[0041] In other possible implementations of the above model, the items can be defined. In this implementation, the specific definition of water age is the time taken for the tracer to reach the specified location after leaving the area where the water age is defined as 0. In research, the water age at the water body entrance or upstream boundary is usually defined as 0.
