Fractal Characteristic Evolution of Coastal Settlement Land Use: A Case of Xiamen, China

Coastal settlements in urban areas show certain degrees of spatial complexity. Understanding the evolution law of fractal settlements is practically important for marine engineering and urban planning. In this paper, we investigate the fractal evolution of coastal settlement land use based on fractal theory. The fractal dimensions of the land uses for three typically coastal settlements in Xiamen city, China, are obtained to quantify their spatial complexity. The results reveal the fractal characteristics and regional differences of the coastal settlements. Furthermore, nonlinear modeling is applied to describe the fractal dimension evolution of the coastal settlement land uses from 2000 to 2018. Three settlements in rapid urbanization show different nonlinear evolution equations of the fractal dimension due to their different land uses. This study might provide a theoretical basis for understanding the fractal characteristic evolution of coastal settlements in urban areas and show its potential application in urban geography.

High Ground, Low Ground: Explorations in Topography and Neighbourliness in Coastal Dune Settlement

<p>The desire to live close to the ocean often brings about settlement that sprawls along the beachfront, parallel to the coastline. This settlement structure is problematic as it diminishes the importance of community while exposing beachfront housing to coastal hazards. The coastal dune settlements of Waikanae and Paraparaumu, where this research has been undertaken, exhibits this problematic settlement structure. Using these sites as a case study, the research seeks to re-examine the New Zealand coastal land settlement formation. It explores what could happen if the current coastal settlement pattern re-organised as a more social structure? The research is investigating an approach to settlement through re-examining the idea of neighbourhood by looking at its whole relation to the coastal dune topography, ecology, and wider landscape relations. However, not only does this research look at the social potentials of coastal settlement but how disaster planning can become a device to achieve this outcome. Essentially, it aligns itself with the attitude that flooding and coastal hazards should not just be looked at as an engineering problem but an opportunity to alter the way in which we settle coastlines in a way that builds community.</p>

Coastal Settlement Behavior Setting in Kampung Blok Empang, North Jakarta

The purpose of the study was to find out behavior setting and its elements in Kampung Blok Empang. Kampung Blok Empang which is located on the coast of North Jakarta has a port setting and is bypassed by tourist access to the Kepulauan Seribu, so it is interesting to know how the behavior setting in this village is. Data collection is done by field observation and secondary data. The approach used in this research is deductive-qualitative with the research variables in the form of behavior setting. The Behavior Setting in Kampung Blok Empang is shown by how the setting of the urban village located in the port area affects most of the relationships between physical objects and the behavior of residents in the village. The best performance of behavior setting in Kampung Blok Empang is shown in the open space because its milieu-behavior interdependency. It is shown by the repetitive behavior in this specific milieu. The spatial Pattern type is formed by the collective activity of residents and the sea condition. They were characterized by the repetitive activities within their economic and social aspects.

Pengaruh Bentuk Pola Persebaran Permukiman Penduduk terhadap RTH di Kampung Tua Tanjung Riau

The undirected distribution pattern of settlements tends to cause irregular building arrangement patterns. Coupled with the increasing building density level, the availability of open space is at risk of decreasing. The coastal settlement of Kampung Tua Tanjung Riau in Batam is a vivid example of this kind of settlements development issue. Through descriptive-qualitative research methods, the form of distribution pattern of settlements was observed from the street layout and buildings location. Subsequently, it can be identified and analysed that the longitudinal distribution pattern of settlements in Kampung Tua Tanjung Riau affects the availability of green open space in the area which is considered inadequate. This research is expected to be taken into consideration by related agencies including the government in overcoming the existing problems in Kampung Tua Tanjung Riau.Keywords: Distribution Pattern of Settlements, Green Open Space, Kampung Tua Tanjung Riau Abstrak. Bentuk pola persebaran permukiman penduduk yang tidak terarah cenderung menyebabkan ketidakteraturan pola penataan bangunan. Ditambah dengan tingkat kepadatan yang semakin meningkat, ketersediaan ruang terbuka beresiko menurun. Permukiman pesisir Kampung Tua Tanjung Riau di Kota Batam, merupakan salah satu contoh nyata permasalahan perkembangan permukiman tersebut. Melalui metode penelitian kualitatif deskriptif, bentuk pola persebaran permukiman ditinjau dari pola jalan dan lokasi hunian. Kemudian, dapat diidentifikasi dan dianalisis bahwa bentuk pola persebaran permukiman yang memanjang di Kampung Tua Tanjung Riau mempengaruhi ketersediaan RTH (Ruang Terbuka Hijau) di kawasan tersebut yang notabene dinilai masih kurang memadai. Penelitian ini diharapkan dapat menjadi bahan pertimbangan instansi terkait termasuk pemerintah dalam mengatasi permasalahan yang ada di kawasan Kampung Tua Tanjung Riau.Kata Kunci: Pola Persebaran Permukiman, Ruang Terbuka Hijau, Kampung Tua Tanjung Riau

Variação das dunas no Balneário Barra do Chuí, extremo sul do Brasil, entre 2005-2018

As dunas costeiras são feições naturais formadas a partir das praias arenosas, devido a interação do vento, areia e vegetação. No entanto, a ação humana torna-se uma variável cada vez mais relevante em sua dinâmica, ocasionando problemas ambientais. O presente trabalho tem como objetivo quantificar e caracterizar, a partir de uma série temporal de imagens orbitais no intervalo entre 2005 e 2018, a mobilidade das dunas no Balneário Barra do Chuí – RS, especificamente a variação na base das dunas frontais. O intuito é verificar processos de erosão e sedimentação na orla do balneário, bem como a variação do limite do reverso do campo de dunas, onde se encontra a área urbana edificada do balneário. A metodologia foi empregada a partir de imagens orbitais adquiridas no software Google Earth Pro® e técnicas realizadas nos softwares ArcGIS 10.3.1® e ERDAS Imagine 2013®. A variação das linhas de costa analisadas foi obtida a partir do Método do Polígono de Mudança, por meio de uma linha de controle aplicada aos limites praia-duna frontal e reverso da duna. O Balneário Barra do Chuí, no período estudado, apresentou predomínio de taxas de erosão das dunas frontais, onde depósitos pleistocênicos estão sendo diretamente trabalhados pela ação marinha. O reverso das dunas apresentou tendência de avanço em relação à retroterra. Constatou-se que em alguns locais o transporte eólico de sedimentos está soterrando algumas residências.

Foredune variation in the Barra do Chui coastal settlement, southern Brazil, between 2005-2018ABSTRACT Foredunes are natural features formed from sandy beaches, due to the interaction of wind, sand, and vegetation. However, human action becomes an increasingly relevant variable in its dynamics, causing environmental problems. The present work aims to quantify and characterize, from a time series of orbital images in the interval between 2005 and 2018, the dune mobility in the Barra do Chui coastal settlement, specifically the variation in the base of the frontal dunes, in order to check erosion and sedimentation at the edge of the resort, as well as the variation of the limit of the reverse of the dune field, where the built-up area of the resort is located. The methodology was used based on orbital images acquired in the Google Earth Pro® software and techniques performed in the ArcGIS 10.3.1® and ERDAS Imagine 2013® software. The variation of the coastlines analyzed was obtained from the Change Polygon Method, through a control line applied to the frontal and reverse dune beach-dune limits. The Barra do Chui coastal settlement, in the studied period, presented a predominance of erosion rates of the frontal dunes, where Pleistocene deposits are being directly worked by the marine action. The reverse side of the dunes showed an upward trend in relation to the retrograde, in fact, in some places, wind sediment transport has already been burying some homes. Keywords: Dune-Beach Limit.
