Abstract |
In this study, it were evaluated areal floods by frequency floods in river plan reports. The correlations between the river basin areas and the design floods were showed at least 0.94. The results of frequency areal floods by 923 points were appeared to 11.66∼24.45 ㎥/s in Anseong city. The correlations between probability rainfalls and frequency floods were appeared more than 0.94. In the hydrological data 20, 30, 50, 80, 100 and 200 years , respectively, 11.66 ㎥/s, 12.78 ㎥/s, 14.01㎥/s, 15.14 ㎥/s, 15.67 ㎥/s, 17.33 ㎥/s were analyzed, in the case of Small Rivers 20, 30, 50, 80, 100 areal flood frequency ratio is 18.67 ㎥/s, 20.11 ㎥/s, 21.80 ㎥/s, 23.46 ㎥/s, 24.45 ㎥/s indicated by the ratio of the Small rivers areal flood appeared larger than the local rivers. By using a design review hydrological data analyzes presented in this study it is expected to provide the resources to help you prepare flood of Anseong city. |
