Abstract
The flow condition in bionic fishway of the low-head junction was studied by the scale of 1:20integrated physical model test.First,the design flow velocity which was suitable for domestic fishway was confirmed by the research of the main fish object of domestic fishway.Then through integrated physical model,the study on the changes of hydraulic factors such as different water levels between upstream and downstream of the hub,water level along the fishway,slope and flow velocity was carried out.The test results were analyzed,and the fish-in structure,bottom elevation,total length,slit width and pool room number of fishway were gradually optimized.Then the layout plan of low-head junction and bionic fishway was obtained which was suitable for domestic fish.关键词
