The College of Education for Pure Sciences in the Department of Mathematics at the University of Basrah discusses the use of the Clarken method to solve the Boysnick model to describe the process of mixing and rotation in Khor Al-Zubayr, which is located in the northwest of the Arabian Gulf.
 The letter presented by the researcher (Sajjad Kazem Jaseb) included
Where the study area was distributed into five sections to describe the process of mixing and rotation by solving the Boysnick model using the finite element method and comparing the results with field measurements of salinity and current speed. The study is the first in Iraq in which the Poisink model is solved using the finite element method to describe the mixing and rotation process

Matching the field results with the calculated results using the Poison Model by 97%.
