Block diagram of the AYRS water regime

In the common case, the vertical structure of the river water area in (k = 1. N) is described by block SES (Krapivin, 1995). A snow layer of thickness gk is formed at the expense of flow Bk according to  

The functional representation of the other blocks from Table 6.15 

The z/th radionuclide is characterized by its half-life tv, by the rates Hkv of input to and output from area Qk(k = 1. N), and by the concentrations of Qv, Ev, Ev, and Sv in the water, soil, sediment, and ground water, respectively. As a result the main balance equations of the RAK block can be written in the form  

Flows Hiv (z = 1. 12) can be parameterized by linear models according to Krapivin (1995) and Nitu et al. (2000a). The BIO and CPK blocks are described by similar balance models in analogy with the models described by Somes (1999) and Kram (1999). AYRS biology is given in the form of a scenario or is described by 

Approximate solutions to the initial value problem for Equations (6.17)-(6.29) are realized by means of the quasi-linearization method (Nitu et al., 2000b).
