Title: A review on base-flow calculation and its application
Abstract: Base-flow is the base river runoff supplied by groundwater.With features of sustaining a stable ecological system,exact calculation of base-flow is of important significance in eco-environmental problems of river cut off,land subsidence,shrinkage of lakes,degradation of vegetation,and so on.The focus of this paper is on the definition of base-flow,research importance,types of calculation methods,evaluation of application scope and prior developmental direction of these methods.The calculation types can be classified into graphic analysis method,numerical simulation method,hydrological modeling method,physical chemistry method and mathematical physics method.The paper places its emphasis on the base-flow application into calibration and validation of models,water resources management,ecological water demand,sediment transportation and ability of river self-purification.The research results can provide an important reference in base-flow calculation and its application in other fields.
