Abstract

Teluk Belitung is located in Padang island, subdistrict Merbau, Kepulauan Meranti district with area of 1348.91 km2. Teluk Belitung coast is located in Asam the Strait directly related to the Melaka Straits and the South China Sea led to the current in the Strait acids affected by wind season (Monsoon). It causes waves in the Strait of relatively large during the rainy season. Because of ocean waves directly on the coastline, Teluk Belitung coast and the surrounding Islands are a relatively easy type of peat decomposes and reduced crop coastal protection (mangroves) as a binder, causing a serious erosion problems along the coast of Teluk Belitung. That requires an analysis of the rate of coastal erosion on the Teluk Belitung which is very important in order to mitigate natural resources and maintain the viability of the local community. This study uses historical data of high-resolution aerial images based Remote Sensing technology integrated with GIS (Geographic Information System). The data used aerial photographs for 24 Year ie 1989, 1996, 1999, 2001, 2004, 2009, and the result showed that 2013. accretion occurred along the 158, 311 m or 6.60 m / year and abrasion occurred along 292.397 m or 12.80 m / year. While the extent of the accretion occurs at 84.333 ha or 3.514 ha / year and the extent of abrasion that occurs at 151.972 ha or 6.332 ha / year.   Keywords: shoreline change, abrasion, accretion, remote sensing, Landsat.

Abstract

Synthetic Unit Hydrograph (SUH) is the most practical and simplest method in analyzing the flow rate in an ungauged watershed. It only needs the watershed characteristic data such as the area size of watershed and the length of the river. The flow rate data used in many water resource related planning activity such as drainage, water reservoir etc.. Some of the oftenly used SUH methodes are SCS (Soil Conservation Service), Nakaysu, Snyder’s, GAMA-I etc. The concept of Unit Hydrograph with the volume control/ DRO (Direct Run Off) value closest to1mm, is used to determine a proper SUH method to be applied on watershed. In the case study of Tapung Kiri watershed, the proper SUH method to be applied is the Nakayasu’s with the α = 2, and DRO = 0,992. Nakayasu’s is also the proper SUH to be applied in the Tapung Kanan watershed, with the α = 2, and DRO = 0,992.Keyword : UH, SUH, SCS (Soil Conservation Service), Nakayasu, Snyder, DRO, Tapung River

Abstract

The demand of raw water in Kampar Districts is increasing in step with population growth. At this time, the water supply system is regulated by PDAM Tirta Kampar what still have problem to service coverage. Especially Tapung Sub-District has not been served. Therefore, the existence of the Tapung Kiri River is expected to be a solution to overcome these problems. Thisstudy use IHACRES for rainfall - runoff modeling, which in the calibration stage reach Nash- Sutcliffe effectiveness value of 0.630. Overall, this model provides an understanding that thesuccess obtained on the calibration stage does not guarantee success in the verification stage. Analysis of water availability is done to analyze the realable discharge river (Q90%) based onaverage annual the discharge resulting realable discharge occurred in 2000. The greatest realable discharge occured in October amounted to 93.75 m3/sec, and the smallest in Maretamounted to 43,69 m3/sec. Analysis of water demand is forecasted to the population growth of up to 22 years and produce raw water demand total with forecasts early of the year (2013) of 0.109 m3/sec and the end forecasts of the year (2035) of 0.264 m3/sec.Keyword : Tapung Kiri River, IHACRES model, Availability Water, Population Forecasts, Water Supply

Abstract

One of parameters to determine the discharge is to know the pattern of rainfall distribution. To calculated the rainfall distribution is required hourly rainfall data of TRMM. Rainfall distribution patterns can be calculated using the empirical method of Alternating Block Method (ABM), Tadashi Tanimoto and Mononobe. The aim of this research to determine the pattern of rainfall distribution in the city of Pekanbaru from 2009 to 2016 based on the pattern and correlation. Based on shape, the most common TRMM distribution pattern is the bell shape that occurs from the duration of 3 to 9 hours and for the duration 2 hours has the form of a declining ladder. While based on correlation, pattern of rainfall distribution for duration of 3, 4, 6, and 7 hours tend to ABM Method, 5 hour duration tends to Mononobe Method and 8 hour duration tends to Tadashi Tanimoto Method. The results of this study have been compared with previous studies for Pekanbaru City, which of the two studies only rain with duration of 3 and 5 hours that have a match pattern.Keywords : The Pattern of rainfall distribution, Satellite rainfall data, Alternating Block Method (ABM), Modified Mononobe, Tadashi Tanimoto
