摘要

本研究旨在探讨斯瓦特地区Daral和Chail山谷山区社区的山洪恢复能力及其评价。在收集一手资料和二手资料后,应用灾后恢复能力(DRC)模型参数进行数据分析。分析表明,夏季河流流量增加的主要原因是冰雪、冰川和季风性降雨的快速融化,导致山洪暴发。生活在Daral和Chail山谷山区的社区几乎每年都面临着大量社会经济和基础设施遭受山洪破坏的问题。然而,有限的社区已经采取了本土的恢复力战略,从反复发生的山洪的不利影响中恢复过来。分析发现,由于当地社区的土著复原力实践和大多数山地社区的位置,与Chail山谷相比,Daral山谷对山洪暴发的抵御能力更强。与此相反,Chail山谷的山洪恢复能力和水平较低,因为大多数山区社区更容易受到季节性山洪的影响。一些明智的做法可以增强对山洪暴发的抵御能力,特别是土地利用规划、社区准备、植树造林以及改善可达性和通信。

Extent and Evaluation of Flash Flood Resilience in Mountainous Communities of Daral and Chail Valleys, District Swat, Pakistan
This study aimed to explore the extent and evaluation of flash flood resilience in mountainous communities of Daral and Chail valleys of Swat. After collecting data from primary and secondary sources, the parameters of Disaster Resilience Capacity (DRC) model was applied for data analysis. The analysis reveals that stream discharge increases during summer mainly because of the rapid melting of snow, ice, glaciers and monsoonal rains, which results in flash floods. The communities living in the mountainous areas of Daral and Chail valleys face problems of multitudes of socio-economic and infrastructural flash flood damages almost every year. However, limited communities have adopted indigenous resilience strategies to bounce back from the recurrent adverse impacts of flash floods. It was found from the analysis that due to indigenous resilience practices by the local communities and the location of most mountainous communities, Daral valley is more resilient to flash floods as compared to Chail valley. Contrary to this, the extent and level of flash flood resilience in Chail valley are low as most of the mountainous communities are more vulnerable to seasonal flash floods. Some wise practices can enhance resilience to flash floods, especially land use planning, community preparedness, afforestation, and improved accessibility and communications.
