Residence Time. Mean Water Residence Time (aka: turnover time, age of water leaving a system, exit age, mean transit time, travel time, hydraulic age, flushing time, or kinematic age). T. . = V. . 7.1 Components of a natural hydrograph. The various contributing components of a natural hydrograph are shown in figure 7.1. To begin with there is baseflow only; that is, the groundwater con­tribution from the aquifers bordering the river, which go on discharging more and more slowly with time. The hydrograph of baseflow is near to an exponen­tial curve and the quantity at any time is represented very nearly by:. Rami. . Harfouch. Surface Water Hydrology.
