Abstract

The development of Sianok Canyon area as a tourist destination in Bukittinggi-Indonesia also needs a disaster risk reduction to be included in. The city already has land use plan that restricts the development around the upper part of the Canyon. This restriction is not equally effective because it has no consideration based on the actual thinking. The study that provides a scientific consideration is needed since the city has limited land. Then, the geological study and geotechnical investigation was done to obtain required data. It is followed by the potential landslide analyses of the Canyon area. Furthermore, based on the results of the analyses the safety factor and safe distance criteria are proposed for consideration in the development plan of the city as well as to reduce the disaster risk.

Abstract

There is a rapid development in Air Pacah area since 1999. This area used to be a remote area and a retarding basin of Padang City. In 2011, it was designated as the new head quarter complex for Padang City government. One of the negatife impacts of its development was the increase of flood frequency. In order to mitigate the flood, government conducted a flood control project at Maransi River which passes this area. However, this project has not completed yet due to land acquisition problem. Accordingly, this paper aims to identify community perception on flood causes and into what extent the flood control project has benifited the community. Thirty semi-structure interviews were conducted between May and October 2015 and analysed using descriptive statistic and content analysis method. It was found that community feels that there has been an increase in flood frequency, flood depth, and flood duration. There are four dominant factors that have significant impact on flood, rain duration, low infiltration area, massive construction of real estates and offices, and bad drainage system. Community who live exactly next to the construction site has benefited from the flood control project, on the other hand community at the upstream has not feel the positive impact yet because the construction halted due to land aquisation problem. As a result, it is strongly recommended that government to immediately acquire the land needed for the flood control project.
