A hydrodynamic numerical model, ESCORT, which enables wetting-and-drying simulation, is developed. The model is verified by applying it at the Mokpo coastal zone together with the MIKE21 model. This paper deals in only 2-dimensional aspects remaining 3-dimensional function for further research. To begin with, MIKE21 model is applied at the whole area where MIKE21 had been applied several times to produce boundary conditions for the main area. Unlike the whole area of uniform grid, main area adopts telescoping grid for ESCORT model and nested grid for MIKE21 model. The results of both model show not only good agreement for the values of water depth and tidal velocity between computed and observed ones, but also plausible wetting-and-drying simulation. However, ESCORT model needs some improvement of efficiency.
