홍수방어에 대한 과거의 연구들은 대부분 대규모 하천 유역에 집중되어왔으나, 최근 경제력의 향상을 통한 산악지역으로의 레져영역의 확대는 돌발홍수 발생에 대비한 추가적인 방재활동의 필요성을 증대시키고 있다. 따라서 본 연구에서는 돌발홍수로 인한 인명 및 재산 피해를 최소화하기 위하여 다양한 지표들을 고려하여 산지유역에서의 돌발홍수 발생 위험을 평가하기 위한 기법을 제시하였다. 이를 위해 본 연구에서는 돌발홍수 위험지역을 평가하기 위하여 지역특성, 강우특성 및 지형특성을 평가지표로서 선정하였으며, 이들 요소들의 특성을 평가하여 돌발홍수 경보 시스템 설치를 위한 적정 지점을 평가 및 선정하는 기법을 제안하였다. 제안된 평가 기법은 봉화군에 적용되었으며, 이를 통하여 제안된 기법의 적용 과정을 설명하였다.

An extensive study of the vegetation characteristics of the Hamersley Ranges, a mountainous desert area of north-west Australia, facilitated the comparison of plant species diversity measures with mountainous deserts of other parts of the world. Alpha diversity was defined as the number of species co-existing at local scales and was found to average 18 species per 0.1 ha for the Hamersley Ranges. This was found to be similar to seven other mountainous deserts in North and South America, and southern Africa. Variation in alpha diversity between these deserts was found to considerably lower than within deserts, suggesting that local processes control species richness at local scales. Beta diversity, defined here as turnover in species composition at various spatial scales, can be measured in many ways. For the Hamersley Ranges, Wilson's β ranged from 1.2 to 1.6 for five sites along a topographic gradient, whereas Whittaker's β between different plant communities was found to average 0.93. Comparable data was not found for other desert areas, but comparisons to non-desert areas suggest beta diversity within landscapes is relatively high and is likely to reflect the considerable landform heterogeneity of the Hamersley Ranges. 55∼70% of species were shared between different landscapes of the Hamersley Ranges; comparisons to other regions suggest beta diversity at this scale is relatively low. Gamma diversity, the number of species over large spatial extents, was successfully compared using regression analysis of the log-log species - area relationship. This revealed that the northern Sonoran desert has significantly less species than the Nama (inland) Karoo and Hamersley Ranges over medium spatial extents, but species numbers were similar at a regional scale. Several constraints to the valid comparison of species diversity were identified, including lack of standardisation of sampling techniques, the wide range of measures employed, general lack of published data, and the influence of the various components of spatial scale on most diversity measures. Recommendations on how to improve future comparative work are provided.

태백 산지는 대체로 냉량하고 습한 편이지만, 강수량은 지역적으로 많은 차이를 나타내고 있다. 이와 같은 기후지형 환경과 관련하여 태백산지의 지형 및 토양환경은 기반암의 유형에 따라서 차이를 보인다. 북부의 금강산과 설악산 같은 화강암 분포 지역은 절리밀도의 차이를 반영하는 풍화 성향 때문에 암괴 노출이 심한 산지를 이루며, 미시령 일대의 편마암 분포 지역은 전사면이 흙으로 덮여있고 상대적으로 식생밀도가 높은 곳이다. 중부에서는 암괴 노출이 심한 타지역의 화강암산지와는 달리 박토상태지만 대체로 전사면이 흙으로 덮여있다. 이는 이 지역이 눈이 많고 서릿발 작용이 활발하여 화강암을 얇게나마 풍화시킬 수 있었기 때문이다. 남부에서는 급사면의 뾰족한 봉우리와 좁고 깊은 협곡을 이루는 석회암산지 및 완만한 사면지역의 여러 가지 용식지형이 발달한다. 이 지역에는 초본류나 관목류들이 연속성이 높게 분포하여 박토상태인 토양을 잘 보전하고 있다.

The aim of this study was to examine the selected soil chemical properties of paddy fields in different topographic areas to efficiently manage nutrient valances of the paddy fields in Jeonbuk Province. Three-hundred soil sampling sites in paddy fields were selected from the different topographic areas in Jeonbuk Province. The soil samples were collected every four years from 1999 to 2015. Soil pH and exchangeable K and Mg concentrations declined during the experimental periods. However, almost all the chemical properties were within the proper levels for paddy soil, except exchangeable Mg concentration. Distributed areas of the paddy fields with soil pH below 5.5 continuously increased, but the paddy fields with lower concentrations of soil organic matter and available $P_2O_5$ than the proper levels declined after 2007. In addition, the paddy fields with available $SiO_2$ below the proper concentration decreased from 83.3% of the total paddy fields studied in 1999 to 61.0% of the total fields investigated in 2015. The paddy fields with lower exchangeable K and Mg than the proper levels increased after 2003 whereas the fields with lower exchangeable Ca concentration decreased. Dominant landform of coastal and plain areas was fluvio-marine plains that was distributed in 53.7% and 40.9%, respectively. Local valley and fans was a dominant landform of mountainous and middle-mountainous areas, which was 51.8% and 67.6%, respectively. Dominant soil textures distributed in coastal and plain areas were silty loam and loam. Those in mountainous and middle-mountainous areas were sandy loam and loam, respectively. Soil pH was relatively higher in coastal area and the comparatively higher content of soil organic matter was found in costal area than other areas. The concentrations of available $P_2O_5$, exchangeable Ca, and exchangeable Mg were generally higher in mountainous, coastal, plain areas, respectively, but available $SiO_2$ and exchangeable K concentrations were not significantly different among the different topographic areas.

Korea is topographically and meteorologically prone to natural disasters. In addition to extraordinary weather, localized heavy rain is a irregular occurrence. Korea are frequently damaged by rain, wind, flood, etc. Recently, slope failures are disastrous when they occur in mountainous area adjoining highways. The accidents associated with slope failures have increased due to rapid urbanization of mountainous area. Therefore, the inspection of slope is conducted to maintain highway safety as well as road function. We developed basic function and risk management of a partial shape on highway slopes based on the internet. It is important for quantitative risk evaluation of highway slopes.

Since mountainous area has access restrictions for field work, assessors need to establish a conceptual model of the contamination prior to the field investigation. In this study we established a conceptual model of the contamination based on site inspection and geological survey, followed by the field investigation for the petroleum spill site. In the conceptual model, we estimated that tile contamination should have spread by groundwater and topographical characteristics within the top soil layer. The spread of contamination through rock was not considered in the conceptual model due to impermeable characteristics of metasyenite. The contaminated environmental media of the petroleum spill site include soil and groundwater. According to the analysis result of the contamination, the volume of contaminated soil is estimated approximately 4, 150 cubic meters (7, 055 ton) with most contaminants existing along the groundwater flow within top soil layer.

The purpose of this study is to estimate the low-flow statistics at the mountainous watershed. The formulation for the estimation of the design low-flow statistics was obtained by means of a hydraulic approach applied to a simple conceptual model for a mountainous watershed. Three of the independent variables associated with the low-flow statistics is watershed area(A), average basin slope(S) and the base flow recession constant(K); Watershed area was measured from topographic maps and average basin slope is approximated in this study using Strahler's slope determining method. And base flow recession constant computed using Vogel and Kroll's method. Unfortunately, this method is usually unavailable at ungaged sites. In this study, recession constant at ungaged sites is estimated using graphical regression method used by Giese and Mason. The model for estimating low-flow statistics were applied to all 61 catchments in the Sumjin, Mankyung basin.
