Abstract

The risk of damage due to flooding can be prevented by mapping the area or scope of flood inundation. Flood characteristics in the form of inundation area, inundation depth and flow velocity need to be mapped so that they can become the basis for flood control planning. This research aims to analyze the level of flood vulnerability in Fahiluka village based on the characteristics of the floods that occur. Hydrological analysis shows a trend of increasing rainfall over the last 12 years due to the impact of global climate change. The results of flood simulations for return periods of 25, 50 and 100 years using Hec-Ras 2D version 5.0.7 software show that the area of the village that has the potential to be inundated is 500 ha, 750.29 ha; 1020 ha with flood depths varying between 0.5 m 4.25 m with medium-high hazard categories.

Abstract

There have been several major natural disasters that have attacked Kupang City in the last five years, namely the Seroja tropical cyclone disaster, a 5.1 Magnitude earthquake, and a moving mountain disaster. With several disasters that occur quite often in NTT Province, especially Kupang City, it is undeniable that this has been predicted and warned by BMKG to the Community. This proves that the Community can be said to be unprepared to face and mitigate natural disasters that will occur. Therefore, based on this background, a Community Service activity was held in the form of Natural Disaster Mitigation Training and Simulation in one of the locations in Kupang City, namely the Nunsui, Oesapa Village. The training materials that will be provided are in the form of natural disaster mitigation (before, during, and after it occurs) from three examples of civil engineering fields, namely construction, transportation, and cost management. It is hoped that with the training and simulation activities, the community can understand how dangerous the disaster that might hit the inhabited area is, and the community can respond better to the intended disaster mitigation methods
