ANALYSIS AND EVALUATION OF DESIGN WATER LEVELS ALONG THE COAST OF VIETNAM USING OBSERVED DATA AT SEVERAL OCEANOGRAPHIC STATIONS

Tóm tắt

The article presents the results of water level characteristics (tidal water level, meteorological surge) at monitoring stations in the past 30 years. Analysis of extreme values corresponding to probabilities at observational stations comparing the design water level of sea dikes from Quang Ninh to Kien Giang (available in Vietnam Standard TCVN 9901:2023) shows a very large difference, the larger the recurrence period, the larger the water level difference. In particular, at Hon Dau station, Hon Ngu station and Vung Tau station, the design water level according to Vietnam Standard (TCVN) is higher than the analysis from measured data, on the contrary, at Son Tra and Quy Nhon stations, the water level according to Vietnam Standard TCVN 9901:2023 is lower than the design water level from observed data.
