| Abstract |
In recent, we have a growing interest in the wash land construction as a measure of flood control and as a wetland with ecological function in the river. This study performed the flood control analysis and investigated the ecological effect for washland construction plan in Topyoung-cheon basin in Changyeong-gun, Gyeongnam. Several cases were considered for the washland construction on Topyoung-cheon basin, and we analyzed flood stage reduction and flood inundation for each case. From the result of flood control analysis, we found some significant results according to the combination of each wash land case. We also found that the wash land construction gave the positive results in biodiversity. Therefore, it will be desirable to consider various effects such as flood control, ecological aspects, and so on for the wash land construction. |
