Abstract
In this paper, an improvement method has been investigated for the practical application of nearshore current analysis using Hardy-Cross method. For this purpose, applications of concentric rectangular circuit correction, initial value insertion using coarse grid, and multi-grid method are introduced.
As a result, it is clearly understood that the slow-convergance problem of Hardy-Cross method can be solved with much accurracy. In addition, the method which can be applied to The case of the presence of the non-water zones is also investigated.
