  • 우리나라 벼농사 농작업의 대형기계화 추세에 따라 논 배미의 크기가 소규모에서 1 ㏊이상 대구획으로 재경지정리가 시작되고 있으며 3 ㏊이상의 벼농사 경영규모를 가진 농업인이 점점 증가하고 있는 경향이다. 그러나 우리나라에서는 아직까지 대규모 벼농사 기계화 작업체계와 기술이 확립되어 있지 않은 실정이다.(중략)

  • A one-dimensional flood routing model was formulated to simulate the flood flow of drainage sub-canal using the continuity equation of paddy field and the momentum and continuity equation of drainage sub-canal. The model was applied for evaluating the hydraulic characteristics of drainage sub-canal at large-sized paddy fields. The model applicability was evaluated with field data and the simulated results were in good agreement with the observed data.

  • A two-dimensional numerical model based on a finite volume method was formulated to solve the shallow water equations and applied for evaluating irrigation and drainage characteristics at large-sized paddy fields. Manning roughness coefficient was calibrated using the observed inundating depths at drainage tests and used for validating the model with the results from irrigation and drainage test. The simulated results were in good agreement with the observed inundating depths.
