中小急流河川における護岸粗度の抵抗特性に関する一考察

Steep gradient revetment is used in general for the countermeasure of flood control structure after the damage by disaster on small-and-medium-sized rivers of rapid flow. However it happens sometimes to make stream channel erosion around the revetment at river channel of single section. It is not clear that roughness of steep gradient revetment effect the local velocity around revetment. This paper presents some results of an experimental investigation with artificial strip roughness for the purpose of friction characteristic of revetment roughness.
