Abstract

Location studies Syamsudin Noor city is located in the city Banjarbaru, South Kalimantan. Poor drainage systems can cause waterlogging that may interfere with the function of airports. Is devoted to the planning of drainage channels to avoid puddles on the runway (runway).Rainfall data is processed by analyzing the frequency, which is the chosen distribution Log Pearson III. After it was made curved rainfall intensity using rational formula for some period of 5 years return period. Analyses were performed per Segmentst adjusted with drainage coefficient of each Segmentst to obtain a discharge plan.After analyzing the obtained Qmaks worth 5,101 m3 / s, the existing drainage channel is still able to accommodate the discharge plan. Then do the economic planning of drainage channels, obtained H = 1.4m and B = 1m for trunking and H = 0.8 m and B = 0.7m for the trapezoidal channel.Keywords: Syamsudin Noor Airport, runway, drainage

Abstract

Anjir Mulawarman is one of the canals in Banjarmasin. Anjir Mulawarman has a geometric shape that is straight with the street on both sides and riverbanks form gravity retaining wall. However, when the tide is still some places such as houses and streets that were around the riverbanks run into puddles. This final project discusses about the capacity of each cross-section of the river are experiencing water runoff when the high tide and also plans riverbank that safe against the tide.The method used is the field research in the form of geometrical data every 50 meters conducted along the river and tidal data in the upstream and downstream for 15 days through Admiralty. The field data were analyzed through a support program HEC-RAS 5.0 will get a cross-section tide experiencing water runoff and will get a safe levee elevation plans.The Results of the research showed that Anjir Mulawarman is 1.88 km, the river channel width is 16-39 meters, and the channel depth is 2.28 to 3.66 meters. The number of stations that were flooded due to tidal  as many as 14 of the total 39 stations, with the water level varied from 6 cm to 20 cm in the riverbank area including houses and streets. This cross-sectional capacity of 14 stations are not able to accommodate the tide, so it will planning levee or raising the banks to at least 7.5 meters above sea level elevation. Keyword : Anjir Mulawarman, Channel Cross Section, Tide, HEC-RAS 5.0

Abstract

Sediments can lead to continuous agradation and degradation that potentially alters river morphology. On the other hand, scouring occurs as a consequence of contraction due to the existence of a bridge. Contraction will make the flow form a hole under the pillar. Decreasing pillars due to scouring may endanger the overall structure of the bridge.The data used in the calculation of sediment volume is river discharge data, soil samples, and geometry of Negara River. The data were then fed into HEC-RAS 4.1.0, using four formulas: Laursen, Engelund-Hansen, Meyer Peter Muller, and Toffaleti, the calculations were then performed by HEC-RAS 4.1.0 and then analyzed. The analysis was done by using three months simulation time. While the technical data of Andi Tajang Bridge is modeled on HEC-RAS 4.1.0, and then calculates scouring by considering scouring due to contraction and pillar impact. The debit used in the calculation of the scouring of the bridge is the discharge design with 50, 100, 500, and 1000 Years reinstall.The result of research is the maximum average capacity of Negara River that is 374,214 ton/day, sediment discharge and sediment concentration are 35,347 ton/day and 6,668 mg / l. The biggest scour on Andi Tajang Bridge occurred at the discharge of 267,4116 m3 / d (re-time 1000 years) that is 2.98 m. Based on the results of the study, the sediment discharges occurring in the Negara River are of great value in some parts, so that sediment control is necessary. In addition, to prevent damage to the bridge structure due to scouring, it is necessary to make protection on the structure under the Andi Tajang Bridge. Keywords: sediment, scour, bridge, Negara River, Andi Tajang Bridge, HEC-RAS 4.1.0
