Abstract

Stages of disaster mitigation study consists of the level of hazard, vulnerability and capacity. Pekanbaru, the capital of Riau province has the potential to flood inundation. An assessment of the vulnerability of flood inundation using GIS technology be done in twelve districts in the city of Pekanbaru. This study was conducted as a early warning to the public and to the relevant parties. This study uses two parameters causes of flood inundation, such as the parameter of flooding inundation (landform, slope either side of the river, damming the river branching, meandering rivers, and waterworks) and parameters of flood inundation potential water supply (rainfall, river basin shape, drainage density, slope watersheds, and land use). By analyzing satellite imagery data (DEM and Landsat 8 OLI), rainfall data, and administrative map of Pekanbaru City area with the help of GIS technology, the results of the analysis of these two parameters indicate that the city of Pekanbaru has a weighted average score is 2.70, so that the city of Pekanbaru has a severe impact categories rather prone to flooding inundation. The weighted scores of the two parameters in the city of Pekanbaru has shown that the land (weighted score of 1.33), the availability of water building (weighted score of 2.25), and the use of land (weighted score of 1.20) has a considerable influence on the cause of the flood puddles in the city of PekanbaruKeywords: inundation flood, GIS, parameters of flood, vulnerability

Abstract

The increase of population growth has caused damaged to Kampar River becoming and also exploitation for human needs. The exploitation came in the for of riverbed material such as sand and gravel for construction needs. The effect of material mining is the erosions that caused the river to be deeper and also the erosions at the cliff that caused the river to be wider thus causing the disposition of river meander. Remote sensing data is needed to identify the magnitude of erosions and sedimentations on Kampar River so that the change in morphology of Kampar River can be identified. Morphology changes on Kampar River can be identified by means of overlaying the digitized map the previous satellite data with the next satellite data. Thus, the research regarding riverbed material mining of Kampar River to identify the changes of morphology on Kampar River using remote sensing technology.This research used satellite data of Landsat-5 TM, Landsat-7 ETM+ and Landsat-8 OLI TRS which were acquired from United States Geological Survey (USGS). Satellite data which were used are 1994, 2000, 2007, 2010 and 2014 data. The result of the research showed that the erosions on 1994 until 2014 was 1.152.115,56 square meters or 115.211 hectares. Meanwhile the sedimentations on 1994 until 2014 was 1.241.084,95 square meters or 124.108 hectares.Keyword : Morphology, remote sensing, landsat, erosions, sedimentations

Abstract

Change of land use in the Kaiti watershed will influence to surface flow. This surface flow will increase the potential for land erosion and sediment transport capacity. This will have a major impact on the functional life of the Cipogas Lake reservoir. The USLE method is used to estimate erosion that occurs in watersheds with the help of GIS. GIS is used to predict the size of USLE parameters. The results of the analysis show that erosion occuring in the Kaiti river basin classified as heavy class (>480 Tons/Ha/Year) and the erosion potential that will enter the Kaiti reservoir is 216,273.387 tons/yr.

Abstract

Sei paku irrigation area is located in Kampar Kiri District, Kampar Regency, Riau Province, this irrigation area is specifically planned for rice fields with total area of ± 1000 Hectares. Function change from agricultural land into fish ponds and palm plantation resulted potential land decrease to ± 350 Hectares. Uncontrolled water utilization for fish pond, channels leakage and influence of meteorological factors resulted water supply shortage for agricultural land and water deficit for certain month.Analysis of evapotranspiration, effective precipitation, percolation and water replacement are used to determine the value of the rice water requirement of plant and crops planting. Fish pond water demand and oil palm plantations is used as a reduction of the value of intake discharge, which then the rest of discharge will be used as a main rate of flow for fulfilling plants water needs. In March, May and July crop water requirement is greater than the mainstay discharge, then a simulation done by allocation of planting schedule that is 5 group for rice planting and 3 group for crops planting.The results showed that planting schedule can reduce the value of the maximum water deficit in the existing condition that is 0.36 m3 / s to 0.041 m3 / s or decreased 88.61%, but the deficit is still occurs. So it is necessary to do a Long Storage planning with 2000m long, width 5m and 5m depth with a land area of 1.2 hectares which function as water reservoir that can be used to fulfilling the crops water needs on dry meteorological conditions.Keywords: Sei Paku Irrigation Area, water deficit, water balance, critical discharge, weirs, and long storage

Abstract

Irrigations networks in irrigations areas of Sei Paku have a very low efficiency value due to the exploitations of fish ponds and recreations ponds. Exploitations activities on the upstream is watering fish ponds and recreatiol ponds that’s effect is water loss, so make deffeclency water at downstream areas. Result water loss on the flow influence at primary flow. Efficiency analysis flow use to know efficiency primary flow. Topographic data, speed flow, and dimensions of channel are needed to analyze the value of primary flow efficiency existing in the field. Efficiency analysis is done by directly measurement in the area as much as 5 periods. Based on the analysis results that the biggest water loss at T45 – T61 segmen as much Qt = 0.0960021 m3/second and smallest water loss at T91- T101 segmen as much Qt = 0.0000007 m3/second. The efficiency of the existing pyrene channel in the field is 9.41%.Keywords : Irrigations Areas Sei Paku, waterloss, and efficienc.

Abstract

Pillar of the bridge on the stream causes changes flow patterns and local scour. Local scour will decrease the power of pillar to sustaining bridge load. Laboratory model was conducted to determine the model of local scour phenomena double circular pillar with or without protector curtain type. Basic canal model is using kampar sand with grain size d35 = 0,285 mm, d50 = 0,330 mm and d65 = 0,380 mm and spesific weight is 2,64.Froude number that used is Fr1=0,464, Fr2=0,670 and Fr3=0,769. Reynold number Fr1 scored 1658,42 is classified as transitional flow, Fr2 scored 3081,68 and Fr3 scored 4381,19 is classified as turbulent flow. Shield shows the use of gradation in moving zone. Hydrodynamic flow in pillar causes down flow that showed by scour in upstream pillar. Scour rech the equilibrium stage at minute 75. The ratio of scour depth ds/b is range from 0,03 – 0,46. The use of swivel can reduce the scours depth until 44,44%. Sediment transport analysis prove that the higher Froude is used the bigger the granules  are transported.  Key word  : scour, model laboratory, double circular, froude, reynold, Shields, hydrodynamic flow, sediment transport .
