우리나라는 급격한 경제 발전과 함께 빠르게 도시화가 진행되었다. 하지만 도시화가 진행됨에 따라 불투수면적의 증가로 인해 도시지역 침수에 대한 위험이 야기되고 있다. 배수관망 체계는 지역 내의 강우를 빠르게 배출하는데 목적을 두고 발전해 왔다. 이러한 노력에도 불구하고 서울시는 2010년, 2011년과 같이 반복적인 침수로 인명과 재산 피해를 겪고 있는 실정이다. 본 연구에서는 2010년과 2011년을 기준으로 침수된 서울시 100개의 유역을 선정하고 깁스모형을 적용하여 침수지역을 중심으로 한 배수관망체계의 특성을 분석하였다. 이와 함께 각 유역의 IA(Impervious Area)와 DCIA(Directly Connected Impervious Area)를 근거로 불투수면적의 공간적 분포 특성도 분석하였다. 깁스모형을 이용한 네트워크 특성과 불투수면적의 공간적 분포 특성을 근거로 침수지역과의 상관관계를 분석하였다. 이를 바탕으로 도시 지역의 배수관망의 효율성을 판단하고 지역 특성에 최적화된 배수관망체계를 구축하는데 도움이 될 것이라 기대된다.

A lot of city have different characteristics in their location, space and environment each other. These characters are the factors showing inherent placeness of each space, and those factors should be reflected sufficiently in urban planning and development. Nonetheless, there are many parts that are not actually reflected in the plan, and this creates a space of unexpected arming. Especially, port area in a port city has strong characteristics of culture, history, geography and environment of the city concerned so it must make more creative and unique space. Therefore, it is considered that not only the physical factors but also the social factors should be actively reflected to highlight the place character of the port space. In this paper we are to construct the factors forming the placeness of port space based on the Form Based Codes rising as a flexible urban planning method in order to avoid rigidity of existing use district zoning system, and establish the placeness character of each port area.

Unlike in the past, port space in modern society not only serves to meet port functions but also other functions such as housing, leisure, and sightseeing. As a result, more and more people are turning into a dense space. Port space, on the other hand, is also a space vulnerable to disasters which can be attributed to geographical and environmental characteristics. Despite the sensitivity if the issue, in Korea disaster prevention and urban planning have not been clearly established. Therefore, there is a need to provide safety and disaster preventive measures in urban planning considering the characteristics of harbor space.

In this study, the change characteristics of urban spatial structure in Daegu were analyzed connecting with urban planning for efficient urban management. Urban development process from 1970 to 2010 in Daegu was analyzed utilizing Getis-Ord $G_i^*$ methodology, a spatial statistical method, and it was identified that Daegu was in the stage of disurbanization. However, as Daegu orients multi-nuclei city, it was difficult to explain the stage of urban development after disurbanization in 2000. Accordingly, to analyze detailed changes in spatial structure in multi-centric areas after 2000, population, land price and employment factor changes were analyzed using Bachi Measurement. According to analytical results, multi-centralization process has been continued in Daegu. Urban core area and Chilgok area showed spatial structure change into distribution process, Ansim area into concentration process, and Seongseo and Talseo area into concentration and distribution process. Therefore, urban planning considering the regional characteristics are needed for efficient urban management.

This study examines changes in commercial space in Seoul from 1999 to 2016 by investigating operating periods of commercial businesses. This study finds that the characteristics of spatial changes in commercial districts are classified by the following two major points. First, the traditional CBD and Yeongdeung-po commercial districts show that both ages (survival duration) of operating commercial businesses and operating periods of market-exit businesses have changed to become longer than the average values of the two business types in Seoul. In contrast, the Gangnam and the Mapo commercial districts show that the operating periods of survived and closed commercial businesses have changed to become shorter over time. The difference suggests that survival-exit relations of businesses are closely related to the characteristics of each commercial district. In addition, this study shows that each commercial district has experienced dynamic changes in the intensity of commercial activities and the hierarchy of commercial space. Finally, this study indicates that public policies for commercial space should consider survival-exit dynamics of commercial activities in commercial districts.

This study analyzed wind flows based on spatial and geomorphological characteristics of Daegu Metropolitan City. A three-stage analysis was performed, starting with a comparison of meteorological relationships between local wind direction (synoptic wind) and local wind flow. In the second stage the study area was subdivided into districts and suburban districts to analyze the relative change of local wind flow. In stage three, the formation of wind corridor for local wind flow, wind flow for the entire urban space, and spatial relationships between flows were verified comparatively using KLAM_21. Three results are notable, the first of which is a low correlation between synoptic wind of a region, and local wind, flow in terms of meteorology. Secondly, observations of local wind flow at five downtown districts and two suburban districts showed that there were diverse wind directions at each measurement point. This indicates that the spatial and geomorphological characteristics of areas neighboring the measurement points could affect the local wind flow. Thirdly, verifying the results analyzed using KLAM_21, compared to Atomatic Weather System(AWS) measurement data, confirmed the reliability of the numerical modelling analysis. It was determined that local wind flow in a city performs a spatial function and role in ameliorating the urban heat island phenomena. This indicates that, when an urban planning project is designed, the urban heat island phenomena could be ameliorated effectively and sustainably if local wind flow caused by immediate spatial and geomorphological characteristics is confirmed systematically and techniques are intentionally applied to connect the flows spatially within areas where urban heat islands occur.

최근 이상 기후로 인하여 홍수피해가 많이 발생 하고 있다. 특히 도시유역의 도시화로 인해 불투수면적이 증가하여 내수 침수도 증가하였다. 이로 인하여 재산피해와 인명피해가 증가하면서 전 세계적으로 홍수 저감 연구가 진행 되고 있다. 강우의 시 공간적인 특성을 파악 하여 강우 사상을 정의 한다면 도시홍수 저감 에 있어 도움이 될 것이라 판단된다. 우리나라 서울 지역의 설계 강우량을 산정하기 위해 서울기상청에서 제공하고 있는 ASOS(Automated Surface Observing System) 를 사용해 왔다. 하지만 ASOS을 사용하게 되면 강수량의 공간 특성을 고려하기 어렵지만 AWS(Automatic Weather Stations) 는 세밀한 관측망을 가지고 있어 공간적 특성을 고려할 수 있다. 본 연구에서는 서울 기상청에서 제공하고 있는 강우 자료의 20개년 연속된 강우자료를 통해 강우자료를 구축 하였다. 서울지역의 유역을 선정하였으며 도시유역 강우-유출 해석에 많이 사용되는 EPA-SWMM 모형에 ASOS 와 AWS 강우자료를 적용하여 유출 분석을 하였다. 이러한 자료를 바탕으로 공간 특성 분석을 실시하여 더욱 세밀한 설계 강우량 산정에 도움을 있을 것으로 판단된다.

This paper aims to investigate changes in the characteristics of urban spatial structure in Korea by regional groups and city size between 2000 and 2010. The characteristics of urban spatial structure is analyzed by Clark's population gradient curve in this paper. Therefore key parameters in population gradient function, such as population density gradients and population density in CBD represent the characteristics of urban spatial structure. The result shows that most of cities in Korea have experienced suburbanization rather than concentration, but small-size cities have experienced concentration during the period.

Purpose: This study aims to suggest new strategy of planning water management and land use in response to abnormal weather which allow waterfront to be the cities through the experience of Netherlands resilient project. Method: A planning direction is developed based on Dutch national resilient policy and strategy as well as resilient theory of technical and social aspects, focusing on a new waterfront development that responds to abnormal weather. Results: The water control strategy, for flexibly responding to the sea level rise and flooding caused by the climate change through the experience of Dutch resilience, is as follows: 1)Customized prevention plan according to the local property 2)Creating spatial planning by considering disaster risk level and fragility 3)Establishing urban planning by considering the flood risk level. Conclusion: A new urban development method, particularly a resilience strategy based on the waterfront space where is most vulnerable to climate change, is required to cope with the abnormal climate beyond the conventional planning.
