Znachitel'naya ploschad' Onezhskogo ozera obuslavlivaet shodstvo rel'efoobrazuyuschih processov na ego beregah s analogichnymi na morskom poberezh'e. Sledovatel'no, dlya Onezhskih beregov opredelyaetsya otnositel'nyy vozrast, chto predstavlyaet i teoreticheskiy, i prikladnoy interes, tak kak ot etogo zavisit intensivnost' dinamicheskih processov i ustoychivost' beregov. Poslednyaya naibol'shaya dlya beregov, nahodyaschihsya na stadii yunosti (dlya nih aktivnye processy esche ne nachalis') i stadii starosti ili dryahlosti (oni uzhe prakticheski zavershilis'). V svoyu ochered', ot intensivnosti dinamicheskih processov zavisit ob'emy postupleniya zagryaznyayuschih veschestv, v chastnosti, tyazhelyh metallov. Provodimye v techenie neskol'kih let issledovaniya vkupe s analizom literaturnyh dannyh pokazali, chto abrazionnye processy yavlyayutsya vazhnym istochnikom ih postupleniya v vodu ozera.Opredelenie stepeni ustoychivosti berega i prognoz ego dinamiki vozmozhno osuschestvit' metodom postroeniya profiley dinamicheskogo ravnovesiya i sopostavleniya ih s real'nymi profilyami podvodnogo beregovogo sklona. Vyyavleno suschestvennoe otlichie drug ot druga bol'shinstva ih nih, chto ukazyvaet na slabuyu stepen' ustoychivosti znachitel'noy chasti beregov, tak kak profil' podvodnogo beregovogo sklona stremitsya k profilyu ravnovesiya. Proslezhivaetsya zavisimost' konfiguracii profiley ot morfogeneticheskih tipov berega, kotoryh dlya Onezhskogo ozera vydeleno sem': pervichnye, abrazionnye, abrazionno-akkumulyativnye, akkumulyativnye, lagunnye, del'tovye i antropogennye.
