The Use of Residence Time to Describe a Hillslope

Part of: Engineering Hydrology


Queueing theory has been applied to the determination of Soil Water Residence Time (SWRT) using an 18 year data set. The calculated SWRTs agree qualitatively with the lags exhibited by a 12 month running average plot of rainfall and streamflow. The characteristic SWRT curves derived for two parts of the record agreed well with each other, in spite of a significant drought during the later period.
