Abstract

The regions in foothills of Sago mountain are flood-prone area due to debris flow. As occurred on March 22, 2010, there has been a catastrophic overflow of debris flow from Sago mountain. The disaster resulted in severe damage around the rivers downstream Sago mountains, including Batang Lakin river. This research study debris flow potential and how to mitigate it in Batang Lakin river, West Sumatra. Analysis of potential debris flow hazard of Batang Lakin river and alternative debris mitigation is simulated using the debris flow simulator Kanako 2D version 2.051. Simulation is important for verifying effect of controlling  flow of debris prior to construction work carried out. Rain  data input was calculated based on fifty years time period and one hundred years time period  Research findings show that at Batang Lakin river, debris flow occurred and overflowing river channel. Alternative countermeasure chosen is sabo dam. For fifty years period when debris flow peak discharge of 59.50 m3/second required 2 units of sabo dams (closed type) with positions at Sta 0 +200 (Sabo height 6 m) and at Sta 0 +450 (Sabo height 4 m). For one hundred years period when debris flow peak discharge of 62.66 m3/second required 2 units of sabo dams (closed type) with positions at Sta 0 +200 (Sabo height 6 m) and at Sta 0 +450 (Sabo height 5 m) to prevent overflow of debris flow to the settlement. Thus, the right efforts to control debris flow on Batang Lakin is the sabo dam.  Keyword : debris flow, effective prevention, Sago mountain, sabo dam.

Abstract

Uwai weir which was built on 1938 is located on Bangkinang Seberang, Kampar District. As a result of river containment an inundation area called Embung was formed naturally with nonuniform topography. The distribution of flow velocity is not uniform and causing various flow pattern for every point on Embung Uwai.Flow pattern simulation which is used is qualitative and quantitative. Quantitative simulation based on velocity contour which was generated is divided into return period of 2, 5, and 10 years and by comparing the relation between velocity contour and water depth. Qualitative simulation was observed on water swirl and the flow that occured. The flow pattern generated fom simulation on return period of 2, 5 and 10 years didn’t show any significant different. Flow velocity distribution was compared based on return period of 2, 5, and 10 years. Results obtained was that the highest flow velocity is on section 3 with 0.07 m/s for return period of 2 years, 0.078 m/s for return period of 5 years and 0.08 m/s for return period of 10 years.Keywords : Weir, flow pattern, simulation

Abstract

Satria street is located at the flood plain of Sail River in Pekanbaru city which is oftenly flooded by high intensity rainfall during the rainy season. Due to its low elevation, water tends to flow and form puddles on the street area. This study aims to overcome the aforementioned problem by performing drainage normalization simulation at Satria Street using HEC-CRAS 4.1.0 software. The normalization was conducted by increasing both width and depth of the drainage ditch from the existing dimensions of 50 cm x 70 cm to 80 cm x 100 cm, and by changing the drainage slope at Satria Street. The design-flow rate an rainfall intensity was computed using rational method and mononobe method, respectively. The analysis result show that the flood problem can be coped by modifying the slope and dimensions of the drainage ditch.Keywords: flood, drainase, Hec-Cras

Abstract

The upstream watershed has a very important role in flowing water to the downstream area. Upstream watersheds located in highlands usually have very steep slopes with slopes of more than 15%. This causes the potential for erosion in the upstream to be large. The potential for erosion will be even greater because the steep slope causes a large amount of transport energy for water. Gravity will be greater with the slope of the slope. The purpose of this study is to classify and create a slope map of the Koto Panjang hydropower reservoir watershed. The method used in this research was data analysis with geographic information system software. The level of slope in the Kampar watershed varied greatly from flat (0-8%), gentle (8-15%), steep (15-25%), steep (25-45%), and very steep (>45%). Meanwhile, the Koto Panjang PLTA Reservoir watershed had a slightly steep slope (15-25%) covering an area of 104.465 km2, steep (25-45%) covering an area of 484.893 km2, and very steep (>45%) covering an area of 2747.813 km2. Based on the slope level in the Koto Panjang PLTA Reservoir watershed, the LS value in the watershed is 8.907.Keywords : watershed, erosion, slope

Abstract

The non-uniformity topography of Sei Paku Reservoir caused non-uniform flow in the reservoir, forming unique flow pattern. This flow pattern caused the uneven of flow velocity distribution and sediment distribution in the reservoir. The uneven of flow velocity distribution and sediment distribution can affect the trend of bed configuration changes of the reservoir. It takes a form of a simulation study to determine the pattern and flow velocity distribution, and sediment distribution in the reservoir. In the simulation, topography data, flood discharge, and the water level are processed by RMA-2 that produces flow patterns and the flow velocity. Parameters such as sediment grain size and sediment concentrations are processed by SED2D that produces sediment distribution. The simulation results showed that the flow patterns affect the flow velocity distribution and the sediment distribution in the reservoir so that happen bed configuration changes of the reservoir. The bed configuration of Sei Paku reservoir classified by simulation results in “Anti Dunes” phase where upstream side suffered deposition while downstream side suffered erosion.Keyword: Simulation, flow pattern, sedimentation
