograph SCS (HEC-HMS) is better than the result derived from Synthetic Unit Hydrograph Gama I based on peak discharge, peak time, base time and base flow values. Keywords: Watershed, Discharge, Synthetic Unit Hydrograph, Measured Hydrograph Unit, SCS (HEC-HMS), Gama I.

Abstract

The calculation is done using the rainfall data obtained from BMKG Kotabumi North Lampung,from 1998 until 2011 with time increment in minutes. The Log Pearson III method is used to findthe design rainfall with return period 2 years, 5 years and 10 years. Then the result isimplemented in the Intensity-duration-frequency (IDF) curves. Time of concentration is linked intothe IDF curves to determine rainfall intensity. Based on the calculated rainfall intensity, thedesign discharge for each return period can be calculated using the rational method.The values of design discharge are then inputted as upstream boundary condition in HEC-RAS.Model output are presented in cross and long section to determine at which return period thedrainage capacity is overflowed. Simulation using HEC-RAS were also done to determine thechannel capacity.Based on the results of this research, it can be concluded that rainfall intensities are 52,6918mm/hour, 65,7820 mm/hour and 75,9032 mm/hour, for 2, 5, an 10 year return period respectively.The capacity of the drainage channel is 2.02 m 3 /hour and is expected to be exceeded on 5 yearsreturn period.Key words : Intensity, Rasioanal method, HEC-RAS, capacity

Abstract

Flood events often occur in Indonesia so that quite a lot of people researched about the movement of floods and flood monitoring in the Watershed. The location of the study was carried out by the Way Sekampung river in Way Kunyir located in the Pringsewu district, Lampung province and is located downstream of the Batutegi dam. Flood tracing is intended to analyze the chances of a flood in the form of a flood hydrograph with or without using the Routing method and find out the results of some Routing methods in the watershed. The Routing method used in this study is Lag, Lag and K and Muskingum. The HEC-HMS modeling results state that peak discharge data when without Routing is greater than entering the Routing parameter. This is because entering the Routing parameter in modeling is very influential at peak times so that it affects the peak discharge at the watershed outlet. As a result of Muskingum Routing, the peak discharge is lower than before entering the flow routing, this is due to the occurrence of reservoirs along the river so that the peak discharge becomes lower than without Routing. The results of Lag Routing and Lag and K Routing are peak discharge decreased compared to before entering the Routing parameter. what should have happened to the peak discharge with Routing and without Routing remains the same, however, only peak discharge tranlations occur and there is travel time. This happens because there is no debit data at the station being reviewed so it uses rain data instead of HEC-HMS modeling.
