Abstract

The Cikapundung River is one of the rivers that divides the city of Bandung and is often used as the main drainage center of the city, the flow of sewage or waste, tourism objects, and raw water sources. This causes the importance of observing reliable discharge values flowing on the Cikapundung River. In this study the authors analyzed the availability of minimum river discharge in Cikapundung Hulu Sub Das using the FJ Mock method. This study uses rainfall data and climatology data. The rainfall data used are rainfall data from Dago Pakar station and Meteo Lembang station, with a span of 10 years while the climatological data used is data from the Bandung Geophysical Station with a span of 10 years. Mainstay discharge calculated using the F.J Mock Method, where in the F.J Mock calculation there are a number of parameters assumed. This modeling test process is by calibrating the parameters assumed by Trial and Error. The average discharge magnitude for Q50, Q80, Q90, and Q95 in calculating the mock model in the period 2008 to 2014 resulted in a value of 3.87 m³ / sec; 2.98 m³ / sec; 2.46 m³ / sec; and 2.21 m³ /sec. While the discharge values of Q50, Q80, Q90, and Q95 in the observation debit produce successive values of 3.85 m³ / sec; 2.45 m³ / sec; 2.05 m³ / sec; and 1.91 m³ / sec. Even with the increase in the calculation period, reliable debit values have a tendency to rise.

Abstract

Floods in the Cikeruh watershed often occur every year during the rainy season. In addition to the rainy season there are several other factors that influence, such as slope, land height, soil type and land use. With this study, it is expected to be able to provide information on the location of floods in the Cisadane watershed with the aim of helping to make decisions in carrying out actions, prevention, reducing the risk of flooding. The data used in this study are secondary data, namely the average annual rainfall data from 13 stations, soil type data, DEMNAS data (National Elevation Data Model), RBI maps with a scale of 1: 25,000 and Cisadane watershed maps. The method used in this study uses the scoring and overlay method where each parameter used to analyze the level of flood vulnerability in the Cisadane watershed is rainfall, slope, elevation, soil type, distance to the river (river buffer), and use land that is given a value and weight according to the classification of the level of vulnerability. Processing data in this study using ArcGis 10.2.2 software. The results of the study resulted in a map of flood vulnerability levels in the Cisadane watershed which provided information on the distribution of locations prone to flooding. Around 76.77% or 116,178,559 ha of the Cisadane watershed area is prone to flooding with a very high vulnerability to the level of medium vulnerability that is spread from upstream to downstream
