Strategic regeneration: A policy coupling approach to managing a coastal resort in South Wales

This review paper takes a case study approach to critically discuss how regeneration in the coastal resort of Porthcawl, South Wales has integrated flood defences as part of a strategic spatial planning and integrated policy coupling approach to the redesign of the town's seaside, promenade and harbour quarter. This planned initiative is part of a concerted effort to upgrade the town's waterfront and enable regeneration of a small seaside resort. From a resort cycle perspective, Porthcawl's perceived vulnerability to changing economic fortunes has prompted a master planning approach which is intended to bring together a mixed-use development programme with particular attention to urban design, strategic environmental assessment and public consultation. In different ways, this process has sought to raise public awareness of the issues and risks associated with the town's coastal location and to integrate flood defence aspects within the strategic regeneration plan as part of a greater sensitivity to climatic risks and potential flooding. This paper examines the adaptive capacity of coastal communities and the complex of socio-economic and spatio-temporal perspectives that shape policy developments in the planning, development and proactive management of coastal environments. The paper identifies the need to accommodate a new civic awareness of potential environmental hazards in articulating the public interest and balancing the trade-offs involved.     

动态主逻辑图--一种改进的安全风险建模方法

用主逻辑图,可以比较直观地建立起复杂系统的安全风险模型,但是这种模型运用的是布尔代数理论,所以无法模拟具有动态行为的系统.动态主逻辑图就是在主逻辑图的基础上,运用模糊数学（逻辑）的理论,分析复杂系统中的动态行为.介绍了动态主逻辑图的8种基本形态,并以利用动态主逻辑图对系统进行全面诊断和描述系统的部分失效的行为为例,简要说明了动态主逻辑图的新特点.     

URBAN WATER MANAGEMENT AND COASTAL WETLAND PROTECTION IN COLLIER COUNTY,FLORIDA1

ABSTRACT: Traditional development in South Florida has in many cases resulted in undesirable degradation of terrestrial and aquatic ecosystems, due to overdrainage and overenrichment of surface waters. The study described in this paper was undertaken in order to establish guidelines under which urban development may take place in coastal areas, while minimizing unwanted environmental changes. The study area consists of approximately 70 square miles of relatively flat land in Collier County, Florida. The coastal wetlands of the region are a highly valued natural resource containing the Rookery Bay Wildlife Sanctuary. The upland properties are mainly pine woodlands and have great potential for development. A master plan was developed which will (1) provide adequate drainage for existing and projected development within the study area and (2) maintain the integrity of the estuarine zone. The major recommendations of the plan relate to land use, physical control of surface waters, including construction and maintenance of the water management system, and implementation of the plan.     

PREDICTION OF MASTER RECESSION CURVES AND BASEFLOW RECESSIONS IN THE LUQUILLO MOUNTAINS OF PUERTO RICO1

ABSTRACT: An analysis of hydrograph recessions and rainfall data was performed to estimate the recession constants for two watersheds in the Luquillo mountains of Puerto Rico. To account for seasonal rainfall patterns, the data were grouped into dry and wet seasons. Sets of three Master Recession Curves (MRC) per season for each watershed were developed: one using the Matching Strip Method (MS) and two using variations of the Correlation Method (CM). These variations were the envelope line (CME) and the least squares regression (CMR). Other regression based analytical expressions that consider the streamflow recession as an autore‐gressive or an integrated moving average process were also applied. The regression based methods performed consistently better than the graphical ones and they proved to be faster, easier, and less subjective. The recession constants from these methods were then used to estimate the time it would take the streamflow to reach the critical Q₉₉ flow duration. Based on this study, once the streamflow reaches Q₉₀, water managers have 6 to 12 days warning before streamflow reaches critical levels.

THE DEVELOPMENT AND IMPLEMENTATION OF A GIS-BASED CONTAMINANT SOURCE INVENTORY OVER THE SPOKANE AQUIFER,SPOKANE COUNTY WASHINGTON1

ABSTRACT: U.S. Environmental Protection Agency (EPA) statutes require identification of all potential sources of contamination within a wellhead protection area. All wells over Spokane County's aquifer are included in one wellhead protection zone called the Aquifer Sensitive Area (ASA). A GIS-based Contaminant Source Inventory (CSI) was developed for the ASA. Datasets listing businesses and agencies within the ASA were imported into the GIS from state, county, city, and local agencies. These datasets were selected, joined, and sorted using GIS relational database capabilities into one ASA “business master file.” Map files were projected and transformed into common coordinates. Next, business sites within the master file were spatially related by address to the digital map files. Likely Critical Materials Users (CMU) were identified by sorting on selected standard Industrial Codes (SIC). Additional files of CMUs were imported into the Contaminant Source Inventory. GIS queries were performed to locate specific materials, quantities, and storage facilities, and to analyze CMU activity within selected buffer zones. This project demonstrated the usefulness of GIS technology in the development, management, maintenance, and analysis of vast quantities of data associated with a local wellhead protection pro. gram.     

工程系统一体化安全风险模型研究

借鉴功能模拟原理,利用目标树-成功树-主逻辑图(GTST-MLD)框架,提出了一个一体化安全风险模型。该模型对关联于工程系统安全特性的目标、功能、结构、行为等因素予以综合,提供了从多层次研究解决安全问题的模型基础,克服了基于事件树/故障树模型的概率风险评估等传统方法而分别对系统结构、行为、事件进行研究的问题,支持实现在更高的系统功能层面上对系统安全性的分析研究。通过研究该模型在安全风险评估、事故因果关联分析、潜在交互作用鉴别中的应用,表明研究成果为解决复杂工程系统安全问题提供了新的分析手段。
