The subject of this study is 3D modeling of density changes and double diffusion of salinity and temperature in a marine rectangular basin with closed boundaries and none-level bottom on longitude: 47º to 58º E and latitude: 24º to 30º N. Basin bottom is elliptical and non-level, maximum depth in center of bottom is 116.95m and increasing distance of center, decreasing in depth and minimum depth is equal to 35.07 m. Basin bottom is rectangular and non-level bottom and inversion. Minimum depth in center is equal to 6.58 m; away from center, depth increase to maximum equal to 112.77 m. It is considered in 5 layers in spherical coordinate with sigma vertical component and wind blow steady all over basin surface during 4 days. Results show quality of changes in diffusion of temperature and salinity each layer along longitude and latitude.
