EFDC이란? | EFDC는 미국 버지니아 해양연구소에서 1992년에 처음 개발하여 2007년에 완성된 연구용으로 인터넷에 소스코드가 일반인에게 공개된 환경해석을 위한 종합 수치모형이다. | |
2차원 중앙입경 퇴적모형의 단점은 무엇인가? | 지금까지 군산항 및 금강하구에 대한 퇴적계산은 2차원 퇴적모형이 사용되었고, 흐름, 파랑, 부유사, 소류사 및 퇴적고 계산을 각각 별도의 모형으로 중앙입경(D50)을 토사 대표입경으로 사용하여 계산하였다. 그런데 2차원 중앙입경 퇴적모형은 금강하구역과 같이 담수 유입 및 외해와 강으로부터 여러 등급의 토사가 유입되는 복잡한 수리현상과 퇴적과정을 반영하여 유사 퇴적고를 계산하는데 한계가 있고, 그 계산이 여러 과정으로 나누워 있어 번잡하여 능률이 저하된다. 그래서 실제 현상에 보다 접근할 수 있고 보다 효율적인 퇴적고 계산을 위해 3차원 다중 입경모형이 유용하게 된다. | |
EFDC(Environmental Fluid Dynamics Code) 모형을 개발 관리하고 있는 곳은? | inp)을 중심으로 기타 입력파일들을 그 지역에 맞게 새로 작성하여 모형을 운영할 수 있다. 현재 United States Enviromental Protection Agency와 Tetra Tech. Inc. 및 Dynamic Solution Inc.에 의해 개발 관리되고 있고, 전 세계적으로 환경동역학 문제를 연구하고 해결하는데 활용되고 있다. |
