전체 글 썸네일형 리스트형 매닝조도계수 매닝조도계수 [Manning粗度係數, Manning’s roughness coefficient]수로의 벽면의 거칠기 성질에 의해 결정되는 계수 상세설명흐름이 있는 경계면의 거친 정도를 나타내는 계수로, 수로를 구성하고 있는 면의 성질에 의해 결정된다. 여기서, v는 유속(m/sec), n은 매닝조도계수(coefficient of roughness)이며, n값은 0.009~0.014 까지 다양하게 분포되어 있다. R은 동수반경, I는 동수경사이다. 더보기 SWMM 5 Error Messages - Run Time Errors SWMM 5 Error Messages - Run Time Errors ERROR 101: memory allocation error.
