Efdc the efdc model
EFDC 모형The EFDC Model

  • EFDC(Environmental Fluid Dynamics Code)는 범용적 목적으로 만들어진 모형패키지이다.

  • The Environmental Fluid Dynamics Code (EFDC) is a general-purpose modeling package

  • 1,2,3차원 모의흐름, 이동, 수 표면의 생물지구화학적 처리공정 (강, 지류, 호수, 하구, 연안과 대양)

  • Simulates 1,2&3-D flow, transport, and biogeochemical processes in surface water systems (rivers, streams, lakes, estuaries, coastal waters and open ocean)

  • EFDC 모형은 원래 버지니아 연구소의 해양과학 연구소에서 개발되었다.

  • EFDC model was originally developed at the Virginia Institute of Marine Science

  • EFDC 누구나 사용 가능하게 공개된 모델이다.

  • EFDC is a public domain model

  • EFDC_DSI 는 국제적으로 동역학적 개선 및 최적화한 버전이다.

  • EFDC_DSI is Dynamic solutions-International’s enhanced and optimized version

Water Quality





  • EFDC의 수치해석은 3차원 유압식을 공식화를 기초했는데, 곡선형방식과 수직방식으로 도식할 수 있다.

  • EFDC’s hydrodynamics are based on the 3D hydrostatic equations formulated in curvilinear-orthogonal horizontal coordinates and a sigma or stretched vertical coordinate system

  • EFDC는 모형의 연계문제를 제거한 결합모형입니다.

  • EFDC is a coupled model eliminating model linkage issues

Efdc explorer what is efdc explorer
EFDC_Explorer란?What is EFDC_Explorer?

  • EFDC_Explorer (EE) 는 EFDC와 DSI 두 가지 버전에 의해 개발된 전-후 처리 도구:

  • EFDC_Explorer (EE) is a pre- and post-processing tool developed by DSI for two versions of EFDC:

    • EFDC_ DSI (기본 모형)

    • EFDC_ DSI (Primary model)

    • EFDC_GVC/EFDC/EPA (기존 응용프로그램)

    • EFDC_GVC/EFDC/EPA (Legacy applications)

  • EE7 모델링 프로세스를 간소화:

  • EE7 significantly streamlines the modeling process:

    • 모형입력준비

    • Model Input Preparation

    • 2D GIS 형식 정보를 사용자가 모델의 입력을 정의하고 편집할 수 있다.

    • User of 2D GIS type information to define and edit model inputs

    • 상황에 맞는 포인트 및 셀 속성, BC할당에 대한 액세스를 클릭한다.

    • Context Sensitive Point & Click access to cell properties and BC assignments

  • EE7 는 이전버전인 EE보다 훨씬 개선되고 간단한 인터페이스를 제공한다.

  • EE7 provides a significantly enhanced yet simpler interface than previous versions of EE.
