Residence time in 3 waterbodies (3.5MB zip file)

Animation of reservoir “age”.  Reservoir age is initially zero and all inflow has age zero.  Age at each location in the reservoir is incremented by 1 timestep on each timestep, and age is subject to transport just like any other constituent.  This produces a movie of cell residence time that provides insight on where the water in the reservoir is spending its time
