  • The objects of this study are to identify values of criterion(vii) and to consider a possibility of application of criterion (vii) of UNESCO World Heritage to Mt. Seoraksan Natural Reserve based on the analysis of the concept of criterion (vii) and justifications of World Heritage sites under criterion (vii). According to the analysis results of 114 Natural Heritage sites under criterion (vii) listed between 1978-2015, detailed values of the criterion and their applied cases were categorized into 10 values. Based on this category, values were drawn that could be applied to Mt. Seoraksan and support the justification of criterion (vii) in three aspects. First, the value of visuality could be applied to Mt. Seoraksan due to its abundance of Scenic Sites, which means it has been recognized as an area with natural beauty by government. Second, the value of comprehensiveness of geomorphological landscape could be applied to Mt. Seoraksan in that it shows all kinds of granite landform in a relatively limited area. Finally, the value of comprehensiveness of geomorphological landscape could be again applied due to its overall mountainous river landscape.

  • This paper presents the systematic approach to positively skewed shape of instantaneous unit hydrograph (IUH), that is one of the universal features of hydrologic response function. To this end an analytical expression of statistical moments for IUH is derived within the framework of geomorphologic instantaneous unit hydrograph (GIUH) theory and quantified according to the concept of hydrodynamic, geomorphologic and kinematic heterogeneity. There is a big scale difference between hillslope and channel flow path system. Although the former has the much smaller level of scale its variation coefficient tends to be higher and coefficient of skewness has the different trend than the latter. The shape of IUH is likely to be much more affected by kinematic heterogeneity rather than hydrodynamic heterogeneity and its combined effect with geomorphologic heterogeneity is the major cause of skewing hydrologic response function. Statistical features of hillslope and channel flow path can be transferred into hydrologic response function in the form of dimensionless statistics and their relative importance forms the general shape of hydrologic response function.

  • This paper aims to investigate the value in culture, history and ecology of the Mt. Palgong. It attempts to build the strategy for making use of The Mt. Palgong by literature survey, interview, and field survey. The main results are as follows: 1) The boundary of physical geography of the Mt. Palgong is classified into two. The boundary of the Mt. Palgong limits to granite mass block in a narrow sense, while in a broad sense, the boundary of the Mt. Palgong includes a contact aureole to be bordered on the Mt. Palgong granite mass block. The boundary from a cultural viewpoint limits to Daegu city(excluding Dalseong county) and Gyeongsan city, Yeongcheon city, Gunwi county and Chilgok (Dongmyeong-myeon, Giseong-myeon) in Gyeongbuk province. 2) In the geological boundary, one of the south-west slope is clearer than that of the north-east slope of the Mt. Palgong. The landforms such as tor, sheeting joint and gutter are well developed as a whole. Mountain landform such as boulder stream, polygonal cracking is relatively well developed on the south-west slope, while river landform is relatively well developed on the north-east slope of the Mt. Palgong. 3) It is necessary to develope various masterpiece of interesting stories related to Mt. Palgong in order to make the Mt. Palgong excellent tour complex. 4) It is desirable to designate the Mt. Palgong as a national park for systematic management. A master plan should be ultimately designed to raise brand value of Daegu city, and make good identity of the city by restoring 'The Mt. Palgong Jecheondan' and registering 'Gatbawi' as world heritage. 5) It is reasonable that the method of development in The Mt. Palgong should be based on the pattern of 'slow life town'. 'The Mt. Palgong museum' will then be designed to give visitors all the informations on The Mt. Palgong.

  • In the wartime, aircraft carrying out a mission to strike the enemy deep in the depth are exposed to the risk of being shoot down. As a key combat force in mordern warfare, it takes a lot of time, effot and national budget to train military flight personnel who operate high-tech weapon systems. Therefore, this study studied the path problem of predicting the route of emergency escape from enemy territory to the target point to avoid obstacles, and through this, the possibility of safe recovery of emergency escape military flight personnel was increased. based problem, transforming the problem into a TSP, VRP, and Dijkstra algorithm, and approaching it with an optimization technique. However, if this problem is approached in a network problem, it is difficult to reflect the dynamic factors and uncertainties of the battlefield environment that military flight personnel in distress will face. So, MDP suitable for modeling dynamic environments was applied and studied. In addition, GIS was used to obtain topographic information data, and in the process of designing the reward structure of MDP, topographic information was reflected in more detail so that the model could be more realistic than previous studies. In this study, value iteration algorithms and deterministic methods were used to derive a path that allows the military flight personnel in distress to move to the shortest distance while making the most of the topographical advantages. In addition, it was intended to add the reality of the model by adding actual topographic information and obstacles that the military flight personnel in distress can meet in the process of escape and escape. Through this, it was possible to predict through which route the military flight personnel would escape and escape in the actual situation. The model presented in this study can be applied to various operational situations through redesign of the reward structure. In actual situations, decision support based on scientific techniques that reflect various factors in predicting the escape route of the military flight personnel in distress and conducting combat search and rescue operations will be possible.

  • A validation study has been performed using the Soil and Water Assessment Tool(SWAT) model with data collected for the Neponset River watershed, which includes roughly 130 square miles of land located southwest of Boston. All of this land drains into the Neponset River, and ultimately into Boston Harbor. This paper presents the methodology of a SWAT model. The calculated contribution of the baseflow to the streamflow is far too high whereas the interflow is strongly underestimated. Alternatively, the modified and calibrated model yields far better results for the catchment. The modification allows hydrological processes to be modeled while not restraining the applicability of the model to catchments with other characteristics. For this study, the SWAT 2005 model is used with ArcGIS 9.1 as an interlace, and sensitivity analysis is performed to provide rough estimated values before adjusting sensitive input parameters during calibration period.

  • 도시 개발에 의해 우수의 불투수지역 확대, 하천부지의 축소, 산림 및 유수지의 감소 등이 급속히 진행되어 하천유량의 변화, 지하수위의 저하, 용수의 고갈, 생태계의 파괴 등이 발생되어 왔다. 도시지역은 도시형 수해발생, 갈수시의 급수안전도 지하, 평시 하천유량의 감소, 공공수역의 수질악화, 지하수 오열 등 여러 가지 문제에 직면하고 있다. 이러한 문제들은 서울의 경우도 예외는 아니며 청계천 복원 사업과 더불어 그동안 방치되었던 도시유역의 물순환 체계를 분석할 필요가 있다. 본 연구에서는 SWAT 모형을 이용하여 도시하천 유역의 물순환을 해석하였다. SWAT모형은 미국 농무성 농업연구소(Agricultural Research Service, ARS)에서 개발된 모델로서, 내규모의 복잡한 유역에서 장기간에 걸친 다양한 종류의 토양과 토지이용 및 토지관리 상태에 따른 물과 유사 및 농업화학물질의 거동에 대한 토지관리 방법의 영향을 예측하기 위해 개발되었다. SWAT 모형은 물리적 이론에 근거한 연속모형으로 준분포형 (Semi-Distributed) 모형이다. 본 연구는 도시하천 유역의 물순환체계 변동을 고려한 물순환 정상화 기술을 개발하기 위한 기초단계로서, 청계천 유역에 내해 모형을 적용하였다. 청계천은 중랑천의 제1지류인 지방2급 하천으로 유역면적 $50.96km^2$, 유로연장 13.75km이며, 2003년 7월부터 ,5.9km의 본류구간에 대한 복원공사가 진행 중이다. 적용유역의 수문${\cdot}$기상${\cdot}$지하수 자료는 1993널 1월 1일 $\~$ 2002년 12월 31일까지의 서울 기상청 자료를 이용하였으며, 지형, 토양, 토지이용 자료는 기존에 구축된 GIS 자료를 이용하였다. 모형 적용결과, 도시하천 유역에 대한 SWAT 모형의 적용성을 확인할 수 있었으며 유역의 물순환계를 구성하는 강수, 지표수, 토양수, 지하수 및 하천수 등의 상호 관계 분석을 통해 장기간의 유역 물순환체계 변화를 분석할 수 있었다.
