Influence of a shallow undersea reef on water mixing in coastal channels

Prostornim matematičkim modelom analizira se turbulentno miješanje u jadranskim priobalnim kanalima srednjih dubina, uz nepravilnost morskog dna poprečno na prevladavajući smjer morske struje. Proučava se hidrodinamički utjecaj prepreke na procese lokalnog homogeniziranja stratificiranog mora u području u kojem se planira dispozicija otpadnih voda. Rezultati su uspoređeni s poznatim funkcijskim odnosima koji opisuju turbulentno miješanje u slojevima stratificiranog fluida.The turbulent mixing in Adriatic coastal channels of medium depth, characterized by irregular sea bottom positioned transverse to the dominant direction of sea currents, is analyzed by a mathematical space model. The hydrodynamic impact exerted by obstacles on local stratified-sea homogenization processes in the area destined for waste water disposal is examined. The results are compared with known functional relationships that describe turbulent mixing in stratified fluid layers
