摘要

摘要2012年8月1日，印尼马鲁古群岛的纳西里小村庄连续遭遇两次山洪暴发。洪水摧毁了61所房屋，其中一些被冲入海中。两年后开发了一个监测和社区预警系统。本文介绍了该系统的方法、开发和实现。有两个组成部分，即社区能力建设和建立遥测监测。洪水预警系统考虑了两个原因：极端降雨和滑坡溃坝。提高认识、举办讲习班、培训和建立灾害组织似乎有效地提高了洪水灾害防备能力和社区承诺。采用降雨深度与强度图的方法发布洪水警报似乎很有希望。在极端降雨期间，记录中出现了异常的流量减少，这表明由于山体滑坡，记录站上游出现了筑坝现象。下游至中游附近可能存在的滑坡坝可能会在短预警时间内引发危险的洪峰流量山洪。

Flood monitoring and community based flash flood warning system for Nasiri River, West Seram, Maluku

ABSTRACT On 1st of August 2012, two successive flash floods hit Nasiri hamlet in Maluku archipelago, Indonesia. The floods destroyed 61 houses and swept some of them down into the sea. A monitoring and community-based early warning system (MCBEWS) was developed 2 years later. This paper presents the approach, development, and implementation of the system. There are two components, namely community capacity-building and the establishment of telemetric monitoring. The flood warning system considers two causes: extreme rainfall and landslide dam breaks. Raising awareness, workshops, training, and disaster organisation establishment appeared to effectively increase flood disaster preparedness capacity and community commitment. The adoption of a rainfall depth vs. intensity chart method for issuing flood warnings seems to be promising. The presence of an unusual flow reduction in the record during extreme rainfall indicates damming at the upstream of the record station due to landslides. Possible landslide dams near the downstream to the middle reaches might provide dangerous high peak discharge flash floods with short warning times.

期刊介绍： The Australasian Journal of Water Resources ( AJWR) is a multi-disciplinary regional journal dedicated to scholarship, professional practice and discussion on water resources planning, management and policy. Its primary geographic focus is on Australia, New Zealand and the Pacific Islands. Papers from outside this region will also be welcomed if they contribute to an understanding of water resources issues in the region. Such contributions could be due to innovations applicable to the Australasian water community, or where clear linkages between studies in other parts of the world are linked to important issues or water planning, management, development and policy challenges in Australasia. These could include papers on global issues where Australasian impacts are clearly identified.
