Abstract Streamflow can be separated into fast runoff and baseflow according to pathways, also new old water storage times. Typically, does not completely overlap with water, nor water. This imperfect relationship divides total streamflow four components. Separating the fractions of these components is an important prerequisite for understanding hydrological processes. However, current separation methods are still inadequate accomplish this task, most them only separate two Therefore, we developed a hydrograph method that couples mass balance nonlinear storage‐discharge relationship. achieve simultaneous based on inexpensive tracer electrical conductivity (EC) without need precipitation data. The applicability was tested at 51 gages in continental United States, which have high‐quality EC data widely hydrologically representative. results show applicable small‐to medium‐scale natural watersheds across wide range climatic, vegetative, geologic zones. added consideration impacts passive water‐rock interaction significantly increases reproducibility leads more similar separation, fact significant differences due distinct they contain. has well‐defined physical basis expanded several practical applications.
