Na osnove dannyh naturnyh nablyudeniy, poluchennyh v 2017 g, issledovany lokal'nye osobennosti granulometricheskogo sostava plyazhevyh nanosov i donnyh osadkov na uchastke beregovoy zony v rayone peresypi oz. Sakskoe. Proanalizirovana vzaimosvyaz' prostranstvennogo raspredeleniya razlichnyh frakciy i dinamiki shiriny plyazha na uchastke razmescheniya beregozaschitnyh sooruzheniy. Poluchennye rezul'taty pokazali, chto plyazhevye nanosy postepenno preodolevayut kaskad suschestvuyuschih beregozaschitnyh sooruzheniy v sostave srednego potoka nanosov i dolya krupnozernistoy frakciy zametno sokraschaetsya v severnom napravlenii. Dinamika linii ureza zavisit ot intensivnosti i napravleniya shtormovyh voln, opredelyayuschih harakteristiki migraciy nanosov razlichnoy krupnosti. Posle prohozhdeniya shtormov naibolee suschestvennye izmeneniya polozheniya beregovoy cherty i granulometricheskogo sostava nanosov nablyudayutsya s protivopolozhnyh storon kazhdoy iz suschestvuyuschih bun. V mezhbunnom prostranstve proishodit formirovanie dostatochno obosoblennoy litodinamicheskoy yacheyki, v predelah kotoroy summarnoe kolichestvo plyazhevogo materiala i ego sostav suschestvenno ne izmenyayutsya. Rezul'taty analiza prob grunta s poverhnosti dna pozvolili vydelit' granicy zon rasprostraneniya graviynoy, peschanoy i alevrito-pelitovoy frakciy. Poluchennye dannye mogut ispol'zovat'sya v kachestve vhodnyh parametrov dlya cifrovyh modeley i raschetnyh metodik pri poluchenii prognoznyh ocenok pereformirovaniya beregovoy zony v rayone peresypi oz. Sakskoe.
