05. STUDY CHARCTERISTICS OF HYDRODYNAMICAL AND MORPHODYNAMICAL REGIMES IN THE NHAT LE ESTUARY AREA, QUANG BINH, USING DELFT3D MODEL

Lan Nguyen Hong, Cham Dao Dinh, Lan Vu Van

Giới thiệu

This work presents the hydrodynamics and morphodynamics regimes of the Nhat Le estuary based on the collected data and numerical simulations using Delft3D model. Based on a numerical model, the main physical processes governing estuary morphology, including tides, waves and freshwater runoff, have been simulated and analyzed for better understanding the morphological evolution of the estuary. The simulation results showed that the study area has quite similar tidal regimes, most of which have irregular diurnal properties; storm and monsoon surges in this area often occur during the year; the time of rising water due to the monsoon lasts from October of the previous year to March of the following year, the highest is in December, coinciding with the period when the dominant wave direction is the northeast, accounting for over 60% with height of 1.25 m, directly affects the shoreline causing coastal erosion in the South Central Coast.
