Abstract

Replacement of water in a given hydrological component is one of the effects of the hydrological cycle. We introduce the concept of renewal time to express the rate of water replacement in a specific reach of a river. Based on stream‐flow data from the 1990s, a simple formula is used to estimate renewal times for several reaches in the middle and lower sections of the Yellow River (Huanghe) in China. These estimates reveal the following trends: (i) renewal times are shortest during the May–October period and (ii) annual renewal times tend to decrease when moving downstream from the middle to lower reaches.

In the past 30 years, the measured annual river flow of the Yellow River has declined significantly. After adding the diverted water back to get the 'natural' annual river flow, the tendency of decrease can still be seen. This indicates that the river flow renewability of the Yellow River has change
