The objective of this study is to understand characteristics of salinity intrusion and its relations with river fresh water discharge and tidal fluctuation in the Mekong River, through field measurements and numerical simulation. Field observations and calculations have been done for the Mekong River and the Tieu River which are considered the most vulnerable to salinity intrusion in the Mekong delta.<BR>ADCP and TPM were used to measure river discharges, morphology and water qualities (salinity and turbidity) along the rivers. Though measurement term was in seven days, salinity intrusion particularities were found out. The mixing pattern of the Tieu River in dry season was identified as a strong mixing type. Tidal discharge was much larger than freshwater discharge. Based on observed data, numerical analysis was done. By correction of water level at Vam Giong, the suitable values are-41cm lower than observed ones. Referring to regressive curves, the averaged river discharge is proportional to the averaged water level difference. The salinity peak occurs one month earlier than the peak of water level difference and river discharge.
