Therefore it deserves scientific attention. The processes under concern are studied using a combination of very few available observations (water levels and oceanographic data), remotely sensed data as well as numerical modelling approach. The numerical simulations are performed using the three-dimensional modeling system Delft3D, developed by WL | Delft Hydraulics. The first part of the present thesis investigates the tidal characteristics in the Red Sea. The RS-Model suggests that the dominant pattern in the region is primarily semidiurnal with the appearance of diurnal character at places where amphidromic systems are established. The second part of the thesis concerns the seasonal circulation patterns and thermohaline structure in the Red Sea. The most important feature during winter period is eddies activities located in the northern part of the Red Sea that contributes significantly to the formation of the Red Sea Outflow Water (RSOW).The results suggest that the northern part of the Red Sea is the dominant formation site where baroclinic instability mechanism controls the formation process. In the third part of the thesis, the relative importance of wind and thermohaline forcing on the key circulation features is investigated through additional numerical experiments. The numerical experiments showed that the wind-driven circulation is stronger and dominates the themohaline driven-circulation.}, url = {https://macau.uni-kiel.de/receive/diss_mods_00020639}, file = {:https://macau.uni-kiel.de/servlets/MCRFileNodeServlet/dissertation_derivate_00007028/Thesis_Copy.pdf:PDF}, language = {en} }
