Sootnoshenie stoka vzveshennyh nanosov i rastvorennyh v vode veshestv
Interesno sopostavit' razmery stoka vzveshennyh nanosov so stokom himicheski rastvorennyh v vode veshestv. Takoe sopostavlenie pokazyvaet, chto na ravninnyh rekah stok himicheski rastvorennyh v vode veshestv znachitel'no prevyshaet stok vzveshennyh nanosov.
Esli summarnyi stok vzveshennyh nanosov himicheski rastvorennyh v vode veshestv prinyat' za 100%, to stok poslednih na ravninnyh rekah lesnoi zony Evropeiskoi i Aziatskoi chastei SSSR sostavlyaet v srednem 65-85%, a lesostepnoi i stepnoi zon (Don, Ural) primerno raven 40-50%.
V gornyh raionah sootnoshenie rezko izmenyaetsya. Zdes' na dolyu vzveshennyh nanosov prihoditsya do 90% (tabl. 29).
