This study attempts to analyze the drainage system of the Buk-Han River basin with the purpose of examing the characteristics and presenting the data for systematizing rivers in Korea. The Drainage system is analyzed according to Bifurcation ratio and Length ratio. The research is based upon analysis of 1 : 250,000 topographical map coverage. The results are as follows: (1) The main stream is found to be 6th order. The Bifurcation ratio (N_1/N_2) is determined to be 4.1 and the Length ratio(L_2/L_1), 1.18. (2) Correlation between order and number which is plotted on the semilog paper shows characteristics of natural stream systems. (3) Correlation between order and length expresses that the junction of the 5th order leans to the lower stream.(4) The average drainage density of Buk-Han River Basin is 381m/㎢.

Mt. Waryong situated on the western part of Daegu City is a monadnock (299.6m), which is formed erosional basin in the center of it. The main aim of this study is to clarify formation processes through analyzing the geological and geomorphological characteristics of study area. The summary of the characteristics are as follows; 1. The study area had been formed sedimentary rocks of Kyoungsang series at the Mesozoic era, and later, the intrusion of Bulguksa granite had occured. 2. In the center of the area, there is distributed Bulguksa granite, as it is the plutonic rocks which is weak to weathering that was formed erosional basin. 3. The surroundings of the area is formed ridge that is consist of metamorphic rocks(Hornfels) which is strong to weathering. And we can find rockfall zone of breccia here and there at the upper-slope. 4. As the result, the landform of mountain block is formed concave like 'U' letters open to northward. From the characteristics mentioneo above, we can classify formation processes in the Waryong mountain as follows; 1. Pre-forming period of the mountain. 2. The intrusion of granite and contact metamorphism period. 3. Differential erosion period.

The result of this study are as follows; 1. A characteristic of the distribution 1) Considering as the distribution of a distance, apartment houses are in close order in a boundary of 3 Kilometers. 2) Considering as sectors, apartment houses consist of sector 1, 8, 5, and 6, these are the same regions as residental ones on the regional structure in the east, the west and south of Daegu city. 2. A characteristic of the spatial development 1) Period 1 has a dot-formed distribution. 2) In period 2, the private investment is began, and apartments are nearly approached towards C.B.D. that has centralization of the vacation and residence. On the other hand, they are developed as outward sprawling of residence. On the other hand, they are developed as outward sprawling of decentralization of vacation and residence. 3) Period 3 shows the tendency of spatial variation that develops agglomeration around a core of the apartments period 2. 3. A characteristic of the attribute 1) The price of the apartment houses are raised and their sizes are enlarged year by year. And the most of them are their own houses. 2) Many owners are mainly the productive age people that have vigorous activity in the economical and social field. Therefore, they are the persons with a higher education, and the most of them work as professional, technical, and clerical workers. They also consist of nuclear family system. 4. A characteristic of the condition of location 1) In view of topographical condition, apartment houses are in the low level lands, as for traffic condition, time distance(10 to 15 minutes) and spatial distance (2 to 4 Kilometers), they are locate in centralization of the vacation and residence. 2) As a whole, the urban facilities are good, but apartment houses have not a few weak points being far from markets and schools. Therefore, supplement of these things are keenly demanded.

遠隔探査技法을 利用한 金海平野의 地表環境分析

金又寬,曺明姬 慶北大學校 1991 論文集 Vol.51 No.-

Various techniques of remote sensing are applied to identify types of land cover on the Kimhae Delta Plain from its Landsat TM inage of November 21, 1984. The techniques used here are evaluated in terms of their effectiveness and limitation in land cover classification. And then examinations are made of distributional characteristics that individual land covers have over the area. The rssults of an effectiveness evaluation of remote sensing techniques in this study are as follows. 1. A Visual analysis of individual spectral bands shows that targets in the area are more easily distinguished in one band than in another one. 2. An analysis based on false color composite images shows that the combination of bands 4-3-2 is most effective for classifying large-scale land covers like manmade structure or vegetation ect. And band combinations of 5-4-3, 5-3-2, or 5-4-2 are complementarily needed for a detailed classificaton of vegetation or man-made structure. 3. Density slicing is found a useful technique to classify in detail water or soil of different quality. Especially, its application to the band 5 image shows a better result than that to any other bands. But density slicing is found inadequate for the area which has many terrestrial elements of subtle spectral difference mixed wildly. 4. A Supervised classification using the maximum likelihood method indicates that : 1) the band combination of 5-4-3 proves most effective in the land cover classification, which results in 16 different classes. 2) supervised classification provides more distinguishing accurate and interpretable results, and 3) agricultural produces such as green onion, radish/cabbage, and parsley are readily recognize, and for the first time it is found possible to distinguish between fresh and salt water, and between non-saline and saline soil. Distributional characteristics of individual land covers are as follows. 1. The Kimhae Delta Plain has an individual vegetable produce to concentrate over some specific areas. Green onion forms a large patch throughout Myungho-Do especially by covering its beach ridge of sandy soil in the coastal delta. Radish/cabbage centers around the natural levee along the Chukrim-Gang and the Pyongchon-Gang. And parsley forms a large patch in the Pombangri area. 2. Non-saline soil is located in paddy fields of the upper delta and its surrounding area, whereas saline soil is found in those of the lower delta. 3. The Pyongchon-Gang, Chukrim-Gang and Macdo-Gang are of fresh water, which have underwater facilities for protection againt salt water reflux in their mouths. In the year of 1984 when the Naktong River did not have such a facility, salt water appeared far inland along its main stream.

지형재해에는 화산재해, 지진재해, Land Sliding, 홍수재해, 해안침식재해 등 여러가지가 있으며 직접, 간접으로 많은 재해를 발생케 하고 있다. 일반적으로 재해의 발생은 자연적 조건에 기인하는 것으로 생각하기 쉬우나 실은 사회적 조건과 복합된 상태에서 발생하는 것이다. 본고에서는 사회적인 것은 약하고 자연적 조건 중 토석류로 인한 재해에 대하여 약술해 보기로 한다. 한반도에 있어서 재해발생과 관련이 깊은 것 중 자연조건에 해당되는 것은 주로 지형, 지질, 기상 등을 들 수 있고 그 중에서도 지형은 지질이나 기상과 밀접한 관계를 가지면서 상호지배되는 면이 많다. 따라서 재해발생의 원인을 생각할 때는 어느 개개의 인자적인 조건을 들기보다는 제조건을 동시에 생각하는 것이 현실적이라 볼 수 있다.
