碩士 === 國立東華大學 === 自然資源與環境學系 === 107 === Soil and Water Conservation Bureau, in the past few decades, have been training enthusiastic local leaders and elites to become debris flow disaster prevention volunteers with the hope of forming self-mobilized disaster prevention communities so that there can be local-based experts who may provide on-time alerts, report live information to proper authorities and thus may have impacts of disasters may be kept to the minimum or even be prevented. Debris flow disaster prevention experts have long been seen contributing a lot to disaster prevention education, evacuation thrills and best of all, disaster report. And their collection of rainfall as well as other hydrological information may come in as plus on top of meteorologists’ studies weather, appearing especially helpful during typhoon and torrent seasons; these experts have their crucial role in keeping our people safe. The current research is to compare and contrast the rainfall collected by these experts and reports at meteorological stations and the application of these volunteers’ data on disaster prevention. Results show that data collected by those volunteers and meteorological reports may be “completely congruent, completely incongruent and partially discrepant” and that may be attributed to (1) geological formation of the spot the volunteer reported from (2) distance between the spot the volunteer was at and the meteorological station (3) route of the typhoon. With Thiessen Polygons Method to categorize sections that a meteorological station may cover, the researcher discovers that an area that has a meteorological station, potential debris flow torrents, protected objects but no experts may need to be scrutinized as well. Contributions of a debris flow disaster prevention expert may include (1) to include information that rainfall report might miss out (2) to urge preventive evacuation (3) to boost necessary establishment of additional meteorological stations.
