Analysis of Tidal Prism Evolution and Characteristics of the Lingdingyang
MATEC Web of Conferences 25, 001 0 6 (2015) DOI: 10.1051/matecconf/201525001 0 6 C Owned by the authors, published by EDP Sciences, 2015 Analysis of Tidal Prism Evolution and Characteristics of the Lingdingyang Bay at Pearl River Estuary Shenguang Fang, Yufeng Xie & Liqin Cui Key laboratory of the Pearl River Estuarine Dynamics and Associated Process Regulation, Ministry of Water Resources, Guangzhou, Guangdong, China ABSTRACT: Tidal prism is a rather sensitive factor of the estuarine ecological environment. The historical evolution of the Lingdingyang water area and its shoreline were analyzed. By using remote sensing data, the evolution of the water area of the bay was also calculated in the past 30 years. Due to reclamation, the water area was greatly decreased during that period, and the most serious decrease occurred between 1988 and 1995. Through establishing the two-dimensional mathematical model of the Pearl River estuary, the tidal prism of the Lingdingyang bay has been calculated and analyzed. The hybrid finite analytic method of fully implicit scheme was adopted in the mathematical model’s dispersion and calculation. The results were verified though the method of combining the field hydrographic data and empirical formula calculation. The results showed that the main tidal entrance of the bay is the Lingdingyang entrance, which accounts for about 87.7% of the total tidal prism, while Hong Kong’s Anshidun waterway accounts for only 12.3% or so. Combining the numerical simulations and the historical evolution analysis of the water area and tidal prism, and compared with that in 1978, it showed that the tidal prism of the bay was greatly decreased, and the reduced area was mainly the inner Lingdingyang bay, which accounted for 88.4% of the whole shrunken areas. -

Assessing the impacts of both natural (e.g., tidal forcing from the ocean) and human- induced changes (e.g., dredging for navigation, land reclamation) on estuarine morphology is par- ticularly important for the protection and management of the estuarine environment. In this study, a novel analytical approach is proposed for the assessment of estuarine morphological evolution in 5 terms of tidally averaged depth on the basis of the observed water levels along the estuary. The key lies in deriving a relationship between wave celerity and tidal damping or amplification. For given observed water levels at two gauging stations, it is possible to have a first estimation of both wave celerity (distance divided by tidal travelling time) and tidal damping or amplification rate (tidal range difference divided by distance), which can then be used to predict the morphological changes 10 via an inverse analytical model for tidal hydrodynamics. -

Abstract Spatial distribution of chlorinated hydrocarbons [chlorinated pesticides (CPs) and polychlorinated biphenyls (PCBs)] and poly- cyclic aromatic hydrocarbons (PAHs) was measured in riverine and estuarine sediment samples from Pearl River Delta, China, collected in 1997. Concentrations of CPs of the riverine sediment samples range from 12 to 158 ng/g, dry weight, while those of PCBs range from 11 to 486 ng/g. The CPs concentrations of the estuarine sediment samples are in the range 6–1658 ng/g, while concentrations of PCBs are in the range 10–339 ng/g. Total PAH concentration ranges from 1168 to 21,329 ng/g in the riverine sediment samples, whereas the PAH concentration ranges from 323 to 14,812ng/g in the sediment samples of the Estuary. Sediment samples of the Zhujiang River and Macao harbor around the Estuary show the highest concentrations of CPs, PCBs, and PAHs. Possible factors affecting the distribution patterns are also discussed based on the usage history of the chemicals, hydrologic con- dition, and land erosion due to urbanization processes. -

2019 International Conference on Computer Science, Communications and Big Data (CSCBD 2019) ISBN: 978-1-60595-626-8 Problems and Measures of Passenger Organization in Guangzhou Metro Stations Ting-yu YIN1, Lei GU1 and Zheng-yu XIE1,* 1School of Traffic and Transportation, Beijing Jiaotong University, Beijing, 100044, China *Corresponding author Keywords: Guangzhou Metro, Passenger organization, Problems, Measures. Abstract. Along with the rapidly increasing pressure of urban transportation, China's subway operation is facing the challenge of high-density passenger flow. In order to improve the level of subway operation and ensure its safety, it is necessary to analyze and study the operation status of the metro station under the condition of high-density passenger flow, and propose the corresponding improvement scheme. Taking Guangzhou Metro as the study object, this paper discusses and analyzes the operation and management status of Guangzhou Metro Station. And combined with the risks and deficiencies in the operation and organization of Guangzhou metro, effective improvement measures are proposed in this paper. Operation Status of Guangzhou Metro The first line of Guangzhou Metro opened on June 28, 1997, and Guangzhou became the fourth city in mainland China to open and operate the subway. As of April 26, 2018, Guangzhou Metro has 13 operating routes, with 391.6 km and 207 stations in total, whose opening mileage ranks third in China and fourth in the world now. As of July 24, 2018, Guangzhou Metro Line Network had transported 1.645 billion passengers safely, with an average daily passenger volume of 802.58 million, an increase of 7.88% over the same period of 2017 (7.4393 million). -

In Malaysia, the problem issues are related to traffic congestion and many user cars on the roadway in daily lives. One alternative mode of using a rail network is commuter, LRT, Monorail, MRT and ETS. Therefore, the Geographic Information System (GIS) technology is then used to map and produce the railway networks history and developments in urban public transportation (UPT). The goal of this research is to identify the heatmap trends of the Klang Valley railway stations which included Kuala Lumpur as urban public transport sectors. It was based on the OSM image layer from the year 1990 to 2019 and studied the growth of railway networks through a polyline pattern analysis. -

The Suzhou National High-tech District tram was investigated as a J6 case study. Two key findings are highlighted. Firstly, the new tramway was routed along the “path of least resis- P2 tance”–avoiding dense urban areas, to reduce conflict with cars. Secondly, regarding urban transport integration, R3 four perspectives were evaluated, namely planning and design, service operation, transport governance and user R4 experience. Findings show insufficient integration in the following aspects, namely tram and bus routes and services, O2 fares on multi-modal journeys, tram station distribution, service intervals, and luggage auxiliary support. The paper Keywords: argues there is a need for a critical review of the role of tram and for context-based innovative policy reform and Tram governance that could possibly facilitate a successful introduction and integration of tram into a city. Urban development Urban transport integration Suzhou China 1. Introduction so instead began planning tram networks. There has been relatively little research examining how new trams have been introduced into cities and The past decade has seen rapid development of urban rail systems in whether these tramways provide an effective alternative to private car use. -
