SUMMARY
Lag time in a hydrograph refers to the duration between the center of rainfall and the center of the hydrograph. This concept is crucial for understanding how quickly water reaches a river, contributing to maximum discharge levels. The discussion highlights a potential labeling error in figure 755, suggesting that the lag time should be indicated at the beginning of the graph, represented by the green line. Additionally, the use of the variable "N" in figure 6.5 is clarified as a means to estimate the transition from Direct Run Off to baseline flow in a natural basin.
