Hydraulic Jet Control for River Junction Design of Yuen Long Bypass Floodway, Hong Kong

The Yuen Long Bypass Floodway (YLBF) was designed to collect flows from the Sham Chung River (SCR) and the San Hui Nullah (SHN) and to serve as a diversion channel of the Yuen Long Main Nullah (YLMN). Under a 200-year return period design condition, the floodway was designed (1) to divert a flow of approximately 38?m3/s from the supercritical YLMN flow and (2) to convey a total combined flow of 278?m3/s to downstream within acceptable flood levels. The success of the design depends critically on complicated junction flow interactions that cannot be resolved by 1D unsteady flow models. These features include the supercritical-subcritical flow transition at the San Hui-Floodway (SHN-YLBF) junction and the diversion of part of the supercritical flow from the Main Nullah (YLMN). A laboratory Froude scale physical model was constructed to study water stages and flow characteristics in the floodway and to investigate optimal design arrangements at channel junctions and transitions. This paper summarizes the main features of the unique river junction network, in particular the use of the hydraulic jet principle at the SHN-YLBF junction to lower flood levels. In addition, a numerical flow model is employed to study flow details at the river junctions. The model is based on the general 2D shallow water equations in strong conservation form. The equations are discretized using the total variation diminishing finite-volume method which captures the discontinuity in hydraulic jumps. The numerical model predictions are well supported by the laboratory data, and the theoretical and experimental results offer useful insights for the design of urban flood control schemes under tight space constraints.     

Proposed Fire Safety Ranking System EB-FSRS for Existing High-Rise Nonresidential Buildings in Hong Kong

A Fire Safety Ranking System (EB-FSRS) is proposed for assessing the fire safety provisions in existing high-rise nonresidential buildings in Hong Kong. The objective is to investigate how far the fire safety provisions in those existing buildings deviate from the expectation of new codes. Suitable fire safety management can then be worked out in the transition period, based on the scores. Local fire codes were reviewed first to decide what should be the attributes and their weightings. From the reviewing results, three groups of attributes were proposed in the EB-FSRS. These are the passive building construction, active fire protection systems (fire services installation), and key risk parameters, all following the local fire safety requirements. The concept is similar to those equivalent concepts on fire safety parameters of the National Fire Protection Association–Fire Safety Evaluation System (NFPA-FSES). But the EB-FSRS is not a “trade-off” exercise. Thirty-seven old high-rise buildings were rated by studying their architectural features, interior details, and fire safety provisions. Scores under EB-FSES and NFPA-FSES are also compared.     

Accommodating discontent: youth,conflict and the housing question in Hong Kong

Young people across many societies face growing problems in making the transition from the parental home to independent living. Rising house prices and the lack of affordable alternatives to home ownership is most commonly blamed. This paper explores these issues in relation to young people in Hong Kong. The paper argues that the housing question in Hong Kong has distinct local characteristics and cannot be disconnected from wider political and economic tensions. It also shows that the housing choices and views of young people are shaped by more than issues of cost and access. The paper draws on a unique data-set which explores the attitudes and expectations with regard to housing among young people in Hong Kong. Addressing the housing problem is widely regarded as a political priority and essential to maintain social cohesion. However, political imperatives and economic interests are pulling in different directions.     

构建“深港双城”,成就大珠三角

香港回归祖国10余年来,经历了巨大的变迁,当前也面对一系列的挑战和机遇。本文回顾了深港合作的历程,通过对区域合作、跨界治理理论以及欧盟空间一体化实践的借鉴,总结深港两地在规划内容、规划过程、规划实施三个方面构建"深港双城"的路径,揭示城市规划作为空间策略,为实现大珠三角地区的区域合作与跨界治理提供了有效的协调机制,为"一国两制"背景下深港两地的共同发展与持续繁荣提供了重要保障。     

港岛城市剖面

文章借用建筑学上的剖面概念,将其应用到城市尺度的形态分析和空间解读上。作者选取香港中环地区的中环至半山由自动扶梯系统覆盖的城市区域,作为诠释这一概念的具体案例。建筑剖面的传统意义被移植至城市剖面中,即在某一方向上剖切实体之后,通过观察剖切面上空间元素之间的关系,探寻彼此的内在结构,乃至这种城市结构空间背后的特殊历史过程和社会推力。香港岛的地理特征和100多年来城市化过程所形成的带状城市分布使得港岛具有剖面性格,而中环至半山的自动扶梯系统提供了一条重要的剖切线索。通过剖面方法解析,作者希望在城市形态学的分析方法上有新的突破。     

香港客家历史建筑简述

清初,清政府为了防范明遗臣郑氏反叛,厉行迁海政策,强令香港全区居民内迁五十里。到康熙八年(1669年),朝廷才许展界,因原居民迁回者少,康熙二十三年尽复旧界后清政府遂行奖励客藉居民入迁之策,大部分最后定居于今香港新界地区,因此具客家特色的传统建筑也相继建立。该文将简介其中的围屋及围村、祠堂和书室这三种建筑类型,并举例以说明其形式及功能。     

从香港盛会看丝绸收藏和研究的国际化趋势

中国古代丝绸文物展和中国古代丝绸学术讨论会首次在香港举行。这次盛会汇集了世界各地丝绸史研究专家，从中了解到，对中国古代丝绸的收藏已受到国外收藏家的重视，同时对中国丝绸史的研究近年来也方兴未艾，呈现出一种国际化的趋势。     

香港新市镇与郊野公园发展的空间关系

香港新市镇与郊野公园两者之间在至少三个方面存在着紧密的空间关系:发展时机上互相呼应,土地利用上互相制约,功能发挥上互为补充.目前,新市镇与郊野公园在构建香港城市空间框架方面共同扮演着重要角色,在促进集约型城市土地利用模式的形成方面意义重大,这也为内地很多城市提供了一种提高土地利用效率、完善城市综合功能、满足居民游憩需求的新途径.     

面向水环境改善的城市河网动态水环境容量

为掌握城市河网动态水环境容量变化规律,构建了基于“空-地-水”一体化模型体系的城市河网动态水环境容量计算模型,以粤港澳大湾区惠州市金山湖流域为研究区域,定量核算了2017年金山湖流域COD和TP动态水环境容量。结果表明,模型模拟的流量、COD和TP浓度率定、验证的相对误差均在14.04%以内;2017年,金山湖流域COD和TP水环境容量整体呈先增大后减小的趋势,受降雨影响显著,逐日容量变化范围分别为238.55~3 027.49 kg/d和3.73~58.02 kg/d;枯水期水环境容量较小且与降水量负相关;丰水期的大雨或暴雨时期水环境容量明显提升,中小雨时期COD容量与降水量负相关,TP反之;保障生态基流能明显改善容量不足的问题,全年动态生态流量保障对金山湖流域水质达标率提升效果明显。
