Reservoirs in the wet tropics generally have a fairly rapid sedimentation problems. Not infrequently happens that has begun to operate reservoirs showed symptoms of increased sedimentation. This paper aims to find and solve problems that arise due to the high rate of sedimentation and deposition in the Koto Panjang reservoir hydropower, Riau province in an effort to preserve the continuity of electric energy in Riau Province. Method approach taken to describe the pattern of relationship between flow rate, sedimentation and the characteristics of the reservoir as a basis for watershed management in the upstream using regression equations developed by Singh and Chen (1982). The results of the investigation show that the land area (Af) in the upstream has a dominant influence on the rate of annual sediment entering the Koto Panjang reservoir hydropower. For the reduction of land area by 15%, an increase in the volume of sediment from 1.4 million m3 to 11.4 million m3.

The aim of this research was analyze cost estimation budgeting for river normalization of length 6 kms atau 6000 m from River Mouth of Mendol, Kuala Kampar Residence, Pelalawan District, Riau Province. Method was used used to analyze bad level design of Mendol River using Linearly Method Software’s Excel 7.0. The result of this research prove that bad level design of Mendol River from upstream to downstream (river mouth) is 0.07% and cost estimation budgeting is Rp.614.841.965.

PREDIKSI KETERSEDIAAN AIR SEBUAH DAERAH ALIRAN SUNGAI MENGGUNAKAN PENDEKATAN MODEL RAINRUN Imam Suprayogi; Manyuk Fauzi; Bochari -; Resty Agesti Handayani

Dependable flow analysis is often difficult to predict, because influenced by natural phenomena and there are have variability of space and time. In analysis dependable flow especially the Sumatera region, usual model is used is Mock Model . However the level of reliability and accuracy have not been fully answered than the prediction of dependable flow. So it needs to be tested using a model that other rainfall-run off.The model approach used in this study is RainRun, that to predict dependable flow for applied on Sumatera region. Data is used to apply of RainRun model is Indragiri Basin for the years 1995 to 1999 are rainfall, climatological and measured discharge.The result study showed that the RainRun model to Indragiri Basin in calibration phase Root Mean Square Error (RMSE) value respectively 1,327% and verification obtained RMSE value respectively 2,811 %. Where as Mock watershed model for same Basin in calibration phase RMSE value 5,298% and the verification phase is obtained RMSE value 13,760 %. The results of comparative models RainRun and models Mock by using statistical parameter RMSE test RainRun models showed a lower error rate than the model of Mock.

The main purpose of this research is doing a review of inpipe energy loss using a laboratory-scalephysical model approach to establish the graphic of relation pattern between friction factor (f) toReynoldsNumbers (Re) and also the graphic of relation pattern between pressure height (h) to the stream’svelocity (v).This research used a laboratory-scale physical model approach. The instrument used wasPipeFrictionApparatus which equipped withHydraulicBenchmade by ArmfieldInc., USA in 2006.The main resultproved that the amount of in-pipe energy loss (hf) was highly influenced by the friction coefficientparameter (f), pipe diameter (D), pipe length (L) and also the velocity of in-pipe stream (v). The secondaryresult showed the type of stream in this laboratory-scale research was a turbulence one.
