Overview on Mangrove Forest Disaster Prevention and Mitigation Functions

This paper provides a comprehensive overview on coastal protection and hazard mitigation by mangroves.Previous stud-ies have made great strides to understand the mechanisms and influencing factors of mangroves’protection function,including wave energy dissipation,storm surge damping,tsunami mitigation,adjustment to sea level rise and wind speed reduction,which are sys-tematically summarized in this study.Moreover,the study analyzes the extensive physical models,based on indoor flume experi-ments and numerical models,that consider the interaction between mangroves and hydrodynamics,to help our understanding of mangrove-hydrodynamic interactions.Additionally,quantitative approaches for valuing coastal protection services provided by man-groves,including index-based and process-resolving approaches,are introduced in detail.Finally,we point out the limitations of previous studies,indicating that efforts are still required for obtaining more long-term field observations during extreme weather events,to create more real mangrove models for physical experiments,and to develop numerical models that consider the flexible properties of mangroves to better predict wave propagation in mangroves having complex morphology and structures.

RESEARCH ON SYSTEM OF FLOOD DISASTER CONTROL AND REDUCTION SUPPORTED BY GIS IN MEDIUM AND SMALL BASINS

Southeast China coastal areas belong to subtropical monsoon climatic zone, thus easily affected by floods resulted from typhoons and rainstorms. Since the areas of river basins are small, rivers flood regulation capacities are low, and therefore flood hazard is grave. In this paper, taking the Yongjiang basin in southeast China as an example, the approaches and methods of geographic information system(GIS) applied to flood disaster control and reduction research on small basin are explored. On GIS help the rainfall runoff calculation model and the river channel flood routing model are developed. And the evaluating flood submerged area and the damage assessment models are built supported by digit elevation models. Lastly the decision support system on GIS supported for flood control in research basin has been set up. This greatly improves flood proofing decision making capacities in river basin, and provides valuable information and a mode for flood prevention and reduction in the medium and small basin. Meanwhile, the research indicates that technologies of GIS provide a powerful tool for flood disaster control.

The Stava Valley Tailings Dams Disaster:A Reference Point for the Prevention of Severe Mine Incidents

On July 19,1985,at Stava near Tesero(Italian Alps),two reservoirs collapsed,causing the death of 268 people and the destruction of many buildings.The two adjacent basins were constructed for the decantation and storage of fine-grained waste material,which was pumped from a nearby fluorite mine.The consequence of the failure was a vast flowslide that found its way downstream along the Stava valley destroying many houses in the village of Stava,eventually reaching Tesero,where more property was wrecked or severely damaged.The Stava valley disaster was one of the most tragic of its kind.This paper aims to give a contribution on the technical aspects related to the causes of this catastrophic event.It also describes alternative technical solutions for the proper management of mining waste disposal and environmental protection proposed by the Stava 1985 Foundation for disseminating knowledge and awareness on how to make these geotechnical structures safer and more profitable and avoid other similar disasters that still keep occurring every year around the world.

四川泸定M_(s)6.8地震房屋震害及人员死亡特征分析

在收集整理四川泸定M_(s)6.8地震现场调查资料的基础上,对比九寨沟M_(s)7.0地震,分析房屋震害特征和人员伤亡情况。结果表明,相较九寨沟地震,四川泸定M_(s)6.8地震灾区房屋震害更为严重,遇难人数更多,主要原因是房屋抗震能力不足、选址不合理以及地质灾害较为发育等。灾区房屋结构类型主要有钢混结构、砖混结构、穿斗木结构、石木结构、砖木结构、土木结构等6类。对房屋平均震害指数和易损性曲线的分析表明,未设防的砖混结构、简易结构房屋抗震能力弱,震害比其他结构房屋严重;而人员死亡主要由地震地质灾害造成,集中在高烈度区和地质灾害易发区,死亡人员以中老年为主,人员死亡率与地震烈度、人口密度有明显相关性。灾区房屋破坏及人员伤亡具有高山峡谷地区的震害特征。本文的研究结果可为进一步研究该类地区的地震灾害风险研究提供参考。

Preparing Youth for Disasters: The Need for a Contextualised Disaster Risk Reduction Curriculum in Schools

This study draws from detailed qualitative case studies of three schools that practise disaster risk reduction (DRR) education initiatives in their curriculum in Nepal. Using curriculum mapping and discourse analysis, it aims to elaborate the significance of relevant disaster risk reduction (DRR) content in school curriculum to prepare youths for disaster response and recovery. It elaborates the nature of the current DRR content covered in curricula and textbooks and provides suggestions to address the identified disaster-related issues in the school curriculum. It further elaborates that incorporation of local and contextualised DRR content in school curricula contributes to the establishment of the “culture of resilience” in disaster prone context like Nepal. It concludes that more organised and holistic approach is essential to develop disaster and management knowledge, skills and attitudes to youths.
