| Abstract: |
| In this paper, dynamic pressure formed near overflow spur dike under different channel roughness, different flow constriction proportion, various discharges and depths are studied. Several basic characteristics on pressure distribution at the surface of spur dike are described. According to test data, practical calculation formula(5) applicable to spur dike are presented. |
