| Abstract: | Based on water flow movement characteristics in film hole irrigation, a zero inertia model form surface water flow movement in film hole irrigation were presented in this paper. With combining optimization method, an optimal model of determining synthetic surface roughness coefficient in film hole irrigation was developed. Case study indicated that the model is simple and effective. |
