Abstract

The purpose of this writing is to determine the handling of seepage and soil reinforcement required in the case study of the Margatiga Dam Project, East Lampung. Based on the results of geological investigations, the Margatiga Dam is composed of quarter-old rock layers with a fragment composition in the form of fine sand - gravel, with a hardness level of soft - hard and the need for foundation repairs. Based on the lithological conditions of the Margatiga Dam Extraction Gate foundation and the Spillway building which are composed of relatively deep and quite porous alluvial sand deposits, this causes the curtain grouting results to be ineffective, therefore it is necessary to change the design to control seepage from the Grouting Curtain to the boundary wall. Based on the simulation checks in the Plaxis Software for Seepage and Excavation Staging, processing was carried out using Secant Pile and Soldier Pile with a depth of 30 meters with a stretch of 140 m and overlapping with the left side of the Embankment Curtain Goruting. and the right side 5 m. PMT results in the field show that the maximum stress in the rock layer under the spillway foundation is 0.016 MPa and 0.630 MPa.

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

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.
