Streambank fish-shelter structures help stabilize tributary streams in Wisconsin

 A significant proportion of stream sediment yield in North America comes from stream channel and bank erosion. One method used for stream stabilization is the bank installation of timber and stone fish-shelter structures, but there is little evidence for their potential effectiveness. Nine to nineteen years of precise survey data from Coon Creek, Wisconsin, however, show that fish structures enhance sediment deposition along the stream and may retard lateral migration of channels. Such structures have greater utility for sediment control when streams are eroding away a high bank and replacing it with a lower bank. Received: 18 October 1996 · Accepted: 4 February 1997     

城市应急管理模型之设计

随着城市建设的快速发展 ,各类危及国家和人民群众生命财产安全的突发性事故灾害时有发生 ,尽管各有关部门的抢救队伍在实施抢险救援中发挥了积极作用 ,但各抢险救援力量专业单一、分散行动 ,形成不了合力 ,难以及时有效处置重大或特大突发性、综合性、大面积的城市事故灾害 ,特别是像地震以及的美国的 9 1 1那样突发性事故。我们目前开展的震害预测与灾害快速评估系统只是针对地震的 ,而地震是小概率事件。因此要应对城市各种重大突发事件 ,城市有必要建立一种应急机制或综合的应急管理信息系统。根据“数字城市”的思想 ,通过一个通信系统与信息系统集成的平台 ,统一协调公安、消防、急救、交警、公共事业、民防、地震等政府部门 ,为市民提供快速、及时的各种救助和相应的服务。统一报警、统一指挥、快速反应、联合行动 ,从而有效地减少损失。     

第二松花江干流区地下水信息管理数据库系统开发与研制

介绍了第二松花江干流区地下水信息管理数据库系统的开发环境及总体设计。在分析与地下水有关的数据信息的基础上,提出了较为合理的地下水信息管理数据库系统的结构。将该系统按其功能分为5个子系统基础子系统、数据信息管理子系统、区域信息管理子系统、动态绘图子系统、水资源评价子系统,并对5个子系统的功能进行了详细阐述。     

Earthquake Disaster Management and Insurance

As one of the most powerful tools to reduce the earthquake loss, the Earthquake Disaster Management [EDM] and Insurance [EI] have been highlighted and have had a great progress in many countries in recent years. Earthquake disaster management includes a series of contents, such as earthquake hazard and risk analysis, vulnerability analysis of building and infrastructure, earthquake aware training, and building the emergency response system. EI, which has been included in EDM after this practice has been done for many years, include these contents: insurance model, financing. This paper presents the development of china in EDM and EI. The main contents include: (1) the statue and trend of earthquake disaster management and insurance in china; (2) the progresses and new methods about the seismic risk zonation and vulnerability analysis, and the future developing trend, the application of GIS in earthquake disaster assessment is introduced; (3) the way and illustration in building the earthquake disaster e

Development of an integrated conceptual model for the rational management of the transboundary Nestos River, Greece

This paper provides a detailed analysis of the geologic, hydrologic and hydrogeologic characteristics of Nestos River basin, which is formed within the Greek mountainous part of the river. The quantitative analysis was mainly based on the data of the river flow in different gauging points across the rivercourse as well as on the data of groundwater discharge from karst springs of the mountainous area while important conclusions were made regarding the hydraulic connection between the surface waters of the river and the groundwater of the karst aquifers of the basin. The qualitative analysis has shown that the quality of both surface waters and groundwaters of the investigated basin is high, whereas, no sources of contamination were indicated during this research. The possible effects of the two large dams of Platanovrisi and Thesavros are also analysed as they strongly affect the quantitative and qualitative regime of the river delta.
