Three-dimensional computational modelling of water cooling over the coastal slope: a comparison of hydrostatic and non-hydrostatic solutions



This article addresses the structure and dynamics of current and temperature fields in the coastal zone of a large water body generated by seasonal variations of heat-exchange conditions at the water surface. Numerical solutions of three-dimensional hydrostatic and non-hydrostatic models MIKE3-FlowModel in shallow and deep parts of the basin are compared. It is shown that the structure of fields is reproduced adequately by both models and water currents are similar; however, the hydrostatic model produces a smoother current field and significantly larger horizontal temperature gradients.
