Preliminary study of rainstorm-runoff generation-confluence and flood warning for small river basins in southern mountain areas
Due to the impact of topographical and geological conditions,short duration heavy rainfall is easy to bring sudden flood to small river basins in mountainous areas.Beijiang River basin is one of the rainstorm center areas of Guangxi.Peixiu Hydrological Experiment Station in Rongshui County is located on Peixiu River,a tributary of Beiji-ang River.Based on the precipitation,water level and flow measuring data of Peixiu Station,the authors studied the rainstorm,runoff generation and confluence in small Peixiu River basin,analyzed the change law of runoff genera-tion and confluence characteristics of small river basins in southern mountain areas,drafted a small river basin flood warning scheme by methods of multiple regression and rainfall-runoff,which laid a foundation for the rainstorm-runoff generation-confluence-evolution and flood warning in Beijiang River basin.
