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

Tsunamis are ocean waves that can be caused by earthquakes, landslides or volcanic eruptions that occur at sea either vertically or horizontally. Population of Padang city, which is more than half the population living in areas relatively close to the beach. A large of population living and indulge in the coastal of Padang city caused an increasing vulnerability of the population to the dangers of tsunami. Effective evacuation planning is an effort to minimize the possible impact of the tsunami will occur. The research methodology consists of three phases: data collection, data analysis stage of the process network analisys in ArcGIS software and the third is the analysis phase. Service area is generated using a network analyst tool. Service area in this research means that the minimum area that can be reach by evacuee before tsunami come. The results show that the shelters are not able to cover all of the areas in tsunamiprone zones. The results show that the shelters allocated by KOGAMI and DKP can not cover about 9.5% and 10.9% evacuee in tsunami prone area respectively. To overcome this, the addition of potential new shelter building must be allocated in non covered service area.  Keywords: tsunami, evacuation, shelter, network analyst, service area
