영문 초록

The evaluation of raingauge network is important to estimate the area average rainfall and the radar rainfall calibration for flash flood warning in mountainous areas. Basically, the necessary criterions for accurate area average rainfall estimate and flash flood warning are the uniform spatial distribution of raingauge network. This study has evaluated the raingauge network which is considered the spatial distribution and the density of rain gauge by altitude. The Euclidean distance method is adopted to consider the spatial distribution and the density of rain gauge by altitude for satisfying the both criteria, and is applied to 5 river basins. The spatial distribution of rainfall network is quantified by the nearest neighbor index and the characteristic of installation altitude is evaluate by CV(Coefficientof variation) of equal-altitude-ratio of the density. As a result, it can be found that Namgang Dam basin is excellent in uniformity of the spatial distribution and the density of rain gauge by altitude. Furthermore, the evaluation of persuasive raingauge network will be possible if the raingauge network is evaluated by the installation objective of regulatory agency.
